I thought since I'll be starting some work on this horn here and there I would move the discussion over to the repair forum, rather than the main TubeNet forum. The photos below are just copied from my post in the other thread. The only thing added is a picture of the polished engraving, just because that's what people do, right? Polish just the engraving?
But last night I got it out and looked at it a bit closer. It looks like the neck that came with it does fit, but when the tension band is tightened all the way, the neck can still move rather freely in the receiver. Is there a way to shorten the tension band to give it a more snug fit when tightened?
It certainly will need at least one bit, simply because the mouthpiece would be too far away from the player if only inserted into the neck. I am bringing home a random bunch of sousaphone bits from work today to see if any will work, then I'll ask around for purchasing one if I find one that works.
Next steps will be to remove the tarnish with Tarn-X and baking soda/water before going after the dents. If one of the bits works, then it shouldn't take much to get this thing playable. There only two loose braces, and I need to replace a cork bumper on the third valve that just disintegrated when I took the valve out (I'll probably replace all three...).
Anywho, thanks for looking and have a great day!
