Before I got to this, an electrician had removed all the keys without
some sort of sequence marking, so I ended up with a carrir bag of them.
I assumed out there, via google bunging in
roland keyboard keys, CF1,EB2,CF, D, A ,G , C ,23
someone would have put out there the sequence required to lay up a
Roland keyboard moulded with those cryptic alphanumerics, but apparently
not. Any pics I've found is ambiguous as the degree of left and right
throws on the white keys, let alone the unseen pivot slot widths that vary.
C D E F G A B C is not very helpful

Looking at an old Casio keyboard, for white keys the direction of throws
at the leading edge is, per octave
CDEFGAB
right,double equal,left,right, double biased R, double biased L, L

The Roland moulding number sequence of each octave is
EB2,CF1,D,EB2,CF1,G,A,EB2
top C is CF and black notes 23

Lay out the white keys , just laying on the top, mark the pivots that
take the black keys, remove the white keys, set all the black keys in ,
then all the white keys, finally set the springs on with a hook. holding
the fixed static end with a finger to avoid the spring flying off
