Thread: Would you run these cams?

Don't actually use a file unless you have a really fine file like those diamond or carbide impregnated ones. Use emery cloth of varying grit until you get down to the least abrasive, then polish if you're up to it.

Emory cloth ONLY folks, File is too agressive. Also your your hands, do not try and just put it a block of wood and sand it. Just want to get rid of edges.
