of course, they are "Ribs are Done!" :DJust finished my last wing rib today. Well, not quite done. I have to-1. Trim the nose of the ribs for the leading edge piece, as yet to be built.2. Rout the gussets where they are "proud". (always loved that word when talkingabout building)3. Trim the tail of the ribs to prep them for the trailing edge piece, as yet tobe created.But I am at least finished with the jig. Progress!But I have one question-Tony Bingelis suggests NOT putting the ribs together on a set of short faux sparsto sand them. He says it is better to trammel the wings and then sand two orthree of them at a time with a long sanding board. To the builders who havecompleted your wings, does it really matter, as Tony suggests? Your thoughts areappreciated. P. S. On to the tail feathers!--------Semper Fi,Terry HandAthens, GARead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Your Favorite Words to Hear in a Georgia Restaurant?

Terry, Congrats on the ribs! What is it that you are sanding on the ribs? Areyou talking about your gussets?

John,I should have made it more clear. I am talking about after routing the gussets,then sanding the capstrips to even up any minor differences between the individualribs, and in order to ensure their uniformity.--------Semper Fi,Terry HandAthens, GARead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Your Favorite Words to Hear in a Georgia Restaurant?

I didn't sand mine at that point. When they came out of the jig they were allVERY much the same. Had I mounted them together and tried to sand them to a evena tighter tolerance, I probably would of made them worse. I did sand thesharp edges round so they would not cut the fabric when it is applied.--------John FrancisRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Your Favorite Words to Hear in a Georgia Restaurant?

Hi TerryThink about this. The ONLY place the wing will have the profile of the jig isdirectly on top of the rib. The rest of the span between the ribs, the airfoilwill be some slightly warped version of the airfoil since the fabric isn't rigidand will always have some degree of sag. This means that somewhere between90 and 95% of the wing will have some curve similar to but not exactly likethe jig. If you were covering them in plywood a la Wittman Tailwind/BellancaViking, it might be worth the effort to make them exact, but for fabric, I suggestthat the way they came out of the jig is close enough. Trim them up, makesure there's no sharp edges to irritate the fabric and go forth.DaveRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Your Favorite Words to Hear in a Georgia Restaurant?

Jarhead!!!1. Congrats!2. Sanding. Don't matter. Built HUNDREDS of model airplane wings with tons ofribs doing every method on the books to ensure uniformity (straight wings, taperedwings, eliptical wings, gang sanded, two to three ribs at a time, the wholewing at a time... ). It just doesn't matter. It'll be fine.Knocking the edges off IS important. It's VERY tedious, but will help the fabricimmeasurably. 80 to 100 grit sandpaper on a wood block will do the job wellfor doug fir, cedar, poplar or spruce. Go for a just noticeable round over.3. C'mon... you know I know better than that, ribs are done in GA whatev... Normal"pros" might think Kansas City, Memphis. We both know the saying is bestreserved for Dinosaur's, in upper New York. Just sayin'. 4. Congrats again!Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Update from: Corky's Rib Building

For What It's Worth department...Aeronca Chiefs use 1/4 x 1/4 sitka for their ribs. I would think 3/8 doug firwould be up to the job in the Piet. The 1/4 x 1/2 per plans is probably a LOTof overkill, sort of like the aft end of the fuselage.DaveRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Your Favorite Words to Hear in a Georgia Restaurant?

Terry,I would have found that very cumbersome and completely unnecessary (Sorry Uncle Tony). If your spars are close to perfect (most are) then it follows that the wing surfaces will be also if the ribs are identical to each other, and placement and relation to the spars is the same.Dan HelsperPuryear, TN-----Original Message-----

Thanks to all for the words of wisdom. I will round off the edges of the gussetsafter routing them flush and call it a day.Thanks again.--------Semper Fi,Terry HandAthens, GARead this topic online here:http://forums.matronics.com/viewtopic.p ... __________
