Just got done making a new set of dies for my tire hammer out of 4140, old dies have gotten pretty sway backed and out of flat. The person I bought the hammer from 10 years or so ago had ground them to half flat/half drawing and I reground them flat so there isn't a lot of room to re flatten them.
Anyway, I went by the plans and got them welded up and ran a normalizing cycle on them.
Just need to quench and temper and lightly dress them.
My question is, do I use water or Parks 50 quench oil, and what temperature to temper them at. The dies are 1 1/2"x2"x3 1/2"
Thanks
