Part two
The predator:
Predator has done a great thing, They answered the unsolved mystery. The shaft with less deflection or the shaft that can absorb shock. So they use a thin wall ferrule. For those who don't. Average finished ferrule size of the predator is 12.7mm which converts to .500 thousanths. Increased the tenon thickness to .404 thousanths. Subtraction equals, divided by two gives you a wall thickness of .048 thousanths.
Example
Standard masking tape is approximately .010 thick.
Predator also drill out the front of the shaft for X amount of inches. By doing this, they created a shock absorber. Shock absorbtion equals less deflection. If you think it gets confusing WELCOME TO THE CLUB. And welcome to the foundation of BASIC CUE THEORY AND PLAYABILITY OF CUES. What does the player like, Previous topic here and on Rec.Sport (Shaft Options)
I have been working on different options for shafts and giving them to players to try that use a predator. I am definately on to some thing and the feed back is positive thus far. I have nothing against any optional shaft that is offered,
