Is there a gap in the billiards club table that is not straight?

"Rolling the table" means putting the club flat on the table and rolling the club to see if there is a gap between it and the table mud. This is the most intuitive way to observe the bending of the club. The reason why the manual lever rolls on the table is because there is bound to be errors in manual grinding. The club is a cone, and the gradual change of the thickness of the manual rod from beginning to end cannot be absolutely linear, which leads to the manual roller table being less perfect than the mechanical roller table.

The straightness of the club will affect the accuracy of hitting the ball, so it is very important to keep the straightness of the club. If you find that the club is bent, you can try to wipe it with a wet cloth and heat it with a hair dryer to correct it.
