I have always cut my Nic./silver rings with a manual tool in my tool post. Curious if anyone uses their router with a straight bit to trim these? If so, what's the correct type of bit to use, A carbide? I'm already aware that the rings will heat up, just never cut them with the router, and wondering if It's possible there could be a easier way using It instead of the manual cutting tool? Also curious what others use to seal the cue before clearcote, not nelsonite, but what they seal the pores with, before final sand, and clear coating. something that will also prime the rings in the same proccess. Brand name, and type would also be of help. I am assuming answers on that would be some kind of epoxy or super glue.Thanks in advance, Greg
