What is that thing you're measuring with? Never seen one like it. What am i supposed to be seeing? How about just listing the usual cue specs? Wt., shaft size, butt diameter, balance point would be good. Nice cue.
That’s a Vernier caliper. If the pictures were taken so there’s no parallax error in the view, the tip is 13.2mm in diameter. The wrap, in the area he’s measuring, is 29.5mm in diameter.
