Thread: Curve on a norton set of stones. Maybe.

So i just neet one DMT-325 for lapping all my hones? Is that something i would want to use to chamfer the edges too? Will I also be able to use it for corrections on my Swaty? Heaven forbid it gets a chip.

Can't lap the 220 with 325, you can lap the rest. But you can use the 325 for honing instead the 220. You can chamfer the edges with it,yes, again not on the 220. So you are replacing the 220 with 325 for honing and also it becomes your lapping surface.

Also, even if you get the 120 I would not suggest to use it on the 220. You can but not recommended. Your 220 basically becomes obsolete once you get the DMT, you can lap with sandpaper and use for knives.

Why wouldn't you lap the 220 with it? is the grit difference too close?

You can of course lap the 220 with the DMT 325. Nortons comes with a quite rough outer surface that needs removing before they can be used.
A DMT 325 sure is a must have.

Lapping a coarser grit with a finer grit can cause damage to the finer grit stone.

I can't imagine a soft Norton 220 doing any damage to a DMT.

You might be right... TBH - I have never tried it.

Have you done this?The reason why I am asking is because I have the same set up as OP and I purchased DMT 325 as well. I understand there is difference in grits between brands and that the DMT is much harder than the Nortons but I do not want to run the risk of wearing the DMT much faster than what it is supposed to for a hone that is pretty much no longer needed after I purchased the DMT. Thanks.

What about a 4 stone set of 8" Dia Sharps? would that be a good set to have? Had i not already invested in the norton stones.
