Backracking

Work on the keyboards continues, but I've reached a point where it's time to make a new part -- the back rack which manages the lower keyboard guide pins. I started with a piece of basswood of roughly the right size and shape, then marked it with lines where each of the keys will go. Using the drill press, I drilled holes through each of the lines:




Then with a thin-kerf table saw blade and a special jig to hold the piece, I cut the grooves for the guide pins.



Cutting all those grooves took a while, but then it was ready to screw into the back of the keyframe.



I've still got a ways to go with the keyboards, but now the keyframe is finished.
