Will,



A friend here with a Heath told me that he got his "canvas" from a local upholstery shop.  You don't really want canvas or nylon, like a lawn chair.  You want the stuff they put in couches and easy chairs-- the stuff that is rubbery and stretches.  That is what I would use if I had room for a frame and such webbing.  Instead, as I metioned in my last note, I am going for some ply contour and some contoured stiffer foam.

Thanks, Gardiner.  My seat height and general construction are fixed.  I think the aluminum you suggest would work well.  Right now I will be fooling around with 1.5mm plywood to get the contour, and then fill the gap with marine foam.  That will give me simple curves in one plane (fore-to-aft), then I am planning hip-hugging right-to-left with that stuff they put down around jungle gyms and the like.  It doesn't give much, and is very light.  One piece of that will be my only back padding except for some Insulfoam (like football shoulder pads) in the lumbar region (where I already have a broken vertabra).  It should barely fit there and still allow me to slip into the plane.  



I have fore-to-aft fit problems, as Corky can attest.  He made the fuxe 3" wider than plans and my elbows fit inside, which the standard plans do not allow.  Plenty of left-right butt room, too.  



For the final padding on top, I got something like the tempufoam from Wicks (1", blue foam, as I recall) and that makes an enormous difference, but I need more contour first.  



If the ply doesn't work for me, I will look into aluminum.

Tim, I don't think the plywood will work cause it might break. The aluminum won't break. It is screwed down along the back ledge and angled over the front ledge and screwed along the front giving me plenty of contour. I do have a gap at the bottom of the contour and have not worked that out yet. I have the long fuse and 2 inches wider. It is quite roomy. Gardiner.
