We used gutter coil from our local gutter person. We bent it to match othertrailing edge profiles. This is not a very good pic and can take a betterone if you need it. Be sure to sand with rough sandpaper each spot it isepoxied onto the rib. We did not use nails, because the fabric will hold itplace later.----- Original Message -----

I re-checked the C. of G. and moved the wing backto 3.5" aft of vertical, and it caused the turning circle to be noticably wider...probably because of the added weight on the tail skid. As far as getting in and out, it didn't make any difference, because I still had to slide my back across the bottom of the wing, no matter what position the wing was in. As far as extending the nose, it is said that it is more difficult to bring it out of a slip...which makes sense. However, for my experience, I havefound that the rudder is very effective at bringing 'er out of a slip...no problem. I usually slip it in on final, maintain 60 mph indicated, (don't wantto get slow in this configuration, or it will spin) and less than 1000 rpm on the ol' Continental. Practice slips at altitude in your practice area, beforeattempting it on final, and do so just a very little bit at a time. In a slip,the windshield blocks only a small portion of the relative wind, and it can bea bit distracting having all that wind in the face. This is the only time I have to noticably hold forward stick to maintain airspeed. The ball is all the way off to the side. The decent rate is very high, but it is good standardprocedure, because I can maintain plenty of altitude in the pattern, should that big fan stop blowing, I could still make the field. Bring 'er out of theslip, just before making the numbers (or if the engine quits), pull power to idle and she slows down quite rapidly as I round out. Closer and closer to theground, keep aft stick, ASI passes down through 40 mph indicated, wind noise diminishing, hold 'er off...hold 'er off, inches to go, hold 'er off, if neededkeep the upwind wing a little low, then usually the tail touches just before the mains. I can usually grease 'er on, with a short roll out, 3 out of 5 landings, and boy does it feel good !!

Thanks Mike=2CI figured yours would be pretty much to plans. The only thing that made me question it was pictures of some of the ribs people have been makin'. I'm kind of an "if it ain't broke don't fix it" kind of guy. Mine will be to plans...Including the Model A. Don't hate me because of I'm a Model A. LOLDoug DeverIn beautiful Stow Ohio

Just to throw another thought out there, I am about to attach my trailing edge like Mike did (except that I made mine out of ripped up pieces of Stearman spars) but I think I am going to use popsicle sticks instead of plywood to attach it (the wide ones, from a craft store). They are a bit thinner than most of the ply I have on hand and they are good and strong and very easy to work with, almost no cutting -- just cut them in half and bevel the edges. Besides, most old wings I have taken apart have had the plywood delaminating long before the solid wood has deteriorated.anyone else done this??Gene ----- Original Message -----

Great thread... I have been contemplating this very subject myself for severaldays. Thanks for the illustrations Mike, and the photos Jim. I like the idea of the wide popsicle sticks... I have a box of 500 of those thatI bought for mixing glue. Way more than I need, plus I like the smaller onesfor most stuff. I also like the tongue in grove method, which is what I originally planned to do,and still might. My biggest problem at the moment is that I left my ribs (topand bottom caps) too long at the trailing edge. I built them according tothe rib drawing, but I didn't realize that I was supposed to trim the excessuntil I started looking at other parts of the plan, and now those suspicions areconfirmed in Jim's photos. Looks like I get to slide the ribs back off the spars for a trim (bummer). I wonderif I could just shoot a laser down the length and trim them with an exactosaw?--------Mark - working on wingsRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Good idea. BUT. Those things are cut anywhichway so I would test each onefor short runout by breaking the "other half".Clif Subject: Re: Pietenpol-List: Trailing Edge I think I am going to use popsicle sticks instead of plywood to attach it (the wide ones, from a craft store). anyone else done this??

Gene,Not flying but that's what I did. I also made a jig to hold the rib on thetable saw. Starting with the blade below the table I cranked it up 5 turnsfor each rib. For extra bracing I glued a 1/8" triangle piece of birch plyin the TE groove on both side of the rib. Try wire or aviation snips to cutthe sticks These pics may help.Jackwww.textors.com _____

I believe that these tabs are to give more bearing surface for the fitting when on the ground. When you look at it, at rest all of the engine weight is pushing the lower fitting aft. These ears take some of the load off of the attach bolts.Gene ----- Original Message -----
