[pianotech] stuck keys after one hour of playing

[Joe And Penny Goss]

Hi Barbara,
It can be any centerpin. Prior to your appointment date it saves time if the client will place a small piece of masking tape or part of a bandaid at the back of the keys that are showing the problem. Then you can zero in on those that might work when you arrive. Also you might ask them to play as they would usually do an hour prior to your arrival. Otherwise you will be looking for a center pin in a hay stack. >g<
The cause is usually tight centerpins caused by graphite or too much glue in the felt and no amount of GJ,  Proteck, Vodka what ever will solvent the situation Only repinning will work. Well come to think of it the Vodka might mellow you out.
Look for a browinsh or black on the outside of the flange, and take a close look at the removed pin . Where the felt has rubbed will be a different sheen than the center of the pin.

  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,
