DIY Slide Sax, Attempt 4

[@Phylaetra]

I notice that the slides have a fairly loose fit - perhaps adding a velvet ring as a seal would help?

There's a chance that would help a *little*. The tenor trombone with reed mouthpiece(s) on it does not squawk, but it still has very limited range. I would still like a TRUE slide sax.

@@traevoli I was just noticing loose connections, and that cannot help with the physics of the process of changing the acoustical length of the tube(s). The tighter, the better.
