/diy/ - Do It Yourself

what are the odds of anything going wrong while I cut plastic with this heated scalpel? the blade itself has been previously heated with a lighter and candle with both being inadequate heat sources. I don't want my ass zapped to oblivion.

googled it, tried it, worked. welp, I should have been smarter to google it first.

How do I fix this?

What's the most effective way of distributing air as evenly as possible over an area?

>>2448721
looks like it's penetrated the finish, that's a sand back and refinish job unforch

>>2448797
You need to feed the air into a plenum chamber, with the exit fitted with a diffuser or louvre.

You will need a high flow rate from the inlet hose to ensure there's enough pressure in the chamber to force the air out evenly.

If the air flow is low, then shape the chamber so the outlet side is smaller than the chamber itself. This will accelerate the air leaving the chamber and allow the diffuser to work properly.

This is a stupid question that doesn't deserve it's own thread but is related to coasters.
I've always seen coasters on tv and they claim to be important. But besides this moldy post, I have never once needed a coaster because glasses never seem to ruin any furniture I set them on.
Did wood finishes change in the 90s to make coasters obsolete?

how easy is it to replace a motherboard on a smart tv? i would just have to reconnect all the components, right? no need for soldering or anything?

>>2448803
Poly finishes are more common, which resist water stains a lot better, so coasters have fallen out of fashion. But heat is another consideration, like hot coffee or tea. I use coasters because I drink large glasses of ic water through the day, and they capture the condensation from the glass, and I don't like pools of water on my desk. (which has a poly finish).
Water stains are an issue with laquer/shellac and wax.

>>2448721
Remove the finish around the stained area, use oxalic acid to bleach the wood back, then refnish. It would be better to refinish the whole top, as blending finish can be tricky.
Do not sand the whole top, like that other monkeyman poster said. That's the cheap, stupid thing to do. You need to bleach the stain out, and at most remove the existing finish with paint stripper, and refinish the whole thing - and use a good poly to seal it so your non-coaster using ass won't fuck it up again.
There's tons of videos online showing how to use oxalic acid to remove water stains. Watch them. You can fuck it up even more making too strong a concentration. Luckily it's pretty light wood, so it'll be easier. Thomas Johnson on YT uses it all the time for this exact purpose, or watch this:

I got a laser printer and no matter what, on every page, no matter the color used, this defect is in the same exact spot every time. I thought I cleaned everything, but apparently not. Where should I look for this piece of debris? It's an HP laserjet 4550. It works well for the most part (especially since it was free), but this constant printer nipple is getting annoying.

thanks, desu

>>2448360
get your fucking shit together faggot. we already have sqt.

>>2449062
Asswipe, a stain like that could require taking a shit ton of wood off, when you can do what I said:
BLEACH the stain, refinish. Funny how you left that crucial part out, because you're asschapped from being called a monkeyman.

Found a gopro underwater at 30 feet depth, it was underwater for almost 2 months.

The SD card is working.
I've cleaned it inside out with alcohol-like solution and let it dry well.

I've tried charging it but it won't turn on or appear to even charge at all.

Should I risk putting my gopro battery in it to test or will it fuck my battery? Is the gopro that I found beyond restoring?

If lightning strikes my off grid house (wood framing, metal siding+roof) will the wires I have in my walls be damaged?

Im building a small offgrid house in the middle of a very flat desert. I am worried my solar panels or antenna may be struck by lightning. In this situation, would the power surge damage the insulation to the wires in the walls? I would rather run the wires in exposed conduit if there is a chance Ill need to tear the walls off to evaluate the wires.

What's a good textbook for learning how to design a house under the International Residential Code? Or should an aspiring house designer just eschew textbooks and read the IRC raw?

I need to replace something in my stove. Is a pressure regulator and safety valve one in the same or do I need two separate parts? Any time I do a search for safety valves just the pressure regulators come up.

Okay anons, I moved into my apartment back in November, and I used the stove top once but it was making concerning noises, and I was sweating the whole time while cooking my food, I mainly use the stove, but would like to have the stove top available,

I've got one:
Chacoal cooler relies on evaporation to be effective, since the whole process is based on the water evaporating from hygroscopic charcoal.
However, since I'm clueless on the subject, I need to know about two conflicting (at least for me) factors
On one hand, you've got best evaporation when you put it directly on sun, and be black (not an issue, given that's the color of charcoal), for minimum albedo. On the other, to keep things cool, you should keep them under shade and preferably white, for maximum albedo.
So what's in the end better for a charcoal cooler: to have it's walls exposed, and thus evaporating faster OR to have it under shade/painted white to not heat up the whole box?

my electrical ground is stuck in the ground where my house trap sits, but it's also grounded on the water main. do I actually need it to be stuck in the ground or can I remove it so I can cover the pit?

You need it. It's grounding the water pipe, it's not grounding the house.

hello im trying to mount a folding basket on the front of my bike for really cheap
i need something to hold the basket away from my front brake tho its just dangling off my fork by the hooks that came on it
i have zip ties but whats something cheap and sturdy a few inches long with a hole either end for the zip ties?
i tried going into a hardware store and couldnt find anything that looked useful

>>2452022
isn't the water pipe already grounded because it's in the ground?

this is my shower valve. I need to replace it, but I don't know what to search for or what type it is since it seems non-standard.
There is a knob in the front that controls water flow, and an additional knob in the back that controls temperature. They are co-axial.
Can I just replace it with any old shower handle or does it need to be a similar form factor or mode of operation?

>>2452139
No. It's stuck in the earth. Thats not actually an effective path for current return for an electric fault. With the wire its part of your house's electric system. With the wire it can trip a fault in a timely manner.

For example, the difference between two groundrods set is like 20k ohms.

If it's completely floating in your house, it will never trip a breaker unless it's gfci

How do I fit these 2 freezers under this table?

Freezer specs recommend 5" of space on back and sides, but when I fit 2 under the table they only have 3" of back clearance and 1.25" of clearance on sides. Would they be fine since the front and top is so open?

Since they're small chest freezers i figure the compressors wont run too often, so the little hot air they do blow out will disperse pretty easily.

What if I rigged a switch to the outlet so when the compressor(s) turned on a fan would circulate air around them? Id rather avoid this if necessary.

Polycarbonate or PVC for roofing material of a backyard conservatory? I live in Australia so it has to be pretty UV/heat resistant.

what would be the best way to make a desk like pic related, that runs the length of a wall? how should I support it? there has to be something less obstructing than those weird angled pipes they used here. would shelf brackets work? for the tabletop itself I'm planning on using something like this because it's cheap and I'll probably just paint over it https://www.lowes.com/pd/ReliaBilt-21-32-in-x-16-in-x-8-ft-Square-Unfinished-Spruce-Pine-Fir-Board/5002124699

I don't want to drop 250$ in wood to redo my shed door entirely.

Nevermind. I had to clamp the compression nut snd unscrew the valve from it.

is this what's making my shower whistle?

I've got a carport like this except it has a roller door on the front and it's on a slab. I want to enclose it, but I'm not sure the best way to go about doing so. If I brick up the side I'm worried the wall will just collapse, and I've only done a bit of brick work before so I'm not sure I'd be able to build it perfectly. Additionally id have to put a window in and all that.
I'm pretty good with woodword and would be confident in framing, although I'm not sure the safest way to mount a frame to brick, especially because I live in an area where 50+ mph winds are common so the frame would have to be built pretty well.
Thoughts on what to do? I like the idea of a wooden frame since it's easy to do but I worry it will rip out the pylons if it gets to windy

The underside of my laminate countertops is a little flaky. Should I do anything to shore it up? Hit it with kilz or something?

What does a ground wire actually do? Can you get shocked by it? Assuming it's wired properly.

>>2453046
It's there to provide a safe path for current in the event that something else isn't wired properly or breaks. Under normal circumstances the ground wire should not carry current. Picture an appliance, like a washing machine, that develops a short inside causing the chassis to become energized. If you have no grounding wire and you touch it the current can find a path to ground through you. With a grounding wire present, it will take that path instead. It's like a harness when climbing, it has no function until it does.

where can I get decorative fasteners? I need some to be weldable
like this but handmade looking, it doesn't need threads
I'm going to be selling what I use them in so I need a lot of them and don't want to make them myself

Reposting cause I posted it in the woodworking general without checking the catalog for a thread like this first like a retard.

Looking to start doing some simple woodworking with the eventual goal of hopefully making some custom furniture for my house and shit. I'm currently looking into table saws, specifically what I can find cheap secondhand on places like fb marketplace. I've been keeping an eye on listings in my area and see plenty going up all the time ranging from $50ish dollars up into the $300 range and was hoping to get some advice on what to look out for to get the best bang for my buck.

Are there any particular brands that are more worth it at the price point or things I should stay away from? I know all of them are going to be pretty barebones and no frills but I'm fine with that.

Most of the ones I see are craftsman or skil, with the occasional newer looking Ryobi or rigid that I'm assuming someone impulse bought after watching a bunch of YouTube vids and realized they were never going to use. Is it worth shelling out the extra hundred or so bucks to take advantage of some idiot trying to recoup their money and grab one of ryobis for $150-$200 or should I just grab whatever the least abused looking sub-$100 craftsman shitter I can find is?

Ideally I'm hoping to be able to do a fair amount of modding/improvement as I learn by building or upgrading the stand, extension tables, etc, not sure if any particular brand tends to be better suited to that kind of thing or not, so feel free to call me a retard and teach me shit I should probably already know.

You want a minimum 13 amp saw that can cut at least 24"

If you hit these marks, your saw blade choice is the only thing that matters.

The issue with used saws is the bearings can go out. I have a circular that I've beat the shit out of (Wen, 13.5amp), cut landscape block, concrete and all kinds of shit I wasn't supposed to. It works fine but the bearings are finally going out of it despite everything else being 100%

Start a used saw up before buying and listen for 2 distinct WURRS
One is the motor, the other would be bad bearings

With table saws, your up and down mechanism can go bad and you can break your miter lock. You can also bend the table (obv) and the fence lock mechanism can go bad as well

I would honestly just buy the cheapest off brand saw that's at least 13amps and that can rip 24inches and call it good.

I've owned a Bosch and a DeWalt and they both have their own shit that goes bad. Buying cheap new is what you need to do your first time to really get it

Are there any cheaper sources of leather than what im finding online?

Thanks frens.

There is either something stuck to your cyan drum or developer unit, it might be combined into the same thing. Spin it slowly by hand and look for something. You'll probably just have to buy a new one. I'm assuming you are using a color laser.

Basically a gas torch with several tips, including soldering iron, scalpel and rounded heat shield for heatshrinks. Not too expensive either, paid 40 eurobucks.

What would be the drawbacks of apower generation turbine running on liquefied gas like Propane or LPG?
Pros:
-Compact fuel tank (fuel can be stored at high pressure)
-No compression stage needed, therefore no compression losses

Cons:
-lower energy density:
-propane: 25MJ/kg
-diesel: 38MJ/kg
-gasoline: 35MJ/kg
Propane is cheaper though (at least for now) and whereas 15 bucks give you 11kg of propane, you only get 8-9 litres of gasoline/diesel, so it's +/-0

>>2448360
Question about insulation.

If I made a house out of Aircrete, would it be better to make the foundation/base/floor out of concrete?

I'm choosing aircrete for the insulation because normal concrete lets heat and cold flow right through it. But if I put the base in the ground as concrete would it actually help insulate the house better by absorbing the temperature from the ground and passing it through to the house? Or should I just make it all out of aircrete for better insulation?

>>2453567
Limecrete

>>2453582
Limecrete in place of Aircrete house structure or in place of Concrete base?

Should I sand floors or paint walls first?

>Did wood finishes change in the 90s to make coasters obsolete?

95% of furniture you buy in a store is lacquered. In my opinion, lacquer is the one of the least desirable finishes out there for something you're going to interact with daily. Maybe for a coffee table or something without soul its fine. It takes very basic gear to apply, you can apply it super thin so you can stretch your supplies a long way, and it dries incredibly fast. Cookie cutter manufacturers love it for these reasons. The look and the feel is worse than polyurethane or polyacrylic, which I'm also not a fan of. Typically fine furniture has an oil finish or hard wax finish. Sometimes you see something like shellac but that's becoming more uncommon. Oil finishes soak into the wood and are supposed to prevent water from soaking into the pores for stabilization reasons (humidity) but also to prevent water damage from spills. BLO is less good at this but tung works fairly well. Since they soak into the wood you don't lose the natural warmth and feel of bare wood. With lacquer you just feel the plastic finish that's left on top the wood. Seems like a waste on something nice.

If I got a cement floor, what's the method called of making the floor look like this?

>>2448992
>Water stains are an issue with laquer/shellac and wax.

Lacquer, if applied correctly, doesn't have issues with water unless you submerge it or something ridiculous. Shellac, hardwax, and oil finishes can have water issues. They're certainly more sensitive to it than lacquer or urethanes.

>>2448995
>Do not sand the whole top, like that other monkeyman poster said. That's the cheap, stupid thing to do.

Yes. Terrible idea since it could very well be laminated and OP would sand through the laminate trying to get to fresh wood.

>>2453598
Well yes but which one first

>>2453617
Tiling?

>>2453630
Is that tiling? I thought it was cement made to look like tiles.

>>2453630
Nevermind I figured it out. It's called concrete stamping.

>>2452592

Get an abrasive blaster and a bag of abrasive. They look like this.
https://www.harborfreight.com/air-tools-compressors/air-tools/blasting-cleaning/20-lb-pressurized-abrasive-blaster-68994.html

Take the doors off the hinges, blast them to remove the paint and the rotten wood. Fill whatever hole or dimples are left with bondo or your choice of filler. Repaint. It'll probably cost you about $100 but you end up with a new tool out of it and your next fix will be much cheaper.

>>2453614
Aggregate adds strength, just like in concrete.

>>2453585
For the foundation

>>2453671
I heard it's way more expensive and takes months for limecrete to dry and the advantages aren't worth it.

Is this true?

>>2453671
Actually I've decided I'm going with Aircrete for everything. I plan on dropping weights on the floor and aircrete has better shock absorption.

hooking up 2 VFDs to the same 1 phase dryer plug
they go in parallel, not series right? do they need anything between them and the wire from the plug? just a sanity check cause i did this already and blew one of them up

>>2453673
Both true, but it overall will last a lot longer, far better Insulation than concrete, and it's breathable too, less likely to crack. Better made with care than done fast and nasty

>>2452592
I'd start over. They aren't well made to begin with, and they're warped and rotted. Rebuilding would be as much work, you'll have to dissassemble anyway.

>>2453456
Overcomplicated solutions are the bread and butter of /diy. What did you expect on 4chan, reasonable replies?

I moved into a new apartment this month and once every few days I'll find a cockroach in the kitchen near the sink. I've been incredibly clean with no food out, and it's always one or two. I think they are scouts. Yesterday I tried to kill one and it ran into the crack under the molding, making me think this is where they have always been coming from. You can see how it comes up slightly on the right side. There is an elevator shaft behind this wall. I figure if I can seal any holes in the wall then that should stop them permanently. But I'm a renter and the owners would almost certainly have a problem with me tearing out their dogshit work.

What's the solution here? Is there some kind of expanding foam spray I can squirt in there that will seal up the crack? I know this moulding is literally just a tube and the hole could actually be anywhere along the entire wall. Maybe if this hole were sealed they would start coming out around the sides of the floor cabinetry. I looked underneath the sink to check for holes and although I couldn't be sure I think it would be best to put something around all the pipes anyway. Like some kind of putty.

What should I do? Thanks. The owners suggested buying roach traps and being cleaner.

here is underneath the sink. I will probably have to seal that gap between the sink cabinet and the wall. I dunno.

/mu/ was no help so I'll post here.
I've been repainting my bass, I have a full color coat on it and have knocked down sputters and lint/dust spots and now have a spotty slightly shiny matte, that is not very smooth, not glossy, but completely uniform color. Do I need to sand down the color layer any more before I apply the lacquer? I want a glossy finish in the end I know I need to wetsand and buff the outer lacquer but idk about the color layer itself.

If I want to plug up some screw holes in a textured wall, I should just get some spackle, put a dab on and run a squeegee over it? Is this a reasonable/valid fix?

I want to take wild weeds and shred them up so I can either compost them or feed them to my birds. I feel like this isn't a job that should require a powerful engine so I want to build a hand crank mulcher as cheap as possible. I have access to a 3D printer and I'm thinking of using a wooden dowel for a drive shaft, can anyone think of anything that could go wrong with this?

>>2453729
Silicone caulk. Also take loads of pictures of this crap and the bugs around and be prepared to file suit if they complain about it when you move out.

>>2453752
Yes but unless it's exactly the same color as the rest of the wall you'll want to paint over it again.

I'm trying to bleed my master cylinder in my vehicle, with clear tubes going from the ports to the top

Fuck man, is there an easier short term option? Like just spraying bug spray in there? or Vinegar and Lemon or some shit like that?

>>2453760
752 here, thanks anon :) my walls are an off-white, so I'll try and find some offwhite spackle(?), or go rummaging through the gayrog before giving up and buying paint. Cheers

>>2453762
Usually not if cylinder is new or freshly overhauled. I bleed them briefly then connect the hard lines (using anti-seize on all threaded connections and on the caliper bleed nipples which also helps seal threads during bleeding) and finish bleed conventionally or sometimes with a hand pump.

Finishing my basement:
whats the difference between subfloor and underlayment for flooring? is it necessary for luxury vinyl flooring over a concrete floor?

>>2453995
The subfloor is the structural floor layer, underlayments would be anything installed over the subfloor to create proper conditions for the finished floor. For example cement board would be an underlayment and is typically installed over plywood for ceramic tile since it would crack if you installed the tiles right over the plywood. A lot of floating vinyl planks require a moisture vapor barrier over concrete or you will void your warranty if you don't use one.

>>2454011
so my floor right now is just filled cement. Does that count as a subfloor?
Is a moisture vapor barrier (I assume this is just like a plastic sheet for drywall) enough for vinyl planks over concrete?

>>2454018
Most of them say to use 6 mil poly over concrete

>>2454026
thanks. I'm assuming there are some vinyl floorings that don't require any kind of underlay and can be placed directly onto the concrete slab?

>>2454068
There are some that come backed with underlayment material already from the manufacturer, not sure whether they're worth a fuck though

>>2453995

You'll have a smooth spot doing it that way. For a small hole, should be fine, but if it's obvious, you gotta do it right. Textured walls are sprayed - you can buy can of it, that's what I use. I have a can of Homax that's lasted years for small repairs from holes. Practice a bit first - you have to spray, match the blob size, let it set, then knock the top off. It's easy once you get used to using it.

Can I realistically solder a bigger battery to this bad boy without by house burning down at some point?

Provided battery placement is not a constraint, and I can get my hands on a battery with the same voltage?

Heyo /diy/. Been thinking about getting into leatherworking as a hobby and I'm starting from scratch. Are there any good resources for starting out, and what kinds of tools should I get to begin with? Mostly thinking of making dice bags, maybe branch out into knife sheaths or simple wallets.

My home is humid.
Like, water dripping from your nose and walls growing mold if you don't have the windows wide open 24/7.
What do?
>Inb4 Bitch, I burned alive this summer, I'm gonna freeze to death again this winter, I can barely afford warm water and things are only gonna get worse.

As a guy with a desk job who's rarely done anything construction related, how hard would it be to build my own small house? I probably wouldn't do my own electrical because I don't wanna die

>>2454377
You know what the funny part is? Electrical is probably the easiest thing you can DIY on your house.
It's foundation, structuring and roofing that scares the shit out of me.

>>2454378
Its not retard. Lot easier to make a 90 degree corner than fuck up a split phase voltage plug. Morons like you have never ever worked with elektra.

>>2454377
What kind of house are we talking about? If we're talking something super basic, four walls and a roof, you probably can do it.
You'll probably get assraped by bureaucrats, though.

>>2454387
I don't know how things are in your local shithole, but in mine everything is written in black and white in the norms. If you know basic math and have a middle school grasp of how electricity work you can just learn the norms, do your own electrical plan, measure everything, solve a few equations, check a bunch of tables, buy your equipment according to your calculations, do the manual work and then test everything to see is all working accordingly.
Just make sure you understand every aspect of what are doing and don't rely on guesswork: follow the norm. You don't need expensive equipment, if you are deathly afraid of electricity just use proper PPE.
I have redone many of works of so called professionals and never had any problems with it.
>Morons like you have never ever worked with elektra.
Cope. If it were up to me, all electricians would have to search for a new job.

>>2454252
Yes. Those are all Li-po 3.7V batteries. Aliexpress has just about every size imaginable and they usually perform okay. Each of them tends to have its own protection board in the part with the orange tape, yours looks like it has one, too, so you can theoretically even put them in parallel without significant danger, but it's probably best to just use a single larger battery.

>>2454387
Done properly, you will never even be close to touching a live wire

My dad bought a "Roomba" for like €1400 as a "moving in gift", but the smartass forgot I have a heightened section in my main floor so it can't access the main portion of that floor.

What is a non-idiotic and "aesthetically matching" way of solving this? If I were living alone I'd just throw some cardboard on the stairs to solve the problem, but my wife demands "muh aesthetic"

Pic related to see the stairs/height difference.

>>2454876
Buy a $120 Xiaomi vacuum for the easier zone, put the 1400 one into the bigger/more complicated zone. Or sell the 1400 one and buy two $500 Xiaomi's.

It's a "Roborock S7 MaxV Ultra" as a reference.

Would 2x "Roborock S7+ w/ emptying station" work?

>>2454881
Well you have to decide what features are important for you. These very expensive ones tend to have vacuum container emptying and water replacement for the mop as well as a cleaning unit for the mopping heads. The same ones' cheaper variants like the base S7 don't have the mop cleaning. In my experience, though I only have the cheapest $120 model, mopping isn't such an important feature because these robots scrub the floor of dust anyway, so the mopping is only really for stains and mud, which they don't remove that well. It's still good to have the capability of mopping, but the mop self-cleaning and water resupply is probably overkill. The regular emptying station for vacuuming would be useful, but you still have to clean the filters every 2-3 weeks on the robot itself if you don't want it to stop sucking.
Once you go into sub-$300 models, they tend to have less fancy navigation, they might get stuck more often, but it's not an absolute rule.
With all that said, S7 is probably okay. I'd maybe spend some time digging around for navigation and suction reviews, but Roborock tends to do well enough on both. Navigation is the most important feature, as that decides whether the robot gets stuck on shit or not, and whether it knocks over your lamps.

>>2454876
The old room as came with like little IR boxes that you could put on the floor to make an IR “wall” that the room a wouldn’t cross

>moving into a mobile home
>all the walls are wood paneling
>some of the walls in one bedroom have damage
>layers of wood peeling, deep gouges, areas where the seams have split and the walls are even pushed in a little, etc
>don't want to pull the paneling off to replace because I know I'll just be opening a can of worms

How bad of an idea would it be to just go over the existing walls with new bead board? I'd attach it with liquid nails over the whole panel and a bunch of 18 gauge nails on the studs. Then new molding around the ceiling and floor so there's no visible gaps.

I want to put peel and stick planks in my living room. Should i start laying them down along the wall? Or should i start from the middle of the room outward?

>>2454967
If it were me I would either ignore it or else fix it correctly by removing the damaged panels, inspecting for moisture or other problems and then installing new panels (or preferably drywall) In my area, I had a hard time finding beadboard panels for anything close to the price of drywall, although of course they are much less labor intensive to install.

This super cheap and thin "wood paneling" that they use can often turn super wavy and go completely to shit from minor moisture problems (even from just high humidity and temperature cycles I believe)

If by "opening a can of worms" you mean that you will discover moisture intrusion problems, then you probably should open it up if you intend to extend the lifespan of the structure by fixing this. The reason most of these things fall apart and become dilapidated is because people keep deferring necessary repairs and maintenance.

Does electric polarity matter with an air compressor? I need to replace the power cord on something my granddad "made" and I know dick-all about wiring.

How do I make a jumper cable for my 24v 100a battery, to connect it to the inverter? No companies make those locally or sell only two pieces of them. I'd imagine I'd need some 2-3 AWG cable, and them come M8 terminals, how the fuck do I crimp them? I ain't buying a crimper just for this fucking job.

>>2455032

Assuming US/NA electric: From a "will it work" standpoint, no. From an electrical safety standpoint, probably yes.

If the switch only disconnects one wire when it's shut off (99% chance it does), that needs to be the live/hot wire.

>>2455048
Crimps are for suckers

>>2455049
Are there any clues I can look for to know which is which?

The motor doesn't run unless it's plugged in, just as a note. So of course I only plug it in when I need it. The current plug doesn't even have the larger prong to key it. I'm guessing that it won't actually matter as long as I continue using it in that matter.

>>2455048
You can use a mechanical lug terminal. They're cheap and effective, and you can get them rated for flex wire that is common in installs like yours.

Alternatively, If you have a torch, you can use solder pellets. They are a small, individually sized block of solder and flux that is placed into the lug and then heated with a torch or flame. Once molten, you insert the stripped end of the wire and wait a few seconds for it to solidify.

They make pretty decent connections and they are cheap and easy to use if you don't want to use a crimper or a mechanical lug

>>2455094
and here's a pic of the solder pellets along with their lugs.

>>2455048
there are ebay seller that make them to order out of battery or welding cable.

>>2454979
To balance the planks and avoid small cuts find the center point of the room and snap a chalk line or dry lay some planks and draw a line along the edge. Take your wall to center point measurement and divide it by the plank width. If that measurement shows you will have less than half a plank width cuts at the walls you should adjust the center point over by half a plank.

For example if the width on one end of the room is 13'6" and the other end is 13'5-3/4" you would measure out 6'9" on one end and 6'8-7/8" on the other end and snap a chalk line. Say your plank is 4" width you would take 6'9" or 81" and divide by 4" equals 20.25 planks. You don't want to have 1" pieces of plank along a wall which is 0.25 of a 4" plank so you shift your center line over by half a plank width (2") so now you would have 3" pieces along the walls instead of 1"

is the reason of doing something on DIY because it's cheaper than paying some "professional" to do it?

>>2455131
Nope, because in most cases its not actually cheaper.

any advice for diagnosing and fixing a malfunctioning kitchen garbage disposal? It just hums when I turn it on, like it's jammed, but there's no silverware stuck in it. It looked super rusty. My landlord is gay and retarded and doesn't respond to my maintenance requests so I want to try fixing it myself.

making some diy workout stuff, and one of the pieces is a 12" pipe nipple. the diameter that i needed came in a black pipe, and once i got it home i realized its covered in some anti-rust grease or something
is there an easy way to get all this shit off so my hands dont end up covered in black grease everytime i use it?

What should I do with the scrap sheet metal I end up with from a plasma cnc? Like the stuff that is too small to repurpose for welding jobs: Is it worth my time to just throw all the small cutoffs into a bin, let it collect to a mass, and bring it all to a salvage/recycling yard? I have no idea if that is even worth anything, or if I'm going to have to deal with bullshit on "yer metal isn't clean enough boy". Wut do?

>>2455241
As opposed to just throwing it in the trash?
Just get a drum and throw the shit in there, someone will buy it off you eventually.

>>2455223
Threaten your jew landlord to fix it or you'll escalate legally. Why the fuck would you spend your own money on a place that you do not own?

>>2455131
I grew up dirt fucking poor, so we did /diy/ things that we couldnt afford professionals to do, that was for bigger stuff
For smaller goods, a lot of times its cheaper to just buy it instead of fixing or diying. Thrift shops or garage sales.

>>2455243
I'm talking like random corners and small non-square bits that are left from the sheets of metal I am cutting off of. If I could reuse them for other welding jobs I would, but this is all the misfit pieces that are left over. Can you recycle that and/or get money from recycling centers ?

/diy/ isn't necessarily cheaper, but you might end up with a product that's suited to your needs, or one that you understand the inner workings of and thus you can repair it easily. It depends on what you are making. Furniture and shelves are generally going to come out more expensive by a long shot.

I need to remove my bathroom faucet base to replace the cartridge because it drips, however I can only get it a little bit loose and it just spins and spins like it stripped. I can get it tight again just doesn't get fully loose. Is there anything I can do?
It was a real bitch to get this far and I had to hold the base under the sink with vice grips which makes me think it stripped doing all that.
It's just like this one, except all the faggots on youtube spin it off like nothing.
https://youtu.be/cOSYFIE4r18?t=32

So how do I get this off without cutting it? I don't even have tools to cut it.

>>2455244
how long do you think it has to go unfixed for before I have a case legally? like two weeks before it's deemed negligent on the landlord's part?

>>2455623
Well I don't think it was stripped because the other side is doing the same thing. What do I have to do to take it off then? It just gets loose and spins. I started cutting through the pipe off the first one but my saw is too shit to do it and I don't want to have to cut them both.

Hi I'm building a grow tent enclosure for a giant snake.
It it safe to block off the HVAC duct in my bedroom with a magnetic cover from home depot? Is thee a better way I should do it? Do I need to block off the whole vent? I'm only going to cover like 2 inches of it with the tent.

>>2455748
You'll be fine. If the house is anything close to properly ducted, then a little restriction from blocking off one vent isn't going to matter much, although obviously if you're in a cold climate it might affect how you heat the enclosure somewhat.

I'm insulating my garage. I've never done it before and the studs have a really annoying layout so I've mismeasured a few fiberglass pieces, leaving one inch gaps in a couple places. Can I just hit these with expanding foam before I drywall, or is that somehow not chemically going to sit well next to the fiberglass insulation?

Also, do I have to worry about which insulation I use around the wiring? there's wire running to a couple junction boxed through the studs and I know nothing about electrical.

How does a person figure the working time for a plasma cutter, welder, etc, when not running it at full power? I get how duty cycle is calculated when you have the unit maxed out, but what about when you're running it at like 75% max power?

I'm trying to figure how long I can continously run a 45 amp plasma cutter that has a 35% duty cycle, but I am only having it cut at 35amps.

Tried to remove buttplate screws on my gun, one snapped off. Imagine this pic with a rusty headless screw in one of the holes. Tried a screw extractor, useless since there's not enough metal there. Don't want to be rough on it or use chemicals since it might fuck the stock up. Thinking of taking a dremel and carefully cutting the screw into a Robertson head shape. Is it safe to use penetrant on it too? Any other ideas?

What is this? Some guy was here installing a temp system and now this is on my desk. Did he place his drink here, is it from a hot tool? Is this something I can fix?

>>2457444
Drill in all around it as close as you can get then excavate, or use a chisel to expose half an inch or so of the screw body then use vice grips, then drill it out 3/8 or 1/2, or whatever you need to, and glue in a piece of dowel.

>>2457466
My guess would be he spilled acid or cleaning solvent on there and the stuff messed with the paint.

Primer can’t exist on it own?

Any tips for sanding this thing down again? Can’t sandblast it because it’s right next to a glass front door and a driveway with cars. I was using a sanding block and a dremel for the curvy bits before but it took days

>>2457541
Well it depends on what you mean by "can't". Obviously it worked for you for a few years, and any surface coating is going to give out eventually under temperature/seasonal/sun/rain cycles. I don't know how long any given product is supposed to last in real conditions, though. I would imagine that more layers means that when the top coat starts to crack you can just sand it back and apply more topcoat rather than re-prime etc.

Primer *primes* the surface for the application of some other layer of paint or sealant. So if something is just a primer the intended use is to put something over it.

Handheld belt sander, maybe? Can probably borrow/rent.

I had a mattress delivered today. The movers chipped paint on the ceiling and wall of of the staircase. There are two small chips on the wall maybe 1/8" each, and a longer inch long but thin chip knocked off the ceiling. There were already a few chips to the paint in other places, but the delivery company added some fresh ones. I know the delivery guys did it because the paint flakes are on the stairs.

Is generally considered this par for the course or should I call up the company?

I'd let it go. I realize paint is technically damage but this is like them tracking mud into your house in terms of how much effort it actually takes to fix. Was it an honest accident, or were they fucking around and cutting corners when they damaged it? Were they working well otherwise? The only time I'd say something is if they chipped the paint but were shitty in some other way that the boss can address. The boss cannot make these guys into perfect precise machines, no one can.

You should have some sort of fume extraction or filtering. A cheap filter isn't expensive.

I just want to know a couple things about reclaimed wood. Found some wood that I think was flooring from a barn; has tongue and grooves, it's very old, pillbug eaten, and even has square nails, which places this wood as pretty fucking old. I'm thinking of making something out of it, but I have a few things I know will be a problem along with a couple thoughts:
>How do I make the cut edges match the old worn greyed surfaces it currently has?
I'm thinking the vinegar/steel wool trick, but I'd be open to suggestions
>How do I ensure I'm not going to fuck up my house with termites and my furs with pillbugs?
I've already doused the boards in permethrin. I'm thinking of also spraying it down with alcohol for drying and further bug killing. I want to seal the wood, but not coat it in some ugly thick clear coat. BLO doesn't work on weathered wood; it just turns dark brown/black and blurs any detail the wood may have had left
>Has anyone used diluted home-made walnut stain on this kind of wood before? How did it come out?
IIRC it polymerizes and could be a decent alternative to BLO along with a light clear coat.

I'm not inexperienced when it comes to making shit, just in a weird situation I've never found myself in before. The wood is old enough I'm very hesitant to try anything with it in case I fuck it up. It is very bug eaten, however, so it's next to worthless. IMO it's sad; was probably a lot nicer when it was chucked in the first place, or at least pillbug free. Probably "old growth", too.

>>2458323
i have that bit, and i also have a drill wire wheel, but i found that it did not work at all, the drill would just rotate right off the metal and the harder i pushed the less effect it had. the wire brush wasnt taking off any paint! I eventually had to use the sandpaper bits which only last about 5 minutes before i have to get a new one.

>>2458351
Damn. That's why a plug-in drill with one of those screw on side handles come in handy every now and then. Harbor Freight has at least one model like that. They do kick like a motherfucker sometimes and the second handle helps steady them. But in the small cracks, you could really only go Dremel. IMO, though, the wire wheel on them would just be too soft on something like that. Probably best to soak it in paint remover and use a dremel wire wheel over the whole thing. A pain, but maybe worth. Not sure how well it'd stick, though. Might still have to sand to rough it up so it sticks.

>>2458490
Tapered square ez out will be the fastest no nonsense no swarf left behind method, make sure the piston is bottom dead center so you don't accidentally ding it with the tip of the ez out. If you are lucky there might be a little booger of thread still poking out and you might have enough real estate to catch the booger with a sharp chisel and get it to spin out. First try a leather glove and your finger, as long as it wasn't corroded and shitty prior to installation it should spin out without much effort because there's no longer any shoulder to provide the lever that the screw threads use to create clamping pressure.

I think I can get them to use around 5w per fan for my needs which is great. My problem is where can I get fan blades that are the right fit for the pole and how can I attach them? Also, if I bore a hole into a stud, mounted the dc motor in that hole and ran the fans, would that be a hazard to the motor or otherwise?

>>2458662
Sounds like low charge. Battery cooked?

My Coleman Evcon Presidential furnace fan runs more than it should. The flame part of the furnace is fine, it goes on when it should and off when it should. But when the flame/heating goes off (because I turn the thermostat down or because the temperature gets warm enough), the fan continues running for many minutes. In the past the fan would stop shortly after the furnace stopped, but just as of recently, the fan runs for much longer (20 minutes? not sure) after the furnace shuts off. Why might this be and how can I fix it?
There is a manual switch for the fan so I can turn it off that way, but I want it to go back to automatically turning off after a minute instead of after 20 minutes.

>>2458840
The air handler fan or the inducer (combustion) fan? For the air handler, there are probably DIP switches on the circuit board to adjust the additional air handler fan run time. The inducer fan is controlled by the combustion logic; you aren't going to be able to change it.

>>2458840
That implies that the fan is not cooling the heated stuff as fast as before. Maybe the fan is going bad, maybe the duct or whatever is clogged, or something else has changed. If it's a simple temperature switch I think they just fail, but if it's a smart system with sensors and brains no telling what could have changed.

Pic related is an overtemperature protector, but some furnaces use a similar devices to turn the fan on and off.

>>2455223
Check for buttons, coins, bits of gravel, and other solid material - not just tableware.

They get stuck from rust/corrosion if not used frequently.
If it's an InSinkErator brand, (some others too) there should be a double-ended hex wrench in a plastic pouch glued to the side of the disposer.
The wrench goes into a hex 'socket' on the end of the motor shaft at the bottom of the disposer.
Wiggle it back and forth until it breaks free.
If it's not that style, the easiest way is to use a disposer wrench. ~$10 at a hardware store.
Same use, wiggle it back and forth until the plate breaks free.
S O M E T I M E S . . it's stuck so bad I have to use a flat blade screwdriver to go around the edge of the plate chipping away the rust.

Cycle it at least weekly to prevent seizing.

>>2458843
>>2458848
It's the really loud fan, not sure what type of fan it is, but I am pretty sure it is just to blow the hot air into/through the ductwork.
The furnace is 20-something maybe going on 30 years old, so I highly doubt it has any 'smart' features.
Right now it's been over an hour with the furnace turned off and fan is still going.
Does this info narrow it down at all? I don't see any sort of sensors but I don't know if they would be visible on the outside.
Since the change is so drastic, and since the fan still sounds the same as it always has, I am guessing that it's not a problem with the fan itself going bad, but what the fuck do I know.
Thank you

>>2458848
Also, you said the fan isn't cooling the heated air as quickly as before. Does this mean the fan keeps blowing until the temperature of the air in the furnace reaches a low enough temperature?
If I manually turn off the fan before this happens, does that present any fire hazard or any other danger if that means the temperature is staying hot with the fan not running to cool it?
Sorry if retarded question

Would it be possible to incorporate a massive flywheel as a power backup system in a home?
Imagine using a small electric motor to slowly input electricity into a huge flywheel setup in your attic or basement. The RPM can be monitored electronically and once you hit a threshold you would stop feeding the flywheel. It could be set to slowly "rev" up over many months/years and maintain a stable RPM while only occasionally siphoning power from the mains to charge it.
Once your power goes out you could have a break flip and then the flywheel begins to feed an electric generator in your home to power certain devices.
No need to worry about batteries or fuel for a generator, it would just hum along in the normally unused space in your home until you needed it. It could be incredibly large and heavy, since it's not in the way of anything. On top of that it would never need to be removed, maybe just suspended for maintenance on bearings or the electrical systems. It won't last as long as a generator but most power outages don't last more than a few hours or maybe days depending on the circumstances.
Is this a dumb idea? Anyone ever look into a similar system?

>>2459021
Sounds dangerous if such a thing were ever to fail. This would be something absurdly heavy, no doubt, or something with a hell of a lot of stored energy. If it slips off its mount, god only knows what it's going to destroy. That being said...
https://www.youtube.com/watch?v=yhu3s1ut3wM
https://www.youtube.com/watch?v=gahKxbwUcYw

>>2459021

Not a new idea. Also not really practical. If you don't want the thing wasting a bunch of power, you basically have no option other than to stuff the thing in a vacuum chamber, which skyrockets the cost and complexity of the system. In order to store enough power to be worth a damn, you also need either an extremely large, heavy flywheel, or you need the thing to be made of carbon fiber and spinning at ridiculous speeds.

Meanwhile, a small engine, protected from the elements, will have no ongoing operating costs, readily-available replacement parts in the event it fails, and can store weeks months of energy in various, common fuels.

There are certain use cases where flywheel energy storage makes sense, but "household backup generator" is not one of them.

>>2459021
Flywheels don't store a useful amount of power for sustained use. They are very good transfer sources you can keep them synced up to the mains voltage and switch over to them literally seamlessly. It can give you 15 minutes for your generator to start and come online.

But not running your house for 8nhours. Nah.

Do NOT buy a USB mic, do NOT buy a Condenser mic. USB mics all suck dick, condenser mics are made to pick up everything in the room (and outside the room) and are impossible to use unless youre in a soundproof room or run a ton of gates and filters which hurt your sound.

Most people just get by with a shitty Blue Yeti and fighting with tons of noise gates. And that works fine, but its not hard to beat it at all with that budget.

Any DRYWALL EXPERTS here?

I ran out of quick-dry joint compound so I used All Purpose to fill a pretty thick gap.
Two days later it's still a little soft if I poke it with my fingernail.

Can I proceed with my final coat then prime and paint?
Or do I have to wait until the All Purpose joint compound is 100% hard before putting on another coat?
The final finish isn't a big deal, the wall is in a utility room, I just want to know whether it'll cause me problems if I put another coat over "mostly dry" All Purpose.

>>2459282
>a utility room,

You'll be fine.

I'm interested in building a muffler for my shopvac, however I want it to be a bit more calculated then thowing a couple of PVC pipes together with some stuffing, I want it to be a reactive muffler. I've downloaded a book on muffler design, however it's a high-level scientific book with content like picrelated.
It wouldn't be too bad since I have a degree in mathematics, however I'm not great with physics and I have a hard time understanding the meaning behind many of the equations in there.
So I seem to need one of the two things:
1. A more entry-level accoustics book that might give me understanding of concepts like particle velocity and pressure perturbation and their connection to sound, etc.
2. A non-scientific book/article with muffler design that has some basic formulas for calculating resonating or interference chambers depending on the noise frequency.
If anyone knows of such books, please recommend them, that would be appreciated.

>>2459218

>>2459282
>I ran out of quick-dry joint compound so I used All Purpose to fill a pretty thick gap
It will shrink and crack. Depends how thick.
Compare that to quick-set mud, which doesn't dry, it actually cures. Kinda like concrete. After 20-90 minutes (depends which flavor you got, or what kind of minerals your water has) it is wet, but solid and you can coat it after that.
>Two days later it's still a little soft if I poke it with my fingernail.
Let it dry completely.
>Or do I have to wait until the All Purpose joint compound is 100% hard before putting on another coat?
Yes.

Just don't mess with the bricks, too fuck up the foundation of a brick wall you would need to use a sledgehammer anyways. You can use a mason spoon to scrape off all the plastering on that wall and it would still be safe.

Whats the best way to make diy leveling feet for a desk/workbench? I am going to be putting in a workbench type space in an alcove in my basement and the floor is not very level.

How do you cut straight with a portable bandsaw? I'm specifically using an m18 Milwaukee Fuel. Asking because my journeyman keeps griping about me not cutting copper pipe straight with it, but everything I've tried and every kind of reference point on the bandsaw hasn't worked. The closes I've gotten is using two wooden boards or pieces of strut, but I sometimes mess up even then. I also see people with varying levels of experience more than me fucking up just as bad, even my journeyman. Is it just that hard?

>>2459491
>Can i just screw it to the cabinet next to it without screwing it to the wall?

It has drawer guides so, it's a base. It should be fine to not screw it to the wall.
Face frames shoud be screwed together anyway.
It would be best if it had full depth cases on each side to keep it in line with the other base units.
Make sure you have the face aligned with the others when you attach it to the countertop.

>>2459499
>How do you cut straight with a portable bandsaw?
Practice.
Focus on just the blade and it's relationship to whatever you're cutting.

>>2459458
There are many better ways, but I'm assuming you have some budget and work and tooling constraints, in light of that, the threaded inserts are fine. Maybe get some rubber feet with embedded bolts, that's a bit less shit than using the bolts alone, will probably dampen the printer noise a bit as well. They're usually sold as anti-vibration feet.

>>2459675
Your panels are 40V 10A, so you need either a 40V 20A or a 80V 10A charge controller. Chinks sell various controllers of this range,
https://www.aliexpress.com/item/32956247199.html is probably the cheapest (not the cheapest listing, just the model itself).
Note that PV input still tends to depend on what battery you want to use it with, like this one can take 20-80V for a 12V battery, 37V-105V for a 24V, 72-160V for a 48V battery. It's usually better to use a higher voltage battery.

I guess these things aren't water proof right? Regarding battery I just wanted to use a bunch of AGM's since its primarily supposed to work as a backup for emergency.

>>2459735
This one in particular isn't, but there are more outdoor-compatible units. I don't think there are any that are fully waterproof, maybe some marine units.

>>2459734
Won't the sand be too abrasive for the bit?

>>2459739
Small size bits cost like $0.10 and you can sharpen them, not that they'd need sharpening after drilling into sand a couple times. Of course if you want to drill a throughhole, you should just mark two holes on the opposite sides and drill each from the outside, rather than go through.

Hi i have a question about what screws to use when installing cabinets
I looked on google but theres so many different answers and my brain is a bit scrambled
So do i have the right idea that when securing cabinets to wall you use 3 inch #10 screws?
And when securing a cabinet to another cabinet you use 2.5 inch #8 screws?

>>2460548
> securing cabinets to wall you use 3 inch #10 screws
sounds okay
> securing a cabinet to another cabinet you use 2.5 inch #8 screws
depends on the construction of the face frames
I try to get ~1" penetration into the frame being pulled.
If the frames are 1-1/2" then 2-1/2 inch is fine.
I like pic related screws. Washer head won't split the wood.

That's literally not possible unless you're too retarded to function. You don't even attach vinyl plank to anything, in the worst case if you totally fuck it you're just out materials for any pieces you cut wrong, and the time it takes you to pull it all up and try again.
