  Hello all, 

   

  I'm looking for advice on the best way to lube the jack flanges on a 70s Story & Clark console piano.  Is it necessary to remove the wippens to do this properly?  It's all pretty tight.

   

  This piano has a handful of notes skipping-plays the first few times, then stops playing, key goes up and down but hammer doesn't jump forward. The jack's not resetting.

   

  I believe the likely culprit is the jack flange or maybe even the jack spring.  (The keys appear to work ok-the fronts come up nicely, bushings don't seem too tight, no rubbing against neighbors; the wippen cushions appear ok, the capstans appear well regulated, etc.).  

   

  And because it sat un-serviced and un-played for so long, I'd like to lube all the flanges.  

   

  I have Protek but I don't have any sort of long wand to spray it, carefully, that far back.

   

  Thanks in advance for any assistance, Gary
