a very good day ...
finally nailed the problem of the power pack end pieces. The design has changed a bit --- i wanted to inlay the printed circuit board so it will be (almost) invisible when the batteries are installed. And instead of using 4-40 screws and nuts to hold the printed circuit board to the 1/4" thick end pieces, i made a 1/4" diameter loop that fits into the wood pieces, and the pcb snaps under the loops:
This is the LAST design issue (for this phase) ... on to designing and fabricating the leather case.
Of course this is a very crude implementation -- the CNC router will provide perfect fit and trim pieces that will look worth the price.
