what's the wattage
give me something other than 100 people to describe the room.

>>1155565
Dance floor is about 10' by 12'. Don't know the dimensions of the whole room. But the speakers will be right next to the dance floor.

is the room really reflective? does sound bounce around easily? or is it in a room with plaster walls with a carpet?

>>1155495
Doesn't sound immediately cost-effective (or possible) unless you have a connector issue.

Good thread

>>1155495
what about it?

Soaps are easy as fuck. Soapcalc.com is your handy dandy tool for lye calcs.

Lye is hardly the most dangerous thing you can handle. Just don't be a retard and hold the lye water over your face to see if its all dissolved or shit like that. Wearing PPE will put you well ahead of every single grandmother with dementia that still makes soap in her kitchen.

They say always add lye TO the water and not the reverse, but no one's ever documented a case of it supposedly going batshit crazy like its supposed to. Fuck Ive had bigger reactions that made me piss myself from adding baking soda to hot vinegar. Never ever add lye to hot water.

Body washes and liquid soaps are more difficult, require potassium hydroxide, and are much more involved than bar soap.

That being said I make a spray autobody cleaner for my brother's detailing business that he resells for exorbitant prices.

I'm a chemist and much prefer handling acids but sodium and potassium hydroxide aren't that nasty or hard to handle. You use sodium hydroxide for solid soap and potassium hydroxide for liquid ones, generally. You want good lab goggles and nitrile gloves with the slightly longer cuffs than the typical kind, maybe a plastic apron as well.

Wear clothes you don't mind damaging, lye drops don't leave an immediate spot on fabric but a hole will appear there when you wash them.

It's annoying to dissolve the pellets in water, you have to do it slowly (it makes a LOT of heat) and can't use glass containers (it etches glass), you want to only use polyethylene or polypropylene (HDPE or PP) plastic containers to dissolve it in. Usually I mix it outside for ventilation.

An immersion blender is really handy for actually reacting the oils and lye to speed up the process (it can take a LONG time). No real suggestions on what fats to use, there is a ton of info and opinions on that. I've used various mixes of olive oil (takes a while to cure compared to other oils), grapeseed oil. coconut oil (don't want too much of this in the soap or it messes with the feel of it, a little is great though), cocoa butter (too expensive to make into soap, I think) lard, and bear grease (basically similar to lard). It's pretty efficient, you get a lot of soap out of one batch, just takes a bit to make.

>>1155471
Right on man. Any advise for making my own car wash?

I havent made soad yet but i have made some candles and bought shit to make soap.

Having hell finding a good silicone mold. Probably gonna have to make it...

>>1155036
not being rude, but theres a gardening thread on /out/ that has a bunch of really knowledgeable anon's in it.

go peep that.

Want to increase pH (to make it more alkaline), use any form of hydroxides aka Lye, Ca-Na-K-OH
A practical way to decrease the pH is to use compost, specially homemade compost, all the starches and sugars are fermented and made into acetic acid (vinegar) which is in turn a weak acid and a better option than dumping car acid battery on the floor.

>>1155036
see
>>>/out/979331

Also, use google. You also should not raise or lower the pH quickly. It needs to be done over time over the course of a year at least.

leaf springs?

>don't have a forge or hammer
>kind of quenching or hardening process as i don't have a long container and fill it with motor oil
jesus, you may as well buy a sword off late night tv

>>1154295

Yeah, if you want a functional sword you're going to need to harden and temper the blade. If you want to go this route, you might use a high carbon steel like 1084 and send the blade out for professional heat treatment. The best way to diy the heat treatment would be to dig a little coal forge in the ground with a hair dryer taped to a buried pipe for your air supply. Heat the blade evenly until it's no longer magnetic then just a few seconds longer and quench in oil. That'll harden the blade. Then you're gonna need to find an oven big enough to put the blade in to temper it. If you just want a decorative sword look for some cheap stainless and don't worry about heat treatment... but also make sure you never hit anything with it.

>>1154304
hmmmm, i can make a coal forge using some bricks honestly, its a construction site as i said, would that work? also in the regards of professional heat treatment, finding one that is decent here is almost an impossibility, most metal workers here do shit like balcony fences and aluminum sliding door frames, finding a guy who knows the baby steps of hardening is well, hard.
so i can get a pipe long enough to fit the blade length, and i can use the forge to temper the blade, now what kind of oil do i use?

>>1154183
>I'm planning on heating it to give it a slight curve
Are you mounting it to something? Like making the radius and bolting it down?

>You can heat it, but heat it slowly or you'll discolor it
>It dulls blades a lot faster than wood
>Don't use a cut-off wheel without a guard and gloves. It melts and sprays all over.

When I use it for work it's usually as wear strips for moving machinery. We cut on a table saw and mechanically fasten it to the piece. We never had much luck heating it. Also it doesn't deal with UV real well and cracks develop over time, starting at the radius.
Sorry I can't help more, we have limited uses for the product where I work.

>>1154183
It doesn't take a lot of heat to melt, literally a couple of minutes in the oven under 200C and its quite bendy

>>1154200
Couple of flavours are UV resistant, majority arent

>>1154200
I'll be painting it so discoloration won't be a problem.
>Don't use a cut-off wheel without a guard and gloves. It melts and sprays all over.
Lots of plastics seem to do this. Thanks for the heads up.

pic of the upper spindle bearing

the brand is "RIFU" wich sounds sketchy

but the installation just screams china quality

pic related, yes those are fucking hammer dents on the cover plate of the bearing

I have heard, but not confirmed, that moly is actually too low friction for bearings, as it causes them to slide, rather than roll.

An NLGI No. 2 grease, such as a wheel bearing grease or multi purpose lithium grease for your car. You don't need anything fancy as it's not exactly a heavily loaded application, nor do you need it to be waterproof. Typically it is a light amber colour.

What disgusting metal is that made from?

>>1151564
Never brought anything, but I have seen arc welders in there for £60 before. Tbh it sounded too cheap to trust

>>1151564
Bought an angle grinder and calipers from there years ago for super cheap that are still going strong.
That said I also once bought a biscuit joiner that started falling apart with springs shooting every where as soon as I took it out of the box.

I think the more rudimentary and simplistic the tool, i.e. the less moving parts it has, the more likely it'll be actually usable.

>>1151564
Some are good, some are not. I have an angle grinder and a caliper and they work fine. Tried a drill press, and it was just a piece of crap.

>>1151084
replace all body panels with scraps

the more patchwork the better, ideally the whole thing is just niggerwelded together with zero original panels

i imagine touching any of the actual mechanics would be no good if you are going for cosmetics

Well if your going for form over function dont forget foam and latex can look sharp and pointy.

Old thread reached bump limit

Might want to include Fritzing in the layout board software section. I don't use it much personally, but it is free and very user friendly.

>>1151155
Apparently it's at its character limit, hence the thread link coming afterwards.

You forgot the dash between "/ohm/" and "electronics general".

Buy one

The idea is that I want to see if I can make one, dude

A legit spacesuit would be very hard to build. I'd say that your only option would be early space suits, like the ones from the Mercury missions.

Space suits are made from many layers of different, and quite expensive, fabrics.

It's a very cool idea. Do you have any rough plans on how you would go about it?

>>1156876
Carburetor bolt has those as a bushing. There's a pair, one stuck in the bolt, the other fell off and you got it in hand.

If not the carb, something else, it's definitely a bushing for a bolt. Hold ot up and compare its size to bolts you messed with.

>>1156881
Actually not even the carb. I meant the air intake for the carb. my lawnmower looks just like it.

looks like an alignment dowel. it's the kind a bolt passes through.

Porcelain tile isn't bad for rentals. I use it as much as I can. You just have to make sure the subfloor is solid. If it flexes at all your tile will break.

>>1156860
Will it hold up to outside use, rain, sun, freezing temperatures?

The slate lasted like 10 yrs. it wasnt thick slate though

>>1156862

Yeah, you'll just need to reseal the grout as needed. I aim for every three years, but I've gone 5 years without a problem.

What kind of subfloor do you have?

>>1156713

When you're cutting it off, avoid sensor lines or anything like that. Make sure it isn't going to drag. Make sure it isn't going to touch anything that it shouldn't. Don't set yourself on fire with any nonsense around the fuel line.

Pretty obvious and simple stuff. You won't see much performance gain on an engine from 3 inch unless you're pumping a lot of air ie. 450+ hp. See the engine masters episode on it. Although there's not much point in not going 3 inch.

Strait pipe it pussy.

>>1156713
Flowmaster makes pipes for those things that are less expensive than buying shit from Napa or wherever you'd buy new pipes. Used to have benders and shit for making exhaust at my work, but stopped doing it because the pre-made pipes got cheap enough thay making them is a waste of time. However, the pre-made ones are shit quality, and sometimes (a lot of times) the flanges and shit are welded on wrong. The flowmaster ones would be better quality, too.

>>1156713
Search some exhaust threads on crownvic.net and pantherbb.com. I've heard that the 16v 4.6 needs some back pressure to run properly with the factory tune, so increasing the diameter of the exhaust may decrease performance. If you just want to fix your exhaust, cut out the bad sections and put in new pipe using U-bolts. If you don't have to pass inspection do the same with the resonators and mufflers to make your land barge sound like a bro dozer.
