I wonder if any of you are familiar with this old concentricity checker. I bought it used somewhere around 1980, and I think it was maybe about 10 years old then. Nicely machined out of an aluminum block, it has separate stations to spin bullets alone, or either loaded or empty brass. Brass rolls on
2 little ball bearing sheaves at the base. Nose of bullet or neck of case is located by a hollow tapered rod. All in all, it seems pretty solid and precise.

It's set-up something like the NECO tool, although it uses the rollers instead of v blocks. Also, the mount for indicator is an upright 1/4" stud, unlike the NECO, which lays down parallel.

The problem is it doesn't have an indicator. I have been looking around for a halfway decent one, and they are pretty spendy. I was hoping that some of you might be familiar with the old tool and advise me in regard to getting it up and running. The way it pilots the nose/neck seems a little shakey, but I really don't know.

I'd appreciate any insight you might have.

Thanks, Dick

.....that I bought from a friend, years ago.

I mainly use it for sorting brass by neck-wall thickness run-out, and for checking neck turning operations.

The 0.0001 indicator was with it when bought.

I'll try to post a pic.

Hope this helps....

Yep, that's it exactly... just less the indicator.

Have you ever used it to check out concentricity of bullets, brass, or loaded rounds? I have a good ball mic to keep track of neck walls, but I do need to get something going to check run out. Does your indicator show the model number?

Looks like you're sorting that brass pretty fine....

Thanks for the reply - Dick
