Thread: lapping new natural oil stones?

Hi,
Is it a good idea to lap new natural oil stones? If so what should I use for lapping(sand paper, slurry stone, synthetic stone or something different?)
Thanks.

You should lap any new stone IMO. If you have a diamond plate (325) that is ideal. Alternatively wet & dry sandpaper on a flat surface will do. See hone lapping 101 in the SPR Wiki here.

Just start with a grid first to see the condition of your stone.

I don't have synthetic stones to compare to the stone. The oil stone is smooother than 1k sand paper though. Should I use 320 grit sand paper only? Do I need to make a progression (like 320,600,1000,2000)?

Some guys do a progression and you certainly can. I never have unless it was 120 to 325. I don't go above 325. Early on I lapped some with a 1200 plate but found out using the 1200 to lap waterstones would ruin the plate.

Will there be any difference between water and oil stones in terms of lapping?

You may add a drop or two of dish soap to the water when you are lapping, but there isn't much difference from what I have experienced. JimmyHAD has a bit more experience than most of us here...listen to him.
