Because of the misunderstandings that are rife in the Billiard industry regarding cue straightness, we have created this page that is an extension of our Returns Policy to better explain the Quality Check Standard that we work to.
Because a 2pc cue has 2 different sections, the variance can be checked in 3 areas
- Top Shaft
- Bottom Shaft
We check cues both before we apply a design, then check again & document the results before we send them. We aim for zero to insignificant variances.
Insignificant variance – refers to a minor variance that would have little or no effect on the playing quality or accuracy of the cue. (For instance – A straight top & bottom shaft with a joiner variance of 2-3mm equates to an accuracy adjustment of less than one-tenth or <0.3mm)
HOW TO CHECK A 2-PIECE CUE
1.) Visual Check First – Lift the cue up to your shoulder like a rifle and look down the barrel. Rotate the cue while looking down it.
- Top Shaft Warp – Is there any significant bending to one side in the top third of the top shaft leading to the tip? Mild shape variance over the whole top shaft is acceptable.
- Joiner Variance – Can you see a significant change in direction from the bottom shaft through to the top shaft?
- If there is nothing significant you can see, there is no need to proceed with any more checks. Your cue is straight.
2.) Top Shaft Roll – If you believe the top shaft has a variance, remove the top shaft & roll it.
- Does the tip lift from the table indicating a hook to one side.
- If you believe that the top shaft doesn’t hook to one side but has a significant shape or taper problem, to be significant the shaft will have a visual inconsistency in how evenly it rolls.
Remember – the roll doesn’t have to be perfect. There is no game played where the cue is rolled around on a table.
3.) Bottom Shaft Roll – Remove the bottom shaft & roll it on the table
- Unless there is a significant bend to one side, shape variances of the bottom shaft don’t have any effect on cue accuracy
- The reason it is checked is because even a slight bulge or uneven taper in the butt can cause uneven rolling when doing a full length roll.
4.) Full Length Roll – This is only worth doing if you have completed the first 3 checks. Otherwise is has no context.
- If you’re top shaft is straight & you are taking into account any shape variance in the butt section, any variance you find here is a joiner variance.
- It’s not hard to understand how 2 long thin pieces of timber joined together over 57 inches can have a tip lift of a couple of mil.
- This effects your accuracy by a factor of 1/10 & can easily be adjusted with a bit of pressure in the opposite direction to the lift.
- Variance in the top third near the tip must be less than 1mm.
- Is allowed to have a shape variance, which refers to the taper or shape of the shaft as long as it is 1mm or less for a 9 – 11mm OR less than 2mm for a 12 – 13mm.
- Is allowed to have a shape variance as long as it is not significant enough to affect cue accuracy.
- If your cue has a straight top & bottom shaft, the tip can lift we accept is 1mm or less when we send it.
- If it is more than that when you check it, there are a number of reasons from 1.) tightening the joiner correctly to 2.) debris in the joiner area to 3.) the tiniest contraction of the timber.
