Perhaps less about machining pewter buttons and more about holding them so we could. The pewter buttons have been cast in an open one-sided sand mold. The stars on the front face are the important face to keep. The open casting means the thicknesses are variable. The big issue was there was no easy way to hold them as pewter is quite soft.
- a tapered recess in the steel mandrel
- brass bobbin to stop the centre from digging in
- small amount of holding wax on the live centre to hold the brass bobbin roughly in place
