I got a box of A2 at an auction. It included a 3/4X1 1/4 inch flat bar. I used it to make a tang filing jig I have seen on the net.
I used 3/8 inch W1 drill rod for the pins. Now I need to heat treat the blocks.
I found a recipe that called for stress relieving, preheat, and hardening.
Do you keep the part in the same foil for each cycle?
After hardening do you take it out of the foil to cool in "still air"?
Should I set it on a brick or metal to cool?
They describe putting wood in the foil. Would wrapping the part in paper do the same thing?
Is there a need to heat treat the pins?
Is there something I am overlooking?
Thanks!
