Welcome to /diy/, a place to:

Post and discuss /diy/ projects, ask questions regarding /diy/ topics and exchange ideas and techniques.

Please keep in mind:
- This is a SFW board. No fleshlights or other sex toys.
- No weapons. That goes to /k/ - Weapons. The workmanship and techniques involved in creating objects which could be used as weapons or the portion of a weapons project that involves them (e.g., forging steel for a blade, machining for gunsmithing, what epoxy can I use to fix my bow) may be discussed in /diy/, but discussing weapon-specific techniques/designs or the actual use of weapons is disallowed. Things such as fixed blade knives or axes are considered tools, things such as swords, guns or explosives are considered weapons.
- No drugs or drug paraphernalia (See Global Rule 1). If you want to discuss something that could involve such things (e.g., carving a tobacco pipe from wood) that's fine, but make sure it's /diy/ related and doesn't involve drugs or it will result in deletion/ban.

Helpful links:
Some friendly suggestions for posting:
- First ask Google, then ask /diy/. Your question will probably be better received if you do so.
- List available resources (tools, materials, budget, time, etc.)
- Try to use pictures and explain the goal, if possible
- Be patient, this is a slow board; your thread will be around for days.
- Share your results! /diy/ loves to see problems solved and projects completed!

>5)also as mentioned- this shit smells. bad. I think that the paint from those cans is not ment to be inhaled... remember about your neighbours

Pre-incinerate your cans. Get a barrel, or a fire pit or something and just throw them in. It'll burn off the rosin coating on the inside of the cans, burn off the exterior paint. Just a regular fire will do.
It's cheap an works well enough, but it doesn't last long
It's very sort, and crumbles after a pretty short time
Get a metal pipe and you don't have to worry about PVC
if you don't have even 1/2" clearance between your can and the crucible wall, your crucible is too small.
Just melt hand crushed cans until you have a pool of aluminum, it doesn't make a difference

Hey /diy/ need some help on where to find electronic components. The radio shack in my town closed and im pretty sure thats the only place that would sell components. I dont really wanna order parts online but that seems like the only place that would have them. Are there any places that you guys know that I wouldnt think of?

I'm also interested in this topic.
What does /diy/ think of mouser?
If you don't wanna order parts online, then you could just drive to China.

Seriously, there isn't any walk-in store in the whole USA that has the variety of stuff you can mail-order.
And a lot of the stuff from China costs 1/10th what US companies charge.

Go on someplace like aliexpress and search for "assortment" and the following terms:
electrolytic capacitor
ceramic capacitor
film capacitor

Hey there, folks.

Hoping to get a bit of advice on how to deal with this chair I just found. I'm sure a decent sanding with some fine grain sandpaper will help it out, but what would be a good, simple, way to come at it after sanding? I just want to bring it to life a bit, and protect the wood.

7 replies and 2 images omitted. Click here to view.
I'd give it a quick sand down here and there, nothing too harsh, and give it a good oiling, linseed or something, just to bring out the natural wood colours.

Then I'd whip out the sewing machine, grab some velcro scrips, and make me a cushion for that.

It's a lovely looking seat. A great find.
I've been on 4chan for fucking ever and didn't know this, thanks!

Great, thanks folks. I'll look into all that. And yeah, it's in great shape, too. Not shaky or anything.


Don't be mean, it's clearly some liquid that pooled into the contour of the seat, likely water.
water don't discolor like that, however, rotting shits would, also, the stain is obviously originated from someone's anus judging from the position, if it is pooled, it wouldn't have irregular shape, and goes up the central ridge towards your anus. It is undeniably a shit stain.
>water don't discolor

You don't work with wood do you?

Diy Ice machine. Been toying with the idea and gathering parts. I have THREE used ice machines and they suck my ass. They are too heavy to move, and only 1 woks but doesnt keep ice and is the size of my fucking car. I cant imagine what my electric bill would run if i lift it on. So onto a more manageable and redundant system. A chest fridge with side by side fridge ice makers installed. Theoretically 1 would fill it but take a lok of time and wear. In tslking with a repair guy i have lesrned a few small tricks to repair them but generally it is cheaper to toss the fuckers when they go. The cheapest ice maker "kit" i can find is about $90 pic related. I dug a little. Could maybe get the price down but not a lot.

On to the kiddie didler down the road. He buys pickup loads of shit appliances, repairs them, and sells them in his front yard. Hes all the time junking fridges.

If not i come acceoss used ice makers from time to time.

Ive looked into the tabletop ones but they dont pruduce fast and im not bailing water in the things. Hose or gtfo.

So, has anyone ever tried this?

I have 3 working ice makers and a small chest freezer to try it with.

The wiring might be a bitch. Some have like 5 wires. I'll get pics tomorrow of all the ones i have and the wires. Ive also heard no drilling in the sides as they house coper coils. Lid only.so ill have to be careful about water delivery and maker placement. Or build a drop bracket to mount them to the lid as im sure the 90 orientation will fuck shit up. If i ran these to switches i could easily colect a dozen of these things and flip switches as i need. If no hury just run a couple. If i have a big weekend and need a lot of ice we dim the lights and enguage warp.

I just dont see why i only found 1 shit one online. Why do more of us not have freeish ice machines? so what if one goes out, unplug it and throw it away?
These ice makers activate a 24v'ish relay connected to the cold water line. You'll need to tee into that.

I just want an ice maker that poops out 1.5" cubes or something that size. All these ice makers make small volume ice either to satisfy 'eco' water usage labels or because the motor to dislodge them are weak/cheaper.

I've been on the lookout for a small top opened freezer for cheap - haven't come up with anything yet.

Are truck brand toolboxes worth the cost?
26 replies and 1 image omitted. Click here to view.
Not in the slightest, it's almost 8 inches shallower and can't hold 6k lbs without breaking. Also finish is shit compared to a snappy. If you go cheap buy a husky box, they are better and cheaper>>1074875 it's all a matter of preference and in my opinion I would take a used snap on over a a new high end box such as a montezuma (which a comparabl box costs about 9 k)
First off, a US General Hodor Freight box is much, much heavier duty than a Husky. And the powder coat finish is very nice.

Second, how the fuck can you even fill a 72" box with anywhere close to 6k pounds? Are you filling it with lead?

you can't reason w/ fucking Snappy fags
He's just full of shit. That's all.
Two things:

Until 2010, both HF's boxes and SnapOn's boxes were made from components manufactured at the Stanley factory in Smith Falls, Ontario. The finishing work for SnapOn was done in Iowa, for HF in Canada.

2: With the Stanley Tool Works closure in 2010, component manufacture went to China for both companies. Again, Chinese made components assembled in Iowa for SnapOn, with HF keeping everything in one spot.

Long and short? There's a reason that the two boxes are comparable, they're completely the same. Parts off the same line, and it's been that way since the 90's.

This is probably a dumb question, but...

Would it be possible to reinforce a seacan by placing it in the hole, creating a rebar cage around it, then pouring in concrete 6" thick out from the walls and the roof, then burying it?

If all that concrete would be too heavy to pour at once, could it be pouted in layers? (1 ft at a time around the walls and then maybe 3" at a time for the roof)
Stuck in a hole with a bunch of stinking whiners fighting over a cracker is a fate worse than death....
You can bury a can and it will not collapse if you encase it in 6x6 timbers. 300 10' timbers will do a 40' high cube will set you back 3-5k USD

This work?
Concrete doesn't stick to itself. It's a polymer that's doesn't bond well when you just pour more on. That's not to say it won't be strong, but not nearly as strong as if you did it all in one go.

computer engineer from bangladesh university, right op?
To bring the drooped beam into position, I use playwood under the metal post to spread the point load onto the floor sheeting but it's failed. Floor is cracked and upon inspection from the basement, joist is snapped. I need urgent help. It's not my house, it's belong to step mother. She said she evict me if I do not fix this one.
There's your problem. Try using demencia lumber. More stronger.

So the radio in my ae86 works but only plays on both front and rear passenger side speakers, the driver side speakers play, but they're very low volume. I know its an issue with the balance knob or internal balance circuit since it can restore the sound to the driver side when i jiggle the knob, but unfortunately i can never get it to stay in a spot where both speakers play. Since i have no idea how to diagnose or repair small electronics I took the radio to an electronics repair shop. After the technician said it'd take $220-280 to fix, I paid the diagnosis fee and picked the radio up. Now I've reinstalled it and the radio turns on, but no sound comes out of any of the speakers. I've found another radio with an actual cassette player out of a supra that i may swap it out for but I still want to keep this radio as a functional spare. Does anyone know where I can find some good DIY books and articles on radio repair?

I've been an automotive tech for 5 years so I can diagnose some things and solder, but im not the best at soldering smaller components, not to mention internal circuitry is usually over my head unless its somewhat simple. Should I even try to repair this radio myself or should I find another shop...?
tl;dr radio has a balance knob/circuit problem and plays on one side with poor volume on the other side, took to electronics shop to get it repaired, now it just turns on and plays nothing. what do?

Maybe just a home-mad satellite that I can send signals in the air. The title is a joke, but I still want to send signals with it. I have: One foot of thin copper wire from head-phones, two old intact phones I don't need anymore, one TV that can't produce light so I don't need it anymore, a pile of hangers, a pile of forks, and sheets of aluminum. Any help?

You could just say 'wormhole'. The general public knows how they work now.
How are you so certain? Isn't it all still unproved theoretical fantasies that might not even work?
>still unproved theoretical fantasies

To you, maybe. To an alien high school student, it's a science fair project.
I imagine they might have something that doesn't require the energy equivalent of all the matter in universe.
>doesn't require the energy equivalent of all the matter in universe

Of course. The energy needed to sustain a wormhole is roughly equivalent to the energy passed through it. If you are teleporting matter, it takes E=mc^2 to keep it open. If you are only passing milliwatts of optical energy through it as a purely communications device, it could be battery operated.

Hey /diy/

I might be moving to Australia in the nearish/mid future and I will have a way of shipping lots of heavy stuff for free like my amps in pic related.

My question is, is it likely possible or approachable to consider rewiring the transformers in the amps to run on 220V instead of their native 110V? Someone was telling me that depending on how the trans. is designed it might not be that hard.

I know I could probably get some of this stuff in Australia but it would be hard to find and really expensive and I won't have a lot of money to bring with me. Also the Audiocontrol stuff is zero chance of finding in Australia.

The main units I'm thinking about are the two NAD amps, if it helps there are a 7175PE Power Envelope (top with the radio station displaying) and a 2155 (bottom with the blank face).

You can buy transformers that convert 11vac to 240vac. AUS industry use them a lot if they buy overseas from the US.

They are external step up transformer units, so I would try to find replacements for the internal transformers on your equipment first though.

If you swap the live/neutral connectors on an AC motor will it run backwards or won't it make any difference because it's AC?
3 replies omitted. Click here to view.
Usually no difference at all. Some disconnects and starters are starting to have safeties built in that won't let the load run if it's backwards.

>And then something something if 3phase is wrong, rotation is backwards. Don't know, not an electrician, I just swap them when I do start up if they are and move on.
>>And then something something if 3phase is wrong, rotation is backwards. Don't know, not an electrician, I just swap them when I do start up if they are and move on.

Three phase is often used for large motors and is very easy to reverse. You just switch two live wires and it will drive the motor backwards.
no that won't work
shaded pole motors will run the other way if you take them apart and flip the windings
cap-run motors can be reversed by swapping the capacitor to the other winding
>cap-run motors can be reversed by swapping the capacitor to the other winding
interesting, thanks
won't make a differece, you need yo inver the stator or the cage to invert the spin of the motor

Damn, Senpai. Now I have no other option but to do it. Thanks for the info AND the motivation!
Made this hand last year.

Sometimes that's all we need :)
That looks awesome

I've been using spray foam in latex gloves and go from there. Yours looks a lot better

I could probably use 4 sets of hands/arms for various props. I like the layered latex method, it would really make some gnarly hands
Did makeup for the skull using paint, latex, and hot glue for the brains. Worm was made using epoxy clay.

Thanks! This was my first time at doing something like this. Took me about 2.5 hrs to make including the paint job. Stuffed the hand with unraveled cotton balls and sealed the end with fake blood. Hardened as it dried so no need for glue outside of the finger nails.
