Thanks Andrew,

In addition to my "normal" flying in 172s and Cherokees, I also had every Hang Gliding rating save one (wire assist take off on a cliff with someone laying on their back, holding my flying wires while i was essentially flying before i left the ground) and many hours in a Max Air (3 axis) Drifter. You really feel the wind on your wings- like sailing!

why does this not surprise me, bruton. is there anything in this wide world you have not tried to risk your life with?

and it looks like baldeagle is trying the same with that autogiro. you're nuts, man!

AAC, that Y chromosome is a real cross to bear, let me tell you, missing that entire extra leg and all. but it looks like you also suffer from a similar malady- the Call of the Wild! Just the fact that we are all active in a forum of this nature is a hint that we are eccentric! i love it!

Working on my lower wing, right side.

Photo 1: fitting the plywood skin to the leading edge

Photos 2 & 3: Front view of angled front of rib: follows landing gear angle! also moved 3/8" to the wingtip from the rear of the rib- note straight edge showing gap in Photo 3.

Photo 4: overall view.

Back to work!

here is what the front of the lower wing looks like once the ply is on, and here is a closeup of the ply skin on the inner most (canted) rib.

Just as a tweak to the plans will make the lower wing fit better where the landing gear is concerned, same for the center wing cut outs. You have already seen the rear web modifications made a few posts back. To make the center wing cutout itself, and its support, you can either go the traditional method and laminate curves pieces together and then route them out (or something like that), or you can modify Ron Sands support, which I am doing. It is very strong and provides a ton of support, especially when the covering begins to pull tight. I will add some 3/8" triblock on the top and bottom (wetting or steaming to get the curvature I need) to add to a sandable trailing edge so I can get the correct trailing edge contour. More later!

Jim,

Are you going to cover the spar of the lower wing with aluminium plate as per original??? Under the fuselage only offcourse.

Willem, thought about it but as the alum goes up within the wing several ribs, i did not. However, I may change my mind later and figure out a way to work it in- at least in the middle open area- thanks!

Jim,

My original drawing No.30052 shows that only the part between the inner ribs is done. Original text: Der Holm ist auf dieser Lange (lenght between the inner ribs) mit Aluminiumblech, 0,3mm stark zu beschlagen und links und rechts mit den Anschlussrippen zu vernagelen. The aluminium is bent for approx a centimeter up, down and to the sides on the ends and then nailed to the inner ribs.
