What's next? ... Your center of gravity betrays you and you start falling over, and not just when playing pool.

I believe that a good starting point would be to pivot the cue at the 18" mark, so the pivot point stays on the shot line. This will require both front and back hand english. This video may help, but you may want to invoke the mute button:

In looking up coefficients of friction for leather (https://www.engineeringtoolbox.com/friction-coefficients-d_778.html#gsc.tab=0) it is seen that leather-metal has a coefficient u=0.6, which is within the theoretical neighborhood of what is needed for no-miscue. It makes me wonder if spending...

Interesting that they intentionally play with generous mushrooming of the tips. I wonder if this is because... - They want a larger striking area without increasing the shaft diameter, or - The unsupported tip edges have "give" that somehow improves the tip-CB interaction - They...

You are probably correct that pros don't put conscious thought into pivoting. It has been my observation that when using english, they are very consistent in having the same location on the shaft crossing the shot line, regardless of what the front and back hands are doing. My guess is that...

That is a good question, and one that I don't have the answer to. Are LD shafts more forgiving if there is error in choosing the point you pivot the cue around? I don't know, I'm waiting for someone to do the experiments on this. In the meantime I will stick with a maple shaft that has a 12"...

A diagram of this would be helpful. Could go in the aiming sub-forum.

What is missing here was supplied by Dr. Dave (see snip below from TP-B26): If you have a cue with a pivot length that does not match bridge length, you still pivot the cue around it's pivot point, but must use a combination of FHE and BHE. So for an LD shaft with the pivot at 15", the pivoting...

Suppose you have done all the alignment, feathering, and associated CB-OB vision transitions. Then you move the butt of the cue to apply BHE. The line of the cue no longer connects CB center to the aim point. I know the pros do this all the time and maintain focus on the OB. But would...

In a short you tube video, Alex Pagulayan states his case for CB last. It appears to me that he is advocating this more as a learning tool, rather than "this is how the pros do it."

Millimeters work well. The top image is a 6mm, the lower about 13mm. Knowing that gearing english (in mm) = cut angle(degrees)/5 you can actually do something with it.

If he is a cheat, then pass. If he has a disability that prevents normal use of the bridge and is just trying to stay in the game, then I would do it. But only if he is a decent type. Any advantage gained from using it would be minimal. Does it meet WPA specs? I would say there is no specific...

Thanks for posting a good instructional podcast video. However, this one, like all other stance instruction videos that I have seen, is missing an important element: The "perfect stance" is only applicable to about half the shots that you will encounter. For those of us of average (or less)...

Ah, the center to edge epiphany.

From a logic perspective(outside of the pool hall) AND implies that both conditions need to be satisfied, while OR means only one of the conditions needs to be met.
