Hey all,

So I'm getting the full set (500, 1000, 2000, 4000, 8000, and 16000) of Shapton stones on glass and the idea of lapping them to perfection is driving me crazy. So my question is, would 15 micron (approximately 1000 grit apparently) be too fine to lap the Shaptons with? I have a local hardware store that sells a granite surface plate: Granite Surface Plate - Lee Valley Tools for a decent price, and it's flat to 0.0001" (about 2.5 mircon, a little flatter than the DGLP, ok, BARELY ). I was thinking of using it with this: 3M Micro-Abrasives for Sharpening - Lee Valley Tools, the 3M micro-abrasive sheets.

I like the idea of getting an exceedingly flat granite surface plate since it's a known extremely flat surface, but also because I can use it as a lapping surface AND for a honing surface if I decide to try honing with micro-abrasives. It'll be a LOT cheaper than a DGLP, and I can use it with multiple grits and uses.

Anyways, let me know what you think. I'm going to go pick it up now anyways, I just wondered if anyone has any feedback on it. Thanks!

P.S. Please don't suggest a DMT D8C for lapping, since I already have one. I know i'm being OCD about this, but that's ok, it keeps me busy.
