When it comes to testing Schuler Cues for warping, the process is a bit different than the process used for rolling a production pool cue. When checking a production pool cue, you simply lay the cue on the table, slowly roll it and watch the tip for flopping. Because of the way Schuler Cues are constructed, this process simply is not accurate. Schuler Cues feature compound tapering along the entire cue. Snooker cues are also impossible to roll without interference from construction design.
To solve this problem, we check Schuler Cues with by the following tests.
Place the bottom of the cue on the rail. Make sure the rail is in good shape. Slowly roll the cue, carefully watching the joint for any unusual movement. "Caution" - Be sure both faces from the butt and the shaft are together, there should be a clicking sound when joining together properly.
One other way to sight the straightness of a snooker cue is to hold the cue at the butt end and look down the length of the cue with one eye, like you would when you aim a rifle. Turn the butt of the cue 360 degrees, while continuing to sight down the cue. You will then be able to tell if the cue is straight or not.
