- This is a how-to video about removing a valve that is stuck in the casing, without causing damage.
One thing not mentioned in the video is what to do if someone has put vegetable oil on the valves. Here is a link to a video about that: • Wrong Oil Applied to a...
Also, here is a link to the play list on stuck valves:

Thank you this video helped me unstuck the valve of my favorite vintage cornet!
Cool thanks
Thank you for helping me
Thanks for the video !
After a bad experience about it, I would like to add an advice: prior to do anything, check if there's nothing in the valve ports preventing the valve to move. That's particularly true if it's a kid instrument. I already found 2 hair pins and 1 splinter from a splinter blocking valves... first time I did not check, and I wrecked the trumpet :/
I would also recommend to take a wood dowel (or a metal pipe, maybe from the junk pile ?) which fits the casing, so you hit the edge of the valve and preserve from incidents.
What you do? Go to the Grand Canyon, dropped it, traveled down to see if it was fixed?
Would like to know a bit more why they were stuck in the first place, which could help others prevent this from happening. I'd also start with the larger dowel first as I would rather put the pressure on the valve bottom rather than the cap.
In this case, the valves were stuck because of a build-up of lime deposits, but the repair is the same for almost every reason that valves get stuck (except for a foreign object being stuck in the valve).
Almost always, the smaller one works just fine and does no damage if you are careful. It is fine to use the larger size one too.
I am really glad to have seen this and found your channel. I am just starting to try instrument repair, just testing the waters to see if it is something I want to make a career out of. I have a question though: red rot. What causes it, how to stop its progression, what can be done, does anything need to be done, what effect does it have on the life, sound, and playability of an instrument? I guess that that's several questions, but I have a trombone that has some wide swatches of red rot, and I am trying to restore it out to at least preserve its usefulness. Thanks for all of your videos, they have been truly enlightening and inspiring.
Sorry it took me so long to answer your question. Brass is an alloy of copper and zinc. Red rot is caused when the zinc dissolves and leaves the copper. This happens when someone has acidic saliva. Although red rot is not a good thing, it usually does not affect the playability unless it makes a hole which goes all the way through and causes a leak. This is not common, but it does happen.
Thank you! That is a relief.
I love My trumpets, I love this video too!
I hate my trumpet I hate school I hate my life rn I hate my band class I hate my band teacher I hate myself I don’t feel good at all 👍👍👍👍👍😭😭😭
@@voltzeditz6616 Don Worry, it will go away one day.
Could you use a rag to clean the casing? Or would you need a valve brush for that?
I've always thought that it is very risky to tap any valve from the bottom with a dowel or similar. What I've resorted to doing in the past is to use one of the other valves inserted upside down from the bottom and then to tap that (once the finger button and stem have been removed) that way the force on the stuck valve is only being applied on the outside edge of the valve.
I use this method sometimes too. I did not mention it in this video because it can cause damage to the good valve if it is not done correctly. I did not want to go into an explanation about that in this video and I do not want people to try it and cause damage from what they see on one of my videos. I may do another video on this method later.
Thank you for your comment.

My top valve cap is stuck the valves move
I have a plastic Tromba flugelhorn that's been untouched for several years and ALL of the valves are completely stuck. Any suggestions? Thanks in advance!
I used a metal hammer and a drumstick lmao 😂 good thing I didn’t damage anything!
Tried tapping out a stuck valve from the bottom once...turned out that valve did not have a protective bottom cap so I tapped directly through the bottom port.
Hello. Stuck valves because of valve casing dents? How do you get them out?
Here is the link to a video that I did about that. I hope this is helpful.

@@TheBrassandWoodwindShop , thank you. I got the valves out, and the casings back to shape with the casings mandrels. Now I just have to find a new first piston because the dents where so deep that the piston was dented as well.
What if itd really stuck like stuck
Watch this video and see if this is your problem.

If that is not the problem, there may be something stuck inside the trumpet keeping the valves from coming out. There are a few other possibilities too, but try these first.
@@TheBrassandWoodwindShop but mine is a baritone I think I put the wrong oil
I don't even begin to try to tap them out in the middle. If I don't have a dowel that fits tightly in the valve, I make sure at least that it's flush against one side of the valve so that I'm tapping on the rim. I try to move it around every few taps, just to make sure I'm not making it get out of shape.
I want to know how many of you yelled at the video when he called the euphonium a baritone???? Other than that good video :D
