Time to finish my double bell Tuba!

[Binawhile]

This thread could probably live in the "Wanting To Buy" forum but I'm posting here to share the project and get some advice.

This 1925 Buescher has been through a few mods. It came to me as a small bore 3v front action. I added a 4th valve and played it a lot. When an unknown .687" 3v cluster popped up, I ripped it apart and started rough fitting what was meant to be a 4 piston/1 rotor setup. I had just finished cobbling together random tubing lengths and bits from the parts bin to get it playing when a couple bass trombone/tuba/cimbasso doubling gigs fell in my lap. As a proud double bell euphonium owner/player, I couldn't resist. I added the Salvationist Publishing baritone bell I had saved for a cimbasso project to the rotor and, voi-la! A double bell tuba!

I played it a few times, then shelved it, waiting for parts to finish it properly, then kind of forgot about it... 'till now! For a start, I need long lengths of .687" tubing and some matching outer slide sections. My supplier went under which is part of the reason I paused. I'd like some advice for a new mouthpipe also. I'm hoping to deepen the tone and open up the low end. I'll probably upsize the receiver as well which means I'll be needing some mouthpiece recommendations. Finally, I might be in the market for one of the one-piece Buescher recording bells... But realize that's a stretch.

Any advice, sources, and parts would be appreciated. Thanks in advance! More pictures and work gets done.

That sounds very interesting! It looks like you need to adjust the setting on your google drive link. It says that I need access to see it.

Does this work?

I have a Buescher recording bell, but it's a two-piece. Long and narrow. Buescher made some interesting instruments.

This one looks very cool. Awesome project. Has it been shortened to CC?

Interesting! I wonder if the measurements would jive. Can you send measurements (bow connection, bell tennon, and flare) and pics to jfbasr AT gmail , please?

I haven't cut it at all from it's original Eb length.
