- Old french horns often have loose rotors. There are two ways for the valves to be loose; up and down, or side to side. This video is about how to tighten rotors that are loose up and down. Usually, if a rotor is loose, it is loose both ways. Here is the link to the video about how to fix rotors that are loose side to side.

TIP JAR - paypal.me/bras...
this is why the music shop wants to charge $350-500 to repair worn rotors. not difficult but can be time consuming.
thanks for showing us how!
depending on the worth of the instruments. If you have a 9000.- Hans Hoyer Horn I would consinder not to touch it myself ;-) My Horn was 19.- on ebay so I did it all myself even the soldering,... nothing to loose.
It's just part of the repair, not the whole process. He even said it, it only removes the up and down motion.
What about using two teflon spacers at the bottom? In my case, the rotors came with a small brass ring at the bottom, and i suspect that it was put there to prevent the erosion of the seat and the rotor, like a fuse (something similar to the teflon spacers idea). Teflon spacers should work better (like in the rotors of a fan) and would also fill the eroded gaps.
I have a new tip for loosenig stuck parts. I use lighter fuel and add then, 1sec after the gasoline ultra thin valv oil. The vaporising of the fuel adds some force to the capilary force. So the oil is penetrating the gap very quickly. Do NOT Add heat ;-) if you try this. So some parts come off very fluffy.
I need 2 valve caps cause I have a horn with only one cap but I cannot finde them to buy one ;-( So your videos are so cool bud could you add a shop where to buy spare parts?
I am thinking about doing something similar to that, but it will take a while to be able to do it.
Could you provide information about the chuck you’re using? I’m not finding anything like it in local stores or on Amazon. Thank you!
You can get it from Ferree's Tools.
The information is in the video description below the video.
Could this same method be used on tubas as well?
Yes, it is the same on rotary tuba valves.
