[CAUT] Baldwin Accujust

[G Cousins]

Yes, in thought but perhaps only in certain circumstances. I would question the part of continually adding downbearing. Have to mull that one.

Gerry, 
                Thanks for your post. I’m quite aware of the Baldwin Accujust system. Whether the boards started out at zero crown or not is immaterial to my reply to Benjamin. Continually adding downbearing over the life of the piano will force negative crown eventually, no?

Greg,
If memory serves, the Baldwin boards had zero or nearly zero crown. Perhaps some of the old(er) Baldwin gang could clarify. 
The accujust  (A.K.A. accu"snap") pins allowed anyone on the factory line to string and adjust the bearing. Another plus was you didn't have to unstring the piano to work on the board.  The plate and block all came out in one unit. You work on the board repairing whatever then everything went back in place with effciencies of time. The plate bolts (machined) allowed better easier plate location in regads to the board and bridges. 
Engineering-wise it was a pretty well thought system from the manufacturing point of view.
