Recently a friend of mine made me a few small size cue straightness measure. I could fit it in the side pocket of my cue case easily. This is a must-have for cue dealer wannabes. Check this out:
steel races will form a grove in the finish as soon as you roll it.and the way those are built will edge cut imediatly.their is no correction for allowed taper.show the people that you plan on rolling their cues a little heart and put some rubber bands around those bearings.
great looking a few years ago i made something similar but much bigger it was made to take to shows to check shafts and butts sometimes being able to get away from our booth was hard to do and it was a way to check the cues before buying them i like your idea much smaller anice looking thanks for sharing
