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

[ridgeway]

Made this awhile ago...it gets used all the time!

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.

Seriously, that would be amazing. I would think Brownells would jump on that if you could supply them.

For those with an "over the tenon" device, can you share what depth mic you're using?

That looks amazing as well.

Is 1 inch of travel adequate ya think?

I use a 2" starrett head. Reason being I can zero the head at the tool face and take an measurement under and over 1". I can also use my cone inserts to establish length.

Starrett 1inch

I'm sure somebody has to make them.

I'll get one to have some dimensions and make life easier. But I'm liking the idea of having a couple different bodies that are threaded to fit barrels so I can clock them

I just made one in 16tpi and one in 18tpi and have marks around it with numbers. Id hate to know i had to screw a piece on a barrel every time i checked headspace- i like that slip on

 

[LVLAaron]

Agree. I might be doing myself a disservice by trying to combine two things into one.

 

[ridgeway]

BAT and Kelbly will sell you a threaded tenon to check your threads to ensure fit. Take one of those and simply engrave and index.

Did that reamer have a bad experience?

Hahahaha no, it's got a coating on it. It's my favorite reamer!

I believe my Mitutoyo has 3/8" travel. It needs no more travel.
