RE: cast gold
I haven't tried a lot to tweak the technique to get it to work, as I am getting nice fits with the Fastfire. I have only tried Beauty Cast and Nova Cast in the fine grain investments so, I don't know if another might work. Before I got the Cascom, I had what Microstar now sells as the Easy Cast. This was a vacuum (pull) machine which was ringless only, and gave me the same results. The Cascom is a push pull casting machine, so maybe if the air pressure is bumped up, it will push the gold, instead of trying to pull it through the fine grain investment. I guess I haven't thought of that before because I was using there suggested air pressure. I will give it a try (when I get caught up).
