foundry: wax

Chuck did some wax demos as well. He did several on surface techniques as well as fabrication using sheet wax. He uses a soldering iron as a "welder"...smart! He also demonstrated making a secure sprue and cup. Seems simple, but I know I've had some come off in the slurry just because I didn't take the time to do it the way he showed.

I'm going to have to make some custom small tips for my soldering iron now.
