March 29, 20215 yr Finally got around to chabging from used motor oil as my quench oil to canola oil. First time i used it today. I have to admit, it smells a whole lot better than used motor oil. And i didnt feel like i had smoked 3 dozen packs of smokes in one breath. Oh, and i made a hook today as well! Since people are gonna think this: no, i didnt quench the hook in the oil. Im making a chefs knife and quenched the blade in the oil.
March 29, 20215 yr so maybe this should be in heat treating and not general smithing convie? I will move the post. I also suggest you read this thread
March 30, 20215 yr Good to see you FINALLY made the switch! The smell of burning canola oil may be a general observation but it's directly related to heat treatment. Playing semantic games with admin or the mods won't do you any good at all. Worse than that, playing silly buggers just to show you can is going to lower your respect with the rest of us who aren't silly buggers. If you do a good wire brushing on the hook and heat it above smoking hot, dull red is too hot but not enough to do bad things. dip the heated hook in the canola oil and it will put a reasonably weather proof black finish on it. Anything around 400f and up will put a finish on steel of various darkness. Frosty The Lucky.
March 30, 20215 yr Author Im a semantics kind of guy. Especially if the reasoning for something isnt obvious to me or made clear. I ended up putting beeswax/linseed oil mix on the hook. I know the hook wont be outside, but i still wanted to coat it. Ill have to try the trick you mentioned. Never would have thought of it. Thanks!
March 30, 20215 yr Fellow Denizens, A good buddy of mine twigged me to a capital trick. He scavenged used oil from some of the fryers at the local Tim Horton and Duncan Donuts shops. There a lot of them in Canada, so he always had a ready supply. Quenching, always, gave off a pleasant aroma. ('odour' in Canada). SLAG.
March 30, 20215 yr I got a big blob of bacon grease in mine. As with all things bacon can only make it better.
March 30, 20215 yr As to using it as a finish---you are basically "seasoning" it like a good cast iron skillet.

I get my quench oil at the local Safeway deli section, they change fryer oil every couple days. I have a CLEAN 5gl plastic jug with my name and number written in permanent marker. I drop it off in the morning and it's usually ready for pick up in a day or so. I call ahead or stop by. Don't leave it there long. I was REALLY hoping for pastry oil but got: burritos, fish and French fry scented, shop incense. Frosty The Lucky.

March 31, 20215 yr Frosty, for a minute there, I thought you were going to suggest bear grease (Do much camping in bear country?) as a quenchant!
March 31, 20215 yr When buying new oil or scrounging from friends & neighbors who use turkey fryers, I like peanut oil. It smells better than canola and has a higher flash point.
