Yeah, I'm thinking I need to run something through that casing again tonight, but we really only get a half-hour of prep before downbeat, and because the horn is set up with the mic, I just leave it there. I think when I get home, I'm going to try to flood the leadpipe to main slide with vinegar, and see what that does in the way of helping.2nd tenor wrote: ↑Thu Oct 27, 2022 11:28 am On sticking valves the old Besson three valve Eb that I have had intermittent sticking valves, that sticking has been cured with: repeated cleaning of the (inside of) the valve casings, repeated cleaning of the valves, clearing of (tiny amounts of) muck and burrs from the casing keyways, plenty of oil, and plenty of use (playing). Your valves springs are likely to already be OK but a fresh set won’t be expensive, ’always’ oil your valves before a performance; sticking valves are almost always and an avoidable impediment.
In terms of oil, I remember seeing something about basically going "overboard" with lamp oil, in a way that it coats the inner tubing of the horn to help protect it. @bloke , do you know what I'm talking about? Because I'm not sure I have it right.
Currently using classic Hetman, but hoping to ship the valves off after this run to a guy for a full rebuild. There's some pitting/plating wear on the valves, and the slides have some alignment issues, so I'm going to just bite the bullet and get them fixed for a fraction of what a new 3/4 BBb would cost me.
