My 7th and 8th grade students have finally finished making the outboard wingsection ribs (3-piece wing, 26 ribs-needless to say, they are ready to moveon) to our AirCamper. We constructed the ribs with vertical supports on thefore and aft sides of the front and rear spar locations. We don't know howto support the spar locations on the ribs that form the butt joint betweenthe outer and center wing sections. Those locations are filled withplywood, steel straps, and pulleys. Those of you that built a 3-piece wing,how did you build those 4 butt ribs in the spar locations? Thanks, ScottCutler________________________________________________________________________________

Scott,Just trace the rib on to a piece of plywood, cut and glue. You can rasp &sand the plywood to fit after the glue is hard. Does that answer yourquestion?Gary BootheNX308MB

Scott, I commend you for doing the project with the kids. Not sure of youquestion but maybe some pictures will help. See here,http://textors.com/PietProject.html most of the wing pictures are at thebottom of the page.JackDSMNX1929T _____

actually i plan to rivet the lower brackets together and i will either make a newlower ash piece or glue more to the bottom in a rounded shape extending slightlyout to keep the bungee off of the metal..the legs are still roughjeffRead this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/leg_ ... ___Subject: Pietenpol-List: Re: center secting wing ribs

Scott,At first I didn't quite understand your question, but I think I get it now.The original plans for the ribs do not have any vertical supports at the spar locations.The full-size rib drawing as supplied by the Pietenpol family incorporatesa single vertical support behind the front spar, and a single verticalsupport on the front side of the rear spar. Some builders opt to install verticalsupports on both sides of each spar (4 supports per rib). I believe this isthe route that you have taken. This option does make it more difficult to slidethe ribs over the spars, but if you already have them built that way, it'stoo late to suggest not to use supports on both sides.In any case, since the original design does not have these supports, it is safeto assume that they are not structurally necessary. Therefore, you will not becompromising the structural integrity if you notch or remove those verticalsupports as required to clear any interference with metal fittings, etc.Hope this helps.Bill C.Read this topic online here:http://forums.matronics.com/viewtopic.p ... __________
