Just got word from Martin that he has updated his lapping guide. Here's what he's saying:
I have rewritten and added quite a bit of info to the lapping article posted a month ago. I've added a bit of a mini FAQ about sand paper along with some other odd bits of data. I believe I improved the article quite a bit.
How does it work?
The closest thing that I can think of to describe how sandpaper works is by comparing it to a saw. The sand particles on sandpaper have sharp edges that cut away at the surface just like a saw.
What is grit?
When we talk about sandpaper we reference it as XXX grit paper. This "grit" number refers to the number of abrasive particles per square inch on the paper. The lower the grit, the more particles per inch which makes it rougher. Higher grit paper has less particles making it smoother."
