OK! Somebody tell me if it's to dangerous or is it's safe to do. My Marlin model 93 has a worn out lock block. Can't find a replacement anywhere. I want to build it up by torch. I can't electric weld but I can torch weld and braze. I guess the lock block is hard steel and as far as I know only mild steel can be tempered. But if tempering needs to be done then I have what everybody else has accesses to, being water of all temperatures, fresh and salt water, used engine oil. OR, is this something only a gun smith can do? All comments are welcome.
