Hi guys.
I recently found a company selling Aluminum Oxide ("India" style) oil stones in the weird dimensions that I like to keep in my portable tool-sets (1.5" x 4-5"). So, I picked one up.
But, it has one major "flaw": it wasn't prefilled, and oil just soaks through.
So, I gave it an oil bath over night and it soaked up all the oil it can hold, but it's still terribly porous and oil mostly just soaks through to the bottom, making a mess and not lubricating the stone.
I have had similar experiences in the past trying to fill carbon stones, without any luck.
I'm using a mineral oil / all purpose "3-in-1" style oil. I've tried both lighter and heavier oils of this type with the same messy results.
Perhaps I simply need oil that will dry into a wax? Norton's India stones come prefilled and don't exhibit this behavior; what do they use?
Maybe I should just order some along with a few Ark's from Dan's... Shipping to Japan is really expensive though
