Thanks. I was pretty pleased with how the stone wore evenly, but still, shouldn't have let it go that far.Checking is good - nice work David!
The 1200 would be your best bet, but I believe I've read where they don't recommend lapping with the 1200. (Someone please correct me if I'm wrong).
I have a 1200 and lap with it almost daily and it's quite worn, but I've been hard on it and have used it many times on hard naturals so I expect to see some wear.
What kind of stones will you be lapping?
The Atoma 1200 works fine for maintenance lapping. It doesn't have the horsepower for severely dished hones or Arkansas. I'd get the 1200, then as resouces allow, get the 400 or 600 replacement part which is just the diamonds and substrate (no aluminum plate) from toolsfromJapan.com and stick it to the back of the 1200. Voilà, a doble sided Atoma at a discount.
Cheers, Steve
