Great video!! I've been casting bronze mounts for miniature furniture for years but have never had a debubbling machine. I usually put my investment flasks on my fretsaw which vibrates and tap out the bubbles with a stick. I can be hit and miss depending on the thickness of my investment (I don't measure it, I do it by eye). After watching you vodeo I just bought your debubbling machine, can't wait for it to arrive. I'm going to use my compressor in reverse with the machine but am concerned how much pressure I should look to get when I run my compressor. When I use my wax injector I have a precise setting I use and wondered if degassing will be similar...

Watch the investment mixing video by Jason Chandler on Instagram. Look up Portland Jewelry Academy and then scroll down a bit to find the video. We are now mixing based on this video and our casting quality has improved significantly.

For the handle, you could thread tap a hole to screw in a removable handle. If the hole compromises the vaccum chamber add an o ring or gasket.

I have a 3 CFM 2 stage but it may work with less although I haven't tried it.
