Topic tags/keywords: question

I just inherited a Norton Multi-oil stone (w/JAS-3, JAS-6, and JAS-9 stones in it):

The oil in the pan is ancient and clearly needs to be replaced. Do I just dump it out (send it to hazardous waste), clean the stones with mineral spirits, and dump , baby oil in the thing (looks like Norton sells their own oil, too) or is there a better solution?

Thanks!

Wade – I also had one back in the ‘70s that I got from a Navy base galley
that had tossed it out. they used vegetable oil in the sump and it turned rancid
and gummy which caused them to toss it.
I tried every solvent I had access to to try to clean the stones.
gasoline, kerosene, various thinners and solvents, WD-40, carbon tetrachloride,
boiling the stones in a commercial degreaser, and others I can’t remember,
I never did get all the gummy oil out of the pores enough to make it a decent sharpening system.
I sold it on ebay around 1990 with a full disclosure that it needed a LOT of work.
hope you get some positive feedback on what will work for you.
if you don’t know the full history of it, there is no telling what oil has been used in it.

Wade – I forgot to mention that the stones I had were man-made.
probably aluminum oxide or something similar. so if you have natural stones
like the Arkansas, they may be easier to clean.
dispose of your old oil just as you would with cooking oil, lawn mower or motor oil at the auto store.
again, if you don’t know its full history, there is no telling what oil has been used in it.
it is pretty expensive on today’s market, hope you can get it functioning properly.
this is the 3 stone model I had.

Thanks, John.

I’ll give it a go. I also inherited a Work Sharp 3000 so it might not be a catastrophe if I can’t get the Multi-Oil in a working condition.

I use Arkansas oil stones. When they need cleaning I just soak them in kerosene for a day or so, scrub them with a stiff brush, wipe them off and put them back to work. I use mineral oil as my sharpening oil. I would like to add a Work Sharp to my sharpening station, it would be nice to have that option when needed.

Hope you get the multi stone in working order! There are soooo many sharpening tools & methods it can get mind numbing. I wish I had a flat granite surface plate and some super fine wet sandpaper for most sharpening. Stones are not bad but they do need occasional reflattening and cleaning. The lazy in me doesn’t like maintenance much :-D. But the worksharp should do great for most needs. I’ve pined after a tormek for years but haven’t made the financial jump since I’m not using my shop to make a living and haven’t used turning tools (yet). I did get a nice low speed grinder with Norton 3x wheels and the one-way balancing system just in case :)
Enough rambling. Best wishes to you and the woodshop!

Alex, a granite plate can easily (and inexpensively) be obtained from a granite countertop fabricator. I have a sink cutout that I use often, and it was FREE.
I’ll almost bet ya that there is one such fab company near you.
Most auto body suppliers sell a top grade of wet/dry paper.
Good luck on your search.
