Where is a good source to buy sharpening stone cutting oil. I have a 3 stone industrial sharpener. The tray holds the oil, so the bottom stone always sits in oil. Can't find any large size cans in hardware stores around here, just small little squirt cans. I'd have to buy about 20cns just to fill my tray reservoir.

Home Depot sells WD40 by the gallon can. Not the best in the world, but it works.

Quart bottle of mineral oil, from the drug store, oughta work, too.

Ideally, you would want a 10 WT oil for that, plain mineral oil with as little additives as possible.

just a thought but if you have a Sams, Cosco, or Tractor Supply Store, they sell hyraulic fluid by the 5 gallon pails. If you can find a ISO 32, either R&O or AW, that would be a 15 and if you needed you could cut it with mineral spirits.
5 Gallons would be alot, but it should only cost around $30 and you would have some to spare

Thanks for the suggestions, what i was using, but I just ran out was, Norton white mineral oil. I had a qt can. I had tried tractor supply but I was looking for mineral oil for sharpening stones and they had nothing like that. I didn't think to look for drill bit cutting oil. They should have that. I sharpen all my knives (hunting, and kitchen) so i'm concerned about oil residue left on the blades. Of course I clean them after I sharpen them, but just don't want to take a chance on contamination.

tractor supply sells gallon jugs of mineral oil in the horse / cow feed section.

you guessed it. BIG horse enemas! ( really! ) I have horses.. cows, chickens.. pigs, turkey.. etc.


Walmart / walgreens ALSO sell mineral oil.. some by the gallon.. some by the pint... but TSC will have it for sure.

Suggestion I read, years and years ago (back when coffee came in three-pound STEEL cans) was to store your stone in a coffee can full of kerosene.

I just noticed the other day that my local TSC store also carries non-detergent straight 10W oil in 5 gallon containers for $24. Straight 10W oil would be a good match for most edge honing applications. Also, after using the rather pricey (lightweight, purplish ATF appearing) Buck's honing oil satisfactorily for many years I tried a replacement mixture of dollar store lamp oil and generic dollar store ATF fluid. That worked quite nicely in a 50/50 light weight mixture. It held the metal slurry nicely in suspension which enabled a quite fine edge to be developed. As you go to more porous coarse stones increase the ATF percentage a bit.
