On this day in 1926 two gentlemen started a long-distance chess match by mail. For 50 years Messrs. MaClennan and Grant made only one move per letter. Unfortunately, Grant died before they finished the game. If you're a patient person, you can take chess from scratch by building your own chess set out of nuts and bolts and interesting connectors and fasteners from your workshop. Or you can buy pieces at the hardware store. One-inch, round-head carriage bolts in a hex nut make great pawns. Upside-down lag bolts become bishops. Thumb bolts and nuts make interesting knights. Castellated nuts on big bolts make castles. Threaded eyebolts become the queens, and wing nuts, the kings. Paint them, and let the games begin. And that's the On The House tip for today.
