A group of us use to play 1-15 8 Ball or as we called it "Alabama 8 Ball" with rules that lead to a strategic and nuanced game. Alabama 8 Ball (1-15) The rules for 8 Ball established by World Pool-Billiard Association (WPA) with the following exceptions and modifications should apply to...

The track marks on my table when doing the Mighty X were due to chalk. I was able to vacuum them out.

Ha Ha Ha oh yes the old Coriolis effect, maybe throw in some earth wobble as well. Exactly my point, bridge length/cue elevation can vary from shot to shot, thus the problem with DD SAWS method. BlackMamba asked why his calibration was failing and my guess was probable due to varying bridge...

I think Dr Dave's SAWS method will give you a general guideline/understanding of where cue ball might end up when hitting with side spin. You should understand all of these calibrations will change with bridge length, elevation of the butt of the cue, cloth condition, humidity, rotation of the...

Rocket, You may want to view these 4 Youtubes. They were a great help in improving my stroke.

At $199.00 I decided to try out the Rhino 12.2 mm. I have had it for a month and when it comes to squirt compensation, I think I like it better then my Predator Z shaft (plus I don't have to worry about dings). My Rhino, with a natural pivot length of around 15," better matches my bridge length...

You may not be aware of this but actually there is a lot of stuff that happens when you hit a ball with a stick. You may want to cuss Gaspard-Gustave de Coriolis, a Frenchman no less, that wrote a book, way back in 1835, named Mathematical Theory of Spin, Friction, and Collision in the Game of...

Why bother. Why bother knowing the weight of your cue, why bother knowing your cue length, why bother knowing the diameter of your tip, why bother knowing the hardness of your tip. Why bother. The natural pivot point (NPL) is just another characteristic of a cue that one can measure to gain...

I found this YouTube video “Demystifying Front Hand English” on Dr Dave’s website https://billiards.colostate.edu/faq/sidespin/bhe-fhe/ that better explains my original post. Thanks Dr Dave

I agree it is a beginning to Dr Dave's SAWS method. His method covers pretty much everything using side spin and is far more comprehensive than what I presented. However, l am a numbers guy and he uses a lot of percentages in his method and I needed a point to start. Also, I have not seen it...

BHE - Back Hand English Where you pivot your back hand holding the bridge stationary to put spin on the cue ball. FHE - Front Hand English Where you move your bridge hand to put spin on the cue ball. NPL - Natural Pivot Length https://billiards.colostate.edu/faq/cue/natural-pivot-length/

On the use of BHE and FHE, my theory is that unless your bridge length matches the natural pivot length (NPL) of the cue you must use a combination of BHE and FHE to bring the natural pivot point into the aim line of the shot. This is especially true for my Predator Z shaft with a NPL of 18” and...

If you are going to review a low deflection shaft why would you not test for the natural pivot length. I think that is a better indicator of the shaft's deflection than his deflection test and would give the viewer an indication how well the shaft would match his bridge length. I could be wrong...
