Going out tomorrow for a flintlock day with my club. I was swapping out my flint and thought I'd clean up the face of the frizzen since it was getting pretty chewed up. Ran a Dremel drum sander over the face to smooth and blend the little worn hollow and restore a nice smooth sweep. So far so good. Cocked and triggered the flint to check on sparking. Not a whole lot but it may be the flints I've got. But more worrisome was the fact that the flint must have chattered it's way down the face. There's one mark where it first hits then a gap of darn near 1/4 inch then 5 or 6 little mini strikes that are spaced about 1/16 inch apart the rest of the way. Hints please? Or is this pretty normal? I'll have to muddle through tomorrow but I can't help but think that I'd have a bigger shower of sparks if the flint stayed in contact with the frizzen all the way down.
