If you can simply "insert" the 23 rollers and have no play in the shaft or have no binding of the shaft you should be good. Tapping in a roller is a BIG NO

Yes, and when the professional machinists talk about ten thousands of an inch they shorten it to "tenths". So they would call .0006, "Six tenths." Which of course causes confusion because .6 is really 6 tenths of an inch. They would probably call .6, 600 thousands. Same value.

So machinists are too lazy to say "ten thousands of an inch". and everyone doesn't know what they're talking about. Damn machinists.

Tenths.
.0001 One tenth

One ten thousandths of an inch

I was questioning the accuracy of the measurement. Not trying to be a d*ck, but that is damn small. Temperature will affect it

I think we pretty much all measure parts in our temperature controlled clean room.

I run mine at 75F and 50% humidity*, Others may prefer other settings.

As long as you stabilize everything before you do the measure or cut you'll be fine.

* - my carpenter recommended this to me. It's what he uses.
