It seems to me it may. I recall reading a post about John H. having a leading edge failure years back.

When you sheet the leading edge and attach it top and bottom to a flat spar, it forms a "D-tube" and provides a great deal of torsional rigidity (which is provided on Kolbs by the large tube spar). I suspect a sheeted leading edge would be damaged more by a bird strike than fabric... and harder to repair, too. John H's leading edge failure was, I believe, caused by failure of the internal diagonal bracing inside the wing. As soon as you add rigid structure to an aircraft you essentially have a new design, and need to have the ability to do a full structural analysis of the new structure. Adding structure to make one area stronger can move the load paths and actually make the total structure weaker. -Dana At 05:37 AM 12/23/2011, Jimmy Young wrote: > >Would an alum. sheet leading edge offer much in the way of leading edge >protection, say in the event of a bird strike?

Also made a tool to hold the flywheel from 1/4 aluminum. I am trying to attach a photo, but it may not work (never been successful in the past.

I also must wait for delivery and may miss the few remaining flying days before the deep freeze and snow drifts bring it to an end. Has anyone devised a homemade tool to hold the fan? If so I'd sure appreciate knowing how you did it.
