The fact that industry is making non petroleum based quenching fluids for improved worker safety makes me think that oil based quenching fluids can effect you in a bad way. One msds I checked states " may cause respiratory or other pulmonary effects following repeated inhalation". Now that being said I work in a refinery and huff a lot of oil fumes and mist on a daily basis. I don't like adding to it at home. But judging from some of the responses I sound like a know nothing crackpot.

Thanks stormcrow I do like the canola oil for the lack of hydrocarbons

Thanks
that seems to be 22 cenastokes @40 deg. C. I will see if I can covert to kinamatic for reference
And sorry I put it in the sword section because that is what I am working on. Figured go to the source for info.
Centistokes and kinamatic is basically same.

Hello
i am upgrading my 25" quench tank to a much bigger 50" tank. I have been using veggie oil with some atf to try to keep the flames down. I have had good results with this combo. I have broken a few blades and found a nice small crystalline structure. But going to the new tank I was thinking about upgrading to a actual proper quench oil. But before I buy 15 gallons of the stuff (not cheep). I was wondering what most folks are using here. I have looked at the stickies under sword, knife and heat treatment they usually just say oil. Now being I work in a refinery I have a little knowledge about oil (very little). The research I have done so far shows a wide spread in viscosity for quenchent oil. I will list below. All will be normalized at 40 deg c /104 deg f. And shown in kinamatic viscosity for reference
10% brine - .85
isodur 160 - 10
isomax 166 - 12.5
chevron 70 - 16.5
isodur 220 - 19
isorapid 227 - 24
hydrolic oil - 30
vegetable oil- 34
trans (atf) - 35.5
isorapid 459 - 49
sae 30 - 88
so I found a great spread on quench fluid viscosity and added some of the other things people seem to quench with. I know quench oil is made from a base oil with a anti- oxidation addictive. I am tempted to stay with the veggie oil as I know it well. The real question is how many folks around here are using quenching oil verses something else. Hopefully I have done enough research on my own so I don't get yelled at for asking questions
Regards

Wow, That's an amazing looking blade. What is the finish on the blade?
-
Looks like that beast would cut through just about anything. Nice work

Hewing spear/glaive? Pretty cool! Think I'd put a cordwrap on it for comfort.
I was thinking the same thing. I may change it to a solid color.

No I don't. Let me tell you swinging a 10 pound hammer and holding the stock kicked my butt

I was thinking light cutlass or wakizashi type blades. Not sure how the hilt would evolve single handed I would think.
-
I like the what if part of this. I would think that if swords stayed in fashion a short slashing blade would evolve. Easy to carry in cars and around busy towns.

That's a good looking chopper
-
That looks great. I have been thinking of building something that size. How does it work on 1/4" stock? I mostly do knives and small stuff and have been looking at hydrolic presses but think the speed of a power hammer would be better.

Yeah after I finished it I thought it would have been handy on my last boar hunt.
-
Haha. I suppose so.

Looks good. I got some scout 2 springs that need to become something

Very nice blade

The horseradish patina is easy. I do it on some of the knifes I make. You polish the steel up a bit then you dab the horseradish on the bare steel. Leave it on for 10 minutes wash it off with water. Do this a few times. I usually do it 4 to 5 times for a knife. It will give a dark patina like an old carbon steel kitchen knife. I read about it in the 50$ knife shop book. He also said he uses mustard. I have not tried the mustard myself though.

I like to use horseradish to patina blade. Seems to not rust so far.

That is very cool love the bolster.
-
Very cool. I like the skate wheels. I am almost ready to build one myself. Soon hopefully
-
That's very nice. I heard they could break an anvil in a sandbox. We got millwrights that can do the same
-
I just saw the movie this weekend. Nice likeness looks good.

Thanks for the kind words. At hay river, it is a left hand holster when I drew the pattern on the leather I put it on the wrong side. Was trying for a a right hand holster. Luckily I have a second peacemaker that still needs a holster

Yes I misspoke I meant petroleum based hydrocarbons
