Neutral's the middle. L1 and L2 are the two 120V phases on the outside.

The ground strap on the middle leg of the dryer connects N to Gnd. In a wiring situation like what you had, that ground connection should have been removed (neutral floats, connected to ground at the breaker box). Black/Red to the two 120v phases, green to ground, white to neutral.

As long as the middle/neutral lead goes on the neutral/ground lug, the two lines don't matter. Either one to neutral/ground gets you 120v for control circuits and motor, L1 to L2 get you 240 for the heater element(s).

Sweet guys, got it all hooked up and working

Wow, a thread was created, conversed back and forth humanly and op was successful!

What the fuck is going on here?

I just scored a gas driven air compressor for $20, However I'm in the middle of cleaning the inch of grease on it and I'm moving the tank around and it sounds like there's dirt inside so I undo the drain valve and there's a shit ton of rust powder that came out (like an ounce or 2 at least) and more inside. I think it's 20-25 gallons, no stickers or anything. Is there any way to
1) clean out the rust powder without rusting it further
2) remove the rust from the walls and passivate the steel
3) make sure im not going to make a 150 psi bomb when I try to use it
The outside has only surface rusting, no flaking or pitting beyond 1 layer or so.

It's not as dangerous as asbestos but still breathing it all around fucks you as well, it might take longer to actually get legit symptoms. I think asbestos sticks around in your lungs longer as it's harder to break down naturally in your body.

What are signs that someone tried to picklock my house lock? My mom noticed today that it was very difficult to put the key in there today, and it was not like that this morning.

>>1178470
If someone bump keyed your lock, it can fuck it up real quick. But youll see that someone slammed a key into it and it nicks up the faceplate.

Kwikset locks can be picked in seconds and arent hard at all to get into.
If someone wanted to lockpick it, they would have gotten in real quick.

In my mind, if nothing was touched or stolen, its probably just a worn out lock.
Nobody lockpicks a house just to take nothing and lock it back up.

I have an old car battery that gives fuck all for current and drops below 6 volts when load tested. I'm thinking it might be sulfation because topping off the water didn't help. This guy claims you can just use a 14-15vac transformer and rectifier to make pulsed DC and it will desulfate batteries provided they're not too far gone.

There's also this one that looks to be a capacitive dropper (and the operation description sounds that way too). He uses different capacitor values to select charging current and he even included a makeshift shunt. He said it's constant current and voltage can run all the way up to 120v+. Wouldn't that wreck the battery?

>Is this legit or bleach and ammonia Crystals tier?

The first pic is the same as common battery chargers before the new "computer controlled charging" chargers of late.

It may help some with slight sulphation but the battery will never be 'good-as-new'
Commercial de-sulfation devices are available and most use very brief higher voltage pulses.
The type your first pic shows would take longer to get the same results if it worked at all.
I'd use one diode instead of a bridge to get a 'rest' period between pulses.

For >>1178636
>Wouldn't that wreck the battery?

The battery "drops below 6 volts when load tested" so it's already wrecked.

When you first connect the device in the second pic the voltage across the battery terminals will be high because the battery internal resistance is high.
Once it begins to charge the internal resistance will drop and the voltage across the battery terminals will fall.
The current limited by the capacitor(s) will drop the voltage to the battery across the capacitor(s).
I'd use only one diode on this circuit too for desulphation. For a charger, I'd use the bridge.
I assembled a similar circuit (without the ampmeter) using an incandescent lamp instead of capacitors.
The current limit was chosen by lamp wattage. (40W ~1/2A - 100W ~1A)

Expect wailing and gnashing of teeth about the dangers involved and how you're about to kill yourself using the transformerless version.
Just be careful. Don't touch the battery or any wires or parts after it's plugged in.
Don't connect or disconnect it or any other battery charger while the charger is powered.
The danger of this is sparks igniting the hydrogen gas given off by charging batteries.

Not very. The azeotrope (point at which you can no longer remove more water from the alcohol) is very high proof but the temps are impractically low. It's not very good at all unless you live up north and you want to go outside to skim ice off of your Applejack at -25. Also you can't separate methanol from ethanol by this method so it can be pretty risky

So I find myself with a lead for free pallet rack beams. I could probably get anywhere from 2-12 for free, any more than that and I would probably have to pay a few cents on the dollar for up to ~100.

I was thinking about using them as raw stock for welding and bolting together to make strong beam for attaching a chain fall too.

Will these work the way I want them too? their ratings seem extremely high for their relatively thin gauge.

Also any other ideas for what these would be good for other than just raw metal beam stock?

any issues with using 100 gallon propane tanks in a 150 psi air system? dude near me is selling 2 for $40 each which is an absolute steal. of course beforehand i would have them tested to make sure they wont explode. i was thinking for plumbing i would turn the tanks upside down and feed them from the bottom so that any condensation would collect in the brass pipes rather than in the tank itself and just put the drain valve on the lowest point of the inlet pipe so i wouldnt even have to drill or weld on the tank itself.

The threads on the propane tank valve are opposite normal threaded pipe/tubing that are used on compressed air systems. I've never seen an adapter for the different threads.

Guy that bought the rusty gas driven compressor here. I'm going to do hydrostatic testing myself because no one in my town does anything other than high pressure gas cylinders. I've read about the pressure washer trick for hydrostatic testing and I'm going to do that. The data plate on the tank says it's rated for 200 PSI so does that mean Duty rated at 200 PSI as in it can regularly take that from the compressor or is that the maximum safety limit is 200 PSI and like a pressure is probably a 150 or 125? I have no idea because there are no stickers or marks on this thing identifying it's pressure or flow. What should be the max safe psi I can overcharge it to to verify its integrity? Like 250 or 300?
Also I managed to pop off the large end plugs and take a peek inside and it's not as bad as I thought, no significant pitting but there is definitely rust more than a layer thick. Dont think it should affect integrity however. What's the best way to wash all of the rust off? Muriatic acid?

>>1178976

Plate ratings, unless otherwise specified, are working parameters. Tank's rated for 200PSI.

Minimum safety factor is usually 2. 3-5 is common. Test it to at least 400PSI.

I got a 1000L hard plastic tub I want to use as a pool during hot summer days. How do I keep the water clean and fresh for at least a 7-10 days? I'll take a shower before I get in and I'll cover it when I'm not using it but I also want to keep it free of algae and mosquitoes.

Wat do

>>1179005
Easy way is chlorine but I don't know how that would interact with the plastic. Hard way is to use a pumping system to cycle the water around through a filter. Hell just keeping the water moving should be more than enough to at least keep the algae away and probably mosquitoes too since they like standing water. Don't even have to bother cutting holes to run the plumbing either, just use some wide PVC on either side of the pool for the inlet and Outle and just run it over the top down to the bottom. If it has a spigot built in just use that for the pump inlet.
Bonus it makes water changes easier, just use the pump to suck out the old water (if it doesnt have the spigot)

Sounds expensive though, I got the tub for free so I don't care too much about it. I'll ask in a pool store for something softer than chlorine, I guess. Thank you.

>>1179013
You can get a decent pump for 200-250, piping and cement will likely be 150 or less, plus the cost of a simple sediment filter and housing. Betcha you could do it all for $400 or less.

>>1179013

One for machinefags:

I need to replace a reed valve in an air compressor pump. I hear blue tempered shim stock is good for this.

But what's the best way to cut it, bearing in mind that it's critical the stock remain as flat as possible to ensure proper sealing against the seats. My current thinking is a dremel with an abrasive wheel and some coolant, but I'm reading that shears would work fine/might be better. I can't help but think they would bend the edges, though.

What is the difference between acetone and naphtha? I'm trying to remove an acrylic finish from a leather bag that didn't quite go on right.

I'm about to buy a $20k house in a nice area of a shitty city. I have essentially no /diy/ experience, but think this house would be a great place to build a foundation. I'm offering very close to the asking price because I really want to house and am afraid of being quickly outbid by an investor if I try to bargain for a lower price. Many nice homes in the city are being bought within the first week on the market.

The basement is the only major drawback as it's covered in wood paneling on top of cinder block and is rampant with mold. I'd plan to strip it all out, bleach the walls, coat with a water-resistant sealant, throw in a de-humidifier, and add soil around the house and adjust the gutter spouts to improve drainage around the house.

Am I being a fool? I can afford to take a loss in the long run, but I've taken such a huge jump into something like this. What are the odds that this mold/water problem costs me thousands of dollars instead of some elbow grease and time? The first floor baseboards stand about 18in above ground level and don't appear to have any wear whatsoever.

>>1179557

Acetone is a specific compound. Naphtha is mix of waste hydrocarbons, usually from petroleum refinement.

Never tried naphtha, but I know acetone is a fairly good solvent for acrylic compounds. MEK (methyl ethyl ketone) is better, but isn't as readily available.

acetone (nail polish remover) is good at thinning/dissolving plastics, especially polyester resins and cyanoacrylates

naphtha (lighter fluid) is more volatile and works well for degreasing and dissolving waxes

How much power does a wall wart draw when idle?
I have to use a little optical DAC to get an audio signal from my ps4 to my speaker system, and it's powered by a 5V wall wart. Ideally I don't want it sipping juice when the PS4 isn't in use, so I thought I could put a switch inline with the DAC power cord, eliminating any idle current draw (from the DAC), but will the wart itself still be sipping energy?

pic related is what I'm using.

>How much power does a wall wart draw when idle?
Short answer : some
Longer answer : depends on the design of the wall wart. Measure it to find out.

If it's a switching wall wart like the one pictured, probably not much.

But thanks for the cue. I hadn't thought to check Amazon. I generally avoid them.

>>1180402
And if its linear, probably not much either.
Old style ' burn' extra voltage, power dissipated is current x voltage dropped so the more power you draw the leds efficient it becomes.
Smps are designed to be most efficient at a certain load, typically 80 to 90 %, at low power it's using the same power to idle as it uses under load, so its a much larger part of the pie at no load and therefore less efficient although the actual power lost doesn't change.

The only way to truly know is to jumper clamp your nips.

I need a good adhesive. I'm just installing a tach on my mini Harbor Freight lathe. I need to glue a flat magnet on to a round shaft. It'll frequently be exposed to WD-40 and Vactra 2. So, nickel to steel, some gap filling, figure 2 inch diameter 5k RPM worst-case for forces applied to it, but I'll be in the line of fire if it fails.

>>1180436
epoxy should work, it has great tensile strength and chemical resistance

make sure you rough up the shaft a bit and clean both parts thoroughly to get a good bond. if the connection does fail itll be from poor surface bonding

make sure its a good quality two part epoxy, and keep in mind that generally the longer it takes to cure the stronger it will be. those 5 minute epoxy kits might cut it but i would get something better just to be safe

>>1180476
Oh, I was definitely assuming some sort of two-pack stuff, probably epoxy, but I was looking for specific suggestions. Like, Loctite 3090 or 660 or something.

In typical residential wiring, does it actually matter if you plug too much shit into a single outlet if it's going to be on the same circuit(breaker) anyway?

I've got 1 PC, 2 Monitors, 1 5-port switch, 1 AV receiver, 2 lamps, and a small fan.

Because I have two UPS (neither of which actually has a functional battery in it) both monitors, the PC, the switch, and the desk lamp going through a single two-plug outlet. It would simplify things if I put the amp on the UPS as well, but I'd like to know that won't cause any issues.

Sparky here. Outlet fires are no joke. They happen more than people think and they're all caused by the same thing. Cheap shit plug multipliers. pic related.

If you plug a high draw device directly into an outlet you're golden. The device (I'll assume is made correctly) and the outlet are rated for the wattage. You plug a high draw device into a cheap plug multiplier so you can also have a clock and a lamp plugged in too then we have a problem. They get hot, melt, short, catch fire, and burn part of your house down.

If you use a decent power strip or a fuses UPS then it shouldn't be a problem.

>>1179490
>I can't get my hands on that

>>1180528
Great, thanks. They're older APC UPSs so I think I should be fine. It's been going like this quite a while, I feel like the amp shouldn't be too big a deal.

While I gotcha here...

A while back, I had a small issue with a power strip (better than the pictured multiplier, probably not by much.) where I had a space heater plugged into it (to extend the reach to a free socket) and I was eating...in the vicinity. Not like directly over it. But a crumb got into contact with the hot prong, and smoldered for a minute or two. The socket on the powerstrip was a little warped and scorched, and to my surprise, the socket on the wall that the power strip was plugged into was also a little bit scorched.

So, is that socket off-limits now? The entire outlet? Or would I have seen a problem with the wiring by now just because it's on an active circuit?

>>1180533
I would replace any warped outlet and throw away the melted power strip. Outlets are so cheap. 50 cents for cheapos and a buck for good quality. No reason to risk it.

In the mean time if it is just one socket on a duplex outlet that's warped I wouldn't have a problem using the other socket of the outlet.

>>1180537
For a layman is replacing a duplex outlet a simple swap? Turn off the circuit breaker, of course. Any particular hazards otherwise?

My concern was more for the wiring in the walls. Does it have current running through it even with nothing plugged into that outlet?

>>1180539
>Does it have current running through it even with nothing plugged into that outlet?
If you turn off the breaker you are fine. Do that.

As soon as you touch a live wire/outlet and you are grounded YOU are the thing plugged into an outlet. That why people get shocked when they do stupid shit like stick a butter knife in an outlet or something. You become a path for the electricity to travel along. Same thing will happen if you accidentally bridge the live and neutral wires. Even professionals that do 'hot work' make mistakes and get killed every now and again. An amateur should never do it.

>>1180539
Replacing an outlet is pretty simple. The wires are screwed or pushed into the back of it. Unscrew them and move them to the new outlet. I'm sure there's a million youtube vids for it.

The wire in the wall should be fine. The only way a melted outlet can hurt the wire is fire. The outlet in question might have current running through it with nothing plugged in if it is in the middle of a circuit and you have something drawing current downstream of it. Even then the outlet would have to be deformed really bad for the internals to short out. If that happened the breaker should trip.

A lot of outlet melting/fires happen because bad electricians put shit 15 amp receptacles on 20 amp circuits. Spent the extra 20 cents and get a 20a rated outlet.

>Spent the extra 20 cents and get a 20a rated outlet.
20 amp outlets often have a different socket type. Picture related, NEMA 5-20. If you put a 20 amp outlet on 15 amp wires someone might think it is rated for 20 amps and overload the circuit. Best case this will trip the breaker. Worst case it will cause the wires to overheat and start a fire.

Do not put NEMA 5-20 outlets on a circuit unless everything else on the circuit is also 20 amp rated. Wires, breakers, and even other outlets.

False. 210.21(B) of the NEC allows 20a receptacles on 14 awg/15a branch circuits since the over current protection device will protect both the wire and receptacle. This is called derating and is done all the time.

Alright /diy/, I built a solar panel and fully enclosed it permanently but I accidentally hooked up the individual cells in parallel which resulted in 2 volts at 20 amps. I was planning for it to have 12 volts of electricity so I could hook it up to an inverter and have usable electricity. Any ideas on how to increase that 2 volts to anything usable? I've checked out booster circuits but I couldn't find 2 volt input ones that can handle 20 amps. Also, I have 0 electrical engineering experience. Any help is greatly appreciated.

>>1181025
The voltage is too low to do anything useful with.

I spent 10 minutes looking at mechanical oscillators and voltage multipliers.

The thing is. The forward voltage of most diodes is higher than the solar panel output. A 555 timer requires 4.5v.

You can't even get a PWM signal out of it to use in a DC voltage multiplier.

>>1181047
Damn, the panel is already enclosed so I can't reverse hook them up into series. I have a bunch of these tiny garden lamp solar cells which produce a good 10 volts if I hook them up in series only problem is that they produce only .03 amps of electricity. Would it be possible to use that to do something?

>>1181025
You could try a mechanical oscillator to give you 1vac or 2v PWM signal

Then run that through a very efficient Walton cockroft voltage multiplier that uses Schottky diodes. I'm unsure if the voltage is high enough for it to work.

>>1181051
Wait. You could bulk charge nicd or nimh cells with it.

>>1181025
U dun goofed, 2 volts is far too low, you'll loose a fuckton of energy in the process, create 5 more panels and put them in series, kek.

>>1181056
that's not very energy efficient

>>1181051
Nicd and nimh cells have a max voltage of 1.5v.

Can't really think of what else to use 2v for.

>>1181058
Doesn't matter if you are using solar panels anyway. What else can you do with 2 volts anyway.

You could use it for electroplating too.

>>1181025
>>1181051

No. You misunderstand the scale of solar panels. To get the power that just one outlet in your home (120v 15a 2.4kw) can output you'd need around 12 200w solar panels. Each 200w panel is 5.5 ft by 3 ft. Extrapolate that out and you'd need 60 feet by 36 feet of panels to get that 2.4kw. Your panels will never produce enough power to be useful.

>>1181025
You could use capacitors and switch them between series and parallel.

Example, wire 6 capacitors to a lot of relays so they are connected in parallel to the solar cell when the relays are off and in series with the output when the relays are on.

>>1181069
I already know their scale, I just want to charge my laptop for free.

I'm talking about the screws/bolts that, once you unscrew them fully from the bottom piece, they kind of "hang" in the top piece but can't fall out.

Im looking at a project with modular pieces and it would be cool to implement these with bolts on the modular pieces so that we don't have a few dozen bolts to fully remove, we can just zip them in and out when we need to, but I can't for the life of me figure out what this method of securing the screws is called, so I can't find out "how it works" to replicate and use it.

I got a problem with my toilet. After flushing it it makes this loud ass foghorn-like sound and won't stop unless you turn off the water valve in the back of the toilet. I researched the problem already but nothing I've found assesses the problems I'm having.

First thing it said was to lower the water level in the tank. I lowered the float on the fill valve and then let some water out from the tank by flushing. The water level rose back to where it was before adjusting: to the overflow tube. I'm looking some shit up now and it seems like I need to replace the whole fill valve. Before doing that I want suggestions on what could be the cause of the problem.

If it helps, it sounds like the noise is coming from the overflow tube.

>>1181356
>After flushing it it makes this loud ass foghorn-like sound and won't stop unless you turn off the water valve in the back of the toilet.

My guess is "water hammer".

It happens when pipes aren't secured to the framing of the house and the water flow and length of the pipe form a resonant frequency that vibrates the pipe.
Depending on how the plumbing is laid out you may be able to add a 'shock absorber' to the line.
It's just a cylinder with air trapped inside and the water cushions against the air when it tries to hammer.
Try adjusting the stop to a very slow refill speed. If the water isn't rushing in it may not be able to generate enough force to start the vibration.

>>1181307
>>1181333
>Captive.
This. There is an area under the head of the screw that has no threads and is slightly smaller in diameter.
When you start removing the screw it doesn't back out through the cover.
Some applications have a circlip or washer to make it even more difficult to get it back through the cover.

>>1181364
The top will offer greater oppertunity to actually find and use the blocking...

>My guess is "water hammer".

That's not water hammer. Water hammer is a slow, decaying "thunk...thunk...thunk..." in the pipes. My bathroom faucets do it whenever they're shut off. What he's describing is a problem with the fill valve. It's not shutting correctly, and it's sitting in such a way that it's acting sort of like the reed you'd see in a wind instrument.

As such:

https://www.youtube.com/watch?v=MIgMeyW4TEM

It's not uncommon for it to happen briefly as the valve is closing, but, if it doesn't stop, you need a new fill valve.

Hey qt-dot

Is there a major difference in psi gauges? I smashed the one on my craftsman 919167370. I tracked the part down to a guage called D21929 but its $37-44 each. That seems outrageous for a 300psi guage and i can find similar from other hardware stores for <$20. I don't like cheaping out on chinkshit. The craftsman air compressor is just a rebranded DeVilbiss and made in merica, but i somehow doubt this guage isn't just chinkshit

>>1181474

>>1181538
>You think there could be any other cause? I'd really like to try out all possibilities before going out and buying a fill valve.

Can't think of anything else there would be. Technically, it could be the shutoff, but it would have to be nearly closed for that to happen. It'd be pretty obvious if your tank was taking 5+ minutes to fill. The only other restriction in the line would be the fill valve.

can someone give me a quick rundown on how carburetor pressure boxes work? i have a little 212 predator i want to smog pump supercharge and rather than getting a blow through carb you can just enclose it in a box and it makes it work correctly without blowing air up into the carb. im just having a mental issue figuring out how something like that even works (it does work, people have done it on small engines and normal engines since the old days of forced induction).

>>1181474
>Is there a major difference in psi gauges?

As >>1181487 pointed out, the only things that really matter to a pressure gauge is what you're measuring (liquid or gas), its measurement range, and what kind of fitting it has on it.

As long as your replacement gauge is of the same (or greater) range, made for compressed air, and has the correct fitting (or you can get an adapter), then it'll work.

The desks they use to put the computers on that the staff use for stock control aren't.
Pretty much everything else is.
There are some things made of ' solid' wood but its really thin knotty pine seconds and its usually very poorly sanded and painted with a garish stain so you can still 'admire' the 'finish'
Don't be fooled, a good particle board desk will stand up to punishment better than a cheap solid wood one. And it will cost a fraction.
Try jumping on it on the store, that's what its there for

Rotation has little to do with flushing ability. In fact, those older units should never have an issue simply because of the sheer amount of water the throw down the pipes. What you likely have is a partial blockage. Everything works fine until something gets suck in the partial blockage but it clears itself without becoming fully blocked. A plunger wouldn't help in this case. Snake your line and see if that helps.

strange question but I don't wanna shit up the board with a thread, in fact I am not sure I am allowed to ask being as this is a blue board, mods feel free to remove this.

what is a safe finish to use on a wooden sex toy?

>>1182657
What kind of sex toy? I wouldn't consider anything wood to be safe for insertion due to its porous nature. Get some platinum cure silicone, either formed and cured into something you like, or a diy mix so you can do your own. You'll need a light vacuum chamber for the latter, for removing dissolved air that would make bubbly imperfections.

>>1182665
Glass, surgical steel, and some plastics are also good.

>>1182665
I've heard wood has been a commonly used material for a long time, but the porous nature is exactly why I ask, as it would certainly need some kind of finish. the reason I am more or less set on wood is because I don't have a lot of tools, and I have no experience with glass, steel, plastics, ect. but I have done tons of wood work, just, no wood work that needed to be safe inside of a human body.

>>1182690
>>1182657
Carve your wooden dildo and then use it as a master to make a mold for casting silicone.

>>1182690

http://dangerouslilly.com/2014/04/wood-sex-toys-introduction/

I'd go with platinum silicone. Lasts a lifetime with no maintenance. Only tool it needs that you don't already have is a vacuum pump and improvised chamber, and that's optional if you don't mind tiny flaws. Only downside is incompatibility with silicone lube.

>>1182693
I could do that, but I don't really plan to produce multiple, just one, so I don't have much use for something like that, though I just got an idea, is there possibly some way to coat wood in silicone?

>>1182699
There's really no good raisin to encapsulate rotting tree carcass inside an inert material.

>>1182699

>>1182703
okay, let me put it this way, I am a dumbass set on the idea of wood or a wood like material that can be shaped similarly, what would be the best way to make rotting tree carcass safe for the human body? or if you have a material that can be shaped similarly to wood that's affordable, what would it be and how would/should I seal it?

>>1182710
What shape are you going for? A generic phallus, indistinguishable from others you can just buy?

>>1182713
not even sure yet, I figure its a colossal waste of time to make an idea for something before you know how to do it correctly and safely, I'll probably spend a few more days autisticaly scouring the internet for information on how to do it and improve the final product. if I really cant find a way to make wood safe, I'll put it off a few years till I have learned to cast metal (and honestly I'll replace the wood with metal in the end anyhow, but id like to learn what is good and bad shape speaking with something easier, like wood.)

>>1182718
>waste of time to make an idea for something before you know how to do it correctly and safely
isn't it the other way round anon?
researching the best manufacturing methods before you even know what to make sounds pretty retarded imo

>>1182718
I don't think casting is how anyone makes quality metal toys. It's all machined from bar stock. You'd need to do that anyway to get a good finish.

>>1182721
well, its not that vague, its not like- oh I want to make something from bronze one day lets learn everything about bronze, its more- I want to make a ring one day, lets learn everything about making rings. I learned to be this way after screwing things up as a child (likely because I was a child) and getting told it would have turned out a masterpiece had I just spent a few days researching how to do it.

but that's not here nore there, I just wanna make a wooden woody without killing anyone.

>>1182723
Could always hand polish it very slowly?

>>1182723
don't really have much in the way of machine tools as a whole, just a small belt sander. the rest will be all done by hard work and hand tools, and lots of sandpaper to finish It off smooth. I've done a lot more complex jobs with a lot less, just takes time. besides, I'm at least hoping it will be romantic.

hell that's the whole idea for why I started thinking of this project, I could always just buy any old dildo, but making one seems romantic

>>1182728
Cyanoacrylate is probably reasonably safe, it was originally used to glue wounds. Something like 8-20% of the population CAN build up a negative reaction to it, but I believe that's only in the uncured state. Any type of food safe coating should be fine as well, such as salad bowl coating. Whatever you choose, just give it extra long to cure, in as ideal an environment as possible (probably just somewhere warm with airflow), because it's usually the uncured state that is a health issue.

>>1182736
sounds good to me, and obviously if there's any adverse reaction we will stop use immediately

>>1182743
Well, double check how it works, because CA glue is super-glue, so it's super common and handy, you don't want to be allergic, it sucks. It's also not something that really goes away once you have it.

>>1182744
damn, well I may have had a minor breakthrough, raw flaxseed oil is food safe and apparently sex safe, but I actually tend to use it on knife handles because it cures hard (though it takes many days to do so) like linseed oil, without being toxic

Oh, neat.

>>1178858
How could I buy one or two of these racks from you at a really great price? :D

flax and linseed are the same thing. The fibers of the rest of the plant get made into linen. But don't eat linseed oil that isn't food grade. Better not to eat flax oil either. Oxidizes fast. Get some whole flax seeds and grind those and put them in whatever. Good for your heart.

could stove coils withstand being heated up to 1300-1500f on 240v? trying to make an electric aluminum melting setup and if these would work it seems a lot easier to set up that with nichrome/kanthal coils

>>1182766

I highly doubt it. Stove coils are made with a resistive wire inside ceramic insulation inside a metal tube. In order for the outside to get that hot, the wire itself would have to be far hotter. Don't know exactly how much, but I'd guess enough to melt it, or at least break itself/the ceramic insulation quickly from stresses induced by thermal cycling.

Making your own coils is easier than you might think. I just made some for an electric furnace I'm working on. I have a lathe, so it only took me a few minutes to turn 100ft of kanthal into a very professional-looking element. You can do the same with a drill, a metal rod, and a simple jig to hold it up.

>>1182773
Damn. What about the large ones for inside the oven Or some story then? Main reason I would rather not use coils is just that it would be kind of a pain to actually install and hold them inside the furnace.

>>1182775

They work the exact same way, just a different shape.

Since you're just doing aluminum, you could just use some stainless wire bent into hooks and stuck into the walls of the furnace.

Otherwise, just buy a small quantity of refractory mortar (or furnace cement; most hardware stores will have some in the HVAC section) and mold some supports. Wear gloves; a lot of high-temperature mortars use sodium silicate as the binder, which isn't good to handle.

>>1182779
Figured. I guess if I have to use coils I'll just do it the proper way cutting a spiral channel in firebrick.

>>1182781
>I guess if I have to use coils I'll just do it the proper way cutting a spiral channel in firebrick.

I can help you there a little, maybe. If you don't want to fuck up your power tools with ceramic dust and make a god-awful, cancer-inducing mess (or you just don't have the tools in the first place), glue a strip of coarse sandpaper (think I used 50 grit just because that was the lowest I had, but the coarser, the better) to the edge of some scrap plywood/MDF. Doesn't take as long as you might think. Took me an hour to do 5 grooves in a spiral pattern through 10 2600°-rated bricks. 30-grit (or even lower, if you can find it) on 2300° brick would go quite a bit faster, I imagine.

I have an old army jeep that operates on 24v.
Said jeep has mil trailer plug on the back.
Have an old mil toolbox and newer 12v cb and head unit.
I want to put another trailer plug on toolbox, mount cb, hu, and power inverter inside the toolbox possibly with a 24v-12v step down for the former two as the inverter could possibly be quite a bit of draw.
There are no aux power lines to the trailer plug on the Jeep side, but there are unused ports in the plug. I believe the Jeep wiring is 10 gauge though I could be wrong. The terminals in the trailer plug are brass. If I ran 4x 10 gauge wiring through the trailer plug, what amperage at 24v could I pull before overloading my (trunk wires?)?
I'm trying to size (in wattage) my inverter so I can research which one I want and size (physical) everything out in my toolbox.
I'm after modern amenities/accessories housed in something that looks somewhat period correct. I would also like it to last as long as possible because I'm redoing the Jeep at the same time and I'm hoping to get 50+ years out of it. Any heavy/extreme duty component you know of that would work for my application please tell.

Im starting a 3 month trial as a landscaper on monday any tips. first time on a construction site

>>1182793
Don't use a fucking inverter numbnuts. Military vehicles have two 12v batteries. Just hook your junk up to one battery and you will have 12 volts, no inverter required. Inverters waste a lot of power and you shouldn't use one if you don't have to.

>>1182812
Those 12v batteries you speak of also need to be treated as halves of a 24v cell, no tapping one of them.

Why is tempered glass so expensive but companies like Ikea can make entire display cases for the cost of a single piece of 1sqft tempered glass.

Not a question, but I wanted to share something stupid I did today. I needed a 15' (5 metre) RCA cable, but didn't want to buy one, since it's obsolete tech anyway and I just wanted to keep my retro NES. Turns out that braided outer layer that's supposed to reduce noise is entirely unnecessary; I spliced the RCA ends onto some old 15' phone line I had lying around and it worked great.

Tomorrow, I'm going to build a couple RCA>RJ12 cables, and run my TV's video out through the house to mirror the screen to a TV in the kitchen. Wish me luck!

>>1183239
That's pretty lolleriffic, but what you did kinda makes sense. You traded a coaxial transmission line for a differential pair. But phone line is 600 ohms vs probably 75 for video so it's not ideal.

>>1183240
>But phone line is 600 ohms
That's the impedance a telephone is supposed to see, but the impedance of your typical telephone cable is much lower, around 100 ohms.
Not that the cable impedance matters at audio frequencies.

The back of my house has a potential man cave hidden at the back of the garage. The previous owner did a rather nice job of making it usable for storage but I'm curious if anyone has a better suggestion for turning it into living space. The wall to the right is part of the back of the kitchen and cloak room. The only real issue at the moment is that I'm too tall to stand on the lower decking but lowering it further would reduce the usable space.

>>1183313

It's plenty stronk, design-wise. The board across the back prevents it from racking on one side, the tensile strength of the plywood resists racking forces on the other side, along its axis of strength.

The main weakness is the lack of corner braces or L-brackets and probable shitty joining of the steps to the back piece. Plywood should never be joined exclusively at its ends.

Step sizes are wierd but I guess since your only using it a few times a day it's alright. I would poly the treads so they don't get super dirty over time (you can just wipe them clean if you have a coat of something on there)
The vertical boards I would worry about, assuming you just rammed screws in the bottom of the board (the weakest way fyi) you would need more strength to assure nothing goes wrong ever.
I would suggest a single L bracket below each riser. (Bottom left for a total of 4)

I'm refinishing the reflector panels on my solar cooker. I need to bond aluminized, non-stretch polyester (Coghlan's Emergency Blanket) to weathered aluminum foil.

I have Devcon 2-ton Epoxy and JB Weld. I doubt either will work for this. The aluminum foil is bonded to wood using wood glue. The emergency blanket is slightly transparent so having the aluminum foil under it will help with reflectivity.

Any suggestions on what bonding agent to use?

>>1183542
Who will be controlling it? People at the top and/or bottom and/or the people in the cage? Controls can be all 3, but if you want something specific...? Buttons would be the way to go. One for up, one for down, and one for stop. Onboard controls allow people to control it who are inside. Controls at the top and bottom allow people to load it with cargo and use it without people onboard.

May be the best to use if it will setup being sandwiched between foil and blanket where stuff won't dry out for a long long long time. Plus, it will be a bitch to lay the emergency blanket on it and smooth out wrinkles if it is instantly tacky and doesn't sheer well.

Applying it in small strips and rolling the blanket onto that section may solve application issues. Only that stuff costs nearly $30 a can.

Imagine the AC signal. +, 0, -, 0, +, 0, -, etc.
Now full-wave rectify that.
+, 0, +, 0, +, 0, +.
Shove that across a cap to filter it.
Because it's full-wave rectified, you're getting more than Vrms since you've flipped the negative cycle positive. But because area under the curve, you're getting less than Vp-p.

>>1183895

whenever you have coils and capacitors in the same circuit, some magic properties can pop up, like more current flowing in the coil than is coming out of the socket, or voltages higher than you would expect. ignore it if you wanna stay sane.

I measured it in parallel with the cap.
I replaced the capacitor the other day because the fan wouldn't start and I was trying to unwind and go to sleep and not dick around with shit, and just haven't made a proper splice yet.
Where the capacitor is wired in, the wires are still exposed and that is where I put my meter.

Since it is parallel and not series, should the meter really be seeing rectified stuff? It was in ac mode, dc mode didnt show any voltage (since its still ac current)

>>1183922

ignore the dude above, he was just guessing. wrongly. the entire fan circuit is 100% AC. the apparent high voltage is due to resonance.

Just to clarify: There is NO WAY for me to clean a set of windows where the condensation has built up and dirtied inside both panes, right?

Your windows are broken.
The panes are supposed to have a vacuum or an inert gas like argon inside of it to prevent heat transfer to or from the inside.

Contact the window manufacturer and tell them "shits fucked yo" and see if they will replace them. Some will warranty it.

Parents just bought another house and they noticed the condensation bullshit going on in 2 of the shit ton of windows. No info about them at all besides the company name. Called them up and get them replaced for free, even have the same paint scheme.

I did.
Thought about doing that as I'm working with 32cc engines and it would be less power loss, but the whole thing is on hold for more important stuff.

That's fucking interesting. I'll have to give them a call.

If youre the dick that drives by at 2 am every night without a muffler on that thing, fuck you.

Oh, no, not me. Mine never truly came to fruition, although I still have all the pieces and may finish it someday. I get sidetracked with life and new projects. Also, the weedeater-bike is unfortunately on the list of things that I'd like to get done, as opposed to things I need to get done.

yea I figured it wasnt, but a part of me is hoping the faggot reads it too

i need some brake/clutch like friction material to test a small homemade go kart clutch. im thinking skate grip tape, but im sure there is something better. only catch is it needs to either be on amazon or in home depot/lowes because i live in alaska and dont feel like paying an assload in shipping if it will even ship at all.

Thanks, put it up last night and already gone.

She talked me down to $450 though because the top wasn't flush.

how do i pound out this axle stub? its seized in the bore with rust. ive tried pounding it with a 5 lb sledge, soaking it overnight in pb blaster, and pounding it again but it wont even budge. i would really like to avoid mushrooming the stub because that will make it even more of a pain to get out.

Heat the hub with a torch so that it expands and then blast the metal part in the center with upside down canned air or ice or something so that it shrinks?

Does anyone know a good place to buy small wooden (or maybe metal) alphanumeric letters for cheap. Preferably with font and size options, and the ability to buy individual letters. Anywhere from 1/2 inch to 1-1/2 inches tall.

I need to make a sign.

I have an old worm drive that's never had an oil change. Everything online says to run kerosene in it for a minute to flush the old shit out, but I know how the US is with not really having specific repeatable names for petroleum based shit(naptha, white oil, kerosene, etc), and since what I know is made for burning, I figured maaaybe I'd just ask you guys before I fill a gearbox full of flammable stuff and heat it up. Is https://www.lowes.com/pd/Crown-Kerosene-Heater/1000148047 the right stuff?

>>1178092
in the wise words of uncle bumblefuck, do NOT fuck with pressure vessels. buy a new one and swap it into the compressor. could it be fine? yeah, but how much do you value your life and that of those around you?

>>1184815

By "heat it up" you mean slowly rotating the worm drive? I don't think that will generate nearly enough heat to ignite kerosene.

>>1184815
>the right stuff?
Yes
I've done this to engines with so much sludge they wouldn't operate properly.
Half oil - half kerosene.
Let run for ten minutes.
Drain and replace with fresh oil.
Use/drive vehicle for a short while.
Drain and replace oil once more to finish up.

For your saw just dump what gearbox lube in in there and fill with kerosene.
Run it a minute or two but don't load it by trying to cut anything.
Dump it out and refill with gear lube.
After you've used it a bit change the gear lube one last time.
