Define "Master".
Lots of people build cues. Many of those cues are not to my liking, I bet even some of the ones made by the masters. The so called "masters" may have an ideal of a cue that is way different than my own. They may very well have tried my ideas out, and then rejecting them for various reasons. Some modern methods are there for convenience/freedom of design choices (3 piece butt construction), others for stability (coring), and yet others for balance etc...I don't care about a lot of this stuff. If the cue warps, I'll straighten it or get a new one, anyway the cue will be built in the climate where it will be used, and I'll use time and good materials. I want the ultimate in playability, not a wallhanger and I don't care if it will "sell" as I'm the only customer. It will be a racing car, not an suv, all luxuries stripped off.
My idea is to build a cue for pool that plays exactly like a snooker cue, and has been built by the same methods. That is the kind of feel and control I favor. One piece of ash, running the full length of the cue, with hardwood spliced butt (and maybe veneers), obviously scaled up to withstand the increased size of the balls. It may not be very practical to transport around and is not so much new as it is extremely old. I plan to build such a cue myself, by hand planing, like the masters of old (and current, like Parris). I will use a somewhat different taper than what is favored today. It will be a long project, and I'm currently trying to source the materials. I have some ideas for ferrule materials that I don't think have been tried before, that I don't want to reveal, as well as an idea for a tenon, that I also think may be unique (but I don't care if it isn't).
What is your point anyway? Nothing new under the sun? Everyone knows that in this kind of woodworking, pretty much everything has been tried and many things rejected. The rejection reasons may not be good resons to you personally, but may be for instance about marketability and convenience, rather than playability. If a master tried and rejected my (or others') designs that may be significant, but it may also be completely insignificant to our sensibilities.
