Ready for gapping the rings. (Hopefully next weekend). Always too cheap to buy the right tool for the job, I put my angle drill in bondage to make my own ring grinder. :boggled:
The nylon rings that are screwed to the base, hold the ring square to the grinding wheel and the high-end lamp :rolleyes: helps me make sure it is. I also bought a 6 x's magnifying glass that I'll use to make 100% sure the ends are ground square.
Currently the top rings are gapped 0.012 and the 2nd rings are 0.014. I plan to open them up another 0.010.
