Hi, I am new to this list and this is my first post. I will be starting my Pietenpolproject soon and as I don't want to re-invent the wheel again, I was wonderingif anyone of you previous builders had a wing rib jig that you were donewith and would be willing to sell. Any help would be greatly appreciated. ThanksBryanRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Dear Bryan,Now, whoa there big feller, 'cause the thing you DON'T want to be buying isyour tooling!If they're not in your library already, go git a copy of Tony Bengelis'construction manuals. A lot of us wish Tony was with us today, but at leasthe left us his written word.You're going to find, I think, that when you feel confident enough to createyour own tooling (rib jig, fuselage jig, etc.) to make parts for your shipyou will truly be a homebuilder. Most of us on this list will assist you inany way we can.Otherwise, go buy a kitplane!Alan----- Original Message -----

Not only that, but what happens further down the road when you accidentally damagea rib and you've got rid of the one piece of tooling that's going to getyou going again.Jim Dallas ----- Original Message -----

Please address me as "Mr. Gravy"Anyway, I've checked the allowed attachments and .dwg and .dxf are not allowed.Attached is a pdf. The centers of the circles are the points as called out inthe F&G Manual. The smooth curve is the derived from the ordinates.MannyRead this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/airf ... ___Subject: Pietenpol-List: Re: Wing Rib Jig

OK, so by the over whelming response I will be building my own wing rib jig. Thethought, by buying one already made was not because I couldn't do it, I wasjust trying to save some time. I now see the logic in building and keeping myown jig. Next Question? Is there any difference or benefit by either soakingor steaming your capstrips, does one work any better than the other. Thanks Againfor the help and support. BryanRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Wing Rib Jig

There is a third option: ammonia fuming w/ anhydrous (spelling) ammonia. It's anadvanced method of bending wood. I'm not certain how it effects the overallstrength of the wood. The process basically destroys the integrity of the woodgiving it the consistancy of a wet noodle. Once all the ammonia is gone in Ibelieve 25 minutes or so the wood rehardens into its original state but with whateverbends it has been given remaining. You'd be able to tie those cap stripsinto tight knots if you wanted too. I don't know if this method has even beenapplied to aircraft construction. Much testing would have to take place toassure safety obviously before it could be applied.Imagine a continuous cap strip on wing ribs with no leading edges to make. Or,plywood made to bend into complex compound curves like the composite ships.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Wing Rib Jig

Bryan,I'm building ribs right now. I made the rib jig and posted some pictures of iton my site as well as my bending jig and other wing building accessories. Ialso crushed a sample gusset joint this evening as a confidence builder. I testeda method for quickly leveling the edge of the gusset with a router and alaminate flush trim bit so the top and bottom capstrips surfaces are smooth. Works very well and saves time. I just posted some pictures of this on my sitetoo. The funny thing is that none of these ideas were mine, all came folkson the list.--------Glenn ThomasN?????http://www.flyingwood.comRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: RE: Pietenpol-List: Re: Wing Rib JigDate: Fri, 21 Apr 2006 10:46:12 -0400

Has anyone had a chance to compare the smoothed rib from the pdf file with theirown rib? Is it accurate? I want to make a rib jig this weekend and don't wantto waste my time using a screwy profile.Read this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Thanks, The site is my answer to mykitplane.com before I knew it existed. Got most ofmy ideas for the jig from pictures Bill Church posted there. This project is allabout learning and sharing. My fear is that somebody may see my site andconsider me some kind of expert which needs to be made clear that I am not. I'mjust out there experimenting and learning as I go and having a blast.--------Glenn ThomasN?????http://www.flyingwood.comRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Fri, 21 Apr 2006 15:10:14 -0400

I've got a set of wing ribs that I'll sell you for $150 if you are interested in them. They are somewhere around 10 years old and were owned by others before me so I can't testify to anything about the building process other than that I know they are Douglas Fir and were glued with West System epoxy. I had pictures on Barnstormers as part of the ad where I was trying to sell the project as a whole with ribs, tail feathers, and fuselage but no one bought it and the ad has expired. I guess I'll sell it all separately if that works better.Email me off-list if you (or anyone else) has any interest and I can email pictures back to you.Thanks.Eric>From: "plncrzy" >Reply-To: pietenpol-list(at)matronics.com>To: pietenpol-list(at)matronics.com>Subject: Pietenpol-List: Re: Wing Rib Jig>Date: Thu, 20 Apr 2006 16:22:20 -0700>>>OK, so by the over whelming response I will be building my own wing rib >jig.
