Measuring bore size

Howard Solotroff · 04-08-2006, 10:22 AM

Well, you may consider this an awfully basic question, but I have asked teachers, bandmasters, players, and I can't get a definitive answer.
My question is: where on a trumpet/cornet/flugel do you measure the bore?
I have a number of instruments that I would like to define this way.
Thanks to one and all

Bore size is 'normally' measured at the inside of the second valve crook tubing with a dial or digital caliper, ( if you can read a Vernier Caliper, your eyes are much better than mine ). Some makers have advertised their bore size as being measured at a different point in the tubing. An example of this is the old King,'Dual Bore' trumpets that were measured at two points in relation to the through bore of the valves.

This confirms what a "majority" has said, even tho' there have been other opinions. I'll do some measuring at this point. Thanks for the rapid response.
