Subj: Re: [kl] Clarinet Bore changing with use - hence BLOW OUT
Date: Sat, 26 Jun 1999 20:20:15 -0400

I have never played a blown out horn. Perhaps, like Harold Wright and
Heinrich Baermann I'm too "insensitive" to have experienced it. I am,
however, a professional machinist who has measured countless clarinet
bores. Like the young pitcher in Bull Durham, "they're all over the
place!" They can be undersize from their specifications by as much as
.003" or oversize by as much as .002". They are virtually always out of
round. Clarinet manufacturers are either really sloppy or wood simply
changes over time. I suspect the latter is the more likely.

You can run a flap hone with 400 grit paper at 1,000 RPM for 60 seconds in
the bore of a clarinet joint and not be able to measure a diameter
increase. [You will, however, make it nice and shiny.] How a cloth swab
could ever enlarge a clarinet bore is beyond me.

I honestly think somebody is full of it.
