Pietenpol-List: A couple of questions about wing construction

Post by matronics »

Original Posted By: "Andy Garrett"
Great pics! I like that he did the wire wrap/solder thing to his wires--very oldschool. Yet, at first glace his elevator control horn looks like a flat pieceof material, aluminum maybe?I've actually been wondering about that as I study for my build. What options havepeople used for control horns. I'm looking at ways to reduce the amount ofwelding to be done.--------Andy Garrett'General Purpose Creative Dude'Haysville, KansasRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: A couple of questions about wing construction

So, I have read that their is a discrepancy between the full size wing rib layoutprovided by Andrew Pietenpol and the actual stated dimensions in the plans.My own measurements confirm this. Go with the plans? Go with the stencil? Works either way?I also have a question about the three piece wing. The mounting method to the centersection looks as simple as one bolt per spar--at the bottom in the notch.This allows the wing to lower when the strut is disconnected.The method for covering the gap is not discussed (or I haven't seen it yet). Photosreveal that most use sheets of aluminum and a lot of screws. Is this correct?Other options?I also wonder if this is the area where we are to add the 1" dihedral mentionedin the manual to avoid the appearance of a drooping wing. I interpret this asmeaning that the wing tips are 1" higher than the center section, and that Iachieve this with a subtle angle cut on the spars. Is my thinking sound?--------Andy Garrett'General Purpose Creative Dude'Haysville, KansasRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

AndyI don't believe Gary was saying not to ask questions. I'm sure he wassaying that if you only ask questions to the list you will get a few answersfrom the people currently on the list. All beneficial but by searching thearchives you get the benefit of years of discussions by way more people thanyou would get by just simply asking. I've read through all the archives andthere are a ton of good things in there that new builders should know.Problem is I forget most of them so I have to go searching for them all thetime.ChrisSacramento, CAWestcoastPiet.com-----Original Message-----

...and don't forget to check out Chris' website, www.westcoastpiet.com,where you will see interesting things like this (speaking of alternativemethods of attaching those wing fairings, see attached).Gary BootheNX308MB-----Original Message-----

You can look here too: Pietenpol Plan Packages (https://sites.google.com/site/pietenpolplanpackages/)Remember adding dihedral will reduce lift. You will have some dihedral as thewing starts to fly. If you just want it for appearance then add in just enoughto give you that visual appearance, no more.Good luck with your build,WF2--------Read this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Ribs built to the drawing supplied with the plans will fly just fine.Keri-Ann Price used to sell plans for a gapless 3-piece wing. This was used on NX18235 and is a good option.As others have stated, www.westcoastpiet.com and the archives have a wealth of info. Enjoy the build.Greg CardinalMinneapolis----- Original Message -----

Thank you for your responses. Very helpful. I will make my horns as indicated inthe plans.As for my response to the suggestion that I should use the search feature beforeposting questions--I hope I did not come across as 'snarky'. That was not myintent.I have been a member of several forums over the years and understand the etiquette.I know it can be frustrating for the old hands to be patient with the newguys who seem to always ask the same questions. I will be cognizant of this inthe future. However, this would be a boring place if it were only treated as a repository ofstatic information to be researched like a common reference library. A forumis first and foremost a community, where ideas are fluid and dynamic. Askingeven an old question can inspire a new and creative response. So, I will be diligentin my search engine use before asking questions, but I may ask it anywaysimply to mine the current view of whatever it is. I will try not to be tiresome.Cheers!--------Andy Garrett'General Purpose Creative Dude'Haysville, KansasRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: A couple of questions about wing construction

Also, I discovered westcoastpiet even before I found this site. Very good stuffover there.I've also been pouring over every Youtube video I can find to compare and contrastmethods and configurations. Great stuff.--------Andy Garrett'General Purpose Creative Dude'Haysville, KansasRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Thanks, Andy. You are very kind! Yes, I get a lot of compliments at the airport, but I find that all veryhumbling as I consider myself fortunate beyond measure for having theopportunity to build this plane. There are so many who, for various reasons,do not have the time, money, situation, etc., will never have thatopportunity, or may take an incredibly long time to completion. I'mcurrently re-building a damaged Baby Ace, which grew up in the same era asthe Piet, but just doesn't seem to have the same mystique. I'm sure I asked my share of questions to this list, but found thatsearching through the archives yielded hours' worth of good reading thatwould often take me in directions that were unrelated but equally useful.Same for westcoatpiet. Looking through all those pictures helped me toquickly solidify an opinion about what I liked and what I didn't; roundedcorners on the tail parts, or not; tall wheels?; taller cabanes, orturtledeck? Deck angle? Cowling appearance? The list goes on...Color choice is something that will come sooner or later, but I think thebuilding process needs to be started with your vision of aesthetics, if thatis important to you.I look forward to hearing of your progress,Gary BootheNX308MB-----Original Message-----

Andy;I've lost track of this thread but in case nobody has mentioned this to you yet,by all means get Mike Cuy's build-and-fly DVD. You will learn a lot about Pietenpolsand building them by watching the video, but more than that you willget to walk around the airplane and get a running narrative of what's what andwhy it's that way, and you'll also get some really fun flying sequences. It'ssomething that you can pull out on a rainy day and just sit and watch witha mug of coffee and learn something new each time you watch it.You can search the archives on 'Mike Cuy video' or just wait for him to post theordering info here... I'm sure he will.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Fri, 6 Mar 2015 19:13:10 -0800
