[QUOTE="xcvator, post: 566272, member: 8322"] Couldn't/didn't see any cracks before I started. 80 grit, then 150, then 320 and I stopped when I saw all these cracks appearing and bits breaking off of the edges. Were they there all along ? Did I get them too hot when dopping ? Hot enough to keep the wax soft for a minute or so. They didn't feel even warm when grinding them Do I need to get a very strong magnifying glass to check for this sort of thing before starting to grind stones ?
