Re: Okay customizers, what would you do with this?

This will be an interesting experiment and might answer some old questions about bore size through tubing.

If you put that .547 attachment on a .547 horn, it might play well into the upper range where most people don't use valves. If so you'd be better off with G or some other choice than F.

curious about where lime comes from

The ultrasonic thread talked a little bit about various deposits. We all know some of those deposits seem to be lime. They look like it, they dissolve in acid, I haven't questioned it. But where would that come from? Condensation seems unlikely, and while trombonists do sometimes use tap water, thos...

Bruce,
I don't think the sound wave itself does anything.

I think all of the cleaning occurs because the sound wave creates tiny bubbles which burst against the object, washing it with the solvent or soap.
