just a few 1095 heat treat questions

[Brett Holmes]

i need to treat some 1095 in the next fewdays and i just need to clear a few things up before i do it, i dont want to short change anyone, when my kith blade gets sent out.

1. Everyone says 130deg F for the quench oil. how do i know how hot it is?? does everyone just guess?

2. I plan on using veggie oil. can i use the stuff i took out our deep fryer last week? its veggie, i cant see how its quenching powers could be used up.

evryone throw your favorite tempering times at me please, so i have a few theorys to choose from.

thanks Brett

I had mixed results using veggie oil with 1095... never seemed to get the blade consistently hard, until I switched to Brownell's Tough Quench. SO far, it has worked every time, with no heating required.
When I used veggie oil, I stole my wife's candy thermometer (although a meat thermometer will work, too). Also, veggie oil will work up until you can't stand looking at it anymore... so you should be fine. Are you planning on an edge quench?

Good luck!

Temper immediately after quenching and for at least 1 hour. Depending on the steel usually 1-2 hours and that might be repeated .

Mornin Ya'll,
Of the 26, 1095 blades I am endeavoring to heat treat,
{for the first time.}
I was stopped at '7', by the magnet sl##ing off the metal rod I had it bailing wired to.
I heated and bent the rod tip, to better hold the magnet,
and after lunch, today, was going out to harden some more.
I have, 19 {unhardened} blades on the stump by the forge,
and, 7 { hardened???} oily blades which are hardened to the best of my ability,
albeit, not tested or tempered, on the ground under my 'Tisch' forge.
I had no ##ea how much time hardening 26 blades would take.
And had planned on hardening them all before removing the oil and tempering.
But just noticed old 'Mete' say that the blades should be tempered immediately after hardening. {Opps}

Should I re-harden them before tempering?

And since I have Ya'll here,
how would I get the dern oil off the blades before putting them in my oven !!!
The car wash ???


Monday mornings... Hmmm...

Don't reharden ,if any damage has been done it's too late anyway. Oil comes off with detergent, boiling makes it faster, or solvents .If you're tempering in the kitchen stove removing oil will please the wife !!
