Steve,
I agree regarding the weight, I'm either going to use your washer trick or secure it to a heavier base once I get it and put it together.
Jamie,
Thanks, actually it's the larger Chord of the wing, not the span that limits my AeroClub Jig. I have an extended threaded rod on mine which I ordered initially but most of the two seat larger models (most recently the Hansa Brandenburg W.12) can't be fit between the front and back vertical posts. The design of the Vertigo product should solve that problem.
Cheers,
Lance
