Diagnosing air leaks by submerging in water reminds me of fixing leaky inner tubes on my bicycle as a kid. Good times 😄

And if you're trying to find a water leak in something, you'll get the best results by submerging it in a bucket of air. :P

I am a euphonium player and this helped me very much thank you.

Playing my 20 year old czech budget student model Euphonium, I did not expect my valves to look worse than a instrument from the 1890s

Kudos to his back surgeon! Trent may never admit it (I wouldn't blame him) but he's a visibly different person than he was a few years ago.

You should get a serpent or ophicleide. The air leak is the feature lol

At least the ophiclide has consistency

Rest in Peace, to the usefulness of that horn in concert. 😢

Proper fix= send it away to get full repair. Cheap fix= get out the supaglue and silicone RTV and boogie up the cracks in the slides, get the valves replated and lap them in yourself.

Great job, Trent! On the sleeves, how do they lower the pitch? Are they larger replacements for the originals and have a higher volume of air?

@jkelley012 Жыл бұрын

Hi Wayne; just an educated guess here - it's not the larger volume of air that matters but the length for causing pitch! (Frequency = velocity divided by wavelength; in this case, pitch = the speed of sound divided by the length of your instrument). I'd guess that you're effectively cutting (or removing) the very end of the slide and using the sleeve to reattach it just that liiittle bit further down.

@@jkelley012 You’re right, of course, about length vs. volume. I knew I was phrasing that wrong when I wrote the comment. Long week at work, man… Thanks!

My baritone horn is about 80 years old. I don't play much anymore. I'm not sure if the problem is my hearing (wear hearing aid and hearing has diminished) or if the horn has just wore out.

Thanks! That really helped!

I bought a euphonium from craigslist, and I took a balloon and inflated it to the size of a grapefruit and stuck it in the bell, and pressed the valves individually

OK has any manufacturer ever explored building a valve with rings somewhat similar to internal combustion engines.

@Metal-Possum Жыл бұрын

Are you aware of the friction involved with piston rings? Pistons are a VERY TIGHT fit, with explosive pressures to shift them. If you're going to ease up on the tolerances so the valves are actually useable, then what's the point? A higher viscosity valve oil will buy you more time in the later years of an instrument's usefulness.

@Alex Paulsen You are correct. The payoff would be very small. I need to review the class on diminishing returns. A whole lot of effort for very small returns.
