DiY Foundry Update
« on: February 23, 2016, 07:35:30 PM »
Soooo I know It's been a while, but here's my updated gear I put together. I made a gas extractor for degassing investment plaster. I used a plastic bowl, a neoprene rubber gasket, a 1/8" thick galvanized steel plate, an old bathroom cabinet for a base, a vacuum pump, and regular brass fittings for the pump to connect to.

I also made a vulcanizer using hardwood, red silicone as an insulator, steel plates, light dimmers as dials and stove top heating elements as the heating coils. I put springs in between the bolts and the plates holding the elements to account for thermal expansion of the metals.

Also, I made a wax injector out of an old aluminum container, a self-heating cooker, a steel plate, some threaded rods, and NPT brass fittings. I custom made the nozzle out of a 1/4" NPT brass coupler that connects to the ball valve on one end and is soldered to a plasma cutting tip on the other side, that is drilled to the standard hole size of a sprew former.

I'm rebuilding a kiln right now and finishing up welding together my vacuum caster. I'll post updates soon. Feel free to ask me any questions. Everything works and is totally cost effective. Don't spend thousands on gear, when you can make it yourself.

Oh yeah, that's a veneer screw I used on the vulcanizer. It's just bolted down on another plate centered on the top plate. I used 12ga wire and grounded the dials to the box. Be sure to be safe when building anything like this. There are potential electrical, fire and pressure explosion hazards involved in making these things. Always wear safety goggles when drilling into metal.

Oh and don't use a glass bowl. You need something with the consistency of plexiglass.

DIY rules and it looks like you are one of the rulers. It would be great if you would move next door so we could cobblerate/collaborate.

Thanks for taking the time to show your work.

do you have a pressure regulator on your wax injector?  What pressure are you planning to use to inject the wax?
