Concentricity gauge bed

Thoughts on this. Just picked it up on ebay. 25 bucks SS rails, pressed in bearings.

Looks like it should work as long as you have a solid and flat surface.

I'll secure it to a piece of wood and clamp it in my bench vice. I have a Harbor freight magnet indicator stand behind it.

Simple is effective. The only issue you may have is the pressure of the indicator making the nose of the cartridge bob up and down as you rotate it with your fingers. I would take and old wooden ruler or something similar and put a big rubber band along the edge, then you can get several rotations of the cartridge using the ruler like a bow on a violin.

I use glued popcicle sticks with a rubber band.

Looks good to me, never really liked the hornady that I use

You can supposedly straighten a bullet. That does not work.
Bearing surface is rim, I don't think that is good. specially the ones I've just ripped chunks out of.

without rims damaged how is it?

 

[pdog shooter]

Cant prove it, but I believe rims are not concentric.
Hey, put some brass on your tool with gauge riding on rim, lets find out.

That's why a test indicator is better in this use than a dial.

That's a similar idea to sinclairs.And mine showed much more spread than my friends Hornady testing same cartridges
