Hello,
in this forum I am a new member. Before I have been in a german billards forum for one and a half years. I like playing pool, and not less I am interested in making cue repairs for my friends and fellows of our billard club.
In last times I more and more think about starting to build cues by my own. By experimenting with used butts and shafts I've tried to get a feeling about the direction of the kind of cues that I may build sometime.
A question that I try to understand and where it is impossible to discuss in a gentle and objektive way in that special german forum, is the question about how a low deflection cue "works". What is it that makes a cue producing low deflection.
I read some articles of "Dr. Dave" who is for sure well known for most of american cuemakers. Am I right?
Dr. Daves articles that I read tell, that deflection or "squirt" depends on the so called "endmass" of the cue. The idea of this theory roughly is that especially at the area of the tip and some inches behind at the front end of the shaft the mass or partial weight of the shaft is the factor the decides of having more or less deflection.
I have searched but not found some continuative or alternative theory or meassurements how the stiffness (the flexibility and the bending line) of the shaft's front end or of whole cue stick affects deflection.
I hope that the specialists of this forum can answer this question much better. In my theory the flexibility, especially the way the front end can flex while contacting the white ball is affecting the deflection mostly. In my "opinion" the most important reasons for more or less deflection are both: stiffness of front end and the mass of the front end. Secondly the stiffness of the whole shaft maybe important also. May be it is the relation between static stiffness (or static bending line under a certain applied load that erases while contacting the white ball) and the end mass. The higher the end mass, the higher deflection. The stiffer the front end and the less flexible he front end, the higher the deflection. The stiffer the whole shaft, the higher the deflection. Roughly spoken. This would also explain that the butt and joint also affects deflection, but less as the shaft itself.
I would be very thankful for getting some feasible explanations from the experts of this forum.
With my best wishes
Michael
