ring boring jig.

Sometimes I use fiber rings in black and white but I bore the buttsleeve out to.900. So I made this jig to hold up to eight rings. I touch off and run the boring bar through and I have an id of .900. Not for sale, it worked so well I thought I would share. It took about an hour to make. Hope this can help out anyone doing the same thing.
Thanks
Robert Harris

ring jig

Thanks Bob, I had some 2 inch round stock and didn't feel like turning internal threads so I just capped it and used 8/32 weight bolt screws for the compression of the rings.
Thanks
