Compression Ring End Gap

I had a Digital Mitutoyo with Carbide jaws for a bit, when the screen went nuts I went back to Dials.
I only have 1-2" Mics right now So, it looks like a 2-3, a 3-4 and a Bore Gauge are in my very near future. Prolly not from HF tho. Lol
A have a couple of Starrett Indicators but not a Mag Base at the moment...
Thanks Man I'll get on the Stick this week!
I love my Starrett mics, but my two favorites are a mitutoyo four inch dial, and a helios 13" dial . And an indicator without a mag base is almost useless.
The hf rec for a digital is for those of us that have nothing. Not meant as an insult to you!
