Rather warm, humid, dismal. A thunderstorm of some severity to begin the day and rain continuing heavily all day without a break. To Wimbledon along rail path to buy pussies food. Made up a strand* motor to drive the new 14 ins diameter propeller.
*Note: a multi-strand set of long elastic, the strands bound at both ends into loops to hook in and wind up, connected via a simple home-made ratchet mechanism to the propeller, in Fred's wonderful homemade aircraft, made of a balsa framework covered with doped tissue paper, and with a hand-carved propeller.
