Thread: C12k questions

Hi all. I've been lurking and reading a lot here for a while, but just recently joined.

I'm interested in the Cnat at Woodcraft, but have a couple questions. First, from what I've read here, they can be a bit hit or miss. Is there any way to discern a good one from a bad one if you go to the store to pick it out? Second, how do you lap one of these? Thanks.
