I have a Jupiter double horn. The thumb valve will randomly stick down and not want to come back up. It however only does this when I play a scale or am in the middle of a song, so when I ask the director or an instrument repair person to help, they think I'm crazy and see nothing wrong with it. Also, the first valve is slightly bent sideways towards the second valve. I got it used and it came like this. It is not horrible, but that makes it significantly slower than the other valves and sticks a LOT. All repair shops do is take my money and claim they've fixed it when they have done nothing. It is so frustrating. What should I do? And the oil doesn't help with either of these things, which is even MORE frustrating.
thats easily particularly straightforward for brand spanking new horns, somewhat hand-crafted ones. The valves are nevertheless very tight and there would be steel debris nevertheless interior the tubing/valves from manufacture, it in basic terms desires to be taken to a competent restoration save and wiped clean thoroughly. previously you do this in basic terms attempt putting oil on the lower back and desirable (decrease than valve cap) bearings, and take out each and all the valve slides and positioned some mild oil (Al Cass works constructive) oil into the valve itself. in the event that they nevertheless draw close then take it to be wiped clean. and FYI concert activities on incredibly new horns isn't a competent concept, apart from mechanical subject concerns, you're able to desire to take time to get used to the device and its pitch dispositions. in view that probably is unquestionably no longer your final horn, in basic terms evaluate that next time.
Open up the #4 valve cap and flood the top with valve oil, put the cap back on and turn the instrument over. Put valve oil in the crack where the valve comes out of the bottom of the valve case. This can be hard to see. Put some drops on every moving part of the valve action. I can remember the layout of that valve but I don't think you can shoot oil into the valve. Try all that I said above and see if that helps. Rotate and wiggle the valve between each step.
