No problem, kind of a Sub-D aproach to it.

Hi Grendel
The Canvas is actually layed out over the wing and sewn together at trailing etch and wingtip. then
painted with something called "dope". That makes the canvas shrink and the ribs stick out.
Hope that helps.

I thought that last one from grendel pretty much nailed it!

Indeed. I believe that Grendel's suggestion does it. Well done, gang ! And thanks a lot. Your help is much appreciated.

Andy - That makes sense..you would want some sort of waterproofing to prevent the wings from retaining water and some way of pulling it taut over the frame.

Grendel - that dope or, taughtning dope, as they called it did all that. Some celluloses based compound.
Awfully smelling stuff. That why the name.
