Two questions for you all 1. did you steam your bottom longeron to get it to bend or did it bend ok without steaming? 2. does the plywood on the sides need to be from one piece or can you piece it from two or three smaller pieces?

Campbell" Subject: Re: Pietenpol-List: longerons and plywood? I started out steaming the lower rib member. However I discovered by accident that the lower member does not need to be steamed. The curvature is not that great. I didn't put plywood on the full rib on ANY of them. The root and tip ribs have extra vertical members and that is apparently all that is required. When I covered the wings, I put fabric on the surface of the root ribs.

Today I got ahead of myself (AKA Had a brain fart) and hit open before I unlatched the door. It stopped when it got in a bind and tripped the reset switch. Miracle Span is out of business. I got on the Schweiss doors website and sent a contact email. I was texted a number to call within 5 minutes. I called Dave and he told me exactly what to do even though this was not a Schweiss door. Apparently Schweiss sold bifold doors to Miracle Span. Then Miracle Span copied them and went out on their own and later went out of business. Great service on a Sunday on a product that was not made by them. I will look at them if I ever need another door. -- Blue Skies, Steve D ________________________________ Message 4 _____________________________________ Time: 03:09:55 PM PST US From: "Clif Dawson" Subject: Re: Pietenpol-List: longerons and plywood?

I'm finishing up three sets today that will bring the waiting list to less than 25 on the waiting list now. I am not offering them in ready-to-install condition anymore, but I do all of the rough shaping and the operations that require jigs (drilling/countersinking the base mounting holes and cross-drilling the holes for the hinge pins). The cost for a set of 9 pairs of hinges in this condition is $45 USD, postage paid in the US. However, I do not take deposits or prepayments... you only pay when your parts ship. I have found that I can turn out 3 sets of these semi-finished hinges in a weekend, so even if I worked at cranking them out every weekend, I would still be a couple of months behind. Unfortunately, I rarely have any time off these days so it's just a hit-or-miss affair. Plus my work area is outdoors so when the weather is bad, I'm not motivated to get out there and stand at the workbench for hours at a time.

I had debated and debated then after my talks with PF Beck, decided to bite the bullet. After my first flight I'm really pleased. Can't tell how much, because of the Johnson vane-type airspeed indicator, but my stall speed has been reduced noticeably. She's always stalled very mildly, but she is noticeably "rock solid" feeling just before the stall which is even milder I think. The slowest I used to be able to maintain altitude was around 1700rpm, now I think she's maintaining altitude in the 1500's. Don't notice a reduction in cruise speed. Overall, I'm stoked. they're small and clear so they're hard to see, though you can see them at three-point attitude if you step back and that certainly isn't vintage, but I think it's worth it. that's about the only drawback I can find so far.

Some of you may have heard that the Brodhead Pietenpol Association has changed hands. A group of us at Brodhead Airport have agreed to take the reins from John Hofmann and have committed to publishing four newsletters per year, along with planning the annual Pietenpol Reunion at Brodhead Airport. A new website is up, and while it is still being built out with content, you can go there to join or renew your membership, download selected back issues of the newsletter and join other builders and enthusiasts in the discussion board. http://www.pietenpols.org The discussion board is a new feature meant to bring a much updated version of the Matronics board back to the "mothership." Also, we are starting to scan many of the original newsletters from the early 1970s and 80s that are full of good information from the old-timers. As always, we appreciate any information, articles, photos, ideas and general gossip that you all can provide for the newsletter. Contact information at the website. Thanks to John Hofmann for his work over the past several years.

Blue Skies, Steve D ________________________________ Message 15 ____________________________________ Time: 09:32:23 PM PST US Subject: Pietenpol-List: Re: Vi Kapler hinges From: "taildrags" 'wheelharp'- I do not make the castings myself... I have them cast in batches as needed, by a secret source somewhere in middle America to which I'm very grateful for making parts that could possibly go into experimental airplanes but then again might just be hinges for handmade jewelry boxes. If you know what I mean. I'm just not sure that my source will still be available next time I'm out of castings. I would be happy to send you some of my reject castings to examine if you're interested in making your own molds and parts... just let me know. Happy to let you tap into the millions of dollars that are out there to be made, easy money, hand-fabricating hinges for Air Camper tail surfaces. I'm easily on my second million already (hours, not dollars ;o) I have no idea which specific alloy is used in the castings but from load testing it and machining it I can tell you that it's tough, strong, and just a bit brittle. I think it's A380 but don't know for sure. It is good material for these parts. You can see the general steps of how the parts are made from the rough castings here: http://www.flysquirrel.net/RogueAir/hinges.html . You can see the results of my load testing of a set of the hinges here: http://www.flysquirrel.net/loadtest.html . They are very stout pieces, and quite a bit of the rough cast surfaces can be machined and polished away to make them pretty without diminishing their strength very much, but not much was done to the ones on my airplane to pretty them up and the only thing I would do if I had the time and inclination would be to square up the faces of the two outer tabs so that the head of the clevis pin and washer under the cotter pin on the other end of it would fit flat and square. I think if I did this, I could get clevis pins that might be one AN-dash size shorter than the ones that are on there now and save perhaps a gram of weight out there on the tail ;o) -------- 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=466915#466915 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message pietenpol-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Pietenpol-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/pietenpol-list Browse Digests http://www.matronics.com/digest/pietenpol-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
