Two things prompted me to get a different quench tank. First, I discovered that it was better to heat the oil by heating the tank instead of dropping a piece of hot steal in it. The oil doesn’t break down as fast. To be honest, I didn’t even think about the oil breaking down.
I plan to add a block heater to the quench tank but for now I’m just sitting a torch beside it until it hits a little over 120 degrees.
And the second reason was I was starting to think about making longer knives.
It only takes a couple minutes with the torch to heat the
oil to approximately 130 degrees.
