Who sells the best , or best value oil for deferential harding 52100 and 5160 ?

Been triple quenching hunter and small Bowie size blades in Mineral oil , it's time to advance to the real stuff.
Ed Fowler mentions Texaco Type 'A' , but I have not been able to find it on-line.

Thanks in advance!

If by differential heat treat you mean putting half of a hot blade in the oil while the other half of a hot blade remains outside the oil, go with used diesel or bacon fat. I say this because you will quickly degrade/ruin your good HT oil by setting it on fire every time you HT.

If you mean clay coating a blade and fully submerging it in oil, check with Darren or do a search, since this has been discussed many times.

Best,

That is a good point, as I have been half-heating (spine not to critical) and half dipping , I may need to perfect my approach. Experimenting, by using a soft torch, I have found that twilight hours, early mornings and evenings help, so I can see shades of red better, establishing what shade of red I want with a magnet, and bringing that shade along the cutting edge, leaving the spine a duller red and still magnetic.

I have dipped the whole blades and can still scrach the spine with a file,,,,but can't touch the part that was critical. Thanks for the pointer, as it makes sense, and would be more consistent.

My take is that flames are burning off some of the ingredients in the quench?

Thanks for the link,,,,,, Darren Ellis 'Is the man' ! as he also has what I need for my day-job forge traveling with a forge is hard on them to say the least, I will be giving him a call today.
 
Belive it or not, I would agree with the 10w30, diesel or bacon fat, or the cheapest commercial quenchant you can find. Repeatedly flashing will quickly reduce any quality quenching oil to the equivalent of the aforementioned anyhow.
