Bilge Box 13

First picture of two of how the top plates will fit into place. Two 3/16 inch dowels will be used to align and hold them in proper position when glued. (edit: I used drywall screws and just filled the holes later). Three layers of masking will be applied to areas where the final primer and paint will build up the thickness slightly. The theory is that the box assembly will then fit neatly into place with very little gap, and the mounting holes not thrown off by the final extra thickness.
