How not to store quenching oil.
Just a quick reminder of forgetting the (duh!) simple stuff can cause unexpected results.
As mentioned in another thread, oil-quenching O-1 stock was done on a couple punches. A plastic film canister (remember those?) was used as a reusable container for the ATF. Seemed like such a great idea; an easily stored, no spill container for quenching small parts…NOT!
It worked perfectly on the 1st punch made from ¼” stock. 3/8”? Not so much….
