i just changed my oil and was wondering if mixing used 5w30 synthetic blend with veggie oil work for a fast quenchant? as some of yall know im using 1080. still waiting on my tax return so i can order some fast quenchant from darren. either i get paid by my job or by the gov but once i do ill be ordering quenchant. but for now i was wondering if what i have would work.
 
I've been using just straight canola oil for a good while..... warm it up and it works fast... way less smoke then motor oil... and you can get it cheep if you shop around..

ive been using veggie oil i got from the dollar store as well as some expired sunflower oil mom gave me. its about a 50-50 mix. ive been warming it up to about 120-140.
 
The formula for fast quenchant is :
5 gallons warm water
5 pounds rock salt

Don't try to mix up your own fast quench in oils. Just use a good oil as it is. Fast quenchants are special oil types, but canola and peanut oil seem to work, OK.

Go to bed.

so its basically one pound of rock salt per one pound of warm water. Stacy, so i should just use the veggie oil i have as is and not add the 5w30.
 
One pound per GALLON. A gallon of water weighs about 7 pounds.
A brine quench is the fastest quench,but is quite severe. It is mostly used for creating vivid hamon on shallow hardening steels.1095, 1080, W-steels, and a few others will take it, but there is always the chance of PING!!!

Yes, stay with the veggie oil.

Well,,,,it will work ,,,sorta...

The truth is that most everything you could name will work as a quench fluid....even goat pee...LOL

But what is important is that you dont end up spinning your wheels with an attempt that cant be learned from.
You could invent your own mix of a little of this, and little of that, but if the blade cracks during the quench we have to have some idea what we can change next time.
An invented quench oil has so many unknowns that it would take you years to find out what is the correct mix of this-oil to that-oil.

So,,,,My advice to a new guy who wants to make a blade: is to use a real quench oil.

HOWEVER, as we all know full well that many quench oils are a ton of money, then my 2nd advice is to use a simple quench oil like mineral oil, etc, and then save your money for the good stuff to get as soon as you can.

Once you get a real quench oil thats a good match to whatever type of steel you use, then you are in a position to really start to learn how to work with your steels...

But it's imporant to keep busy, keep your forge going, keep learning how to bang the hot steel into shape, so I understand the need to "make-do" with whatever you got handy right now. Lets face it, there is no point in building your forge if you just are going to stand next to it as you waite for a stupid can of oil. But it is also important to remember that a good quench oil will be a big help in the long run.

remember, even if a good quench oil takes a bunch of money, you dont have to get that much of it,,,and it lasts a long, long, long, long, long long....Long time...
I got 2 gal of texaco type "A" a few years ago, and at under 20 knives a year I can use that same oil for the rest of my life, and if after Im dead someone else wants it?..they can use it for the rest of their lives too...it lasts a long-long time.
 
I have a booth at the local street fair and yesterday some Army Ranger comes along complete with fatigues and the who nine yards and he spots my K bar and wants to know if I will make him one. I said no problem. Then he wants to know if I could quench it in pigs blood??? I thought a lot of things for a bit then knowing salt water and I have heard of this in history, I said well maybe. I figure I could get all I want at the slaughter house. Any comments in case this government issue oddball wants to pony up the money. I could actually care less about the religous ethics if used on someone fighting one of ours. The K bar I have on display is going to my niece soon as she is making the big trip for the USMC and I used a bit of pig fat in the quench myself. Semper Fi
 
Olive oil works nicely, and smells like cooking good food. The resulting scale cleans up well,and I have been using the same oil for years.

I think I know what he's getting at. You might point out to him that according to the Koran, accidental contact with pig or other unclean stuff, isn't going to doom a muslim. If it's all they can get, they can be forgiven for eating it.
I'm no expert, I just looked it up somewhere, and of course interpretations may vary. *shrug*

I bet quenching in blood would stink anyway...blech.
 
you'd have to get it fresh and whisk it hard to stop it clotting. once clotted you might as well quench in a black pudding.
 
I know war is a horrible thing already but it makes me sad to think a person would wish someone to hell and actually try to help him along. I think that would qualify as a sin no matter what God you pray to. If that is the thought behind the pig blood quench that is truly one of the saddest things I have heard in a long time. I know hating the enemy is part of any war but I would hope in death we can at last put aside our differences. That just screams "sadistic twisted mind" to me, I would not make a weapon that was part of sacreligous killing. Im shure when a angel smited his foe he did not feel the need to desecrate the body.

Dont forget the people he is supposed to be helping and freeing are also muslim. I dont think spitting on there beliefs will help us be seen as liberators or even good people.
 
the sort of guy who wanders around a street fair in the "hole nine yards" screams "WANNABE" to me. none of the top soldiers i knew ever wore DPMs off base unless on duty, and few wore their ribbons unless compulsory.

Pretty much the picture as I saw it too. Plus the blood quench was way over the top. I could care less and if he wanted to pay me to quench it a bucket of toads eyes hes on if he wants to pony up enough cash. I would be tempted to call up his base and ask them if they were aware he was a section 8 canidate

I personally have no problem with most Muslims. I do have a problem with fanatics be they Christian, Muslim, Jewish ,Druid or what ever. Anytime someone starts thinking everyone who doesn't believe as they do should die they can take a long walk on a short board as far as I am concerned. If someone is trying to kill me or mine for what ever reason I will do what ever I can (even phycologically) to sent them on their way and I don't care where they land when they get to what ever eternal gates they have to pass thru.
 
While agree there is litlle room for compasion towards alqueda and other terrorists of any denomination I dont see how knowing there is pig blood on your blade will give you any tacitical advatage? I seriously doubt the person being stabbed or sliced would bother to ask and equally doubt he posseses the vocabulary in there language to tell them. Hence it is only for his own personal gratification metaly or his pleasure thinking he is sending people straight to hell. Again, sick demented mind or whatever, not someone I would do work for for at any price. What if he is a section 8 but the mentality he has leads him to use the knife on someone closer to home? I avoid dangerous people and certainly wont proveide them with sharp objects. Just my 2 cents. I would of course make a knife for a GI going to the sandbox but most military I know are real people who dont want to kill anyone, let alone revel in it.
