Butt Taper V. Sound Quantity
Interesting you mention this. A few years ago I was looking at tone woods along with the thought that if the butt were tapered properly you'd achieve a stronger ring and ring time. The next problem is positioning/tuning where the most feedback ocurrs. Is that maybe the Node?
Anyway I get off on these nonsense tangents sometimes not knowing much at all about building a cue.
3 K,
I believe that you have hit on a very good point concerning the taper of the butt and sound quantity. Shown below is a pic of one of my cues. I am not sure if you can see it clearly butt there is a parabolic curve that starts at the butt and transitions into the A-Joint area roughly forming a trumpet type effect. This is not an offset but is a distinct arc plotted by a series of arc points when viewed graphically. When holding this cue or sighting it down it is very apparent in person. I won't get info wave propagation, laminar flow pathways, destructive interference cancelation concerning sine wave peaks. I used to be an amateur audio engineer and understand sound and how it is measured and analyzed. Don't think I used any of this when I designed my butt geometry because it was not sound I was trying to control. This is my standard taper because I was seeking to reduce the handle's physical size a tad so I designed the curved taper geometry to my permanent butt taper bar. All of the cues I have ever played with that I liked never had fat handles so I went with it. I loved my Kershsenbroch but I wanted my joint to be larger than David's.
My A-Joint is only .981 which is small by most standards I have observed but my forearm tapers down to .850 at the joint. Kinda like a counter culture or antithesis to a Southwest fat spaghetti noodle concept.
With all that being said as a precursor to your point of contention. Yes, I believe that a trumpet style taper will amplify the tone and here is why I think it's true. I fully core all of my cues with a 29" maple dowel from stem to stern as I wish to eliminate the ring tone of the exotic wood combos so my cues are very quiet and play and feel pretty much the same from cue to cue no matter what combos I choose. Just the way I do things and the way I want my cues to be known for.
The last A Joint cue I made was several years ago and it was the first and only A Joint cue I made with this trumpet style taper. When I hit with that cue I heard a very noticeable ringtone that I believe was from this amplifying geometry of the taper as I had made about 60 A Joint cues previously and was accustomed to the way my cues sounded in general.
How loud was it? It was so loud that I had to put ear plugs in before my next shot fearing OSHA would fine me for noise pollution. :nanner: No seriously, to me it was very noticeable but of coarse this is all subjective concerning cue ring tones. On this one you will have to take my word on it, :duck:, but if you experiment with this type of taper you may be surprised.
For all of the CMs who prefer the noticeable audible feedback in their cues this may be something to try.
JMO,

PS: If any other cue maker friends who like Ping in their fine cues made with great ring tone materials wish to try this type of taper. Send me a cue blank about .030 over .850 / 1.250 size finish and I will take the last passes on my butt taper saw machine for you and nail your desired joint dimension for shaft line up an fit. Of coarse you will pay the shipping back and forth and buy me one deli sandwich for $ 6.00.
Here is a new cue I just finished. I don't know if you can see it in the pic but the bunny rabbit has the right angled view. The curve starts from the butt to about the middle of the handle before there is a more conventional butt taper climb from the joint to the transition area in the handle. Joint .850, A-Joint .980 and Butt end 1.254.
The butt taper is fixed on this machines bar. If you wish to see if it makes a sound difference just PM me and I would be happy to do it for a deli sandwich from Capri Deli. Plus I would get CM feed back to share info from anyone who wants to experiment.
