A good old buddy turned 40 this week, so when the recycle dumpster gave me this fantastic vintage cooler I knew exactly who was meant to have it.
Even when you're so old your bottom rots off, you still have worth, ya know?

Spay-on clear rubber to hold all the old in, and to waterproof the exposed foam.

You can't really see what's going on in this one

 

The bottom part is 3/4" cedar that was leftover from the bookcases still waiting for assembly. The edging is a stainless steel sink trim cut to fit; the sides are spar varnished cedar(?) plywood that I found in the road, screwed into the bottom with stainless screws and siliconed onto the sides.

Aluminum corner pieces from the bit my Mr cut out of the screen door
 to put the cat flap in and more stainless screws.
