newb question; oil temp

bladsmth said:
To heat up your quench tank,just stick the end of a 3 foot long piece of 3/4-1" round mild steel in the forge.When it gets red stick it in the quench and stir around for 10-15 seconds.Do this a number of times and the oil will heat up nicely.I realize that this won't work with a one brick forge or those using a torch to HT.
This weekend I will try to make a tutorial on building a 2 gallon,temperature controlled,recirculating quench tank.

i could use info like that cant wait to see how you go about setting it up
 
i have a question too about this. say if i get a peice of metal and bolt it to the knife say like a peice of like 4 foot flat bar and then heat the blade up can i put the blade into the oil like that? i was gonna use transmission fluid. and just heat it till a magnet dont stick then put the blade in as straight as possible. will oil fly all over the place and catch on fire?
 
As long as you fully submerge the heated knife, you will keep flair-ups to a minimum. Edge quenching results in a greated chance of setting the surface of the oil on fire. Once it's in the oil, there's no oxygen for flame to continue, so at the most you'll have a brief surface flair with a full quench.

I'm not sure why you would need the bar attached. I've heated early knives using a forge and a pair of vice grips while wearing gloves.

Thats an interesting question Kenny.Not because I didn't know the answer,(after hanging around here for a while you just know[if you don't,you should:) ])but because the quenchant I use(Brownells Touqh Quench) specifically says on the label - " IMPORTANT : USE AT ROOM TEMPERATURE - DO NOT HEAT ! " I'm not yelling at you guys :) That is just how it's written on the label ( capitals & ! included ) Since this is an "engineered" quenchant does any one else who uses "Tough Quench" follow the directions ?? I have always been curoius about this,I have tried it both ways & now just warm it to 90*-110*.Middle of the road,can't go wrong with that now can you :D BTW - I have always had good results with this quenchant but until I purchased a "Hardness Tester" could not accurately check the results and since the purchase have not experimented with the 140* or (what is room temp,about 68*?) I am anxious for feedback on this thread that Kenny started.

David,

Brownell's 'Tough Quench' is rebranded Houghton International's Houghto-quench "G". When I got my HQ "G" from Houghton, I was told the optimal heating range for what I was quenching is 120-125F.

Not to be a thread stealer - but - I'm working on a small skinning knife (maybe 6") and will be trying to heat in my kitchen oven. How small of a container of oil can I used to quench the blade? I just can't see getting several gallons of oil to do 1 knife. Of course I may do this again, but it's not going to be an everyday thing. Would one gallon be plenty? I'm about to change the oil in my truck so I'll have at least 5 quarts on hand. ;)
 
Well, since this seems to be a brought-back-from-the-dead thread.....

Clyde, you can't bring a knife blade up to 1500F in a kitchen stove.
Please read up on HT and you will understand more about the process. The type of steel will determine the procedures you will have to follow.
