What is the correct way to store my cues?
Also, what is the plumb line method of checking straightness?
With all due respect,
Tim
Agree with those who recommend a good case, and storing the cues upright. That way there's no sideways pressure on either shafts or butts.
I mentioned plumb line for butt only, because it's hard to tell by rolling it on a table. Slate is not milled perfectly, and eyesight is not perfect either.
Technically a plumb line is a string or thread with a weight attached suspended in the air, to tell whether a lower line or surface is perpendicular, or off at whatever angle. In this case, a plumb line would be fine string or thread looped around the joint pin, down the center of the joint, then stretched down to the center of the end, or bumper, and secured. Best to secure the butt in a vise with towel to cushion it if you want to try. It's actually more valuable to tell if your points and inlays are really centered, but you can also test the overall straightness of the butt. Take several points on the butt, and measure with calipers to each edge of the cue from the thread. Exactly equal measurements on each side of the line equals a straight butt.
Probably not a big deal in most cases, especially if your assembled cue is rolling pretty good, with no wobble, or minimum wobble, and you are pocketing balls fine. But it is brutally revealing in examining just the butt, for information.
All the best,
