Glue and bind a small wooden cross brace to the frame, 12 inches from the rear end. The brace should be made 3/16 of an inch wide and 3/32 of an inch thick.
The elevating blocks are 3/4 of an inch long, 3/16 of an inch thick, 3/8 of an inch high at the rear and 1/2 inch high at the front. They should be fastened to the machine by gluing and binding six inches back from the tip. The highest part of the blocks should be towards the front of the machine as shown in the illustration. Be careful to see that the frame is lined up perfectly true and then lay it aside until the glue dries.
FIG. 54. The Peerless Racer.
The propeller bearings are made from No. 18 hard sheet aluminum. It is cut into a strip 1/4 of an inch wide and then drilled and bent as shown in the accompanying illustrations. The bearings are screwed on the rear ends of the sticks "A" and "B." It is also a good plan to bind some linen thread around tightly.
Pass the propellers through the bearings and bend the end of the shaft into the shape of a hook, being very careful not to twist the bearings during the operation. A bead should be slipped over the propeller shaft previous to passing it through the bearing so that it comes between the bearing and the propeller and lessens the friction.
Bore a small hole through the frame of the machine 1/2 inch back from the tip, making the hole pass from side to side. Pass a piece of stiff wire through this hole and bend back each end snugly to the frame to form the anchor hooks as illustrated. Bind some thread over the anchor hooks to keep them from twisting.
Bend two small pieces of wire into "S" shaped hooks and slip one over each of the anchor hooks.
