i have a yamaha trumpet. i got it brand new and it is 3 years old. I recently did drop it and i have a tiny dent on the last turn to the bell. after that they started sticking . There are no dents on the valves or casing surrounding them. i brought them to Quinlan and fabish and showed them the sticking they replaced the valves spring padding and the such. They also did an ultrasound cleaning i think it is called . they are still sticking. Please any think that you can suggest i showed my band teacher who suggested going to Quinlan and fabish. Then my trumpet teacher who said i need to oil more after the cleaning please help
Check that you are not putting sideways pressure on your valves when you press them downwards. Even on a good horn this sideways pressure can cause friction between the piston and the valve casing. Avoid this by arching your fingers a little, depressing with your finger's tips, and avoid the pinkie finger ring entirely. Tying your pinkie up in that only restricts your 3rd. finger's freedom of straight downward movement. Over- lubricating the valves can be as bad as too little oil. Do the whole warm bath treatment that you would normally do to clean it, add 3 drops to each valve, work horn for a few minutes, wipe valves with very old (washed heaps of times) t-shirt: then finally 2 drops again. If this doesn't work, get a trumpet specialist teacher to take it home for this treatment.(You might not be bathing it right). Failing that, check my web site's repair section. Good Luck!
