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
That is really helpful advice, thank you very much
You should get a serpent or ophicleide. The air leak is the feature lol
At least the ophiclide has consistency
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.
Thanks! That really helped!
Very useful! Thank you much!
Thank you!
Excellent!

You have my sympathies.
its crazy how much weight hes lost. Edit : ( oh wow i never expected to get this many likes )
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.
Dude so true
I just performed at the meyerson ad Dallas, Texas
Epic
me too
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
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?
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!
Rest in Peace, to the usefulness of that horn in concert. 😢
What song did he play first
how do I know if my valves are leaking if a have rotary valves
OK has any manufacturer ever explored building a valve with rings somewhat similar to internal combustion engines.
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.
Would you please be a host on Top Gear!
This actually doesn't sound that bad honestly. The muffled tone could work in interesting contexts
Could you make a how it’s made for flute I want to laugh even more
Do a trombone battle with trombone tombo
I know it's not related in the slightest, but I implore you. Make an honest trombone recommendation video please!!
Thicker valve oil.
You'd need to use something thicker than honey to plug all these leaks.
The wonderful world of brass.
