Completely stuck valve
Hello! I’m a fairly new horn player, last year i joined an orchestra at my university and started playing on a burrowed and frankly horrifying double horn donated by an older member, and recently bought a a single horn of my own second hand.
This horn had been completely unplayed for about a year, so i bought it knowing it needed some maintenance. I’ve gotten the first and third valve working, but the second is genuinely completely stuck. Most guides and tricks I’ve seen talk about inserting some rotor oil and slowly wiggling the mechanism but I can’t get it moving at all. I’ve tried rinsing it (with soap and without) and also grabbing the mechanism itself and twisting but genuinely nothing works.
What should I do? Just keep rinsing, oiling and twisting hoping I get the (probable) deposits gone? Some stronger chemicals? Cleaning alcohol? Benzene? WD-40? I’d really like to avoid going to a repair shop since there isn’t one in my city and those I’ve found elsewhere cost (the equivalent of) $300 for a cleaning, which is 60% of what I bought it for and would total higher than the price of a new one.
