Concentricity Gauge build

[dragon813gt]

Quite impressive. Makes me wish I had the tooling to build my own tools. I have a Forster concentricity gauge. Use it mostly when converting brass to see what the necks end up at. I have used it to check run out of loaded rounds. Much to the chagrin of many, Lee dies typically yield the lowest. I'm not a Benchrest or long range shooter so it's not critical for me. Obviously I want to make the most accurate ammo possible. Just haven't found the need to correct every little aspect.

I like yours for sure, but the second one is impressive in its simplicity.

jmorris you have done it again! Very nice work. Your post reminds me of the New Yankee Workshop. Of course Norm is a master cabinet maker, carpenter, etc. He builds some beautiful stuff in his short 30 minute program. Problem is my wife wonders why I can't build something like that in 30 minutes. Gives me fits. Norm will say "I got to the shop a little early and got this ready for finish".
jmorris, please continue to let that fertile mind of yours work and show us normal folks what can be done with the right tools, and a bunch of experience.

I made my concentricity gauge using high quality skateboard bearings and some steel odds & ends I had laying around.
It's still in prototype stage and so far it works real good. All that's left to be done is to get rid of the clamps and find a base mount it on.
