Thanks to Butch and Jackie.

This is beautiful if you love simple.

The pma tool with the ball measures the cone with the ball and headspace gages without the ball

Just like mine and Jackie's tool.

I thought i saw the cone shaped piece for jackies tool, not a ball

Maybe I wasn't clear. Our tool works the same only we use another tool and not the ball, it does the same thing.

I’m new to doing barrel work for myself and really think something like this would be handy. Has anyone tried the badger ordinance with the dial indicator for measuring protrusion or is this one the best to buy.

For us with machine tools we just make them ourselves.

I made one with a dial indicator i used for probably 15yrs. Id rather have the mic so i can feel it

That is a good point with the mic having a solid stop you can feel

This is mine with the cone bolt tool and HS gauge.

The cone bolt tool goes up the barrel?shaft first?

Thats the beauty of the 1” ball. Doesnt matter what cone angle you have nor if the cone is seated correctly and straight

I'm not a machinist, nor do I have the tools either, but wouldn't a steel ball work for headspace the same as on a cone breech, just need a deeper mic and appropriate size ball? Not to mention a good print for the reamer?

Exactly! Great way to measure actual headspace rather than go or no-go. There was a thread on this a few years ago wherein myself and another member derived the equation for this:

Go gauge alternative?

that cant be the Guffey Mobile-- there is to much HEADspace in there. :p

A lot of the work I do for industry has call outs using gage balls. I don't use them as a number is a number whether I use a ball or a gage. You end up pretty much in the same place. I know of one customer, not mine, that calls out ten different locations in a chamber using gage balls.

That is a good point with the mic having a solid stop you can feel

Because gages are undersize they lay in the bottom of the chamber. Out of square. One of the pluses of using a mic is it squares up the gage in the chamber when it makes contact. I get repeatable measurements to within a few tenths. Not that a chamber has to be or can be cut to those tolerances.

So using a 1 inch ball once you find the depth of the cone for a given receiver the measurement would be the same reguardless of caliber?

Its a bit more complicated than that. Think of it more like a comparator from a known measurement you previously got

Okay understand!
Can you provide some measurements for the body? I have a doner mike and could make one. Please! And how much travel on the mike.

jkohler lists some dimensions for his with pictures.

Tenon Measurement to use for coned bolt action?Update***

Hi All -- I am just wondering how to measure for tenon length on a cone bolt action? Thank You 6/6/20 -- got my remington cone bolt tenon length checker made. found out my tenon for this one needs to be .900 thats including the recoil lug. .650 threaded in action and thats ok since there isnt...

The mic is a zero to 1” and its zeroed sitting on top of the ball on a surface plate, so make it all turn out that way so your headspace measurements actually are the right number on top of a gage in the chamber. The measurement of your body depends on how much your mic protrudes on zero and how it mounts up

Keep us posted on your progress. Mine has a brown and sharpe friction thimble mic on it.
