You're an idiot. Why do we need two of these threads?

>>1701435
Remember, spamming/flooding also applies to retards that can't use the catalog or thinks they're to important for it.

>>1701435

If you link me to it, I'll delete my thread.

>>1701407
if it's a linear supply, then likely the output transistor fried
should be easy to find even without schematics since it will be driving the output, and probably will have a beefy heatsink

confirm the damage by checking if draing and source are shorted, you can do it in-circuit
then find replacement and hopefully that will fix it

Got this older burgerland toilet made by Eljer.... Need to replace the tank to bowl parts but want to replace most of the parts while I'm at it. It looks like the Hygeian series but the guts are different from any tank I've seen and I can't seem to figure out what I need to order...

>>1701624
Thanks I'll check the transistors

I'm decorating for Halloween.
I'm painting shit on newspaper and cardboard and hanging it up in my entryway, I've got glass windows in the doors so I was planning on putting red lights behind them to have light shine through the paper.
Attached is what I've got so far, any suggestions?

I want to make custom onaholes.
Where can I ask about this since /diy/ is SFW?

>>1701624
I checked both these transistors. The "open" one is KDS301 90. Is that supposed to remain open until it overheats, and then close?

I can't read the other one but it is closed.

I know these are not the power transistors, I'll check those next.

>>1702518
The closed one

>>1702518
>>1702520
those are thermostats

>>1702518
>KDS301 90
Normally closed
Opens at 90° C

>>1702550
would they be duplicates of each other?

>>1702558
>would they be duplicates of each other?
Are the numbers the same on both?
If the numbers are different, the specs are different.

Also: it's KSD not KDS

>>1702560
I can't read the numbers on the second one

Can torque limiter break down on cordless drill?
I suspect my 12V Makita did exactly this

>>1701821
Try /b/; they're 4chans resident experts on onaholes.

>>1703006
The clutch? Yes, those are often one of the earlier things to break. A lot of times the mechanism inside gets fucked and they just jam up.

I've got an old antenna in my attic with twin lead running down a wall to the room directly under it. Currently I've got it hooked up to my TV with a balun, the typical 2 screws and an unthreaded female F connector.

Reception seems exceptionally poor. In the other room, we have a small amplified antenna, $20 off the shelf thing from last year, and it gets twice as many channels. Different brand of TV but both TVs are cheap flat panels.

If I wanted to get serious about this, would I get better reception by converting to coax with a balun on the attic antenna and running the coax to the TV? Or does the other TV get better reception just because it's powered? Is there something else that's cheap that I can do to improve the attic antenna's reception?

>>1703023
It feels weak. Drill is 2 years old, btw.
But looks like it still can hold torque in drilling mode.

>>1703032
Generally, the digital conversion sent most broadcasters to UHF bands.
This is why the small, flat plates in the window work.
The antenna in the attic is probably tuned for VHF.
Make sure it's pointed at the station you want to receive.

>>1703047
>>1703047
So you’re saying in driving mode it slips really easily whether you have it set on 1 or 20? But then everything still locks up fine when you go into drilling mode?

Sounds like it’s fucked. I had one of mine get all jammed up, but yours sounds like a slower death. At least the drill still works. If it’s one of the major brands, you can probably buy a replacement for whatever little plastic plate or spring is going to shit, but it might not be worth it if the thing is getting old. Just wait until the trigger gets 100% fried and replace it with a new model.

Pic related is an old fucked DeWalt that took one too many crashes off the ladder. The clutch mechanism is that white plastic, this one has little ball bearings on springs IIRC, so I’m sure the plastic carrier or springs or bearings are part dust.

>>1703047
>>1703076
Depending on the drill, good luck. This ol’ DeWalt, the chuck was not coming off with any T-20 bit I had around. I wish I didn’t sacrifice that socket bit, I didn’t even put that much torque on the 1/4” ratchet.

>>1703076
>So you’re saying in driving mode it slips really easily whether you have it set on 1 or 20?
Not quite.
I'm not sure if it was like that, but at 18 (maximum torque limit) I can easily stop the clutch with hand. Not sure if it was like that when it was new though. At minimal torque limit, I can stop the chuck with two fingers. I'm not sure, if clutch gets weaker, or I got stronger after tiny renovation...
> But then everything still locks up fine when you go into drilling mode?
Yep, I can stop the motor in low gear and it will not slip.
>Sounds like it’s fucked
It can be, because last time I was using clutch too much (i.e. was holding trigger for 2-3 seconds like retard while it was clicking)
>If it’s one of the major brands, you can probably buy a replacement for whatever little plastic plate or spring is going to shit
I think it is done via steel balls and springs, and some special metal plate with wedges.
Since it is Makita, I think I can buy new gearbox. But. I can do it anytime. I heard people have similar issues with hammer (rotary, thing where you have "drunk" ball bearing and pneumatic magic) drills, and people used dremel to change profile of teeth, so it doesn't disengage the load.... I wonder if similar shit is possible here.
Or do it ghetto style and pre-load big spring
> Just wait until the trigger gets 100% fried
Nonono, until batteries or motor die I won't do anything. Fried switch is no big deal since FET is discrete.
>The clutch mechanism is that white plastic, this one has little ball bearings on springs IIRC, so I’m sure the plastic carrier or springs or bearings are part dust.
Yep. But I'm 100% sure it is metal wear in my case, since plastic would jam the shit and fry the motor.
>>1703086
This is fucking crazy. I think those bastards use red loctite or something on that left thread bolt.

>>1703090
Yep, that is gear box dying.
But I found ghetto fix. I just assembled and disassembled the thing, and it started working better. I don't know what I did, probably somehow increased pre-tension.

Anyway, how do I remove fucking left threaded bolt? With another drill?

>>1703062
The attic antenna can't make up for it with size?

It's also old and it's been up there for like 30 years. I haven't looked at it lately. Is there a good chance the terminals are just corroded to shit?

>>1703136
>The attic antenna can't make up for it with size?
This is probably not a good way to put it but, think of the antenna as a tuning fork.
If it's the wrong band (UHF vs VHF) it doesn't resonate at the right frequency.
The new antennas are 'tuned' to the new channel frequencies.
Some stations stayed on the same band but changed the mode of transmission from analog to digital.

It's in the attic so corrosion should be minimal but it wouldn't hurt to check it.

Don't knock it for being twin-lead. It has much lower loss than coax for the same length.

>>1703172
Well, the length is like 10, 15 feet? for the twin lead and the coax is just a six-footer.

I'm not against the twin lead per se, but it doesn't have the terminal forks for easy connection to the balun. They broke off at some point, so I've stripped them down a bit and twisted up the strands so the teeth on the balun terminals would have something to connect to. It seems solid enough. I also wish the balun was threaded, or had a male F connector.

Anywho, seems like my easiest and most effective solution would just get a plate antenna, but also it might be worth to find a way to hook up my attic antenna to my FM stereo since it's not going anywhere.

Thanks for the input, fellas.

>>1703172
related question, actually.

Would any old wire work to extend the twin lead if I just need like 4 more feet to reach the receiver? I've got some unused cat3 collecting dust, for instance...

>>1703086
>>1703090
>red loctite
Maybe. Or it’s one of those things that gets a little bit tighter every time you use it so it’s impossibly torqued now.

I’m a dumbass for using the socket, my autism is off the spectrum having a broken socket in my set. Ordered a new one for $4.50 off Amazon, not even worth trying to warranty it for that price. Shoulda spent $20 on the SK just to see if that is significantly better, but I’m sure that would break too.

>>1703195
>I just need like 4 more feet to reach the receiver?
use a length of coax from the balun to the tv
cable company coax or one of the short pieces that usually go from the wall plate to the tv

when reading about heavy machine tools, everyone will always say that aluminum extrusions, steel plate, etc shouldn't be used to frame things like lathes or mills because they don't have enough damping to negate the vibrations of using the tool, which will give you bad tolerances and surface finish. yet people like https://www.youtube.com/watch?v=Lzytexbrdlg are able to achieve good quality parts and high precision using scrap. how is this possible? I thought machine tool frames needed to be heavy for parts to be reasonably accurate.

I want to buy a miter saw for cutting steel pipe. With most videos I've watched of people doing this, there's a decent amount of sparks flying away from the tool, but they're always inside. Do I have to worry about this causing a fire? I have no garage or way to use this tool outside. I guess I could use a hacksaw or something but a miter is just useful to have anyway.

>>1703852
Get a cold cutting saw, and get an acutal metal cutting saw not a wood saw.

As for fire, yes, if its spitting sparks you got to worry about fire. Just shove a board behind the saw.

I have a question about PPR welding/fusion.
Can I use torch to weld those, or it is janky AF. I'm not going to buy an iron for one exposed joint.

Can anyone track down a schematic for a pcb for a Carrier FAU/furnace? The only numbers I could pull from it are HK42FZ061 and CEPL131012-20. I can only find replacement boards. It was damaged in a flood and now the HSI isn't receiving power. I'm positive the relay is damaged because it's flopping around but that whole section of the board is highly corroded. I want to replace a few other components but I may not be able to clean them up without damaging the markings so a schematic may help for getting values and determining polarity for some electrolytic caps. I'm sure it's out there but may only be accessible by service techs. I've found the relay already, $2.50 and I probably have the rest of the components on hand.

Can you clear coat over old machine tags like this? is rattle can clear coat even oil and chemical resistant? The plastic film has been eaten away by oil getting under it so I'm peeling it off and want to redo it but more permanently if possible. The tag is oil and solvent resistant, so it's not the cheap inkjet crap.

>>1703121
Go the opposite direction? What do you mean?

not sure whether to ask here or the electronics general, I'll try here first. my yamaha ypg-235 keyboard is fucked, I'll press C3 and G3 plays, pressing any key plays a note that's completely wrong. there is a pattern, it appears to descend for 3 or 4 notes left to right, before restarting that descent at a higher pitch. the two leftmost keys don't make any sound and the two rightmost keys produce the lowest and highest pitches.

It's not the intonation or whatever before anyone says that, I've already set it to "grand piano" mode which should just be a normal piano, and I've tried resetting the keyboard, first a soft reset and then a hard one. it still has the same aggravating pattern. what could possibly have caused this and how can I fix it?

Any plumbers here that can help me? i have a toilet with a concealed cistern that started leaking and i cleaned the inside and bought a new kit (identical to the old one, so i dont think i have the wrong fitting one). I installed the new kit but the toilet ist still leaking as the thing that goes in the wall is basically just a friction fit but i have no idea how to get it to seal properly it as far in as it goes.

Is there a simple way to convert a hand pump hydraulic cylinder to being able to be powered by an external pump? I don't mean pneumatic, I mean an electric motor powered hydraulic pumping unit.
Tried googling it but "convert hydraulic cylinder to hydraulic" is about as effective as you might guess.

>>1705154
I'd make sure there isn't a mechanical issue going on. Take it apart and activate the buttons without the keys. If you are still getting distorted notes I'm going to assume it's a problem with one of the chips, and you should just trash it. It's like a $100 keyboard.

I'm about to go through this with 2 keyboards myself. deadkeys are super common - I'll admit the distortion is odd, and maybe suggests a problem with the electronics. But gotta start somewhere, and I'd start by taking it apart and cleaning it out. I think there are like 100 goddamn screws in the bottom of that thing too. do a search for a service manual.

My door latch and bolt striker plates don't line up exactly. I have to pull the door everytime I need to lock it. Should I grind out the bolt plate or shim the inside of the latch plate?

>>1701407
My 20 year old jeep has an exhaust leak from a crack in the manifold. Should I bother to fix it? If I put some high temp jb weld, could it cause the crack to widen and make it worse?

>>1705835
>I have to pull the door everytime I need to lock it.
It's actually a little more secure like that.
Not being able to 'jiggle' the door when locked is good.
This has nothing to do with cases where they're going to just kick it in.
If it really bothers you, move or grind the striker plate.

Why does this happen? Had pictures on an SD card and now they're doing this/unreadable. It's not like they were on there for years. I've seen the same thing happen to data dvds.

Optical media is even worse if you don't intend to perform periodic disc backups.
Best would be double drives backup, raid configurations or cloud storage.

I could see that. Thing is I installed an electronic lock; so it needs to line up. Ended up taping 2.5mm worth of shim in the latch strike plate as a temporary fix until I figure the proper way to shim it.

How do you plan a "book" when you are not sure of the amount of information you want in it?
I'm planning on making a book of some sort with drawings of stuff and and facts about that stuff. Think a plant book.
I bought a blank book with 256 pages to fill. I will do it all by hand, both the drawings and the writing.
How should I start with this project? Leave some pages (5-10) in the beginning blank for stuff that might be needed later (table of contents etc)?
Should I draw and write directly in the book? Might get messy.
It will be somewhat of a personal book, but maybe I should write the sources for the information somewhere. Maybe at the end of the book? How much space will that take?

I changed a spare and the car jack was super rusty. I threw it into a bucket with some vinegar, and figured I'd brush off rust later. Now I'm second guessing myself.

Do I need to soak it in baking soda water after to neutralize any leftover acid?
I was going to use white lightning crystal grease - picked up for my bike a while ago and seems to do the job.

Need to fix a fairly hefty cast iron piece (only about 5/8" thick at the break but it's attached to another 5 lbs of iron) but don't have an oxy torch or tig or anything proper, just a ts8000 propane torch. I have some 4/96(tin) acid core 600f solder or I can get some 56/44(tin, copper, zinc) solid core 1200f brazing wire.
Will the acid flux cause any problems with cast iron? Or Will it make it easier vs external flux? How much stronger would the brazing wire be than the soldering wire? Would my torch even be able to melt the brazing wire?
It's a bearing bore that broke when trying to press out the bearing for replacement and it's a semi complicated shape (much more than I drew) and quite thick, replicating it in steel would kinda suck. The bore doesn't experience a real whole lot of lateral force, but there is some.

Just rinse it off real good and hit it with some wd40. Unironically the only thing it's good for.

>>1706161
That’s what those little + things are for. You can hang it off a small nail or screw.

Anyone familiar with building techniques on older homes? Mine is from the 30's. Located in Ontario. I am relocating the dryer vent and it needs to go through the rim joist. There is a cavity behind hid followed by cedar boards then the outside brick. Is it common to have this cavity? I wonder if it runs up to the second story of the house.. Would be great to fill it with insulation.

>>1706236
My bet is old Balloon style framing. That cavity is the stud bay that runs all the way to the top of the wall of the 1st story. Probably not to second story. That would be a long ass stud.

Easy to run wires or blown insulation cause no fireblock to interrupt. Oh btw you have no fireblocks in your walls.

>>1706209
ah, so I can just drill two into the side of my desk and then hang it?
thanks

>>1706283
Yup, that’s what they’re there for.

Find a screw with a head that just barely fits through the center and tighten them just enough so you can put the middle of the two “+’s” over the two screw heads and pull down and have it secure. I have my two drill chargers and a power strip hanging the same way on my workbench, that’s what it’s made for. And that one gives you 4 notches rather than the typical one direction so you can mount it any orientation you want.

Anybody know what the hell those little notches are called anyway? They must have a name.

I dropped a hammer on my kitchen floor and cracked a tile. Finally got around to pulling it up today and noticed that 2 of the surrounding tiles were cracked as well as a third one that wasn't touching the other ones. Other tiles around those were pretty loose to the point where I could pull them up by hand. The mortar is essentially dust. Floor is something like 3 years old.
I've scraped a fair amount of mortar up and what's left seems fairly solid. The surrounding tiles are pretty solid too.
Should I use regular large-format-tile thinset to stick these back down or some of that premix fortified stuff. I really don't want to pull the floor up all the way. Pic related is floor before I scraped the mortar.

So let's say some local idiot wants to do a small shingling project, but the weather is supposed to be ~45F for the near future. Would a 1500w heatgun to the tar strips be a good idea to make sure the shingles are adhering to eachother? Would there be a better option?

>>1706412
>Should I use regular large-format-tile thinset to stick these back down or some of that premix fortified stuff.
If you don't have anything on hand, use whatever is available in a small quantity.
Regular thinset works fine for repairs but if you have to buy a large bag of unmixed and can get the fortified premix in a small bucket for the same price why not go with the premix.

Either will work - go with lowest cost or least trouble.

>>1706412
>I've scraped a fair amount of mortar up and what's left seems fairly solid.

Me again >>1706430
I didn't notice that all of the mortar wasn't removed.
I'd take it down to the original surface as much as possible.

>>1706134
You can braze it, but a press fit bearing will break the joint.

>>1706198
Lol that’s funny about wd40. Literally only thing I’ve ever used it for is starting fires when I was a kid. Won’t it leave a crap residue everywhere?

>>1706146
Washed it off with baking soda and water, lubed it up and hopefully it won’t be covered with rust in a week. I use vinegar and steel wool to oxidize wood so I felt stupid the second I started cleaning off the rust with vinegar and steel wool...

>>1706431
Origional surface is under 1/2 in concrete board. I've scraped everything that's willing to come up.

Here it is done, not an exact match but I'll take it.

>>1706300
thanks so much anon. I was able to do it and now my desk looks much better. Thanks.

>>1706469
Nah, the shit doesn't stick around very long. It'll definitely be less greasy than if you greased it.

Also, the shit isn't nearly as flammable as it used to be.

>>1706479
>not an exact match
yeah, three years later it's hard to find the same tile.
I usually leave a few tiles from the job stored out of the way at the job site.

Your job is definitely better than cracked tile.
By the time your mismatched grout isn't noticeable the tile won't be either.

>>1706532
I actually had a whole box left over but I ended up using it on the basement stair landing(which is off the kitchen). This will either last forever or for 6 months. Worst part is that I had the money to pay my tile guy to do it at the time and I did it myself instead. The $600 would have been worth the lack of headache.

>>1706524
so when I look up WD-40, I'm told it is useful for cleaning off rust, and then told not to use it because it attracts water and will cause rust. wtf.

Not quite in the same class, but I’m going to shill for Puma work boots. For the anons that need steel toes but don’t want giant fucking brown boots, these Pumas have been by far the best work shoes I have found. The cheap DeWalt and Cat brands you see are comfy, but I only get 3-4 months out of them. Reebok makes some decent ones, but I get about 6mos from them. Pumas are the only ones that are comfy and last me 8-12 months.

Putting in a furnace, it needs PVC tunes for intake and exhaust. Should I integrate a clean out into them?

I want to make a ceiling mounted pull-up bar, something like this picture. I plan to hit it with the grinder and buff it out a bit so it's uniform and clean looking. I don't want to paint it afterwards, because it might serve double duty in the bedroom and I don't want to have paint chips coming down if metal hits it, but I also don't want it to rust. What should I make it out of? My first thought is galvanized, but isn't that carcinogenic? Iron isn't, but it'll rust real quick, right? I could do stainless, but it's expensive as fuck. I dunno. Thoughts?

>How interchangeable is tooling for lathes/mills?

The relevant parts are standardized, and that's assuming you're talking about dedicated R8/CAT/ISO toolholders. You'll never run out of options for tools with a straight shank meant for a collet.

For lathes, the toolholders and toolpost are generally considered a set, but the tools themselves are just plain square shanks or rods (with flats, if you so desire). They'll fit in any toolholder big enough.

Any other tooling (rotary tables, vices, other workholding and jigging, etc.) is, with very limited exception, generic, and should fit any machine that's about the right physical size.

>>1707838
yeah I never use the stuff, so curious how the "correct" way is

Just from the layout and design I would assume it serves to press or crush a pin or rivet in something, some kind of process applying a lot of force between those points but likely not for any kind of wrenching or twisting.

But with manual saw?

if i want to buy a plot of land and build a house on it, where do i even get started? budget isn't an issue, but i lack skills. i can bring people in to help but don't know how to approach this. do i spend the first three years in paperwork hell?

>>1708524
>with manual saw?
no but if you use a manual (hand) saw:
fine tooth or crosscut saw
melamine side up
smooth easy strokes

whichever saw you use the teeth should cut when going into the face (visible surface) of the melamine

>>1708572
Thing is, one side is OK, while other is chipped. I use "universal" saw, which is not good at anything, but does everything. Problem is that this saw works only on push stroke, and I don't know what to do.
Can I score the melamine with a knife and then cut? Or shit will break on both sides?

>>1708576
I didn't realize you had two sides with melamine.
On the top side you are pushing the saw into it won't chip.
On the bottom side where the saw comes out of the melamine, you can make two score lines - one on each side of the kerf (the gap left by the blade).
As you are sawing, the chips will stop at the score line.
If one of the pieces is going to be waste and not saved, just score on the piece you intend to save.
Score a tiny bit away from the saw line because if the saw goes beyond the score it will chip there.
You can do it with a knife but a plastic cutter which has a plowing action works better.

If I want to build a picket fence around my backyard, on the inside of the rock wall that currently encloses it, does that count as building a fence outside the "shared property line"?

Best way to get moss off roof without damaging shingles?

Not sure if this belongs here, but I've got a mouse infestation above the attic in the roof. I can't seal off the entry points since it would require massive investment to take off the roof, replace the insulation etc... so in the mean time until I do that what can I do to contain it? A few traps are lying about but are only occasionally sprung, thinking about those probably scam electromagnetic mouse repellent, what else can I do?

>>1708610
Stack extra layer of wood underneath it when you cut. The wood will splinter instead of the melamine.

Reposting this from /fit/ because I need some help

>need blackout curtains to fall asleep at night
>want sunlight in the morning to help wake me up
Can someone help me figure out how to accomplish this? The only idea I have is to attach a string to some kind of rotating motor which can pull the curtain in in the morning. I would need to program it to turn clockwise a few times at 6 am and then counterclockwise at 6 pm.
I'm a /diy/let and I dont know anything about electronics. Where can I learn how to do this?

I need to make temporary winter greenhouse to protect tropical trees like mango and guava. Last year I used metal posts I pounded into ground then wrapped with 6mm plastic. This year was going to build something with surplus metal like bed frames. Wife suggests using PVC, but I irrationally hate PVC for some reason. I like the idea of metal since I can break it down and store it easier ( but I guess I could do that with PVC too, right? ). I could use some outside opinions.

>>1708849
Weight the curtains so they require pressure to remain closed. Tie string to this then hold string. When you fall asleep you let go of string and curtains slide open.

I want to put up a picket/wood slat fence that starts at the top edge of my (4' tall) rock wall, supported with 2x2" or 4x4" posts sunk into 6-8" dia concrete bases dug maybe 2-3' down. It would only extend a couple of inches out into my backyard at the most but I figure it's a better idea than going through the process of getting 2 neighbors' approval to build onto the shared rock wall separating our property lines, then possibly reinforcing the existing footing for that rock wall just to extend it upwards a couple of feet.

>>1708945
Also I'm asking if it counts as building on the "shared property line" if I'm building on my side/the inside of the rock wall, just 1/4-1/2" away from that wall.

>>1708999
I've been trying to repair the fence between me and my neightbor. They rent the place and the owner never returns my calls. it's annoying as fuck. I'm tempted to rebuild the wall on my property, and paint a giant HILLARY 2024 sign on the side that faces their property.

Anyone own a Heathkit IG-18 signal generator? I just picked one up recently and want some input on what mods I can do to improve performance. I know that there are several, but I do not know how far I should take it.

I have concrete foundation, and shit gets wet in the morning. What should I do? How do I insulate it?

>>1701407
Ok diy I would like a second opinion on this.

Very simple situation, but I'm basically looking for the BEST way to do this.

What is to be done:
>I have an aquarium I want to lay a tile floor in.

Info:
>I will have to joint tiles somewhere in the middle.to complete the length
>The tank is 17.25" wide Inside, but due to nonuniform silicone bevel, tile will have to be 17" give or take with some kind of flexible "outside edge"
>I have no set tile size yet, I'm aiming to use whatever the hell is easiest to get in there.


Main issues:
>having the tiles connect at the bottom to form a near perfect floor without any holes
>with above, have the tiles still be removable for cleaning since keeping 100% of filth from under is impossible.
my current idea:
>run a bead of silicone around the edge of each tile so it has a bit of a form-able edge to fit together well
>run a small amount along the bottom of the tiles to prevent them from sitting directly on the glass and having too much pressure from a single sharp point on the bottom if I put any crap ontop of them.
>have the outside tile edge silicone meet the silicone bevel along the tank and form a seal, and have the edges meet each other to form a seal.

Any input would be appreciated.

I need to make a drying rack of some kind that can house at least 50, say 18x24 sheets of paper. Something like this is nice, but I don't really have a budget. Is there anything I could build that would work to keep that much paper separate to dry?

>>1709497
The only way to make that for cheaper than buying it is by having access to a scrapyard for free and being on welfare that pays you to not work. Use your fucking brain.

>>1709513
I don't necessarily want THAT rack, I just can't see paying over $100 for that. There has to be a way to make something wooden, pvc, or something for less

>>1709515
Assuming you already have a welder, it'd cost at least $40 in wire rod, then you have to bend it by hand in either a bender, or use a torch to heat it up and bend. You'd go through another $40 in gas. I know this is /diy/ but for something like that you're better off buying it, hopefully second hand.

>>1709515
>>1709497
Make a frame out of wood, 2x4’s. Do like an H-shape on the bottom, two posts going straight up.

Get a bunch of wire hangers, drill holes in the wood at an angle so the end of the hangers sticks in firmly. Cut hangers to size, bend them into U-shape, stick ends into holes in wood.

As long as they’re not super heavy large sheets of paper, I bet the hangers would hold the weight.

Sorry, tried reading up on Washington law, but I've never seen anything so convoluted as building codes. Usually I can figure this stuff out myself, but holy fuck...

I live in a post-construction remodeled basement apartment. Noticed a leak yesterday in my bedroom, below the upstairs apartment's front porch. The owner seems to want to pin the damage on my upstairs neighbor, but as best as I can tell, a front porch is an outside area, subject to weather. Isn't it the property owner's responsibility to make sure that outside water can't penetrate into the interior? The place has other problems, like a non-gfci outlet six inches from my bathtub, no vent hood or other ventilation in the kitchen, and I'm pretty sure both units share a water heater because I don't have access to one from my apartment and my shower goes cold when the neighbor runs water, and the front door frame doesn't span the full width of the door. Is this place just a series of building code violations? I really don't want my neighbor getting stuck with the bill over what seems to me like abusive practices by a slum lord prick.

I just poured some concrete in my basement. How long until I can put my washer and dryer on it?

I'm looking for headphones with the following: hearing protection, bluetooth for music, fits under a hard hat.
I know the first two are easy to get in combination. But does anyone know of a brand/model that also fits under a hard hat?

how much weight can a standard wall stud support? could you attach a shelf to 2 or 3 of them that could support a 55 kg dryer?

>>1710789
There aren't exact numbers because there's too many factors to consider, but on a shelf, probably not. Generally speaking, the further from the wall the weight on the shelf is, the greater the force it has on the beam, because the shelf is acting as a fulcrum. You also have to consider these forces on the beams themselves; the closer to the middle of the wall is, the greater the force relative to its stationary points. This is why those shelf supports exists; by distributing the weight from the front of the shelf to a different point on the beam, the total force is distributed across a larger area resulting in more stability.

If I needed to put a 60cmx60cm 55kg object on a shelf, I'd almost certainly build a freestanding 2"x4" shelving unit, and pin it to the wall rather than rely on existing studs taking forces they weren't designed for.

This is all of course assuming you're not asking whether or not it would support your weight from a rope. If that's the case, consider doing something slightly less risky and stupid, like skydiving or random hookups. When I realized I had no interest in living the life I had, I hitchhiked 5000km away from home, resulting in a lot of great experiences that made me see that a life free from other people's expectations was still worth living. Just sayin'.

I have an outdoor fridge that has very important and perishable cultures in it (mycellium and yeast). If it freezes, they will die, and if the tempature is frequently over say 35F, they will grow too much, exhaust their nutrients and die.

Winter is here so I'm not sure what to do. It's just going to keep getting colder. What's the easiest way to set up some sort automated system to turn the fridge on when the outdoor temp is under x (likely around 45-55), and off when it's over x?

Do you think the above will work ok for preserving my fragile cultures? Will the fridge accept this kind of abuse?

>>1711141
Also, since I'll be using the freezer portion too, it'd be ideal if I could wire the freezer to turn on and off at it's own tempature thresholds, seperate from the fridge. Some reommended resources for this kind of stuff would be great.

Surely /diy/ can come up with a more creative way to suicide than hanging

>>1711187
/diy/ certainly could, but a cross-board poster from /r9k/ would be less likely. I know how I'd do it if I still wanted to, but ever since I made changes in my life and outlook, it almost never crosses my mind anymore.

I move a lot because of work. I'm rarely in a place for more than six months. Over time, I naturally drifted towards minimalism.

In the beginning, I would hire movers to help me package up my television, console, games, speakers, entertainment stand, etc. That got old pretty quick, so I bought the best laptop and headphones I could afford at the time, and started streaming and playing PC games. That reduced all that stuff down to a single backpack, and I found I actually preferred it.

Eventually I got my kitchen down to a single plastic container. Just the bare essentials like a pot, skillet, aluminum foil, wood spoon, bowl, plate, a spork, etc. I use a folding knife to cut vegetables and I only eat meat when dining out. I can pack my entire apartment in just a couple of hours. I'm kind of obsessed with getting it down below an hour.

The most time-consuming part is my sleeping arrangement. It takes forever to disassemble my bed and the mattress is heavy as shit. I'd like something I could put away during the day. Something that can be washed regularly, folded, easy to transport to the new location, etc. For example, a sleeping bag on a cot of some kind. But better.

I'm open to any ideas.

Bought these, 1" pipe, and some appropriately sized lags to hold up the pipe flanges. Going to use these to hold a 2 by whatever to the ceiling, and lags to put the flanges on that for a pull-up bar. Would you trust this setup to support my overweight friend? House is all 2x4 construction.

>>1711249
Don't sacrifice your health for the project. If everything else is minimalist, your probably don't need the space below the bed. Just get a mattress that isn't as heavy and put it on a box spring on the floor.

Alternatively, begin wearing only coveralls, and sew D-rings to the shoulders and ends of the legs. Mount anchor points to opposing walls. At night, just hook the D-rings to the anchor points with some rope so your clothing can double as a hammock.

>>1711261
>coveralls, and sew D-rings to the shoulders and ends of the legs ... clothing can double as a hammock.

>>1711249
I slept on a $40 foam mattress topper for two years while in a similar situation. I just picked a spot on the floor for my bed and laid it out. When I needed to move I folded it up and shoved it in the car.
It was intended to be temporary but it was really comfortable so I kept using it. I'm really tall and thin so a 2" piece of foam kept me off the ground, if you're more dense than 6' 150 lb you may need a thicker / more firm topper.
It was kind of fun because when I wasn't sleeping on it I could toss it in a closet, freeing up floor space for activities.

I'm cutting out circles of felt using a 1/4 ton arbor press. ( aint it cute! ). When I use plastic underneath the felt - I have to sink the die into the plastic deep enough to get a clean cut on the felt. It seems like this requires way more pressure than necessary.

So I used 2 layers of felt, and it slices thorugh the first layer very easily - but now I have this shitty felt layer Im chopping through, and gets really messy, inconsistent surface, etc.

What is the proper way to do this? What material should I use under the felt?

Anyone else ever feel like jumping into the washing machine? I can't be the only one, right?

this is a profoundly stupid question, but has anyone ever tried submerging wood in epoxy resin(read: sans hardener) for like, a profoundly long time, and then adding the correct amount of hardener for the resin soaked into the wood, and how well did it go?

I live in alaska, and want to build a guitar that's winterproof.

>>1712193
So you want the wood to be completely impregnated with the epoxy?

How would the hardener ever get all the way in? Seems like the outer coat would start to harden and prevent the inner parts from curing.

Why not try a proof of concept on something smaller than a guitar? Like a ukulele?

>>1712193
Google "transparent wood". This is a thing people do, though from the sounds of things you might want to leave the colour containing stuff in

How well does basic smelting purify aluminum? Is there a simple way to chemically or electrolytically do it for the diy guy? I have a bunch of old aluminum ingots I made long ago a well as new scrap and I figured I'd like to make all of it as pure as possible, take out any silicon or zinc or whatever contaminations might be in there since the scrap was anything from heatsinks to cans to motor/engine castings to wire. Preferably I'd like to do a catchall and try and pull the aluminum from the contamination instead of targeting different things specifically.

What is it the lumber anons always say... something like unless you go with a top tier Stihl, they’re really shitty for the price.

The Echos seem to be the serious /DIY/er’s choice, but if you’re going to upgrade to a good Stihl in the future, why not just grab a Homelite or Ryobi for now?

I learned to weld with a stick welder (as a kid on the farm), but my most common theoretical use-case involves gap filling on thin steel which I think might be better done with a wire feed.

This mosquito zapper doesn't work for shit. I see little fuckers flying in between the gaps. Why do they make the gaps so fucking big? Is there something I can do to resolve this? new metal mesh on there? any requirements for the mesh?

>>1712496
See if you can buy and not just rent the shielding gas in your country. TIG is the most enjoyable and good for thin material.

>>1712507
are you sure they are flying between the gaps, it can often happen the mosquito will have a heart attack but momentm carries it into the bars and the shock restarts the heart and mosquito flies away.

also carefully check the mesh is actually live.

I've lived in a rented flat for about a year now. Over that time the floorboards have progressively more squeaky and will move up and down when you step on them. I'm assuming this is my fault, or do floorboards loosen over time/in the winter? It's pretty annoying for me, I'm sure the person downstairs can hear it but they've never mentioned it. If I mention this to my landlord are they likely to do anything? Do they just lift up the carpets and nail it back down?

I'm considering buying this house and fixing it up. I'm a diy beginner, but I learn quickly and take direction well. The fixes seem like they'd be easy, but I figured I'd ask first.

Do you guys think this sort of house would be easy to fix up?
What changes would you make?

I'm trying to create a very small scale CD.
How would I go about re-creating the opal-esque/rainbow mirror effect that CDs have? Preferably would like to do this with paint. But I'm open to fabricating said CD with a material that exhibits this effect.
That being said; would I just be better off taking an old CD and cutting out a small disk out of it? Or will the effect be warped?

today I bought a davenport desk at a thrift store ($12) but when putting the desk in my car the top compartment opened, got stuck, and split the wood at the hinge screws. is there any way to save this? I'm thinking of possibly completely sealing it with wood glue, even the screw hole, and then just re-screwing it. how fucked am I, and how can I fix this?

>>1712980
I'd remove thehinge, finish breaking off the piece then glue and clamp it back on so you can make sure you have hood coverage. Should be easy to reattach hinge later.

Thanks to borderline rube goldberg circumstances, some paint spilled into my heater. Does this look concerning to you? In my opinion it looks like the dust is more likely to cause a fire, but I really don't know.

I want to make some sensors that triangulate and identify cell phones. I'm guessing with modern encryption techniques this might not be possible?

Just giving you ideas

I wanna build something like this in my room for like $10, doesnt need to look nice.
I want it to hold maybe 10 rims and like 20 tires. needs to be compact as well

individual hooks are like a dollar a piece at homedepot and kinda are too big for just one tire each and too small to hold a couple tires.

I guess they have those bigger hooks that could hold like 3 tires each but im looking to niggerrig a bunch of small hooks or buy like 5 or so thingys that can hold like 5+ tires each

so far im trying to think of something like coathangers (but stiffer) twisted around a 2x4 hung from the ceiling. any ideas?

>>1713371
You haven’t gotten any answers yet? I was going to tell you to just do the goddamn hooks, you can find them in a million different sizes and shapes.

Is it just going to be rims, or like full wheels with spokes and hubs? If just rims and tires, you could probably build some shit like an inverted T with 2x4’s. Otherwise get some piping, either electrical conduit or steel or maybe even PVC ~1” in diameter, and then support it on either ends with hooks or like a couple lengths of 2x4 hanging from the ceiling with a 1” hole drilled in each and slide the ends of the pipe through that. You would have to pull off a couple tires to reach the ones in the middle, but it would be simple.

>>1712567
I don't think the house I'm renting has the amps to run a TIG (40 AMP breaker for the dryer which is the highest in the building) so I'm probably going to go back to the 20th century with oxy-acetylene.

>>1713140
Latex or oil based? Latex will probably just stink for a bit, oil you'll want to get a can of contact cleaner or a jug of denatured alcohol or something and try to wash it out so you don't start a fire. Give it a chance to dry off before firing up the heater obviously

You can obviously measure voltage. You can also get special current probes. Good luck measuring resistance directly.

I've got asbestos floor tiles in my basement, I want to paint over them. I'm not worried about them but they're dark as fuck. I want to eventually remove them and put that epoxy floor coating down but it's not in the budget. Any ideas better than a layer of kilz and whatever latex paint is cheap and will peel if I walk on it wrong? Keyword is cheap, I only use it as a shop area right now.

I have a Trane XR80 furnace/heater and it wont blow hot air. I have the gas valve in the on position, the gas ignitor/injector/whatever inside the furnace proper switched to the "on" position and I went so far as to clean the carbon buildup off of the flame sensor.

Should I just nut up and call the service tech? I'm only doing this to attempt to be more familiar with my houses hardware and save $60-70.

>>1713965
Does the hot surface ignitor glow during the call for heat? Are you getting any trouble codes? Do you hear the gas valve open up?

>>1713968
>Does the hot surface ignitor glow during the call for heat?
Yes
>Are you getting any trouble codes?
The little red indicator light blinks twice intermittently after the blower actually emits air, supposedly that's a "system lockout" code where after 5-6 attempts at successful ignition, the system locks itself out and just blows cold/not-hot air.
>Do you hear the gas valve open up?
I dont know what to listen for, so I guess not? I have a little valve (broke my camera on the jobsite so a pic isnt going to be very good) that comes out of a tee (the tee splits the gas line to feed the water heater & furnace) before it hits a red gas valve and the red valve goes to the furnace. It's a brass valve with a flat knob that has a hole through the knob. Should I turn this one or leave it alone? Right now the knob of that brass valve is running in-line parallel with the tee and pipe.

>>1713980
The valve I'm talking about is electronically controlled and is in the furnace itself. If it's working properly after the ignitor is glowing you'll hear it click and you'll hear the gas begin to come out. If you're ignitor comes on and you don't get a flame it's likely not opening(or you don't actually have gas running to it). Could be a few different issues. Do you have a flow diagram inside your service panel? They usually have a switch on the valve itself, make sure it's in the on position. Check connections running to the valve and a few of the safety lockouts. If you don't have a multimeter or don't know how to use one this will get very tedious very fast. Keep in mind that there is 110 volts going through various parts of the furnace, if you contact a hot point you will shock yourself(hopefully you're not touching something grounded, like the furnace)

>>1713980
both of these valves are in the ON position

>>1714012
>>1713986

>>1713980
What model furnace do you have? Pay closer attention to the blinking light, does it have a short/long blink speed?

>>1713986
>They usually have a switch on the valve itself, make sure it's in the on position.
I have switched it to on, as per both of these pics:
>>1714012
>>1714031

I do know how to use a multimeter but it's a lil cheapo Harbor Freight meter so it doesn't have an anmeter.


>>1714033
Trane XR80. It blinks steadily/rapidly up until I attempt to turn the furnace on; then it attempts to ignite for about 5-6 times, then goes into "lockout mode" where it just blows cold/room-temp air and the indicator light blinks twice at a regular frequency.

>>1714049
Neither of the valves in your pic are the one I'm talking about. See >>1714031. It won't look exactly like that one but it'll be on the pipe leading down to the ignitor and flame sensor. You don't need to check amperage, just resistance/continuity, 110vac and 24vdc

>>1714062
I turned that one to the "on" position too, as per the instructions on the furnace cover. I will check that one for voltage and ohms though

I found some extension cords in my attic they've been up there at least 15 years if not more. Are they safe to use or should I just throw them out?

>>1714071
Yeah, you've got a couple things you can check. If it's not getting voltage their could be something preventing the board from powering it. Normally you should get voltage to it 5-10 seconds after the ignitor starts glowing.

Weird question but was your gas shut off recently? If so you could potentially have an air gap in the pipe so even if the valve is functioning properly it won't light. You should be able to hear it, first click for the relay for the ignitor, 2nd click will be for the valve.

>>1714073
Visually inspect them for cracks, cuts, dry rot, hillbilly repairs, anything off. Should be fine if the wire coverings in the sleeve aren't damaged but if you're concerned don't use them unattended. I know I wouldn't with an unfamiliar one but I've got cords as old as me that are just fine. they've been stored and maintained properly though.

>>1714049
When you say turn on, is that from the thermostat or the wall switch? Try power cycling it and observe what happens in startup.

cheap way to store nystyle thin crust garbage pizza:
make a sandwich of two slices with a triangle of wax paper in the middle
and if the slices arent giagantic huge, u can fit both of them in one long strench of foil folded over itself
stack the foil/waxpaperPizzaSandwiches on each other so they freeze compact
i wrap a couple at a time in 2gal freezer bags that i reuse, but i suppose u can just use two regular bags over to reduce moist or unmoist airflow creeping in there or something.
i then take out two at a time and leave to thaw in fridge in a plastic bag and eat them both within a day or three.
to cook, i place in toaster over for 7minutes on full blast with a small piece of foil capped over the cheese, so the crust cooks at full blast and the cheese at half blast
after 7 minutes both the chese and crust are perfectly crisp :drool:

wrong thread

...but i need to mention that you put wax paper to cheese

and you need to let the fridge slices that so they arent frozen to the wax paper, or worse one slice frozen to the other

you need to let the fridge slices thaw*

I saw some dude with a double ended wrench where the ends were 90 degrees offset. Presumably so it's more comfortable to apply force. Is this a total meme tool or actually worth it? I have to travel with my tools so I feel like they'd be hard to pack.

Looking for a cheap oscilloscope to test amplifiers and observe the waveforms for clipping. Mostly car audio amps.

>>1714273
They're for places you can't get a traditional 300 combo wrench to turn you fucking troglodyte, not to "make it more comfortable"

If you've never had a use for it then it probably won't be useful for you. Also "double ended" doesn't tell us anything.

I want to get into machining as a hobby, for a variety of reasons that aren't particularly important, but I'm not quite sure where to start. It doesn't seem wise to just drop a could grand on mills and lathes and shit when I don't even know what I'm doing with them. Any advice? Perhaps some cheaper hand tools to start with? Some projects for beginners? Good learning resources?

If you can see the clipping on an old CRT scope it's already pretty bad (>1%). With a DSOs it might be possible to use the FFT. Easier would be a soundcard to generate and analyze the signals. For the output you should use an attenuator of course.

>>1707223

I've got an outdoor shed in agricultural zone 8a, DOE (department of energy) zone 4, that I'm trying to grow mushrooms in commercially. Right now I'm struggling with figuring out what kind of insulation I need to put up, and how to do it. I bought some foam board panels, but the R-value is only 7.8, and it looks like I'll want an R-value of around 20 on the walls, and 30 on the cieling / attic, so what I bought is WAY short of the target R-value. The dimensions of the shed are approx (LxWxH) 14x10x8. I'd like to do this on the cheap also, ofc.

What would you suggest I do?

Has scrap magnesium always been worthless? I was given about a hundred pounds of more or less pure magnesium from work (yes really, given. Not stolen, given. Like verbally told by my boss's boss's boss "yes you can take that magnesium home if you want, it's scrap to us now it'll just go in the recycling bin"), and I've called for local recycling places and none of them take it, one even said there's no market for it so they don't bother. I always thought it was mildly valuable kind of like aluminum because stuff made from it is usually much more expensive than comparable metals/alloys. Or is it just more expensive with massive margins because that's what each markets target audience is willing to pay?

>>1714666
Stack them 2-3 thick.

>>1714614
Really? I was just gonna feed the amp sine wave tracks and use the scope to determine the maximum gain I can achieve without clipping.

Get one of those Chinese $25 kits you see all over Amazon. There’s a bunch of different options but it’s the same internals with different plastic cases and that seems to be the main use for them.

>>1714732
Had the dso brasnd of one of those. Not exactly a rigol but for 35 bucks it's great for simple things like what you're doing. Plus you can power it with a diy lithium or alkaline battery pack so it's truly portable. I would make sure to get some longer leads though because the ones with comes with are like 6 inchs total length, worthless. I got 2 that were either 24 or 30 inches (I forget it's been a while) and one has alligators and the other has hooks. Cost maybe $12 for both.

>>1714704
you are talking like MGO boards, not PURE magnesium right?

>>1714737
not op, but that's pretty cool. never thought to pick one up.

>>1714737
What did you use it for?

I want to start fucking with scopes and was trying to look for something <$100 just to learn, but those didn’t seem to be much good for anything besides setting the gain on subs.

>>1714738
No, ~50lb magnesium anodes. Not sure what kind of alloy annodes usually are, but they're for sure magnesium since it says so right on the bag.
When they are built and shipped they're inside cotton bags filled with clay and silica with a wire coming out that you attach to the piping or whatever. When a pallet was being unloaded two of them fell off the top and ripped open on the ground, making them unusable. And as I said the third-degree boss man said chuck em or take em, my choice.

>>1714740
Just basic bitch shit, checking frequencies, looking at ripple, watching voltage changes too fast for my multimeter, ect. Simple shit nothing crazy. If you want a scope for actual real engineering and debugging, I would say pony up and buy something half decent so you know it will be consistent and trustable and reliable. If you still need a basic totally portable scope you don't mind getting lost stolen or broken then by all means still get this one but don't expect to be able to do like NSA computer forensics with it.

>>1714751
I would have bought the $350 Rigol last spring if I didn’t have a GF with a birthday. Main reason is to see the spikes the meter can’t catch, but I don’t want to spend $150-$200 and then as soon as I learn how to use it, end up needing the $400-$500 model for what I want.

Maybe I will get the cheap ass one eventually, or stumble on a cheap used one somewhere.

What ever happened to anon from a few weeks ago who “found” all those scopes at his college?

Hi /diy/
I have a white Ikea galant desk like picrelated. The desk top has some minor damage and stains on it. I think the desktop is some kind of particle wood (but its quite heavy). I'm not sure what the top and edge material is, might be some kind of laminate.

Anyways, I would like to make it look nicer. I don't think painting it will work since I'd have to remove the laminate, etc. I was thinking about vinyl wraps. Is this a stupid idea? I know absolutely zero about them, including how expensive it is. I see vinyl wrap videos on cars and I figure it should be really easy to do a table top. Would appreciate any advice.

Anyone know what engine this is? This piece of shit needs a new carb, and Briggs and Stratton in the 80's were a bunch of sister fisting retards who designed an engine that you need to pull the fucking head bolts to take the cover off to get to the carb, and I want to have a head gasket and bolts handy before I go fucking with that.

I looked for a model number on the engine, but the only place I can find one is on the top, and nearly illegible.

So what does it say?

I can make out the word "model" and about 8 numbers in a few places. Not the entire thing, or even chunks of it.
