I got a hole in my ceiling.
This was caused by a leaky roof, which has been fixed temporarily (they put a tarp over it).
The problem is that my mom won't fix the roof properly for a few months, so she refuses to get the ceiling fixed for fear of the tarp getting weathered/damaged in which case water would again drip and just ruin the ceiling again.
So I'm wondering if there is some way I can temporarily seal the hole because we have all sorts of critters in the attic (mice, raccoons, etc.) and I don't want them getting in my room, I've already ran into a couple close encounters.

I've got a project that involves cutting lots of 1" dia holes in 1.5" thick sheets of Styrofoam. The little particles get everywhere. Here are the things I've tried:

Making a punchout tool out of some copper pipe I had laying around. Works OK but the holes are ragged and foam crumbs get everywhere. Making a hot knife out of a wood burning tool I got at goodwill and some stripped solid core electrical wire. Works OK but it's slow as hell. Making a melting tool using a small section of the pipe heated with a torch. Works great but the heat is hard to control and leads to overheating which makes the holes too big. Hot knife v2 using a circular bit I made out of the pipe (pic related) and attached to the wood burner. Slow even when I drive the wood burner with a Variac at 140V but works best out of everything. I tinned the connection with solder to help heat transfer.

Any other ideas? Wood burner is 23W, I know a bigger heater would help. Would it help or hurt to cut more material off the tool I have now?

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.

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).

These handrails are rusting pretty bad. My plan is to use wire brush on a drill to get the bulk of it off followed by spot sanding and mineral spirits to clean. I already tested a small section and it seems the paint comes off easily, but there are about 10 layers of it dating back to the 50's so probably lead in there.
My questions are: Do I need to get every last bit of rust out of the pitting? And should I get spray paint to do the final coating or stick with a brush?
The final colors will look similar to how it is now, white for the bulk, and a pastel for the curly accents

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

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.

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.

hi guys, I live where there is little to no water at all (yeah, we're in a drought) So my idea was collecting rainwater in the most cheapest diy way possible. I've looked up some things online and they all mention purifying rainwater to drinking water. I only want it for showers and washing dishes...

Originally I was just thinking using tarp, a tube and a shirt to collect and filter said water, but seems like I'm going to need more than that... Any tips...?

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.

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.

>> No.1184683

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.

> implying not trole

You mean your wall wart, or the regulator on the circuit board inside the keyboard?

Hey so this is a 1watt laser, runs off two 3.7 volts, i pulled it apart to repair the battery compartment, it was loose. I ended up having to replace the spring part that the negative part of the battery connects to, i put it in a base of soder. I have no idea why the beams so weak now, it was strong for about 50 secounds before it dimmed. The batterys are charged.Also the compartment with the diode heats up when its on, pic related. my best guess is somehow the current is connected to the casing making it weak, but i dont see anywhere thats possible. Any ideas on how to repair it?

>> No.1184654

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.

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.

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.

That's where I draw the line of how much effort I am going to put into making it a fully legal functioning vehicle...

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...

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.

Will this stuff make decent concrete reinforcement additive if shredded? It's orders of magnitude cheaper than the white uniform length fibers you usually see in GFRC...

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

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.

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

Has anyone ever tried to make one? Its basically a motor with a prop attached to a aluminum dock pole, priced at $2,000. I was thinking about using a battery powered trolling motor, or possibly some type of pump. I have tons of weeds floating up to my shoreline.

I bought a custom built home from the original owner. I want to make some structural modifications to the house. I am a licensed structural engineer, so this will not be an issue.

I would like determine the size and spacing of my roof joists (without cutting holes in the sheetrock). The owner was not able to provide me with any building plans for the house (he died). Is there typically a permitting department at the city or county level that would have a set of plans?

The home was built only a few years ago, so I am hoping that there is some record of the building permits or at least who the architect was. The problem is that there is no "building department" nor a "permitting department" in my county. Is there some other name that this department goes by?

I am located in burgerland

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

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).

I have two large floor speakers somewhat like pic related. The cone/diaphragm has been eaten away by age and they've long since been blown out by abusing max volume by whoever owned them before. Still, the wood is nice and I'd like to repair them if I could. Has anyone done this before? I'm going to try ordering a new speaker assembly and wiring it in myself, but I'll have to seal it properly somehow since the model doesn't have replacement parts anymore.

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?

>> No.1184509

>>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).

>> No.1184547

>>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.

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