Thanks, I think I got it, put the clay on before you heat it up, correct, I have just been getting them non magnetic and the quench in oil, it's pretty hard so then in the oven at 450 for a few hours and let cool, seems to do a pretty good job but I am sure not very precise.
Thanks for your help, I am just starting and have a lot to learn, Right now just doing it in the fire with a blower I have set up. Need a forge and plan on that soon.
