[Spridgets] Seat diaphragm...

[Dave G.]

I now know the answer to my earlier question...
The webbing style diaphragm is too small for the early seat frame... don't 
ask me how I know....

Also, please don't ask me to repeat the magic(?) words I used when I was 
trying to fit the hooks into the seat frame.

Anyhow, can anyone tell me what the large  hole in the diaphragm is/was 
for... and keep it clean <Grin>  It doesn't seem to have any purpose.
