1. All other things being equal, a larger diameter tip (and ferrule and shaft) will cause more squirt (AKA deflection).
Mr. Jewitt,
Just to clarify the above statement & avoid any misunderstanding:
Would you agree that the above is mostly only due to the additional front end weight of the larger diameter shaft?
For instance, would it be possible for a larger 13 mm tipped shaft to be drilled out on the front resulting in it having an equal or even less amount of 'squirt'/deflection than a solid 11.75 mm tipped shaft, 'all other things being equal'?
In other words, if ALL other things are truely equal such as the total weight & distribution of weight so as to make the balance points equal, would the larger 13mm shaft still have more squirt/deflection than the smaller diameter shaft?
I believe the answer is no, unless the center line upon contact is farther out & we are then getting down to 1/2 of the 1.25 mm difference in the diameters, which would be .5125 mm which could certainly be offset by a slightly different tip shape so that the contact points could be very nearly the same with the center lines also very nearly the same.
Also if the drilling out actually made the front end of the larger 13 mm tipped shaft lighter, it would have less 'squirt'/deflection than the smaller 11.75 mm solid & heavier front end shaft.
Do I have all of this correct?
Thanks in advance for you input.
Regards,
