I made this several years back but I like digital for the simple fact that zero'ing it out is a touch of a button.
Headspace in Lathe - Depth Mic, Dial Indicator, Or??

Flush is the cat's meow. I made my system about 1994. First time I used it I said Wow! Should have done this years ago.
Similar to some others here...from Mr. Tooley's suggestion. No rocking of the depth gage on the go gage- precise measurement of gage protrusion. Sized to slide over tenon and seat on the shoulder.
This gives total dimension shoulder to gage, so just subtract tenon length. You could machine a smaller cylinder to seat on the breech, to direct read the gage on a nutted barrel sans shoulder.

I have an old depth mic i cut one side off of that i use when im not using the 1” ball and mic setup or the dial indicator that slides over the threads. The depth mic with one leg cut off works very well
Could you post a pic of your tools when you get a chance? This thread has become a very useful info source for measuring headspace on a lathe.
How do you use the DRO? Are you putting the cutti g tool against the back of the head space gauge?

Yes.
Best way would be using an indicator mounted to tool post in conjuction with the DRO. I measure with my cone/headspace tool. Used to use the collar and depth mic before I made a gizmo.
