I have been reading these posts, thinking I could get my head wrapped around a few terms and brands that I am not familiar with. Just so very beginning right now but I am sure much more will amke sense as times flies by while training.

My little sister years ago, used to sit on the john reading a dictionary to learn terminology--AT AGE FOUR!
She is very no- extremely eloquent in speech right now as a grown woman.
Me thinks I'll be on the john with the Piano Atlas.......

Hi Terry,
 
What is this piano that you're working on?  I don't see a metal spider, so I'm thinking it might be that Knabe you mentioned.  
 
BTW, I am going to go look at a Bush & Lane Pompeiian in Michigan next weekend.  It is one of what B&L called their "traditional uprights," which have the most massive plates of all the B&L's, is a full 58", with the same speaking-length scale as my current one but longer backscale in the bass and also longer backscale at the bottom of the long bridge, and bass bridge direct to the board (not cantilevered).  The Pompeiian is also my favorite of the cabinet styles I've seen so far (same as I sent you a picture of last year).  This vintage (1919) should have the Wessel Nickel and Gross action, and maybe I'll be lucky and it has lost-motion compensation.  However, while these models do have curved sounboard rims, they do not have the plate-flange supported pin-block with the upward-extended soundboard, but I'm not sure what extension in that direction does anyway (my current one has the extension, and does have an enchanting lower midrange, but who knows why?).  Any exciting
 developments after next weekend, I'll report further.
 
Regards,
 
Trent Lesher

Or if the original cut-off bar didn't cut enough off! - But I used new wood, so you still win!   ;-)

  List
     I find this kind of thing fun when I can take a beautiful piece of previously engineered something and adapt it to something else saving big time & cash & utilizing something that originally was very expensive to make & end up with a nice result
  A client brought in a 1900 ish Baldwin upright that ended up needing more than it first appeared, including a board. It wasn't worth doing so the decision was made to scrap it. The tech who brought in the job wanted the beams & such for the maple & I'll be able to salvage the spruce in the lam. beams also. 
    The real jewel though was that this piano had a laminated soundboard liner just like Mason or Stwy grands & uprights ( not as thick as a grand ).  I managed to get it off in nearly one piece with crow bars, chisels & an Oklahama speed wrench.
    Now coincidently I'm replacing the board in a 6 ft. 1 inch Mason AA no. 28,246  which has ribs so long a cutoff bar was really a necessity.    
    The old Upright board liner had plenty of stock for this & by fashioning it to fit the corner of the AA I was able to install a straight 28 inch cut off bar that reduced the overall length of 6 ribs as much as 13.5 inches. My longest rib was 50" & one of the  longest I've ever witnessed in any piano. This rib is now about 37.5 inches long. I don't believe its possible to use ribs this long and expect crown support for very long. Although my observations of the  AA's is limited the 13 rib scale has shown the crown has not survived even with tension resonator claims. Hence the few AA boards I've seen  are usually quite flat. The sound of this piano though fair was quite lack luster in its tonal appeal if you know what I mean even though the board was not seriously cracked up
   The Mason AA has a very wide body & hence very long ribs for a 6 ft 1" piano
   The original rib scale was as follows on the left
   For clarity the measurements below are the actual rib speaking length not including the piece in the notches.
   
   1. 30       in inches
   2. 37
   3. 45 --------38  modified length
   4. 50 --------37.5
   5. 46  -------35.5
   6. 40 --------32.5  
   7. 34 --------29.5
   8. 28 --------27
   9. 28
  10. 20
  11.18
  12. 15
  13. 13
  It's easy to see there is far more hopes for the longevity of rib & crown stiffness than the previous scale. this mod also get the bridge more nearly centered over the long ribs which is IMO a good thing.This original bridge also has the  transition bridge with all the usual funky tri-chords. It's receiving a modified trans. bridge with bi-chord replacements.
  I'll let you know how it turns out in a month or so. The action is done & case stripped. The parts are in the finish process waiting for the belly man to get it done so my finish guy(Roy) can have the case & plate.
   Good new year to all
