Rolling Tool Table from Stacked Tires

Rolling Tool Table from Stacked Tires

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.

Ultra High Performance Double Pendulum

Ultra High Performance Double Pendulum

We covered Flickr user yamamo2’s (and his father’s) first high-performance double pendulum build back in 2009. The first version would swing for about 10 minutes, without added energy, after being started. The latest version swings for fully twice that, as the embedded video—all twenty-two minutes of it—thoroughly demonstrates. I haven’t seen any info about the design changes required to achieve this level of performance, unfortunately.
