Please watch the video on the blog forconstruction tips.
Notice that the wires go through the feet andfloor. You want to make sure these holes all line up with the cam followers belowthe floor. The wires should be straight upfrom the cams.
Leave the coat hanger wires long until you have the piano made. Then use the keyboard height to set the position of the arms touchingthe keys while the cam is at it’s low point. Onceyou have that set cut and bend the wire throughthe wrist hole.
Notice that the floor is glued between theouter walls.
