Are you going to change the way the bell section locks onto the body?

This build should be very interesting. Joe's ideas on bore size make so much sense. Not to mention, Joe is a master at what he does. Thanks for sharing this, can't wait to see how it turns out!

Very interesting - thank you for sharing this build with us.

(I've had a secret theory that the cimbasso needs a smaller bore valve section than what is customarily available. Hopefully, your impetus to tackle this will give me the courage to follow suit.... :tuba: )

I have a question about the mouthpipe (or should I wait till you get to that point?)

Fascinating thread - - - -

What will the length of the mouthpipe be, approximately, and will it be detachable, or fixed? Will it be "tuba-like", or will it have some sort of trombone venturi feature?

I previously built (now scrapped, valve set used elsewhere) a cimbasso utilizing a .689 King piston valve set, and I suspect (although I'm not really 100% certain) what I didn't like about it (harder to fill than an E flat tuba of a similar size) was due to the mouthpipe design.

So, where does the mouthpipe taper end, and the cylindrical tubing begin (at the nickel-silver tubing)?

(Forgive me for such obvious questions, but believe it or not, I've never held one in my hands.... :oops: )

Are you going to add hand rests? (My biggest complaint about the Chinese cimbasso.)

Thanks for that info - the tapered part on the one I built pictured above was VERY short (about 6"), and I think response suffered as a result of it (too much cylindrical tubing, not enough tapered tubing). It felt as though it was nearly impossible for me to fill it with a bright cimbasso-like" sound. I was trying to make it adjustable and removable, which I think was asking for too much... :(

I'm assuming that the bit that bends before the receiver is not removable or adjustable?

It seems to me that rotary valves make the construction much more straight-forward.

Bloke, at the risk of being a pest (and you know I'm not trying to be a smart-@$$ here), you really haven't answered my question.

I am totally aware (since I've read every post in this thread carefully) that your horn is substantially different from the model from whence it springs.

Therefore, you must remember that I am a cimbasso neophyte and have never held a cimbasso of any make in my hands (other than the one I built, and that doesn't count). With that in mind (and with a low-resolution picture of the Rudy cimbasso to use as an example), after reading your answer, I can only deduce that the Rudy does have a detachable mouthpipe, while yours does not.

Is this correct?

Why are you going with 2 floor pegs?
Do you like the stability? (no side to side wiggle)

For me, it's not a project unless I have to go to Home Depot 3 times. I suspect you have to have at least 3 deliveries to have it be a project.

Hello, is this the interwebs??

We've run out of pictures of beer maidens.

You can send some right away??

Thank you!!

BORING !!! and REALLY time consuming... and I have one more to make ...and two more beyond those, except without the tensioning feature.
(At least, it WORKS. :( )

STUPID little stuff like this is WHY most of my projects are STILL sitting in cardboard boxes in the attic, and why I tell other people, "No...I don't know how to make that."
I've seen Lee Stofer's attic. You both likely have the same problem, not enough time for your own stuff because your taking care of everyone else's stuff.

Just curieus
-assuming that your sound concept of cimbasso is to sound more or less like a contra-bass valved trombone; how closely does your lead pipe proportionally resemble that of a tenor trombone?

If the double pegs don’t pan out, you could always consider a bassoon thigh rest. I once played a friends cimbasso made this way and it was very practical.

Nice work.
