A brass washer was selected to act as the tapping mechanism devised in the second sketch made on 2014-08-31 (Su). Size and shape of the tapping mechanism were estimated with the idea that the shape must have enough room for a #4 (0.11", ~7/64", 2.8mm) screw to pass through and should be as asymmetrical along one axis as possible to promote bouncing when it moves. The dimensions were estimated by marking a hole location on a sticker centered on the washer. The nylon sleeve was held next to the washer and sticker while the shape was sketch with permanent marker. The shape will likely be modified and shrunk after it has been cut out.
