I've been a jeweler for 40 years now. I've only had an investment blowout one time, and that was due to my not weighing and measuring the powder/water ratio correctly. What investment are you using? I'm a tool junkie as well. I see you have a couple of steamaster steam cleaners on the floor. Those things are built like tanks!
Haha yeah I inherited them. Both are broken so eventually I want to fix one. I haven't done any casting for a little bit. I've been too busy with work to even make a video lately. I don't remember the brand but but it ended up being due to not filling the flask all the way. Rookie mistake haha
