Welcome - Laura Westenhiser

I am teaching myself to manufacture jewelry and could use some
help in techniques.

rt blanking, Jeff de Boer in Calgary Alberta, uses this
extensively. Bonny doone engineering, (on the net!) has alot of
info about this and other things. I once did a limited edition of
25 pins using hydraulic press stuff in 8 hours flat. Look at stuff
that is mass produced and learn stuff from it. I remember a friend
of mine who was casting flat back stuff but it had shrinkage
problems in the back, he found his solution in the chocolate making
industry where they cast open flat backed molds every day! Robb
