Pietenpol-List: Rib Design Question
Original Posted By: Isablcorky(at)aol.com
Have been pondering several hours over which rib is the best. Right nowI've got the full size template that came with the print set, themeasurements from the airfoil layout that I could plot, and a Cad file Iuploaded. They all have some things about them that just doesn't seem tofit. I know there will be some variations but just wondering what mostof the builders are doing.Has anyone put the airfoil on CAD other than the one thats onwww.aircamper.org. I sure would like to have a copy if so.Thanks for the help !!!Craig in SC________________________________________________________________________________

Yes,Please send it to me. And yes, I received my plans about a week ago andthere was a full size rib template. Maybe this is something new.Thanks...Craig-----Original Message-----

Tom, Would you be kind enough to share the cad drawing with me? MyPietenpol supplied drawing has become wrinkled , else I would use that as apattern. Has anyone tried to iron a blueprint flat again? Steam or nosteam?
I can get a full size printout here at work with your file. Canyou e-mail a file to the Governair address in the header? Since I drew my rib on the board it always looked funny, just notright somewhere. Last night I placed the supplied rib drawing over the topof the jig, and almost none of the top surface of the rib drawing lined upwith the jig blocks!! So I measure again, and find all the heightmeasurements of the rib are from the straight edge, not the bottom of therib!! The rib bottom was the proper height from the edge, but in someplaces the top was low by 3/8". I knew the rib looked flat on top, but Imeasured so many times how could it be wrong? So I unscrewed all the blocks/cams and have a flat board again. Itwould be nice to use a pattern this time around. In hindsight I justwasn't careful, and it bothers me because I spent enough time on this jig toget it right. Hope this is not a preview of things to come. At least Ilearned something. I have no desire to draw or loft the rib again, thistime I'll glue down the drawing, cover it with plastic and screw the blockson again.KentOklahoma City-----Original Message-----

I would like to through out a tip here:My plans for my Pober Super Ace had the same problem with the rib drawing,the coordinates given and the drawing were off. I regenerated the plan onCAD using the coordinates and the spline command and plotted. Yea, yea, weall don't have a CAD system but that's not the tip. I then took the drawingand cut a profile template on 1/2" plywood. The edges were sanded smoothand the bracing and spar locations were drawn on top. THAT became my ribmaster, regardless of the drawing or coordinates given.This was used as a tool in two ways. The first was to generate a rib jig.I simply tacked the patten on the base plywood and fastened the blocks rightup against the outside edge. I then marked the bracing and spar locationson the base and removed the pattern. The second use came when I fabricateda few plywood ribs. I tacked the pattern to the plywood and patern routedout the parts. They come out identical to the pattern.Robert HainesMurphysboro, ILP.S. - There was a third use, I did swat the cats off the worktable with ita few times.________________________________________________________________________________Date: Thu, 17 Jan 2002 10:26:34 -0500
