Zero. I just never imagined the sound of the cue made any difference. Usually it's pretty noisy to begin with.
Ivory ferrules impart a unique sound to the stroking of a cue ball. It has a higher ping sound that is very distinct.
Aside from the obvious acoustical difference, it also exhibits a softer feel but obviously the tip hardness matters.
As far as Kielwood or Roasted Maple shafts are referred to as lighter, that refers to the front end mass, coring of
the shaft and kiln roasting to extract moisture, sugar, etc. That obviously lowers the weight of the shaft somewhat.
In regard to the shaft becoming brittle, I’ve never seen that….yet. One of the steps in making a Kielwood shaft is the
reintroduction of moisture to the shaft as part of the process. Cue makers do understand the importance of durability.
Kielwood shafts tend to weigh 3.4 to 3.75 ozs.but the shaft diameter and taper length do influence the shaft’s weight.
It is pretty obvious that a 13mm shaft with a 29” length should be heavier than that same shaft built in 12.5mm diam.
I have preached about shaft weight ratio since I joined Az awhile ago. Not everyone pays attention to the minutia of
cue making as much as myself. You can make a shaft heavier by adding 1/2” to 1” length that doesn’t affect your cue’s
hit. A 29.5”or 30” shaft on a 29” butt plays pretty much like a 58” cue (29”/29”). I think that Kielwood is more durable
than a maple shaft, exhibits less deflection and at the right weight ratio, is a blessing for a player that likes wood shafts.
My Barnhart shaft is 29.5”, 12.85mm, pro taper, 3.81 ozs. I’m hoping the KW shafts being made for me turn out over
4 ozs., 12.75mm and Jacoby’s std pro taper of 19”. Tony said he had some wood that seemed well suited to building the
heavier version KW shaft I want made. It wasn’t easy finding anyone to tackle this but along the way, I encountered a few
cue makers that said they could build what I wanted. Most of the cue makers I contacted shied away from tackling this.
If you are going to get a cue built with wood shafts, do yourself a favor & substitute Kielwood shafts for original maple
shafts. You don’t have to subscribe to my school of thought, re: shaft weight ratio, to enjoy the benefits of a KW shaft.
