SEPTEMBER I8TH, 1941 FLIGHT Advertisements. WELL—PLASTICALLY SPEAKING THEY'RE THE SAME! THIS is an occasion when the camera can, and does, lie. The two aircraft tubes look identical. But pick them up and you'll feel a difference—weight. The one on the left is metal—5 ozs. The other is cellulose acetate — little over 3| ozs. And, of equal interest, it took only five minutes to manipulate the plastic tube into its quiggly shape, including belling; metal workers usually wince when they hear this. MORE and more, aircraft designers and production engineers are turning to plastics as a substitute for metal parts. The designer saves weight and loses nothing in efficiency. The engineer saves time and labour — it's surprising, for example, how little it costs to tool up for plastics. MAYBE you'd care to explore their potentialities in your particular sphere ? BX offer technical advice and co-operation and, where substitution for metal is possible, will submit re-designed parts in the most suitable material.
