Gear Up
Or gear down-for the science fair or for any number of hobby projects. This hard-to-find set of (3) combination spur/beveled gears-for when you want gears set either straight or at 90° to one another-also has one small spur gear, plus three bushings. All in red, green, or blue plastic (we'll pick). The combo-beveled gears are 1-5/8", 1-1/4" and 27/32" dia with 3/16" bores to accept the bushings, which are 3/16" OD, 3/32" ID. The straight gear is 17/32" dia with a 1/16" half-bore. All are 24 pitch.

Fun On The Fridge
Even as you read this, our office refrigerator is playing all by itself. Yours could, too, if you had this extremely cool set of automatic working-gear fridge magnets. Very instructive for budding engineers, just plain fun to watch, and, we assume, amusing for the ice box itself. You'll get (20) 3/8" thick plastic gears in assorted neon colors, all of which interlock in various patterns and turn all by themselves, driven by the 5" dia x 2" thick motorized gear/picture frame that runs on a couple of "AA"s that you provide. Gears include (7) at 4-5/8" dia and 3-1/2" dia and (6) at 2-1/2" dia. Buncha bright stickers included at no extra cost.
