| It's a great way to stop leadpipe corrosion, but I don't think it's the best way to oil the valves. The oil enters the bottom part of the valve casing, leaving the top half of the valve dry. I use this technique to oil the rotary valves on a 130 year old cornet I have, because otherwise, the entire valve and string linkage assembly would have to be dismantled every time I oiled them. I also drop oil down each valve slide while working the valve. In a piston valve horn, I'd remove the valves for oiling. Of course to clean them, you must remove the valves anyway. |
