My two original Schon shafts (1993) one of my two CC shafts, my Gulyassy SPTX and my son's Joss shaft all have zero roll...not rolled on a table, nor rolled on a rail nor spun in a lathe, together or apart. My two GEM shafts and one of my CC shaft have some "taper roll", I agree with Dick Neighbors, a roll is a roll, wood moves...that's just the way it is. The bottom line is not all shafts have to roll crooked, a good number of high quality shafts (kept in good condition) will not necessarily warp. Some will. But anyone who says they ALL roll is not being accurate.[/QUOTE]
:clapping:
Often I see the shafts itself being warped a few, mostly less than 1 mm. But the most shafts of high quality cues are without warpage and they stay unwarped although getting more or less moisture in the diffreent climates.
What I see very often and even at high priced cues (for extra I do not say high quality cues now) is that the but itself and the shaft itself are without warpage, but screwed together the cuestick is not straight 100 %. And in this case it takes not much effort to correct such little mistakes to a roll of whole cuestick smaller than 1 mm.
For my belongs I expect both of a high quality / high priced cuestick: no warpage and straight as a whole piece.
Very good and detailed information can be read on cueperfect's internet-pages to this issue of roll.
