Nice. That looks fun as a day on the lake in spring.

This looks really rad. Very nice creative work. Have fun with it. If you build a case for it, you will need a pickup to haul it around.

Nice design, but there are potentials not exploited.

The detachable bell should be mounted to spin in either direction and a various speeds by means of a pedal controlled electric motor. With the inner bell flared covered by multicoloured glass mosaic like the sphere of a disco ball and a light source mounted on top of the 3rd slide crook you would come close. Ideally the 3rd slide should be trigger activated. Not so much for pitch purposes. Rather as a visual attention grabber. Could be motor activated via another pedal. Or activation could randomized by means of a computer.

This was a fun project to help build, Ian had it all worked out how he wanted to cut the horn, Take a closer look at the conn goose neck that we fitted with the org. king reciever and the org. king marching lead pipe brace. and look at the Bell Brace made from the org. bell brace but cut apart and longer brass square rod between... Thank you Ian for letting me
help with cool Horn It really was fun to built...

Wonderful that you are cheering up us dull guys, Harv!

Please allow for one tech question though: Is that lever arm under the neck to be used with the octave key?

Klaus

Nice Horn! This project resembles another horn that Harv and I made for Sergio Carolino.

Harv and I have done a lot of projects together and I can only say good things about him. After having approached many famous European instrument makers with ideas for instruments, none of them were interested in making them because of the countless risks and challenges that were involved. Harv, however, was the only person who willingly accepted such challenges.

Harv's Pennsylvania pedigree can stand up to the Liberty Bell and fried scrapple. Furthermore, his work ethic is comparable to the Amish! Harv can do anything! Keep up the good work!

Nice jazzophone!

My Dog (Porter) The Boxer add alot of Happiness To ever project ..He always in right in the miiddle of all the work all the time.

Nice work fellas!

I am soooooo!!! Proud of that Horn Its A KICK !!!

If anyone wants one ... Ian's Takes The orders... Thanks Harv.

A "sexyphone!" "I'd buy that for a thaler!"

If I keep seeing these, I'm gonna have to make one; I've my eye on a Couesnon carcass; the extra ferules negate the need to cut the top bow.

Nice work, Harv; happenin' horn!

I also agree with Krause's suggestion about the third slide. However, it would only be practical if it slid a very long way. For this reason, I think
it should be switched around, on the next horn probably, so that the third slide goes down and the forth slide takes its place (approximately) and
can be used for compensating and also alternate fingerings with the slice almost a foot and everything switched around a half step for showmanship.
(It would be hard to figure out though) This might facilitate easier draining too.

I had though about having it come apart, but wanted to remain as close to a bari sax as possible - so only the neck is removable.
Yes, the third slide is a bit long and in the way when reading music. Future designs will definitely have a better position for the slides.
Oren's tuba was a top action and those seem to be aplenty.

That Yamaha hex screw together ferrule wouldn't be practical in my opinion. It would also be expensive and probably the wrong size for that area. What would make more sense is a custom made part that would but the two pieces together and a nut that would let you screw the two pieces together. Think kind of like a trombone hand slide connector without the tapered fit part. This should also let you adjust the angle at which these two pieces connect. Having something like this custom made is going to be a chore though due to the size of the item.

On the other hand you could try a connection at that point like a Sousa bell with a socket. This would be easier to make and more practical.

Do you have video of that?
That sounds A W E S O M E.

There are quite a few given parameters in trombone designs as you have to allow for optimal use of the reach of the human arm.

One of my weirdies in that context actually is tuba relevant:

I have suffered from asthma for many years and in between used to go furious when my pipes cramped. A more productive approach was about training the ability to relax totally at will. As part of that scheme I wanted to improve my bass trombone playing by warming up on tuba. In 1990 the best cut between availability, quality, and the reach of my purse was a 1928 Conn 26K Eb sousaphone (since then things have gone a bit out of control, tubawise).

I tried the sousaphone bits on my bassbone, which of course went flat, but if set so the slide turned right, it still could play in tune with itself. Really a weird, and absolutely useless, experience having the slide and the bell pointing to the right.

Some trombone redesigns are going to backfire like this alto by Glier:
