My question is this: what degree of accuracy is it reasonable to expect of
cuemakers and the equipment they use to create the uniform diameter portions of
professional taper shafts?
Three months ago I purchased a cue and just couldnt seem to hit as
consistently with it as I could with a number of other sticks.
After two months of frustration I made two observations: 1) the grain looked
sorta wavy to me and 2) the shaft diameter along the first ten inches (as
measured from the ***end of the ferrule) was not uniform. The manufacturer,
who referred to the latter variability as a coke bottle effect, remilled
(not replaced) the shaft without argument and returned it to me today.
I tried it out immediately, with disappointing results.
So, harking back to my earlier experience, I took a closer look at the shaft.
The diameter along the first five inches (again measured from the ***end of
the ferrule) is about .2 (two tenths of a mm) +/- .1 mm greater than it is
along the next five inches!
I realize the greatest variability is within me and not the shaft.
However, for two reasons I suspect greater cuemaking accuracy that this is a
reasonable expectation. First, players seem able to distinguish between shafts
of 12.5, 12.75 and and 13 mm. Second, I just noticed this evening that
cuemaker Judd Fuller is quoted in this months Pool and Billiard magazine (p
58) as measuring the outside diameter at the ***end of a cue to an accuracy
of thousands of an inch (1.240 inches) which would be, by my calculations,
equivalent to accuracy at the .025 mm level.
Still, Im no expert, so I ask those who are: what variations in diameter
throughout the first ten inches of a professional taper shaft are acceptable
to the cue makers who read these exchanges?
