If they have a variance of .002", you will miss the 9-ball about 33.333% more often.\
Aftermarket shafts have .840" joint size or so.
Cues fall around .835 to .860" joint sizes.
1/16 is way too much size difference.
It won't affect playability but it'd look ugly imo.
How important is it for the shaft and butt to be the same size? Will small differences in diameter of about 1/16" affect playability? I bought some aftermarket shafts that are a bit smaller than the butt.
How does the edge come into play?Here's another option, one that I quickly acknowledge would be rejected by most people.
If the joint diameters are considerably different (shaft vs. butt), the main problem to me is feeling the sharp edge of whichever one is larger. I had a butt and shaft I wanted to use together, but they differed by about 30 thousandths. This created an annoying edge when they were screwed together. The butt was larger, so I just beveled (at about 45 degrees) the edge of the butt's joint face slightly until the inside (smaller) diameter of the bevel was approximately the same as the diameter of the shaft. Annoyance gone.
