Subject: Pietenpol-List: Re: Root Rib This is the way I did it on my plane too. I would only add that if I wereto do it again, I would add a bridge strip between the root rib and the onenext to it. My fabric over the past two years has pulled the rib toward thetip slightly causing a slight pucker. Adding a spar cap would prevent this.Stevee***************Steve, did you install the 2" 1/16 plywood bracing strips along the top and bottom of the root rib, and the diagonal bracing to the top and bottom cap strips in the bay between the spars? Mine seems pretty sturdy with that, but I haven't covered yet...Matt Paxton________________________________________________________________________________

SteveE here,I did install the 2" x 1/16" ply and the diagonals... The problem is at thespar itself. two nails and a dab of glue isn't enough to hold the rib inplace. the rib is pulled outboard on top of the spar. The fix is simply toincrease the surface area of the glue joint at each intersection of rib andspar on both front and back spars. A small wedge of scrap to back up therib or a full piece between the root and the root plus one rib would do thetrick. Every where else the rib has stayed in place.Steve E-----Original Message-----

"Michael Conkling" Hi CorkyThe Trig way to find isn't too bad if you have a calculator -- what you wantis the TAN of 1 1/2 degrees -- this times the distance out will give you therise (you really should use COS, but this way will get you close enough! ;-)Another way is to use the fact that 1" rise in 57" (+ a bit!) will give youan angle of 1 degree -- sometimes this is more useful than trying to layoutsomething with a protractor. Up to about 15" of rise (to the 57" run) youare within 1/4 degree of the "protractor" angle.Mike C.Pretty Prairie, KS----- Original Message -----

In flight, acording to Bernard and Vi Cappler, it will do very little...if anything. The design of the wing tips tend to be a substitute for digedral. During static display, it will deter from the classic lines of a Pietenpol, or for that matter any vintage aircraft. In my humble oppinion, you should rig the wing straight, with no washout. Keep it simple and easy. If you keep the ball in the middle during flight, a hershey bar wing will inherently stall inboard first, eliminating the need for washout.Chuck GantzerWichita KS________________________________________________________________________________Date: Tue, 17 Oct 2000 05:34:13 -0700 (PDT)
