[pianotech] stuck keys after one hour of playing

RE: [pianotech] stuck keys after one hour of playingNo oils will work if it is a plating issue. That was my first attempt to solve <G> the problem.
Plating expands and grabs the felt.

  I have run across that...not often, seemed to me it was Korean makes...but I think it had to do with the centerpin plating.   You could work the flange back and forth a number of times and it would seize up...I'd just protek/goose and see what happens.   Certainly repinning will fix it but pretty expensive...

  Howdy,



  I just got a call from a fellow who has an almost 10 year old Wurlitzer grand (I think it was made by Young Chang--correct me if I'm wrong.).  He said he's been having some trouble with keys starting to stick <after> he's been playing for a while--like an hour--and then they just won't go.  We've made an appointment for me to come out and have a look.  I will check the action centers & keys for friction levels, of course, but this seems sort of unusual--well, I've never been witness to such behaviour, anyway.  Has anyone else experienced such symptoms?



  Thanks,
