Ok, this is not a gun question, but I am making flat springs from 1095 stock and COULD be a gun question. I bought annealed 1095 flat stock, .025 thick for a project. No problem machining, hardening, and tempering the springs. But too strong. Need a thinner spring. Problem is, I can't buy anything thinner than .025" unless it is blue tempered. I can't drill it or bend it. A HSS drill won't penetrate. It breaks the cutting lips of a carbide drill. And even gentle bends crack the material.
I don't have a heat treating oven. All I have is a propane torch. I can heat the stuff up cherry red, and quickly plunge it into sand, but after it cools off, a file just glides off the stuff.
Am I not heating the stuff long enough? Or is it cooling to fast in the sand? Ideas?
