lol, i just left a tip, but fees were just as much, Great vid! It is really helping. I have the issue with a Tuba, a Wessex, it is a really good nick, but was a tad clancli. I did remove the rotor, cleaned, and placed back. Now is nice and sweet, just need to buy some more bumpers. Thanks, dont stop! try to make a vid with a tuba if you can.
Thank you for the tip. I hope to do a series on a sousaphone on Fridays as soon as I am done with a saxophone repad. I will try to do other tuba videos as the opportunity arises.
I just bought a barely used Holton H-279 to replace my old F.A. Reynolds Contempora. The first thing I did was disassemble the horn for cleaning, but when I began reinstalling the valves, I realized that while there are witness marks on the bearing plates, there are no corresponding marks on the valve casing. I'm not entirely sure how the bearing plates should be clocked so that the marks on the valves line up for trimming the stops. Is there a method for aligning the rotors by eye, because while the horn still plays decently, I can hear a difference in tone. It sounds like when a lever is not quite depressed fully. Any help would be appreciated.
Check again for the marks on the casings. They may just be very faint. If there is no mark, line up the rotor bearing so that the mark is pointing to the levers and align the valves that way. If that does not work, you can pull out the valve slides and look down them. This is a little difficult to do on 1, 3, and 4. You can also use a small dowel or something to feel through the slide tubes to see when the rotor is aligned. I hope this helps, Art
@@TheBrassandWoodwindShop Thank you for the reply. Looking down the slides was tough simply because it was hard to see. The dowel worked pretty well though. Since I've gotten everything reassembled, I used the camera on my phone to see down the tubes. It's very close but still not perfect, and I'm still not sure the bearing plate on the trigger is clocked correctly. Sounds so much better though. I wonder why no manufacturers make a keyed bearing plate that can fit only one direction. I almost think my old horn from high school did. It was a rebuilt Holton H-179, but it had some custom Lawson components, including the lead pipe and valves. Loved that horn. Thanks again for your help.

Very good info!
teacher as always good
Great video! How do you adjust it if the french horn has all mechanical linkages?
How do you align if there are no witness marks on rotor and rotor plate?
