"A repair shop" immediately comes to mind. As has been kicked around many, many times here, replacing them should be done --at least the first time-- by a qualified repairman.

Gotta love an engineer. That's a good comment.... remember that I said that I are one, too!

My compliments to your having the presence of mind to get something to get you through a gig!

Hoover vacuum cleaner belts work well, too. and they're super cheap. I like to use cork for the return bumper though, so it doesn't bounce.

The hot ticket for these is o-ring material. It is available in so many sizes (including metric) that a perfect match is likely. You can get it at most auto parts stores or industrial gasket supply sources. Take one of your existing bumpers to get just the right size. A lifetime supply for your horn will probably set you back less than $5.00.

i had a similar problem, if they fall off easy, but you go to Baltimore Brass, and Fedderly will spiff you right up. But of course if you dont live in B-more, then i guess it would be smart to try somewhere else

Go to http://www.mcmaster.com/ and look for Amber Polyurethane Rod 1/4" Diameter, 6" Length part numbers 8784K821 (40A Durometer hardness) or 8784K822 (60A Durometer hardness). Some people like the harder one for the stop and the softer for the return.

That's really odd. I've been playing various horns... mostly rotary tubas since 1956 and I've NEVER had a bumper just 'fall out'.

You obviously don't "play" hard enough...

.... now that I think about it, I DO recall one time back in 1967... at a TubaChristmas... there must've been a half dozen or so rotor bumpers rolling around on the floor
