Hi This is my 2nd request for info.on soldering pot metal. Pot
metal or zinc die cast metal is in question.
I have a book PRINCIPLES OF CENTRIFUGAL RUBBER MOLD CASTING by Jerome
A. Gonicberg and Marshall L. Ritch published by The A. J. Oster
Company, a casting company. The book covers moldmaking and casting of
pot metals. They have a listing for consulting/troubleshooting. You
might write to them and see if they can help you or direct you to
someone who can.
