We finally have an oven on its way, it is an Evenheat KF 18 w/Rampmaster controls. Needless to say, we're pretty stoked about it! Currently, we are working with O1 and CPM 154. I've done quite a bit of searching/reading through posts on here, but still have a few questions:

1.) With regards to the quench tank for O1, is there a minimum (in gallons) size we should shoot for? Also, can someone explain the difference or benefits of vertical vs. horizontal quenching?

2.) I'm sure there are a number of factors involved, but typically how many blades do most heat treat at a time? I imagine it is hard to control the temperature of the oven if you are constantly opening and closing the door to remove blades?

3.) I assume Parks 50 is the preferred oil for quenching, is Maxim the best place to get it from?

4.) For the CPM 154, we are considering 1" aluminum plates that are 6"x12". Most of the blades are 1/8" thick and 8" or less in length, will the plates be okay? Also, is there a benefit to quenching the steel while still wrapped in foil?

Thanks ahead of time for the help.

Click to expand...

You have to match the speed of the steel to the speed of the quench using a TTT graph.

Parks 50 gets lots of press, but it's a fast oil suited for 1095, W1, W2 (and a Hamon)

You need a slower oil like Parks AAA or some other similar oil like a Houghtons type G
 
Maxim has Parks AAA in five gallon buckets. McMaster Carr 11 second quench oil will also work for 01.
