Egg Beater Made into Winder for Model Aeroplanes
One of the features which take the joy out of flying elastic-driven model aeroplanes is the time taken to wind them up. For 10 cents and very little work a fast winder can be made out of an ordinary geared egg beater. Remove the outer small pinion and the revolving beater attached to it. Then cut the other beater off at A, as shown in the sketch, and the spindle at B. A few turns of tinned wire soldered to the spindle will keep the pinion from sliding off. Another piece of the same wire may be soldered to the two arms, at C, to strengthen them. In use, the hub of the propeller is inserted between the two arms, as indicated and the rubber wound.—Morris G. Miller, New Rochelle, N. Y.
