: After reading through his site a bit, it seems he has some problems

: support where the "holes" in the honeycomb are. It
: seems a toe would dig in and cause a stress fracture there, and
: then you're in trouble! He seems to think it was just a flaw in
: the cloth. Who knows? I wonder if you could do the same
: construction using very thin balsa instead of cardboard. At
: least then if it got wet it wouldn't lose it's structural
: rigidity, but would it weigh more? I guess one could weigh a
: sheet of thin balsa ply and compare it to the weight of
: cardboard. Probably a bit heavier I would guess, depending on
: the thickness of either material, and how many layers ply, and
: blah, blah, blah...

I didn't read the article at first. Would be a trick getting the filets to form doing it the way he's doing it. Normally with a honeycomb the skins are rigid and the trick is to get the resin right to form tiny filets at the edges of the honeycomb material. These filets are what gives the method it's strength.
