Dang these puzzlers

[A440A@AOL.COM]

Greetings all, 
     I LOVE puzzles........no,  actually I hate them.  No,  I luv'em, but 
then, I hate'em too, when they suddenly hatch in front of me on my own 
workbench.  I mean,  I like to hear of other's puzzles, but I'm trying to 
make a living here, and time i$.  If this will save some others time, good.

New whippens, shanks, hammers, keybushing .  Kept the original action rails 
and their cloth, keypins  and accelerating half rounds.   
   As I finished the first key-level and rough regulation.(2  hours, I was 
not being real precise here),  I noticed that on soft release in the bass,  a 
couple of hammers were dropping slowly when they approached rest position.  
These notes felt ok, at this pre-B/W,S/W,Dn/U, stage of the game, and they 
regulated and repeated well.   
    It LOOKED like knuckles rubbing, or hammer felt touching neighbors, maybe 
even tight key bushings or a problem with the pins, but it wasn't.  It wasn't 
even a pinning problem .    I thought it must be a geometry problem,  maybe 
the knuckle was bigger, and pressed on the jack in a weird way as it fell 
back, etc......  no,  it was not that either. 
   The puzz-notes were in the bass, and they were A 13 and B 21.  The fix 
required some disassembly first.

(gee, now that I look at it,  this seems a lot easier than it did when I 
started taking the action apart.
