Recommend prismatic type universal indicator stand
PekkaNF:
I'm not sure what is the real name for an indicator stand that has an inverted V on the bottom and T-groove on the flat top.
Anyways, the item i mean looks like this:

Where to get one:
1) Indicator stand that is reasonably accurate without major rebuild for normal workshop use.
2) Other one, least 250 mm long, ideally 350 mm long to cobble up some sort of bench centre:

For #1 I have seen expressions like "universal indicator stand" used, but it will bring up all sorts of magnetic bases. I need one that is of reasonable quality, not too flimsy to bend under indicator load and stuff. It does not to be completely flat and parallel to micron accuracy. Just an heavier indicator stand. I don't mind paying a little extra.
For #2 something of similar than #1, but larger. The most important thing is of approximate shape and stability. I could buy chinese/indian eBay stuff for semifinished base and mill/grind the centre stands to fit. Or buy something like centre stand and finish it myself.
On this one real ones are way too big (one was sale here, but it was like 400 kg 300€ old german one) which I have no space or very nice but not fit for my purse.
Outside TIR readings I can measure for cylindrical pieces, but taper and/or center pip/hole parts do not indicate well on surface plate/prisms.

This that sort of application I'm heading. I'm getting a grinder little closer to usefull level and I need to measure How I am doing.
So here we go: Advises, rumours, gossips or even a hint where to look for are greatly appreciated.

That's a comparator stand. I have one made by Mercer but it has tee slots both sides rather than a vee.

When you need to compare bunch of stuff with a stack of slip gage.

Yeah that's what it does.
Look up Mercer 108. There's a few on ebay one is listed as a DTI stand and the guy has fitted the stops as feet but really they should go on top to rest the part against.
