Overall cost: $$. Lumber varies by region, species, and season, so we give a band rather than a figure.
Tools: Drill / Driver, Pocket Hole Jig. Materials: Pine or fir, 2x4, 8 ft
Attach legs to the top boards with 2-1/2" screws, framing nails, or pocket holes driven from the underside (1-1/2" pocket hole setting, 2-1/2" pocket screws). Build two identical leg sets this way.
Tools: Drill / Driver
Attach the 26" support boards to the two leg sets to form the cooler frame, using screws, angled nails, or pocket holes (1-1/2" setting, 2-1/2" pocket screws). Position the bottom boards at a height that will let the actual cooler rest on supports tied into these boards — see the next step.
Tools: Drill / Driver. Materials: Pine or fir, 2x4, 8 ft
Attach the bottom support slats to the frame, setting their height so the cooler's top — including whatever decking material covers it — sits flush with the top of the frame. This is worth test-fitting your actual cooler before committing; you may prefer to leave these supports for a later step once you can confirm the fit exactly.
Tools: Brad Nailer. Materials: Pallet boards, Finish nails, short
Attach pallet boards (or other reclaimed boards) to the outside faces of the frame with nails and glue — keep nails no longer than 1-1/2" so they don't punch through the often-thinner pallet stock.
Tools: Brad Nailer, Miter Saw.
Build a 2x4 frame around the cooler's own lid. Attach pallet boards to one face of the frame with glue and smaller nails (under 1-1/2"). Glue the cooler's plastic lid to the wood frame with a polyurethane construction adhesive rated for plastic-to-wood bonding — standard wood glue won't hold this joint.
Tools: Drill / Driver. Materials: Hinges, Towel hook or bottle opener
Set the finished lid assembly on top of the cooler and attach with the hinges. Add a towel hook or bottle opener to the outside if you'd like the extra function.
