Rough Sawn Wood Patio Cooler
Making the top sill
The top sill covers the upper nailing frame and also overlaps the sides enough to hide the end grain of the legs, plus some additional overhang. I chose 1-1/4” overhang. [3/4 leg coverage + ½” overhang]
The top sill is constructed out of four rough sawn boards with live edges facing out and the cut edges facing the cooler.
The boards fit snug around the coolers perimeter. I left 1/8” of a space on all sides to avoid conflict with the lid closing. The top sill boards join together with butt ends. To ensure a solid fit I used a Festool Domino XL joiner and then glued and clamped.
