[pianotech] Lubing Jack Flanges in Uprights

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
