I basically started with the Mosconi pamphlet. Cant remember what it said about ghost ball but I'm reasonably certain it was in there. What I took to heart was the electrical tape contact alignment. lol...
reminds me of darren appleton in his prime. he was a pocket chalker and also a walker chalker, with the cue dragging on the floor. hands always grubby and blue, like efren's.
i've always tried to avoid it because i like irish linen wrap
I'm probably mistaken about the shank size, i do know the straight shank only came in one size and was hard to find. This taper device worked great 12mm still fits in the drill chuck
Check out Dr V's magnetic chalk holders, strongest magnet I have ever seen in a chalk holder, had mine for at least 2 years, the pocket clip is great too, worth every penny.
than me
