Figs. 35 and 36.—Working-drawings of Model Aeroplane Designed and Built by Harry Wells.
This Model has a record of 1620 feet made at the Aero Club of Illinois' Aviation Field at Cicero, Chicago.
Before fastening the separators in position,
The Thrust Bearings for the propellers, and the end plates for connecting the wire stays, must be prepared. [Figure 38] shows a dimensioned detail of the thrust bearings, and [Fig. 37] shows how they are bound to the ends of sticks A with thread. These are cut out of brass, bent into the shape shown, and have a hole pierced through the folded tip for the propeller-shaft to run through, another through one end for the brad to pass through that pins stick A to B, and another through the other end to fasten the end of the wire stays to. The small detail in [Fig. 37] shows the end plates for the wire stays. These are made no longer than is necessary for the connecting holes for the wire-stay ends. Pierce a hole through the center of each plate for the brad to pass through which fastens sticks A to the ends of the separators. The plates are bound to sticks A with thread.
