Thread: Lapping a surgical black Arkansas

I agree that arks will eat a DMT, I lost one to arks. Sand paper, Belt sander and old carborundum stones have worked for me. I just received a bunch of loose polishing grits from Got Grit, based on a thread here a month or two ago on lapping stones, with nice photos.

I bought a few Arks & Indian oil stones that need lapping. Harbor Freight sells a set of cheap Diamond stones they are a bit rough, but they are about 12 bucks for 3 and work great for hogging off material, then sand paper then carborundum to finish.

I will post the results of the grit lapping, when I get them out of the TSP. They keep releasing oil. The other thread makes it look promising. Got Grit is a telescope lens grinding site, so they are grinding glass.

Bottom line DMT and Arks… Arks win every time and can get expensive.
