Here are the CAD drawings for the new molds. I have included little tangs and stands to hold everything up and together. If it works I will end up TIG welding the little feet to one of the blanks plates so the mold part can slide out of one side. It will still need a clamp but at least it will stand on it's own while I pour. The plates are 3/16" thick which still might be too thick. We shall see.
I also tested the casting machine and so far so good. It seems to be in good working order. Working on a Zbrush model to print in wax.
