In re-reading this post, I realized I had replied in haste and made a mis-leading response.
<<My research tells me that the lowest 1/3 or 1/4 of the bore inside the barrel controls the twelths from E to B, F to C.>>
This part is OK. Obviously I mean the throat register to the A, B, and C at the top of the clarion.
I went on to say:
<<I have had some success opening the bore of the barrel in the lowest 1/4 section of the bore a few thousandths of an inch.
Counter-intuitively, opening this area raised the throat tones and lowered the clarion A, B, C; the corresponding 12ths.>>
I made it sound like this could be done to any old barrel. It cannot.
What I have been doing is boring a berrel to a very tight "Moennig" style reverse-conical bore, then opening the lower end, the small end of the cone, as it were.
This is what I was describing. If the bore of a given barrel is already reamed to something say, 14.7. (assuming an R-13 type bore, not an old B&H or a Selmer CT) additional reaming will just cause more problems.
Sorry if I misled anyone.
