[pianotech] Lubing Jack Flanges in Uprights

[Ed Sutton]

Be on the lookout for other problems.
A compressed action console will probably need extra lost motion.
Make sure all action centers are moving freely.
And if the keys are not back weighted...let the fun begin...

  Thanks guys-of course.  I'll pick up a syringe today.  I was going nuts trying to dab a drop with a long q-tip.

  Syringe, with needle, lets you put stuff where you want.

    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
