I need some new rotar stops for a Yamaha 641 BBb tuba. Does anyone know where I could purchase some?
Thanks
Amy

Most any musical instrument repair shop or parts dealer can fix you up with these parts. Yamaha part number H2141020. A set of 8 is probably less than $5. Sections of neoprene O'ring stock is a good alternative.

Did you know an Irishman is featured prominently in the New Testament Easter account? Nick O'Demus!

It IS getting close to St. Patties day! We got out the 'Hungry Five in Ireland' stuff last week. Fun to play! When my wife and I toured Ireland a few years ago we were known as the O'Schultz clan.

You can cut your own to size from the seal of an oil filter of a car. They stand up to heavy oiling, and it's pretty easy to do with a sharp knife. John

Vacuum cleaner belts worked well for me. Just check the diameter against what you have now.

About rotor stops: Osmun Brass (Boston area repair shop) sold me a 5 or 6 inch length of rubber rod. I don't remember how much they charged, but it was not much. I cut my own and installed them. Easy job.
While we are on the subject... I wanted new ones because the rotary valves had gotten awfully noisy. My YBB 641 is an older model, probably 1980s. I tried to diagnose the source of noise and thought maybe the stops had become hard from all the loose oil that got on them. New stops didn't help. I am trying to keep the new ones dry.
Noise seems to come mainly from inside and from the link between the key extensions and the bar that moves forward and back to shift the rotor.
My fix has been to suck light rotor oil into the spindles, top and bottom. Then use some good chassis lube on the extension/bar link. Have to do this fairly often... every couple of months.

I make my rotor stops from wine bottle corks (for about 33 years).
