Spotted in the MAKE Flickr pool, this clever idea for recycling dead tires (or storing new ones) from Pittsburgh’s Joe Katrincik. It’s two smaller plywood circles for the base, a larger one for the top, 6 castors, 6 screw eyes / eyebolts, and 3 ratcheting tie-down straps. I bet if one were to counter-bore the top holes, a bit, and used T-nuts instead of hex nuts to secure the top eye bolts, one could avoid having the nuts sticking up above the work surface. If one thought it mattered.
