Attempted casting of guitar knobs. lost foam with a 3/16" drill hole and machine screws going into the sides to hold it tight. The problem was the machine screws are either too loose or tight. casting the threading around the screw is not the way to go. updates to follow if I think of a new way to make this work. I think a tap and die set might be the way to go.
