I have only flown it about 3 hours (it needed some engine work and some other small things). The plane has about 60 hours total on it. Recently when doing an inspection, I realized that the cross bracing between the lift struts on the right hand side of the passenger cockpit was missing. Further inspection revealed that it had never been installed. I have looked at the plans and they do not seem to indicate these. Question: Is this an optional item or do I need to place the cross bracing before further flights? Many thanks for any information that the group can provide, Jon Botsford ________________________________ Message 2 _____________________________________ Time: 06:42:46 AM PST US From: Michael D Cuy Subject: Re: Pietenpol-List: Firewall shaping --> Pietenpol-List message posted by: Michael D Cuy Ted--Bert C. is right on about one of the Bingelis books showing how to shape the top curve of the firewall. I used that method and all I used was a small drill bit and tin snips and a rubber mallet. Ok, I guess I made a 3/4" thick plywood template the exact shape of the firewall with magic marker spots where the engine mounts poke thru and various cables, etc. and rounded the edges with some coarse sandpaper and block to give the 1/2" bend some radius. On every hole to that I drilled on any metal---even those tiny holes where needed to bend the firewall over, I used a countersink bit by hand on both side of the drill hole for stress relief / to take out any burs or drill marks. (again as per Tony B's books.) Sorry...this is more than what you asked.

In on discussion last week about airfoil shapes I think the opinion of most is that it was a modified Eiffel. In the manual BP states that he tried many different shapes, including the Clark Y. He finally settled on a design that Don Finke , his neighbor, and himself, sketched out one night. He was told by experts that it was practically an Eiffel 36 with ordinates increased 25% all along the cord. It also states that the Eiffel 36 was used on the Curtiss Jenny. I also placed the 2 airfoil shapes from the Piet and the Gn1, side by side to see the differences. Although basically the same airfoil shape, there are some differences in the construction and leading edge shape, as well as the placement of the leading edge spar. If anyone wants to see this I can email it to them. Another interesting piece in the manual talks about the spars. It says" the wings are built up the regular way. Spars are built first( no dihedral, clotilde). does anyone know what clotilde is? I couldn't find any reference to the word on the net.

It has no aeronautical significance in the F & G Manual article. Although the article is purportedly written by B.H. Pietenpol, I suspect that Weston (Westy) Farmer had a hand in it since the writing style does not seem to be consistent with the speaking style of BHP. (My friend and I visited Bernard on our way home from Oshkosh, August 4, 1982. He had a great sense of humor, in spite having a painful hip, but somehow the text of that article just doesn't sound like him. We will always treasure the memory of that visit with BHP.) Westy Farmer, I believe, was editor of the publication and no doubt would have had input regarding the Pietenpol article. Maybe he knew someone named Clotilde???

One of the airplanes he's looking at is in Guthrie, OK and he only has verbal info and photos of it, so I'm trying to help find someone reliable who might be able to actually eyeball the airplane for a second opinion. Any of you good Pieters near Guthrie? Email me off-net; thanks.

The "jaws" are about 1" deep, to kind of work on a flange or angle piece to curve it. Have it on loan from my mentor. walt ----- Original Message ----- From: Subject: Re: Pietenpol-List: Firewall shaping > --> Pietenpol-List message posted by: ZigoDan@aol.com > > Ted, > > Use a metal stretcher or expander, neat little devices.

PS these guys talking about Tony Bingels way must have never seen the nice job a shinker will do. However I do realize the tool is expensive, and hacksaws, and drills are not making Tony's way a little more feasible for most. Dan
