 hardening bearings
I'm using some bearings (a ball and a pin) to make some power hammer dies. I annealed successfully with vermiculite cooling, looking for suggestions for reharding-- air quench, water, oil, brine?

bearings as in 52100 stuff? Oil, for sure I would say.

Depends on if you want the wife to hang around the shop. If not, use fish oil or that from a fried fish joint, or motor oil from a '58 Buick that died awhile ago. Almost any oil will do.

Having used some really nasty stuff for quench oil, including PCB laden transformer oil ( worked real well!) and lots of drain oil...i'd say, go for deep-fry oil. When it starts to go rancid, either trade it in or cover it up and wait a few months. However, rancid quench oil and a big glowing bar of steel will rid your shop of gawkers, wives and tourists pronto. |
