Thats the thing, David!  Nothing on the neighborhood is affecting it! 
Perplexing!  It checks with normal let-off and drop, but then won't fall 
back into place.  Springs are not real strong, but firm.

Look between everything.  Jack center pin sticking out?  Anything else 
between hammers, shanks, wippens interfering?

Hi Cauter's. 

I always have a new one for you. 

I'm regulating (bench style, right now) a '32 Steinway L that I rebuilt 3 
years ago with new hammers/shanks/flanges, but old wips.  All went fine 
until I took off the stack to raise the sharp height a bit throughout, I 
figured that quicker and easier. Everything worked before I took off the 
stack. 


Anyway, now the A-3 is hanging up on return.  It worked before.  I checked 
the action centers, repinned the wip flange as it was pretty tight, but 
nothing happened. Put everything back.  All works, except this one.  I 
checked the hammer "swing test";  all good with 7 swings.  all other 
action centers good. The key is free and easy, polished the capstan, lubed 
the wip cushion, brushed and tefloned the knuckle...you know, all the 
right stuff.  It's still hanging up on return.  What's up with that?  Just 
the one key.  No neighboring keys are interfering. I checked out replacing 
the wip with a new one, and still the same thing! I switched a neighbor 
hammer, but still the same thing. I can't see anything hanging up.  I need 
to have this action ready and back in action Monday morning. 

What's going on? 

Thanks for the input as always. 
Paul
