My horn (Willson EE flat) is at least 10 years old and has a first valve that occasionally catches due to the valve tubing protruding into the casing (the lesson I learned: don't pick up your horn by the valve tubing even if it is the balance point of the horn: it isn't a convenient handle!)
I've had it seen to by a repairer, who added a brace. Lapping is a last resort for me.
The final straw was during a TV news item on a charity gig. After hours of good opperation, the valve jammed during a solo, just as the camera took a tight close-up of my fingers. Witness frantic valve pulling and alternate fingerings. Luckily it was a jazz gig, so I could improvise around the 'available' notes. Several people mentioned to me that they'd seen the item, and were embarrased for me, so I know it didn't go unnoticed!
Thanks for all the info folks: I hope to clean/lap the horn in the next couple of weeks...I'll keep you posted on the results.
