Orienting the Blanks
Place the keyboard blank on top of the keyframe. The keyframe is 1/4" [6.35mm] wider than the keyboard, so center the keyboard on the keyframe so
that there is 1/8" [3.17mm] of keyframe showing on each end.
Align the vertical line on the sides of the keyframe with the vertical line on the sides of the keyboard blank.
Make certain that the lines are aligned on both ends of the keyboard. The keyboard blank should now be sitting square
on top of the keyframe. Check the overhang at the front edge of the keyboard blank. It should be the same for the entire
length of the keyboard.
When you’re satisfied that the orientation is perfect, shoot a couple of brads through the keyboard blank into the balance rail thereby connecting
and immobilizing the blanks together.
Please Note - In the photograph the arcade strip has not been glued on yet. This does not effect the measurements in any way.
When the arcades strip is glued on it will simply make the keyboard longer at its front end, and have no effect on line PQ.
