I have a butt that is 21.5 mm, this is rougly 0.12-0.19 mm bigger than the advertised 21.31 mm to 21.38 mm joint diameter of Predator shafts, I do not have the shaft yet, would I be able to feel this once shaft and butt is screwed together?
 
Yes. Whether it is enough to bother you is arguable. The theoretical step is the same as a sheet of medium weight paper (0.004").
 
Howdy All;

We used to use a single piece of notebook paper to use as a go-no go
gauge when fitting 'flush' patches on aircraft that required a 1/64th inch
allowable around the edges. Lay it across the hole drop the 'flush' patch
in then try to pull the paper through with light pressure applied.

Yes you will be able to feel it, but it isn't in the stroke area. A cuemaker or good cue tech should be able to build up the smaller side with some clear finish, if you must have them flush.

I'd wait till you get the shaft in hand. I've seen many times they advertise a revo at 12.4 and i've gotten 12.5mm
 
fish2, Howdy;

You know the decimal equivalent of 0.2mm?
Now divide that by 2 cuz there will only be 1/2 of that 0.2mm at each edge.

Maybe, just maybe you 'might' catch a fingernail, but ... chuckle, ain't gonna make a difference.

That's funny stuff, and so small of a measurement, the error could be in your calipers. i don't know of anyone that can be that accurate or if it even matters

0.15mm is six thousandths. Calipers should be that accurate, if used correctly. It's pretty easy to be that accurate. Divide that by ten and you are into micrometer range, but still pretty easy to measure with accuracy. Divide by ten again and you are into real difficulty and lots of money.

Fyi, I have, and use a 0.2mm pencil, which is about the top end of the measurement the op is concerned about.

We aren't cutting diamonds and we are talking about that measurement divided by 2, which would have no effect on the playability of
that cue

Don't care about playability as it it should not matter, more concerned about feeling the pointy edge of the butt when I slide on my hands from shaft to butt :) ok, nobody gets weird about my comment :)

I got the shaft, I could feel a slight difference but not enough to bother me or like send it to a cuemaker to have it fixed.
