Predator Z Shaft

My Predator Z Uni-Loc shaft arrived tonight. In case anyone's
interested in the "European taper", here are some shaft diameter
measurements with the same for comparison to my standard Dale Perry
Uni-Loc shaft:

(Inches from collar)  Z(mm)     %       STD(mm)  %

collar length   9.25mm          10.75mm 
                                
ferrule length  12.75mm         25.25mm 
                                
overall length  29.10 in                29.25 in        

It starts out fat, and tapers quickly in the 3-6" range. I'll get to
play with it Thursday night...
