Coaxial indicators are one of the most fun set up tools there is.

Welcome, nice to have you aboard. Someone mentioned another similar but different indicator, see comment below. Has me very curious. Even the cheaper version I have is still pretty darn fun to set things up with. Lived without one for rather too long.

You know, over 50 years ago, we had a less pretty version, which was made under the trade name "Diacator" from (I've just re-learned) "Swiss Instruments Limited" Still available, it isn't as pretty as yours, admittedly...

Interesting, never heard of it, just looked it up. Thanks for mentioning it.

Have not seen those before - a very interesting tool and a simple approach to the situation. Would not be too hard to make one if someone really wanted to.

@@StuartsShed Would not be too hard... First, let's take into account the "Hierarchy of accuracy" in measurement. You want to make something which indicates within reasonable accuracy to "tenths" (0.0001", or tenths of a thou... the equipment you make it upon, and with which you measure its components, must be made with components produced to considerably tighter tolerances) Many moons ago, we were led to believe a precision instrument components must be measured using a precision instrument that was made to limits a tenth of the width of those being produced... (it's not entirely true, but it's indicative of the necessity to measure precision instrument components with more accurate precision instruments...) The history of accurate measurement in engineering is an interesting one... We've been able to gauge (different, I know...) to millionths of an inch. Microns are 40 x a millionth of an inch... The history is fascinating... and yet, you'll find places where they have jig borers and standards departments with no temperature control... I knew a guy who worked at a place making parts for submarines, on a jig borer... "constant 20C, then?" I said... He had no fucking idea... worrying!
