[CAUT] Original SD-10 Key Height

[Bob Hull]

I have tried the 2 9/16 key height  (about 69 - 70 millimeters) and it doesn't work.

Rebuilding the action of an SD 10 and it appears that someone has already been monkeying with this one.  The balance rail pins are almost buried in the mortise.  The key ht. on the old action is 2 3/4" to the underside of the keytop.   Does someone know what the original specs were?   The piano action handbook says 2 9/16" for Baldwin concert grand but I didn't know if the SD10 would be different than a generic older  Baldwin concert grand.  

Also, original specs for hammer blow and dip if you know.  I'll make my adjustments from there.      


Thanks.

Bob
