very nice! What material did you use? I made myself a 30mm bar a few years ago, from a piece of 304ss I had laying around

It's aluminum. I won't be using lapping compound. The diameter is 0.016" undersized to accommodate the thickness of 600 wet/dry paper. The knob is ebony, I'm sure that's the key to accurate scope alignment

Why do you feel you need to lap these particular rings?

I'll be putting Talley lightweight scope mounts on a defiance anTi action. I expect the rings and action to be aligned pretty precisely but I want to be sure. Here's a previous lapping job I did for 30mm Talley mounts on an x-bolt.

Love it , great job, want to head out to my shop and make 2 a 30mm and 34mm alignment tool with a center ring and the lapping bars also, do you have the O.D. of the lapping tool you made, is it just 34mm or 30mm? or smaller by a few thousands ?
