made q for myself years ago.first time i made one with ivory joint.had a horrible hit. i mean real soft and bad . changed ferrule twice and several tips. a customer gives me his shaft for a new tip on a cue i made for him. i screw it on my butt and a great hit.i know,i only made one shaft my own cueand as a q maker i should definitely have made a second shaft.but i didnt. i eventually ran the shaft through my bandsaw thinking maybe there was a void,but it was solid . anyone see this before?ive asked many well known cuemakers and no one knows why?by the way, no insert,radial pin
