The wing is upside down on the saw horses, so I just took the photos and flipped them. Oscar, I purchased the spar blanks from D&E Aircraft out of Lake Worth, FL. The front spar is 5.683" tall X 0.875" (I think). The rear spar is 4.625" tall. The taller spars were just a wee bit tight for the rear spar space. https://www.de-aircraft.com/other.html#04 -------- Semper Fi, Terry Hand Athens, GA Read this topic online here: http://forums.matronics.com/viewtopic.php?p=466625#466625 Attachments: http://forums.matronics.com//files/spar_spacer_2_155.jpg http://forums.matronics.com//files/spar_spacer_1_125.jpeg ________________________________ Message 2 _____________________________________ Time: 08:10:16 AM PST US Subject: Pietenpol-List: Re: FB From: "TriScout" come to think of it, ever since the newsletter went away, I can't remember if I'm a current member of BPA anymore.

And just to add one last bit to what I wrote about spar strength, changing the material from wood to metal makes a vast change in the strength, other things being equal. Spruce has a modulus of rupture (or bending strength) of about 9,400 psi whereas (to use a metal that is familiar to builders) for 6061-T6 aluminum it is 42,000 psi. If someone were to take the time to carefully route, dado, rabbet, and otherwise shape a spruce spar into the same dimensions and modified "I" configuration as your metal spar, not only would it be uselessly flimsy, even properly restrained it could only carry about 1/5 the bending stress that yours can.... Riblett or no Riblett. -------- Oscar Zuniga Medford, OR Air Camper NX41CC "Scout" A75 power, 72x36 Culver prop Read this topic online here: http://forums.matronics.com/viewtopic.php?p=466632#466632 ________________________________ Message 4 _____________________________________ Time: 04:51:38 PM PST US Subject: Pietenpol-List: Re: FB From: "taildrags" By the way: I just noticed that this thread, which began July of 2016 with a post by Douwe, morphed into a progress update by Ken Bickers of the rebuild of his damaged Air Camper (and the discussion of how he got his dog attached to the wall in the picture), is showing that it has had over 2000 views since then. I guess this is an indication of how much interest there is in expanding the Pieten-world into social media and friendlier user-group interfaces. Don't get me wrong, though... I still love it when I open the mailbox and a printed BPA Newsletter is there. I realize that the days of print newsletters are rapidly fading and that they are a lot more work than e-newsletters. -------- Oscar Zuniga Medford, OR Air Camper NX41CC "Scout" A75 power, 72x36 Culver prop Read this topic online here: http://forums.matronics.com/viewtopic.php?p=466650#466650 ________________________________ Message 5 _____________________________________ Time: 06:36:10 PM PST US Subject: Pietenpol-List: Re: Riblett to Spar Fit From: "Brent Wilson" Oscar, Terry Thank you very much for all the information and Terry for the pictures it helps me a bunch especially since I haven't actually laid eyes on any of this other than pictures. Oscar, beautiful job by the Engineering Dept. I actually grasped a lot of that. I'm just an old mechanic, but I have furthered the career of many an Engineer in my day so I kind of speak their lingo. The project I'm looking at trying to pick up has standard spruce spars, 612 Riblett ribs completed and the center section with the fuel tank completed, so I would probably just move forward with that design and build spacers to put between the top of the spar and the rib cap similar to yours Terry. Again thank you guys for all of your input.
