Second.

If its very very old, there might me some metal supports inside you can scavenge. Newer models are all plastic, though.

Looks like there might be some mediocre speakers in there too.

This is how I know its out of your league. Motors aren't something you cut up and cobble together. Different solid fuels have different energy densities and firing characteristics, not to mention proper packing, wadding, and curing.

If you want to blow your face off, that's entirely your business, though.

I made a few hundred bucks under the old alchemy system. Couldn't make a living off it, though.

OP lives in an area with sub-freezing temperatures. Nothing but neglect would lead to straight water cooling, though it is done intentionally in certain circumstances.

Be sure to write that somewhere on your body away from the blast area so they know what the fuck was wrong with you.

Sabatier device, bro. Converts CO/CO2+H/H2 into methane and oxygen. I'll probably settle for a H2 input to simplify things.

>>126708
Antifreeze actually comes in green, yellow, red, and orange. If the previous owner didn't give a fuck flat out, it might be mostly water.

>>126690
Tastes pretty sweet. You'll also go blind if you drink enough.

>>126678
Awwww shit.

I'm working on a closed loop sabatier device design. Hope to run a prototype in the second sleeper on the truck I might buy tomorrow.

Email me or something if you're interested.

Scratch what I said about rose oil. Didn't notice you did a beeswax dip.

I usually patina and quench in ATF for decorative work like this. I'll have to look into beeswax, because I'm pretty pleased with what it did for the texture and sheen on this piece.

I had a feeling you either didn't use mandrel shaped pliers, or did and had no idea what you were doing.

I think you did pretty well for what you were working with. Could've opened up the petals a bit more with some proper pliers, but you didn't have the tearing and angles one would expect from square jaws.

Also, protip from a few old masters that've been dead for a few years.
>rose oil
Put that shit in there. Just a drop per bud should do.

Took me a minute to understand what I was looking at. Nice work. What do your round nosed tongs/pliers look like?

Taste it. Dollars to donuts its coolant. Check your brake fluid/power steering fluid reservoir. Neither holds much more than 20oz if that, so if it was one of them, they'd be bone dry (assuming you ever had them topped off in the
first place).

Pinzfag? Is that you, br/o/?

I use a lighter and an old piece of denim.

Just light the insulation on fire, blow it out when the desired length is burnt, then wipe off the charred/melted plastic between the two folded over sides of denim.

For smaller wires, you can take a fine grit sand paper, fold it in half, grit on the inside, place the wire in it near the crease, pinch through the paper to hold the wire, then pull it out with your free hand. Might take more than one attempt.

Ask about the pallets. Low volume retailers can't afford the space to stack an entire truckload to sell back to a pallet company.

Anything left in the parking lot of a truckstop is fair game.

PC? He's hooking it up to a computer?

Inline fuses and diodes can help keep things from going horribly wrong.

Audio input jacks don't really carry much power, and most loose wires floating around in a PC are 15.5VDC at most on a very bad day.

>>125128
Yeah, that's the technical term for it.

I haven't done any detailed iron casting yet. I don't think I'm up to 14" gears and 35lb posts yet.

I'm terrible at hot punching without an assistant, so a blacksmith's post drill is the easy way out. Used to see them going for about $80 before iron prices shot up again.

>>125138
I'd trim and strip those wires while I was at it. Fraying will reduce the mechanical strength leading to a premature repeat of this scenario.

>>125113
Yeah, i'd like to have an oven for smaller stuff. POR-15 dipping can only do so much, and its pretty expensive.

I'm working on a 3 axis CNC myself. Lost a few pieces to it and kind of lost interest. I need to tear it back down and rebuild it with two spacers and a locknut that fell off before I could torque it.

I remember following the gingery series, but never got into it because I couldn't see myself needing a lathe for anything, and still can't. I'm still hurting for a good hand cranked drill press, though.

>>125103
That sounds nice, but I was planning on just using an old electric oven once I get enough shop space for powder coating.

Where I live, its only $300 to get a car frame powder coated, so I'm not in too much of a hurry.

>>125091
Its all the better that you don't use the stove. Just want to get the radient heat from the oven working on drying it out. Might help to put it on a ceramic plate to even out the temperature and cool things down a bit if your stovetop gets hot enough to cause skin burns when the oven is heated.

Depends on the helicopter. The more expensive ones typically have better stability control.

>>125082
What sort of pressure are you running your feed line at? At about 8psi I can melt aluminum and still get 8-12 burn time out of a 20gal can if I turn it down to idle (2psi or so) between drossing and charging.

You might want to play with jet sizes a bit. I think I'm using either a T22 or T24 tweeco MiG tip.

>>125073
Its nice to see someone else on the internet that keeps their home cool in the winter.

I'd throw it in at 170F for an hour, and then leave it on top of the oven whenever you're using it for something else. Atop the stove offsets would be ideal, assuming you have a stovetop gas range.

Just make sure to rotate it often. It'll retain moisture on the side that contacts the surface its resting on.

Nice cupola design.

I've had a lot of luck with ceramic fiber kiln insulation, with or without ITC coating, it'll hold up so long as you lay fire brick in high friction areas.

Haven't had problems with my propane knife forge getting metals to casting temperatures all the way up to brass and bronze. Its volume is a little limited since its a horizontal design. Pic related. Its not my forge, but it has the same basic design.

I've been hoping to build a side draft waste oil cupola furnace once I've got the time for metal casting again. I've got the hot water heater waiting at home for me, too.
