I'm VERY pleased with this new lapping system and it was a lot cheaper than buying a Shapton lapping plate. The only drawback is that I have to buy 3M microfilm when I run out.
Anyways, I now have a coticule that's flat to within 0.0001" mwah-ha-ha. I look forward to using it on my Shaptons. ChrisL, I will indeed use my DMT to initially lap the Shaptons as I would imagine it would take a long time on the 15 micron paper alone. But I will keep the granite plate and the 15 micron sheets handy for re-refreshing them.
