Well, quite. One can both hear and feel the drill reaching the bore. Nevertheless it was something I was warned about, and was checked up on. Now I'm wondering about the acoustic effect of all those "dimples" that do occur in various makes of pipes (historical and otherwise) on what I believe is supposed to be a smooth shiny bore. (Not to mention all the "agricultural" standard bores that are about - this a phrase which makers fettlers sometimes use!) My ivory chanter is jointed near the low E and when I got it, squeaked on that key at the least provocation. Adrian had a look at it and suggested there was possible unevenness in the jointing. We had a bit of a go at sorting it and the matter improved (so did my playing, which probably helped too). The point being that I'm wondering whether the uneveness caused by drill marks in the bore would be sufficient in some cases to upset or affect the standing waves and therefore tuning / tone / stability / reed / whatever. Since that's physics, which frightens me rigid due to some very poor teaching in my yoof, I'm going to tiptoe away now and let the heavy duty theorists get to work on the suggestion.
