    Pool & Golf?

    What do you think of a pool hall with an adjacent golf simulator room? Synergistic cross-attractions or totally different clientele? Which is better? Asking for a friend. pj chgo

    Carbon Fiber vs Maple - Density and Squirt

    Just because I was curious, here's a simple diagram of the cross sections of two 12mm shafts, carbon fiber and maple, showing the thickness of CF walls needed to equal the mass of the equal diameter maple shaft (for CF that's 2.5 times as dense as maple, which Google says is more or less...

    Name These Overlaps

    Saw this on Facebook and wondered if you see it like I do: except for the “full”, "1/2" and “thin” hits, I think they’re backwards - the fraction should describe the amount of overlap, not the amount of “revealed” object ball. pj chgo

    Pocket Facing Angles - Why Not Parallel?

    Pocket specs say the back (throat) of the pocket opening should be narrower than the front (mouth), apparently so the pocket will reject some balls that hit the facing at the "wrong" speed/angle. My question: the ball has to get past the mouth to hit a facing - why isn't that good enough? pj...

    Measuring Pics of Pockets Using Balls as "Rulers"

    There's been a lot of discussion about pocket measurements lately, so I thought it might be useful to show how they can be measured from a pic (if it's not too distorted by camera angle) using the balls in the pic as "rulers". These are corner and side pockets from VP4 - ball "rulers" are...

    Is "Feel" Essential for Successful Aiming?

    I've always maintained that there are too many different cut angles* needed in pool for any usable aiming system to possibly "define" all of them so precisely that any shot can be made by following the system's instructions to the letter, without the need to recognize the final aim solution...

    Best Spots?

    Is there a "best" kind of foot/head spot to put on a newly recovered table? Something that will last, not cause rolloffs and be easy to remove and replace? Looking for suggestions for brand, material, installation technique, etc. Thanks in advance, pj chgo

    LD CF?

    CF is about 3 times as dense as maple, so to make a CF shaft that deflects (squirts) less than a solid maple shaft of the same diameter, it must have less than 1/3 the cross sectional area of the solid maple shaft at the tip. That means for a 12.7mm (1/2") shaft the CF version must be hollowed...
