it's not my decision and i won't be the one doing it
will roofers charge extra on account of it not being fun

>>1185050
very cool brother

>>1184830
drag a full sheet of plywood up into the attic, and lay it over the hole from above. Problem solved. Next thread. You guys are really hopeless sometimes.

>>1185074
i can't do that because the attic is inaccessable
it never occurred to me how easy it would be if it was though, damn lol

>>1185074
>>1185079
Actually I just realized it had occurred to me
the reason that won't work is because the joists are clearly in the way
I came up with this idea while staring at the hole in my ceiling with the lights off, so all I could see was a big black hole, no joists
what's ur excuse for comin up with this birdbrained idea

am i the only one who still sees a hole in OP's photo. the little spot of the light in the roof?

Switch to a denser and less crumbly type of foam. Blue or pink foam.

Make a makeshift die and press, isn't that hard.

You made this exact same thread like 4 months ago. wtf

>>1184818
Cut a hole the size you want in metal plate, put that hole over the place in the styrofoam where you want the hole to be, melt styrofoam with heat gun.

Do not stick dick in heat gun.

steel and battery, pivoted like a compass

Model plane folks use guitar strings for their foam cutters.

Artsy office chairs tend to be weak, you might be able to weld that back in place, although cheap office chairs seem to be made out of shitty pot metal.

When the plastic armrest of my chair snapped I fixed it with aluminum plates and screws, but I don't think it's applicable to this situation.

>>1184804
Don't really have access to a welder or any other heavy duty equipment.
I think I'll just keep the seat to use when I'm playing guitar.
Probably gonna throw the back out.

>>1184800
Ok I'll ask around and look into those, and my dad used to work on TVs so i called him up and we got it all removed.

And yea it's just shitty wood, nothing special at this point.

>>1184782
>got rained on hard before I got it

Just dry it out for a few weeks. There was plenty of room in those for dozens of pis so no need to gut anything.

>>1184786
depends on how old it is. I tore up one of these that was actually solid wood on the front panels and decent plywood for the top and sides and bottom. I tore out the guts and made a shelving unit/book case out of it. I had another one later that was MDF fake wood crap - that one went to the electronics recycle. and yet another one later that was pure plastic fake wood. that also went straight to the electronics recycle.

>>1184759
>>1184764
Fuck off back to your containment board >>>/vr/

>>1185067
This one's a mix between wood and panels, I think the original owners refurbished it at some point. If I get lazy or this project is too much of a bitch I might steal your idea for a bookshelf.

>>1184720
In the photo its two separate singles arcs. I only know of tandem or twin-arc welding with the SAW process.

tandem welding : 2 wires, both with there own power source. contact tips and wire-feed

twin-arc: 2 wires, one power source and they share a contact tip and wire-feed.

the 2 wires go in the same puddle.

>>1184720
This is common place in the trade industry. Two electrodes 2 grounds

We do this a lot at work and I was wondering

How does the current "know" which ground to come back to? Don't the currents mix up sometimes or something?
For a welder I shouldn't know this little about electricity.

>>1184809
Imagine filling a vertical pipe from two holes at the same height at the top. They're attached to the positive pressure end of separate water pumps each. The suction/negative ends are connected to two similar holes at the very bottom. The pipe is sealed, filled with water, and the pumps are run. All things being equal on both sides, they have the same current, _gravitational_ potential difference, and heat the pipe walls the same amount. Water molecules turbulently go wherever, but to the same effect.

The electrons in the electron sea of the metal you're welding to act the same way in the presence of their 'electron pumps' (voltage sources, in this case v. powerful ones).

>>1184812
That's a good way to put it
Thanks familam

So I had a dremel in the basement with one of those sandpaper rotating heads so I gave it a try and bam it got that paint right off. Turns out these handrails aren't at rusty as I thought, just caked with layers of old paint and some cracks. The curly parts are the worst, the white areas less so, but it still took hours because that wire attachment didn't work as well as I'd hoped, and I only got half of one rail done

>>1185103
because you're using the wrong tool. you need an angle grinder with a wire brush head, not a drill.

>>1185112
THIS.

I once took the paint/ rust off this old guys rail on his front porch. Shit had like 5 layers of paint with rust in between them all. Had I not had an angle grinder and wire brush I would have lost so much labor scraping and applying naval jelly. Once you do that you'll be left with a few rusty pits and tarnish, hit it with some primer and hammered metal paint and it'll look brand fucking new.

>>1185072
I like your Christmas tree.

>>1185112
>angle grinder
This is an excellent suggestion and I'll go a bit further and tell you to get a cheap one with not a lot of balls. A fast grinder with a lot of torque will bounce you all over the place. Dangerously.
Too many rpms and you'll end up kinda polishing the good existing paint.
>You don't want fast and you don't want torque. You want to be able to bog it down.

I live on acreage, so my 4D maglite is a daily use item.
I bought an $8 led bulb from Lowes.
Its 3x brighter and standard D cells last about a year.

There's a lot of different options, like
>>1184724
But if you just want the simple upgrade, it's as easy as changing out a dead bulb.

>>1184752
you mean other flashlights?

not a very impressive collection by CPF standards; couple of older 18650s, $5 cree lights, and a better version of those that also takes an 18650

https://www.amazon.com/UltraFire-300lm-Flashlight-Torch-Adjustable/dp/B006E0QAFY

https://www.amazon.com/UltraFire-Adjustable-Waterproof-Flashlight-flashlight/dp/B00CJO65SQ

^this one is usually the one I use the most, nice wide flood and plenty bright....although the single AA ones are great to have since the batteries are more readily available

the maglite is almost too bright to use inside, I wanted a good thrower if I go out walking at night....the module I chose is single mode, $20 shipped from dealextreme

>>1184703
I have one of those old maglite. I made a Joule-Thief-like circuit and put a 3w led on it.
It works, but is not awesome. Not for a 2D cell at least.

>>1184806

>>1184806
could you elaborate more on the circuit?

>>1184692
First look up your laws because many places have laws against collecting rain water, especially during droughts. Second, if you want to collect rain water without fucking over any soil that desperately needs it (as if there was a drought or something) I would make several smaller rain collectors that feed into pvc pipe that feed into a large container. It's a good idea to filter out the shit from your water but you probably want to use something better than a shirt. A window screen cut up and layered several times would work for all the big stuff.

To purify, you'll just want to use chlorine. You can put chlorine in water enough to purify it but also keep it safe to drink. You could boil it but it would take a long time to heat up to boiling point then a long time to cool down. Also de-oxygenated water sucks to drink for any extended period of time.

>>1184692
I have pic related, only much larger, like a "fema" coffin (around 1000l in volume), connected to my gutters in my back yard, it's 3 meters over the ground, over a wood beam structure that also serves as a tool/broom closet. I have a hose running down from it into a tap.

I use the water to water the plants and wash things. You don't need to do much maintenance, only removing the sediment after a couple of years.

>>1184715
Well if OP is in a house the roof is prime space there for rain collecting.

>>1184777
This. You could build a water tower with the inlet coming off the gutter downspouts into a sand/charcoal filter tank (pic related). The result would be safe for washing, or it could easily be treated further for drinking water.

Use propper punctuation and give detailed information if you want to be understood.

If you grounded a regulator that wasn't supposed to be grounded maybe it's loosing power throught the ground or not working properly.
If it works don't fix it.

I suppose your piano uses an external "brick" or "wall wart" PSU, check if the current rating and voltage of the PSU you're using is the same as the one you replaced.
Higher notes have higuer frequency and require more energy to drive the speaker, maybe your new PSU is underrated.

Btw. I don't know much about electronic pianos, but I haven't seen any piano powered by 5 volts, even small pianos I've seen run on 7 or 9 volts. Again, check the old psu's rating matches with the new one.

>>1184677
> implying not trole
> grounded regulator
You mean your wall wart, or the regulator on the circuit board inside the keyboard?

> something something keys not loud
Higher keys are quiet compared to the lower keys? Or not working at all?

Maybe the new spring and the solder puddle are causing excessive resistance. But that doesn't explains the 50 seconds before dimming. The diode heating up is kind of normal I guess, but not at such low power.
You maybe fried it somehow.
Many flashlights use the case as a conductor, which is fine, since aluminium is a good conductor.

Try taking the diode (and the driver board) out of the laser and test them with a PSU, if the problem persists something is wrong with the diode/driver. Be careful with polarity, the case is often used as the negative conductor.

>>1184654
thanks anon ill try that out

>>1184645
you can't call them that! it's racist!

it is 2017, get with the times

>not calling them paddle bits

also, forstner bits, hole saws, and paddle bits all have their own purpose. there is no superior bit for drilling

>>1184685
The broken one, 2nd from left, wouldn't that be a bit of spade?

>>1184754

We call them fly bits.

I don't know why

>>1184754
Paddle bits' purpose is being cheaper than forstner bits. Hole saws are good as long as you only have to drill shallow holes.

>>1184621
You ain't gonna get an acceptable MIG welder for that budget, man. Trust me, I stick pieces of metal together for a living.
Either get a stick welder and git gud or save more money and look into used hobarts and such.

>>1184808
My main question about your statement I guess would be, are you going off of company tools, or are you speaking from a hobbyist point of view? Kinda like comparing Snap-on and Craftsman, they're both tools and generally do the job. Not questioning your experience, but if I just need a lower powered welder, what're the benefits, besides being more flexible?

>>1184794
I've seen those in action and they seem to work pretty well. I've watched some of ChrisFix's stuff, and he's not an idiot. I'd ask the folks at HF where they sell em, but they're not the brightest people around...

>>1184638
Can't really help you as I live across the pond. Proper tools are called kemppi, esab, Wallis, migtronic and the like. Yours probably differ. Also shit runs on three phase here so powerful welding machines in the 300-600€ category are quite common.

I second >>1184808 here. New machines in your price range are good for thin metals. Used bigger machines can be tricky to buy if you don't know the scene but usually they deliver. Not always though.
I don't know what kind of voltages and phasing industrial surroundings uses in your area but those are what I aim for. As every building over here has a 3~ plug somewhere it's easy to buy used industrial equipment, you know its always going to run at your home also. I don't know if the case is the same where you live so can't really recommend.

>>1184819
if you ONLY want to do car body and exhaust tubes, a tiny mig is fine! in a hobbyist setting it doesn't even need to be a good one, really.

but here's the deal: a ~200amp mig does the thin stuff, but can also handle the bigger auto jobs like frame rail patches, sticking nuts to busted locking lugs, and general fabricating up to about .250 wall. it would have better consumables/spares availability, more reliable wire feed, a better torch, finer speed control, more voltage steps, and a place to chain up your gas bottle safely.

buy once, cry once.

>>1184546
12 hour bump.

check out etching, it doesn't require equipment. Otherwise you're looking at metal cutting devices which get grit everywhere and needs workspace

>>1184546
look up electric etching. all you need is masking (for the part) a couple nine volts alligator clips saltwater and a sponge. obviously better equipment equals better results. here's a link to the first video i found.
https://www.youtube.com/watch?v=lTInRaM2eTw
if electro isn't your thing I've heard ferric chloride is similar, but less user involvement. its often used to etch one-off circuit boards. also early link.
https://www.youtube.com/watch?v=gtK7Erd3Hn8
if your working with no-corrosive metals either tiny chisels, or pony up the $300-$∞ for a cnc machine like this one. http://www.ebay.com/itm/Hobby-Desktop-3-Axis-Mill-Small-CNC-Machine-DIY-PCB-Milling-Engraving-Router-Kit-/111891372282. cheers mate.

>>1185137
or a dremel / non-dremel dremal (small rotary tool with interchangeable bits, hand held), but it takes almost as much skill a cutters and it makes a mess.
https://www.amazon.com/Genesis-GRT2103-40-Rotary-Tool-Accessories/dp/B00885ZI06/ref=cm_cr_arp_d_product_top?ie=UTF8 this one is shit but you get the idea

Op here, thanks for the replies. I feel stupid, because I see I didn't explain fully.

I'm wanting to do the engraving on the wax blanks I'm using to do the casting. Any recommendations for that?

>>1184527
Lol no, it's fucked, don't even try to fix it.

>>1184842
How does spending half a day with a hammer on a day off take away any effort from saving up from a new car? Simply put, why not both?
I realize it will never be like new, but at least I can make the door seal more correctly...
>>1184876
My mechanic friend actually recommended I make the other Mazda I have run with parts from this one. However, the other one is literally just the chassis now, which would mean I'd have to transfer everything... Which I'd rather not. That's where I draw the line of how much effort I am going to put into making it a fully legal functioning vehicle...
>>1184910
Again, the car is fine, it's just legally totalled. I don't see why taking a hammer to it for a few hours will do any more harm than is already done...

>>1185061
If the car is legally totalled you cannot have it back on the road beyond processional tier restoration. Period. End of story. You fucking troll.

Just go buy something for $500. It would be less effort than this and safer. You got a job, so you could apply for a bank loan.. and start establishing credit worthiness. If a $500 loan default sinks you.. ( you cant pay it off) well then you need to start studying a trade.

>>1185061
>Simply put, why not both?
Get a hammer and go to town, post results

it tastes pretty great... I don't know much more than that

>>1184483
It's quite puffy and thin like wool, so it probably will only introduce air poquets.
If you reduce it to the fibers, they are so thin it probably won't add much reinforcement.
The ideal thing is having sommewhat thick strands in random directions without puffing up.

>>1184483
>Will it make decent reinforcement

It will reduce the strength of your concrete by an order of magnitude if you fuck it up just a little bit.

>>1184475
Right on. F*#k those weeds!

>>1184419
Custom built doesn't always mean that Jesus and his amigos followed the gringos blue paper exactly. You can hide a lot of stupid behind drywall...

You misunderstood the intent of his message

>>1184445

you want to "make some structural modifications to the house", but dont want to cut a hole in the drywall to poke your head up in and have a look around?
might as well just quit now.
fucking engineers, i swear

>>1184408
You're supposedly a licensed structural engineer by the county or city and you have no idea where to get plans if they exist?

Bullshit

As a structural engineer you'll obviously know the code adopted by the governing body and that will tell you. I mean I feel stupid saying this on account of how obvious it would be for a licensed structural engineer who needs to know the adopted code for the region in which he operates.

But, then again, you probably ARE an engineer since you're too fucking stupid to climb into the attic with a tape measure

>>1184619
>You're supposedly a licensed structural engineer by the county or city and you have no idea where to get plans if they exist?

I don't deal with residential construction

>As a structural engineer you'll obviously know the code adopted by the governing body and that will tell you. I mean I feel stupid saying this on account of how obvious it would be for a licensed structural engineer who needs to know the adopted code for the region in which he operates.

There is nothing wrong with wanting to see it on paper before I start doing work. The existing conditions may alter my plans (i.e. I might alter my additions to conform with what is already in place).

>>1184402

Alternately, cinder blocks and a sheet of melamine.

>>1184356

Get screws. Get wood. Get wood glue. Glue and screw. You've got yourself a table.

Go on gumtree/Craigslist/Local paper search for free or cheap table frame.
Buy/acquire a plywood sheet. Cut to shape.

Making myself a tv console shelf. Is screws good enough for all the joints? I can try dowel but then I have to carry the whole thing myself than screwing them piece by piece in my bedroom.

>>1185217
Oh yeah nothing heavy, tv will be wall mounted.

>>1184357
Alright I'll write that down. I'm basically replacing everything inside the wood case, so I might as well refoam it too. What else should I keep in mind?

>>1184361
Naw man. What I was saying is that you should keep the "drivers" or "speaker cones" that you have because replacing them with something else will change the frequency response of the speakers. You can repair the cones by using a foam repair kit (eg.http://www.ebay.ca/itm/FOAM-SURROUND-REPAIR-KIT-FOR-JL-AUDIO-12W3-12W3v2-12-SPEAKERS-SUB-SUBWOOFER-/380398805273?hash=item5891892119:m:m2Vz01g6WjhoWLAXbD7Nhuw) You may have to find a kit for your specific speakers, although a generic kit may also work.

As for the other components in the speakers there will be something called a "crossover" which is a passive circuit that acts as a filter. It filters the audio so that the tweeters get the right amount of high stuff, the mids get the right amount of mid stuff, and the big bass drivers get the low stuff. If it has electrolytic capacitors, replace those.

It is possible that your tweeters could be dead. You will be able to tell if they work by listening to them.

Other than that, the cabinet will be full of insulation and you can just leave that alone. You may wish to replace the terminals of the speaker with a more modern form of hookup (eg rca) if they are using old type of terminals.

>>1184348
Post the make and model. It should be on a sticker somewhere. Maybe on the back of the unit or maybe under the speaker grills. If you can, post a picture of the 'eaten away' damage. That will tell us if it's just a rotten speaker surround (easy fix) or a damaged cone (shitcan it).

>>1184357
This is what I did to fix my Minimus 77s. It was a pretty straight forward procedure, and I just ordered the cheapest foam surrounds that I found that could fit. I used Alleen's tacky glue to attach them. I did this last year, and they are holding up really well so far. I also played a sine wave through the driver to make sure that the voice coil is centered.

>>1184348
If they are decent enough, you can often find parts. Audiokarma have an area to request parts.

this isn't twitter

It makes a nice substitute for a fire pit? Cats would enjoy sitting on it? Could be used for raising bread? build four more and they could replace a space heater.

>>1184304
No, this is patrick.
