just got my parks 50 , and never used it before and was wanting to know when you quench in it how long do you hold the blade submerged in this thin oil.
i'm using 1095 and 1084 at this time
thanks vern
 
As with all quenchants, the blade should stay in the medium until it is cooled to well below Ms. Most folks pull it out once it is cool enough to handle with bare hands. I usually pull it out after about five seconds, quickly check for warps, and put it back in for a couple of minutes, until cooled.

Fresh from the can it should be around a 6 or 7 second count, with moderate agitation (moving the knife from tip to tang repeatedly through the oil), to reach 375F-400F. At this point you are safely out of the danger zone and can do as you please as far as allowing it to cool to room temp in the oil or in the air.

It is good to hear you say "submerged", as edge quenching will destroy this oil when the exposed hot portion of the blade bruns it up. With the blade entirely under the surface I have never flashed this oil, despite the fact that it has a very low flash point. Careful engineering has reduced the vapor jacketing below the surface to a point that you don't need to worry if you keep the hot stuff submerged.

Congratulations on scoring some of this oil that the manufacturer wishes to no longer share with the public. For the rest of us there is always Houghto-Quench 3440:).
 
I prefer to hold my blade in the oil solution til the red is completely disappear from the knife. Then I am comparable to let set on the wire basket in my quenching tank. This is one reason why I prefer the hard edge and soft back. :)

Then I place a top on it to hold the heat in til I can bring down the temperature in my oven. At that time its time to begin the second stage. The temping of the blade. Hope this was helpful in answering your question. At least from my point of view. Have good day and a blessed one. ---:thumbup:
