Rubber feet for the Challenge Proof Press
Proof presses are subjected to a lot of sideways forces when used, caused by the carriage hitting its stops at either end of its stroke. These can be reduced by slowing down near the end of the stroke, but there…

Last Saturday I tried again to do a run of composition casting. At some point, the galley mechanism stopped working, and a very long line developed in the galley. I stopped casting and looked for the cause of the problem.…
