CPM 3V heat treat

[BlueSun]

I'm working on a competition chopper using 1/4" CPM 3V. It's my first go at this particular steel and size knife and I'm wondering if my 6"x12"x1" AL plates are large enough to quench (with air) the blade properly. My other possibility per the spec is to interrupted oil (Parks 50) quench to about 1000F then cool using the plates to 125F. I'd rather not buy another larger set of plates ATM.
Thanks

should ask in the knifemaker forum.....

If somehow I have to normal ht quench a BladeSports specs 3V 1/4" thick chopper using 6x12x1" Aluminum plate, would quench as follow:

Cut 4 rectangular pieces of watermelon 4x5x1.1" thick.
Quench blade with 3-3.5" of tang protruding out at one end; use 2 pieces of watermelon to quench the protruding part for 20 seconds; then replace with 2 fresh melon pieces for another 40 seconds.
Remove foil, straighten if needed, still air cool to near/at room temp, cryo, ...
