As I start to undertake this process I have been thinking about this and how it might be done easily. My thought was to first make a template out of masonite once the board is removed. To do this lay a sheet of masonite over the top of the rim. Trace a line around the outside of the case. Since the case has uniform thickness, you will need to retrace the line spaced at the thickness of the case inside the original scribed line. Take off an extra 1/8 " which will allow for 1/16" clearance all around. Cut out the masonite form which can now be used as a template for all similar models. Use the form to cut the panel to the right shape and size. Make the ribs and set them into the existing notches in the rim. Lay the panel over the ribs and mark on the board the placement from underneath. Then glue them on. Comments?
