Diagram for Marking the Dial and Making the Style
This will complete one-half of the dial. The other half is done in the same manner, leaving a space between the line AH and its corresponding line for the other side of the dial. This space should be equal to the thickness of the upright shadow-casting piece, or style. The style has its base equal in length to the line AH, and its angle, S, equal to the latitude, or the angle CAB. It is mounted in the space with the high end at 12 o’clock. It may be fastened to the dial with screws passing through the base. Mount the dial horizontally on a suitable pedestal. The style should be exactly north and south, with 12 o’clock toward the north. The dial will be fast or slow over clock time. This is corrected by consulting an almanac and setting the clock accordingly from the dial. A correction plate may thus be made and mounted on the pedestal.—F. B. Walters, Baltimore, Md.
Homemade Roadster with Motorcycle Engine
By mounting a 5-hp. motorcycle engine on a frame built of 2 by 4-in. stuff, and rigging the outfit on running gear made of gas-pipe axles, old buggy springs, and motorcycle wheels, I made the light roadster shown in the photograph, at small cost. It develops 30 miles an hour easily, carrying only the driver, and has carried five persons. The frame is suspended from the springs, with an underslung effect, on the front axle. The power is transmitted by a friction drive, consisting of a fiber contact pulley, obtained from an old commercial car, and a disk used as a cutter on a plow.
