"GoodYear" rubberized fabric, etc.
Hello, Ed and All,
I have a small sample of "GoodYear" (as they called it then) No. 10 rubberized fabric and have given it a fairly close examination. On the sample I have, two layers of thin lightweight fabric (linen, cotton or even silk, on special order, as was used by Tom Baldwin on his Red Devil Biplanes) sandwiched a layer of a rubber compound which, in a semi-liquid state, was forced under pressure into the weave. The result was a waterproof smooth fabric which was tear resistant and didn't sag, even when wet. These qualities made it No. 10 the covering of choice for many Pioneer Era aeroplane builders.
I haven't been able to locate a sample of GoodYear No.7 but as I understand it, No. 7 was a single layer of fabric impregnated with rubber, and so was lighter in weight but was not as resistant to sagging and water as was No. 10.
Another popular fabric for Pioneer Era aeroplanes was "Naiad" which was not rubberized. "Lumina" was a rubberized and aluminized fabric used on most Wright Model B biplanes.
Ed, are you building the "Sonora"? If so, looking at photos of it I'm fairly certain that the "Sonora" was covered with "GoodYear" No. 10 as opposed to No. 7, since in those photos the covering has a decidedly sturdy look to it.
Best,
cfgray
