I, too, am a (retired) scientist with many publications, and love to measure stuff and hypothesize.
I am surprised, however, that there is so little dimensional measurement being reported and discussed around both the "blown out" phenomena as well as the formation of cracks. Anyone that has measured a lot of wooden clarinet bores knows that these are rarely round, and in fact, the difference between max and min diameters at any point in the bore is as much as 1% (sometimes more in really dry, old clarinets.
In my limited experience as a woodwind tech, I have oiled (with the doctor's product) the bore and exterior of several 'garage find' clarinets that were extremely dry. In the cases that I measured carefully, all became more round (I found data in my archive for 5 clarinets, but I'm pretty certain I have measured more than that...). So...anecdotally, old dried out clarinets are more oval.
Is it possible that the degree of 'oval-ness' affects the modes of the clarinet. It is pretty well documented that 1% changes of bore diameter in certain regions of a clarinet design can significantly change the tuning, timbre and response of a clarinet, so one might guess (i.e. hypothesize) that an asymmetrical change might, in effect, provide two different transfer functions in the clarinet that are competing for resonance modes at any given note being fingered...i.e. "blown out"
Has anybody collected dimensional data (compared to instrument design parameters) on some number of "blown out" clarinets...
Chris? Omar??
Also, as regards cracking, I have never owned a clarinet that cracked, but have seen quite a few clarinets that cracked in their first few years of being played. I have also seen some huge cracks in clarinets that have been stored badly for years. I can't recall seeing a well-cared-for clarinet older than 5-10 years that developed a spontaneous crack...anybody??
