 HI Boy & Girls 
 
      WOW ,All this talk of unison  cracking made my brain  numb so I thought 
I'd take a different road for fun  to distract you 'all
  I my quest to learn all I can about Balancing  actions , choosing the right 
parts & balance weights and such has led  me  once again happy to be reminded 
that I Love the Steinway company for  providing me yet another  oppurtunity 
of endless proportions & to  make Bank having  fun making the differing 
macinations &  incarnations of the illustrious Steinway actions work properly. It is 
a  challenge & honestly if wern't for them I wouldn't know any thing about 
this  stuff because they have given me endless oppurtunitys  
..............................etc.
So I'm grateful. You disadvantaged European guys probably  don't' get this 
rich opportunity with the German Stwy  engineering. 
    unt I heer dee have  zee  jeegs  & feexteures over daer too so theey make 
zee  actions uniform ...shhhhhhh   New york  Might find  out!
  You gotta watch out for these factory tricksters.   There always coming up 
with a new  action brain storm.
  Seriously though it is what it is & I enjoy making  a living fixing this 
stuff.  It give me creative license
   
     I'm currently working over a  wonderful sounding 1966 Steinway  B with 
the 
  keys -O- lead syndrome.  Interesting case  study.. The high ratio action 
always has it's tell tale  indicators.
     . i.e..  48 mm blow or  longer  & .375 dip, or less  at the pin &  keys 
full of  lead starting at the balance rail
      Installing the new shanks  & flanges side by side with the old ones 
revealed the location of the teflon  enraptured center pin to be roughly 146mm 
above keybed.  145 to 146mm  ....This fairly typical
  However the new parts pin location is almost 2 mm  higher.  The pin sits 
low in the Teflon flange.  Why? dun no   Hmm...
  The hammers were  bored short for a B at 1 3/4 "  or 46 mm. which was 
correct  for the old parts. 
    The wippen pin height was also higher than  the standard 3 1/4 inch by 
more than 2 mm.
  The beginning action ration was 6 to 1. with 16.5  knuckles.  Using 
  17 mms knuckles  with the different pin  placement made the spread  a 
squeak wider 4 7/16ths but still  brought the ratio  down to around 5.7ish  Still 
to  high.   I also chose to reduce the action height by whittling  away the 
action cleats 2 mm to get the center pins & hammer bore into a  more  typical 
range. 
  The capstans fortunately will be able to be moved  forward 2 or 3 mm which 
will bring the ratio down closer to 5.5 to 5.3 which  would be really great.
  At this ratio I can of course remove lead, reduce  inertia , increase 
hammer  bore length, Increase hammer weight a bit  & improve regulation parameters 
to 1/3/4 ish blow & .390 dip,  which is more typical for Many Stwy pianos.
  It was suggested that another fix for this would be to  get a modern stack 
& strat over.& I beleive thsi idea has merit but  wasn't really necessary. Any 
body do this?
  All this change of course allows a pianist to access  the tonal potential  
of a great instrument, in this case, of a really  good original B belly set 
up. It's a lot of fun.
   By the way the Wurzen hammers on this piano were  right where they needed 
to be right out of the box.  Power without  noise & lots of color.  No 
needling.
  It's to good to be true......naaahhhhh! 
  Happy Saturday
   Dale
