I was helping a buddy of mine with directional and rotational throw and some tangent line stuff. A couple of months ago I saw a video/link where someone used the actual cue joint to visualize the tangent line. Since then I have done the same.
Anyway as I was explaining the tangent line to my friend I noticed something else. My joint and joint collar on one side is EXACTLY 1 1/8 inches. I suppose this could also be used to show a more precise ghostball location is one wanted to do so.........
