Splitting Duo Gravis Levers

Post by trombinstharry »

Hey all, does anybody know where I can go to split the levers on an old Duo Gravis? Is this something any local repair should could do? I'm in the central Florida area, so preferably near here, but I'm open to going a little distance to do this.

Oberloh In Seattle has done some. You could also talk to BAC in Kansas City, Missouri, or Noah Gladstone at Brass Ark. it isn’t rocket science but you need to find a technician that is comfortable with the task. Some are. Some aren’t.

Here is a photo of a split trigger conversion done by Oberloh in Seattle on a Reynolds bass I used to own. His work is excellent. I also have a former student who is letting his SS Duo Gravis [with split triggers] go due to health issues if you might have any interest.

Oh nice! Did Oberloh add that brace too? Whenever I see a Reynolds Contempora I worry about how securely attached the bell is, particularly if you wanted to put a mute in or something. They are nice horns, especially if you get the trigger split and a D Crook made.

Yeah. Oberloh added the brace and did a beautiful job of it, too. Very artistic work ! Attached is another of the setup that shows the "G" lever and adjustable shoe he fabricated. I once owned a Conn 70H that had a Reynolds double trigger unit fitted and it was very sturdy even without the elegant Oberloh brace.

Oh boy that IS nice. I often wish I was more into vintage instruments so I could have one set up like that. My first bass trombone was from the 1990s so it came ready to go, though earlier versions had a single trigger and only came with an Eb crook.

How did the horn play?

The Reynolds is one of the slickest looking horns ever. I love that wrap.

SweeneyBrass in Raleigh, NC is a little closer than the other shops listed, though at least a days drive from Florida. Scott does great custom work.

Hi,

here's a few pictures to give you ideas , I've had these for many years and my memeory is not always the best but I believe this mod was actually done by Charles? McCracken then man who designed the Duo Gravis in the first place.

I think he said he'd wished he'd made the rotors turn in the opposite direction to help with popping.
