Also, it can be found in numerous websites as matters of public record. Here is the copy I made for my ribs. Notice that there is no angle built in. By that I mean the spars and verticals are perpendicular to the chord line. This is a full sized copy, and can be taken down to your local Kinko's and printed on their big printing machine for a couple of bucks a copy. It is free for anyone to use, but obviously done so at your own risk, much like everything else in experimental aviation. -------- Semper Fi, Terry Hand Athens, GA Read this topic online here: http://forums.matronics.com/viewtopic.php?p=454260#454260 Attachments: http://forums.matronics.com//files/riblett_6135_205.jpg ________________________________ Message 3 _____________________________________ Time: 11:14:34 AM PST US From: Jim Boyer Subject: Re: Pietenpol-List: Re: Pauls Piet Build Hi Ray, I don't know what you mean by U joints because the wings are slanted back 5.5" My wings are back 4" but everything lines up fine for the threaded fork on one end and the drilled blocks on the top end fastened to the wings ligr strut fittings. Are the fuselage or wing fittings different on the Sky Scout? Thanks very much for the photos; that is really what I needed to see to finish mine. Cheers, Jim B. ________________________________ Message 4 _____________________________________ Time: 08:19:01 PM PST US From: Ray Krause Subject: Re: Pietenpol-List: Re: Pauls Piet Build Jim, When I assembled my SkyScout prior to covering it, the struts would not fit i nto the wing fittings on the spars. The strut attach hardware on the spars a re parallel with the spars, so the struts have to be within a few degrees of parallel with the spars. That means the lower strut attach points have to b e pretty much right under the spar. On the SkyScout, the spars are about 6" behind the lower strut attach points. The struts pivot just fine at the l ower attach point with the swivel joint. See photo: Note that the bottom of the cabane struts are lined up with the lower attach points for the struts above the gear brackets. But the top of the cabanes ( they attach to the spar) are 6" behind the bottom of the cabanes. Therefore , the upper strut attachment hardware will not fit into the spar brackets! Therefore I made the "U-joints" for the top strut attachments. They fit on the wing like this: You may not have this problem on the AirCamper. I hope my explanation is understandable; it's a little hard to explain! Maybe I could explain it better on the phone, Ray Sent from my iPad > On Mar 28, 2016, at 11:12 AM, Jim Boyer wrote: > > Hi Ray, > I don't know what you mean by U joints because the wings are slanted back 5 .5" My wings are back 4" but everything lines up fine for the threaded fork o n one end and the drilled blocks on the top end fastened to the wings ligr s trut fittings. > > Are the fuselage or wing fittings different on the Sky Scout? > Thanks very much for the photos; that is really what I needed to see to fi nish mine. > Cheers, > Jim B. ________________________________ Message 5 _____________________________________ Time: 08:48:51 PM PST US From: "Greg Cardinal" Subject: RE: Pietenpol-List: Re: Pauls Piet Build Here is another alternative for dealing with lift strut ends. Greg Cardinal ________________________________ Message 6 _____________________________________ Time: 09:59:40 PM PST US Subject: Pietenpol-List: Re: Pauls Piet Build From: "taildrags" Ray; Now look, I'm not trying to cause trouble here, but I'm an engineer and I question stuff. You mentioned that you were using two AN3 bolts to attach each end of your lift struts to the strut end fittings. Then I see Greg's picture showing *four* bolts through the strut and fitting on his airplane. I have not done the analysis of the shear where the AN3 bolts go through the Carlson aluminum struts but it might be useful to do a little pencil and paper work to study that. Two bolts might not be enough to keep the bolts from elongating the holes under design stress, and it's not like you don't have long enough end fittings to permit you to add more bolts through the strut and fitting to provide more pull-out strength if it's needed. Worst case, it will cost you some additional AN3 bolts and hardware. -------- Oscar Zuniga Medford, OR Air Camper NX41CC "Scout" A75 power Read this topic online here: http://forums.matronics.com/viewtopic.php?p=454292#454292 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message pietenpol-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Pietenpol-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/pietenpol-list Browse Digests http://www.matronics.com/digest/pietenpol-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
