Hi all,
Does anyone know on a greenhoe (or similar instrument with large rotary valves) where the tubing is .562 vs .594 (or whatever size it is)?

On which horn? Usually the bore is consistent through the slide, and into the valve tubing, which is usually overbored. The trombone is a cylindrical bore instrument, so it only really expands in areas like the goose neck, tuning slide, and bell flare.

Sorry forgot to mention. A bass trombone with tis. Are the tuning slides for the valves normally .594?
