I would like to make some 30 mm to 1" brass scope rings. Turning the O.D. and I.D. is not an issue. Once the rings are made I have to slit them across the middle. I was thinking of using a slitting saw. Would this be the best way to slice the rings? Also I am assuming that if I use a 1/32" slitting saw I have to adjust the finished OD and ID to compensate for the kerf of the slitting saw. Also what would be the best way to hold the ring in the vice to get an exact middle cut of the ring?
Thanks
Joe
