Going back to oilstones. Dry or fluids?

DMT has an excellent warranty / return policy... I suspect that if the stones failed as often as some claim, they would no longer be in business.

On a side note, DM, what's the difference in finish between the fine Sic and fine india? I was thinking of getting the large Sic C/F and a fine india, would it be the same or would it further refine the edge?

They are so close; the SiC c/f Norton's JUM-3 is 100/280 and the India c/f is 150/320 . I don't think you'd gain much getting the India just the c/f SiC is close plus it cuts better . Your mileage may vary . If you could find a decent older India the fine back in the late 80's was 600 grit . Sticks and Stones in Arlington, TX may carry some of those finer India stones . Try stickesandstonesunl.com . Hope this helps . DM

David, the real answer lies with the individual user. If the user bears down on a diamond stone, he'll tear the diamonds out of the matrix and the stone will wear out quickly. If the user works with light pressure as is instructed by most of the manufacturers, the diamond stones will last a life time. I have some that are 30 years old and still going strong.

I'm hoping this is getting more at the truth as I'd like for mine to last that long . DM
 
Not sure when I heard this ( brain's kinda old) , but if you have a brand new oilstone and you start using it with water or oil ,you should continue to use it with the one you start with. Not sure about this. I have an old Norton combo that was originally soaked in an oil bath for 3 days, and always was used with oil. I tried using water on it ,and of course being saturated with oil all those years, the water just beaded off ,so I suspect some truth to this. With my new one , I may just try doing things the other way around. I know they are somewhat pre-oiled, but it doesn't really seem to be too much. I suppose if I eventually don't like the water and go to oil, the oil will displace the water instead of the other way around. Maybe it all doesn't matter much. I dunno.:o
 
Wrap your oil stone in cheesecloth or an old Tee-Shirt and let it sit for a 3 to 5 days. Thay'll draw out most of the oil if not all of the oil on a new stone.
 
Modoc, It helps if its a nice hot day for that to work . I layed them on top of a wood burning stove wrapped like that when it just has simmering coals and it works . You can also boil it in a large pan of H2O, remove it, dry it and let it sit on the tee shirt until cool and this gets it out pretty good . Your call . DM
 
I remember seeing some old New England farmers/hunters throwing their gunked up stones (I'm guessing they were silicon carbide stones) right into the fire at deer camp and letting them bake on the coals for the evening to clean them up. In the morning they fished them out of the cold fireplace, and just brushed them off.
