Headspace in Lathe - Depth Mic, Dial Indicator, Or??

[Machinist John]

To Dave-- thank you for all the help. i have appreciated it-- i did find an interesting article as i was looking through some back issues of PS lately

I would to have a copy of this article. Way back I received PS, even had two articles published. But gave it up when I retired.

Any takers? I will pay for your effort.

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.View attachment 1378597View attachment 1378598View attachment 1378599View attachment 1378600

I'm a little late to the party but this is the tool I made for measuring headspace about 15 years ago.
Take a measurement off an old barrel and zero it then you've got a zero to work to on the new barrel.

An old pic of my tools. I have one with 16tpi and 18tpi. Mine screws on and I use the headspace go gauge and I actually have 2 of the little valve looking tools with different angles to measure bolt nose clearance. Write it all in your little black book and you will never need the receiver when chambering another barrel. The 12 vertical lines on the OD lets me line up the lettering on the barrel so I can mark the new one in the same location.

I also made one that screws on but relieved the front part of the thread so it's approx. 3 turns on a Nesika tenon.
I need to mark mine like yours so I can index the barrel markings.

Another couple tools that I use are the inserts that thread into a Panda and a Stiller Viper. Although the TPI is the same, the pitch diameter is a little different. Beside being a thread check gauge for those 2 receivers, the right one works with the Bat and Borden. Nice to have if you are chambering a glue in or do not have the receiver in hand.

Now see? THATS the kind of stuff someone should be making for gunsmiths.

Have you got a pic of those?
That sounds like something similar to what I've got for measuring a Teddy.

Panda insert has the same thread and PD of the Teddy.

Must be the suspenders that give it away.

I'm planning on making one that's got marked degrees all the way around it - So I can time/index as well, without having the action.
