1- I have a lot of old coil and leaf springs. I want to use them to forge decent working knives. Supposedly that sort of thing is usually 5160 but what else could they be made of and what sort of HT temperatures should be used? Or just go to non-magnetic?
2 - I have an idea for a heat treating oven I can afford. I can control the heat in my propane forge from 1000-2100f by varying the inlet pressure of the propane. Using the dutch oven principal of baking I'm thinking of putting a 4" round section of Sch. 40 pipe, welded shut at one end with a hole for a thermocouple, inside the forge. I'll play with the propane pressure till I can get a fairly stable heat. Anyone think this might have a chance of working?
Thanks, this is a great forum.
