    Easy-to-remember Billiard(scratch) paths

    Hi all, I've been experimenting with Dr.Dave's peace sign and half ball hit, then I came up with these (useful?) easy-to-remember cue ball locations for scratches in all six pockets. Here is the video. It's quite interesting that on most shots the cue ball can start at exact intersection of two...

    Cue Tip Size And Shape Effects

    I didn't think of this! I guess the effort put into not hitting the table first is comparable to judging where the miscue limit is. I'd like to try it out sometime if I can get a hold of 15mm shaft lol

    Cue Tip Size And Shape Effects

    This might actually be a not-too-bad idea. Using a 15mm, or whatever size tip that allows you to hit 90% max offset. Then you don't risk miscuing and can focus more on getting the right speed.

    Cue Tip Size And Shape Effects

    on the other hand, though, we can't hit miscue limit when playing draw and therefore no max (or close to max) draw is possible. This might be one downside of having outrageously big tip.

    I'm more surprised at how someone can become an electrical engineer if they don't believe in matho_O

    Cue Tip Size And Shape Effects

    if you are used to big diameter shaft and you just started to play with 10mm shaft, sure there will be a huge difference because you are not adapted to the new shaft. You need to aim at different spot (visually)and hit the ball with different speeds to get the same action. Because the shafts...

    Improved ball marker

    If the legs are radius of the ball, I would say the blue one looks closer to reality.

    Tip Contact Location Difference between 9-Ball and 14.1

    How does DigiBall present the RPM data? Is it RPM in the axis of rotation, which changes moment to moment? Does it provide RPM in horizontal and vertical components?

    DRAW SHOT Effects Myth Buster … a Slow Motion Video Study

    I've not played with other than 19 oz cue for an extended period of time so I don't know

    DRAW SHOT Effects Myth Buster … a Slow Motion Video Study

    I haven't done this yet. Using the top edge of the shaft to approximate tip height is easy and consistent, but the actualy contact point varies non-linearly with this "tip height" because the tip is round. I might do some analysis when I got time. So far just by looking at these footage, I feel...

    Good question that I don't have an answer yet. It could be due to my counting. I'll think about this and get back to you.

    Yes the cue was 19oz. I didn't personally put it on a scale, but it was labeled 19oz when I bought it.
