Did anyone catch Douwe on Fow and Friends this morning? He and members of the Army who served in Afganistan were on being interviewed about Douwes sculpture. It was a great segment and lasted about 4 minutes.Great job DouweDick N.________________________________________________________________________________Date: Sat, 12 Nov 2011 03:29:52 +0000 (UTC)

Finally made it over to see Tim and his Piet!Great guy and it sure was nice of him to let me sit in his aircraft and ask a bunchof questions. I'm glad I got to sit in one finally. At first i didn't realize that his wing is2" taller than the plans. I guess I'm going to have to do the same for ours.I also liked his raised turtle deck. Next time I'm bringing my dad... I'm not so sure he'll be able to get in and outvery easily. Anyway i sure am glad i now know someone locally who has a piet whom we can goto for help. Thanks guys!Read this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Hi John,The ribs on NX18235 were built using spruce. I didn't pre-bend either the upper or lower capstrips. They went directly from the boiling water into the rib jig. I allowed the capstrips to dry and cool before installing the gussets using Aerolite.This worked very well for me.Greg Cardinal----- Original Message -----

Subject: Pietenpol-List: RE : Under camberI agree with John. Without the under camber, it's a different airfoil. Might have better characteristics - might have worse but it's different. I didn't find covering the undercamber difficult if you follow the instructions in the PolyFiber manual. And, the under camber is a conversation piece.Matt Paxton________________________________________________________________________________Subject: Pietenpol-List: Re: Douwe Blumberg

Gotta say that changing something as critical as the airfoil, just because onethinks it will be "a pain to cover" sounds like a drastic course of action totake, with unknown consequences. Sure hope that anyone considering such a movewould do all of the necessary homework to anticipate all of the repercussionsthat would result.On another note, Michael, you say that the Riblett 612 has a gentler curve underneaththan the Pietenpol FC-10 airfoil. I agree that the undercamber is lesssevere, but I believe that there is MORE curvature towards the nose of the rib(see attached comparison of the two airfoils). Whether this requires pre-bendingis another question. Sounds as though some builders have felt it necessaryand some have not.Personally, I built the Pietenpol FC-10 ribs, and did not need to pre-bend thelower capstrips.Bill C.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/fc10 ... ___Subject: Pietenpol-List: Re: Wing rib question

FWIW... I pre-soaked/bent my top and bottom capstrip. Not sure if it was necessaryfor the bottoms, but it was a matter of cutting a simple form from a scrap2x6 and clamping a batch in place every few days when I was building ribs. Had to do it for the top caps anyway, so I doubt that it added much to my overalleffort. I will say that I didn't have to fight any of the caps on my jig,and the ribs came out as near to identical as I can tell. If I were to do itover, I would do it the same. As for ease of covering... in the early stages of planning I was considering acylindrical wing. No bends, no curves, no corners, no sharp edges and I couldjust roll them out of the way when I wasn't working on them... the ideal coveringjob. But, it got very complicated on the drawing board because I kept confusingthe LE and TE. Not sure how it might have flown, but hey, at least thecovering would have been easy.--------Mark ChouinardWings, Center Section and Empannage framed up - Working on FuselageRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Mon, 14 Nov 2011 13:26:19 -0600
