Thank's Joel. Your comment about repairing dents or divots in the press die reminds me of some sheet steel we bought one time that was made entirely from recycled automobiles the problem was when this is done some of the metals are quite hard like bearings for instance once the cars are run through a shredder there is hardly anyway to insure no bearings are in the mix. Forming shearing machining or even just drilling these sheets were a challenge. I can see these as causing problems in press dies
Do you have a way to re harden the surface area of the repairs? perhaps localized induction heating cooled with a spray of liquid nitrogen could do the trick
