Thread: A littel quality time touching up the rotation on the 12K

60 to 100 should be about all you need for this venture. I picked up a pocket microscope at 200x and frankly, it's a bit much. I find myself using the tried and true 60x more often than not.

The picture in post 21 makes it look like a prime candidate for some 4k action. Doesn't look like it needs to drop back to 1k. I don't know if you read the propaganda that came with your Norton 4K, but it was designed as a "cutting" hone - it removes a lot of material for what it is. The more I play with mine, the more I'm surprised at what it can do.

You said yours feels rougher than your 1K? I didn't see anyone a dress that. They come with a fairly rough surface and this needs to be worn off with the lapping stone/plate and smoothed out. A little bit of wet sanding after lapping ensures a smooth surface. I stopped at 1k. It kind of feels like ceramic when it's ready for work. Not glassy like the 8k of course, there's a bit more friction. But much smoother than a 1k hone.
