Thanks all for the input.One more question. The plans show leading edge material only on the top,has anyone wrapped it around the underside also? Would there be any benifitto this?Dick Navratil________________________________________________________________________________

I like the idea of wrapping around the leading edge to 3" on the bottom sideand to the spar on top. I was looking at rolls of aluminum in ACS, not wideenough. I am going to check out the rools of aluminum roof flashing stock ahome building store. It comes in a variety of widths. I don't know aboutthickness yet. Something .016 to .020 would be good.Dick Navratil________________________________________________________________________________Date: Tue, 12 Dec 2000 17:17:27 -0800Subject: Re: Pietenpol-List: leading edges

Subject: Re: Pietenpol-List: leading edgesI just don't see any advantage at all, of extending the plywood around the tight radius of the leading edge, and extending it under the wing. The disadvantages would be weight, extra work, and expense. When my plans built, one piece wing was complete, with paint, it would easily twist 4 or 5 inches. The 1/16" plywood, as opposed to 1/32" plywood, offers better rigidity for cleaning the wing, and protection against bird strikes...on the other hand they say Pietenpols take bird strikes from the rear !! Aluminum has a different expansion rate than wood, and I'm sure, over time, would loosen up the nails, especially on a one piece wing. Most aircraft aluminum is 2024 (copper alloy for strength, but corrodes more readily). Any flashing type aluminum is 1100 (soft, malleable, and very corrosion resistant). Some designs use a 'D' box in front of the front spar, but the aft edges of the plywood is glued to the top and bottom of the front spar, to help check torsional load. On a Pietenpol, the two lift struts do that. In other words...Follow the Plans, and you can't go wrong !!Chuck Gantzer________________________________________________________________________________Subject: Re: Pietenpol-List: leading edges
