Topic tags/keywords: flatten oil stones

My bench is set up this week for sharpening and I’m going through all my planes and chisels.

This is the first time I’ve used sand paper on a granite plate and I’m pretty impressed with the results. I set up with the following grits of emery paper 220, 400, 600 and 1,000.

Does that sound about right? The 1,000 grit definately shines them up better than my Arkansas stone.

For my nicked chisels, I’m re-grinding the bevel on my India stone, then going to the Arkansas and then going to the plate for 600 grit and beyond.

When checking the stones against the plate, I can see that they are slightly cupped (~1/16” max. over an 8” stone)

Is there a way to flatten the stones? (I have access to a mill and surface grinder at work…. but don’t want to wreck my stones or the grinding wheel).

Thanks in advance for any tips.

80 grit ont he granite plate sounds like a good option….

Especially since I just recently boke the seam on a fairly new belt on my 4×24 belt sander.

I knew that would come in handy some day…. just didn’t know how :^)

you can also just rub two stones against each other
but in both cases be sure to check out for grits from the corse sandpaper or stone
hasn´t come on the finer stone ….. you deffently don´t want to have that experience in the mittle of a sharpening session

Yes! I’ve used a coarse DMT to flatten an oilstone before.
