Rework the bell section with three standard valves, or four, don't use the slide, stick a mouthpiece lead pipe where the slide usually goes, and it might come out close to Bb.

If your thing worked for all of them, it would probably be really bad at all of them.

Cheers,

The contra build is nearly done  Pant Good! Amazed and now comes the fun of buffing and then off to final finishing.

Here are some photos of the levers.

Those paddle-ends look absolutely identical to the paddle-ends on my independent converted Holton 169 - really just the same; same-looking metal, same shapes, same curves. I'm told that the conversion work on my trombone was done by Burt Herrick in 1969. Just a coincidence, or is there a connection?

Your valve levers were modified under Bob Weller's ownership. That might help.

I model my valve paddles after the way Larry Minick did his, so that's probably the common connection.

Here is a quick video Brad captured today of our good shop pal, (and tubist extrodinaire) Blake Cooper, demonstrating the BBb contra low register. As you can see, "farty sizzle" is a specialty of this particular instrument  Evil

"farty sizzle"

I will certainly continue to keep my eyes open, but I've yet to find a chart marked with performance instruction.  Evil

Got the instrument back from silver-plating! Final assembly this week and she'll be ready for the front lines  Amazed



I'll post final shots when all the parts are on the horn.

Holy cannoli, that is one gorgeous contra. The slanted braces on the valve tubing look really slick. I look forward to the day that I can make one of my dream horns a reality, just like you've done here.
