Hey there Paul! I hope you had a great trip!
First, thanks very much for the extensive and broad response....putting everyone's thoughts together on this topic, I have to take a step back to comment on the collective wisdom and willingness to share that is on display here...it's deeply admirable, singular, and frankly, priceless.
Now, I've up to this point ladled sugar and cream on all my posts and loudly advertised my ignorance, genuine and deep respect for the whipmakers here, and personal capacity for stupidity. I've provided caveats and disparagement to my own ideas and approaches. None of that, however, seems to have ameliorated the prose in contest to my proposition, which I think indicates my attempts to question without stimulating personalization reactions failed. Add that you are Paul Nolan, the biggest, baddest dog to bark my direction, that I've dealt with you quite a bit and hold you in the highest esteem, and that you've toolshedded me (

) ), I'll think I'll dispense with the surgarcoating this time.
I concede your point on the value of other resources such as the AWPA, and I've read volumes from their whipmaking forum along with other material from relevant forums (turk's heads comes to mind.) Whipmaker's personal sites and blogs can similarly provide excellent information, as of course do the Morgan and Edwards "bibles" and lesser know books like Dennis Rush's
Whipmaking , etc. I further concede that the "whip-inside-a-whip" design is in all likelihood an improvement over older designs (and vastly so). Finally, I concede at least the partial applicability of Darwinian evolution by natural selection to whipmaking and current design consensus.
However..
You propose (1) that the occurance of ongoing, in-depth whipmaking discussions and debate between highly skilled professionals demonstrates evidence to support the superiority of using bolsters. You also suggest (2) that the broad dissemination and acceptance of the whip-within-a-whip, bolstered design, i.e. that a large majority of whipmakers learned and embraced the approach, ADDED to the fact that it's changed little in a century, provide further evidence of it's superiority. You also state (3) that studies of whip construction have, in fact, occurred, ("...it has very much been done...") and that reason, not dogmatism, rules.
All of these beliefs are false.
Discussion and debate (point 1) has clear merit, has no doubt been an important driver of real progress, and provides absolutely no evidence whatsoever. Opinion, when not supported by tested evidence, is not proof, however informed and valuable, period. Asserting opinion where tested evidence is required is a non-starter. Duration (point 2) of a steady-state in whip morphology (~100 years in this case) sounds impressive, but concluding it therefore proves that an apex design has been achieved requires dependence on untested assumptions, circular reasoning, and ignores other possibilities. It
may be that an apex design has been reached and so we see no further evolution. Or it may also be due to a lack of new ideas, or a dearth of competition, or a value of consistency over innovation, or raw material constraints, fashion trends, government regulation, secretive cabals, unicorns, witches casting magic spells, or (!) lack of selection pressure (i.e. competition) or a thousand other hypothetical reasons. In any case, another reasonable explanation might be that it was simply
better than previous designs (thereby gaining acceptance) and went unchanged because it is good
enough (enabling duration). Furthermore, applying "survival of the fittest", i.e. evolution by natural selection, is quite canny but it actually backfires. Lack of inherited modification is nearly always exclusive to extinct species, with 99% of all species in history now extinct. One-hundred years is, to put it mildly, insufficient to demonstrate ultimate resistance to selection pressure. In any case, further study would be
required before any claims to evidence would be credible.
As for (3), this is probably a difference of terms. I'm sure you're right that tons of work as been devoted to these questions. But a study? I'm sorry, but there has never been a blinded, peer reviewed study on this topic anywhere. In point of fact, there is absolutely no non-subjective material, let alone actual studies, that provides a shred of supporting evidence, even at the most minimal investigatorial standards, in support of using bolsters. There isn't even metaphorical evidentiary support, something the opposing proposition can at least claim. As for dogma, when you have any idea "X" being followed without evidence and being aggressively defended in spite of the absence of objective supportive material, it is accurate to characterize it, as I did above, as dogmatic. "My" proposal is based on hunches, the experience of 18 months and 2 dozen or so whips, half of which have been gutted and autopsied, and engineering, quality control and 14 years of martial arts. I have to admit it's actually more likely than not that I'm wrong, but either way, evidence has to be the determining factor.
Finally (4) you assert that all-braided belly construction has "...no discernible advantage one way or the other in the majority of whip types." This could be true, and while again "only" an informed opinion, not evidence, it does provide a testable condition that could produce factual, rigorous and repeatable results ( i.e. evidence.) It could be the path to a meaningful comparitive study.
A bit more....
You suggest that bolsters fill "...very tiny gaps..." that result from braiding that is not completely solid and smooth and that, in so doing, the bolster makes the thong "...completely and consistently dense and solid..."; I suggest that this bold conclusion is, in fact, in logical opposition to more probable outcomes. First, only if the bolster is made from the same materials as the braiding, is split (or not) just like the strands, and is oiled and stretched identically as the strands, might it function as you suggest during use. This is because the ultimate density of the bolster, even if, say, it is made of kangaroo hide in a kangaroo whip, is highly unlikely to match the density of the rest of whip OR be itself internally consistent. So the whip has materials of at least 2 different densities (more likely a large range of densities depending on how "compressed" a given area of bolster is) making it more likely softer, not firmer, than rigorously applied braided bellies. Moreover, mushed bolster
might fill those gaps but could very well act like dirty motor oil or arterial plaque that slows performance, compromise consistency, and invites long-term ambiguation of joint integrity within strand links.
I'm coming at this with a hypothesis that bolsters are an economical and expeditious means to absorb errors in construction and otherwise augment appearance, but the only improvement they provide is esthetic (i.e. visual and tactile) - they disguise problems rather then correcting them, artificially boost girth for esthetic reasons, and compromise performance and durability. Worse still, it's inactive, dead material that saps the energy transfer ability of the plaiting.
Of course, now I have to find evidence and
prove it, or more likely just prove myself wrong, either outcome being equally valuable and worthwhile. Meanwhile, I'm working on an Indy right now that uses bolsters following all the specific advice I've been given here VERY closely...this is great stuff. I'll be back in another couple dozen whips or so, probably with egg on my face, but that's life.
