That looks like a Diatest indicator, but what is all the other junk?

Looks like a bore gauge with some kind of outer depth stop?

Edit: oh I see it now: It works perpendicular to the bore and the "depth stop" is the other side of the indicator. Looks to be adjustable for bigger pieces>

Dunno it's just a Bore Gauge in that regard, just a different approach to it.

That is awesome!
I need one
Would love to get out of the stone age

How is that supposed to work for measuring bore diameter?

Horseshoe and micrometer catridge?

No need to spend a fortune for a special tool. I used a spring caliper with a test indicator mounted to a modified leg as an "over the bar" bore gage for ages. Works great and only costs a little time if you already have a suitable test indicator and a spring caliper of the correct variety.

There's one on e-bay right now-

Mahr Line Boring Internal Measuring Gauge, Range 1.5" to 4.5" | eBay

Did not know that I had to clean up the area to take a photo nor get a decent response.

Thank you gentlemen !!!! Appreciate your knowledge... You know who you are..

You set your wanted size to zero on the indicator on the device with an outside mike. Then as you slide it into the bored hole, you read the dial as either plus or minus in the 10ths.. If you are over, plus, you missed it. Sorry. Under zero, dial the cutting bit out to half of the reading and take the cut to size. Interesting tool.
