I find it somewhat odd that any good Gunsmith doesnt do minor heat treating on small parts. That is kind of a requirement seeing how most parts will be made using a soft steel and must be hardened, or tempered (screws, pins, springs, sears, etc). A small oven, lead melting pot, hardening powder and torch arent really that expensive or difficult to use.
Cole Haugh is probably the guy your friend used in Indiana. Hes really good...he had an excellent teacher.
Last number I had for him: 812 654- 3209
and this local "gunsmith" is mostly an excellent stock maker and repairer but can do small stuff.
thank you, I bet Mr. Haugh is the fellow my friend used...I will check !
