Jogrand,
I've flattened severely pitted oilstones by lapping the face on PSA-backed 220 grit silicon carbide sandpaper mounted to a piece of MDF. The MDF is flat enough to yield a fairly flat face on the stone and the sandpaper coarse enough to remove material. The paper will load quickly at first so you'll have to change it frequently. Once the face is flat, finish it off with 320 grit paper or a diamond stone.

If this discussion was useful, there are twenty years of them here. Join SAPFM to take part — the forum, the journal, the magazine and the members’ gallery come with membership.
