From: "Dale McCleskey" Congratulations. You obviously couldn't do better than getting Dick's workmanship. On route. I'm in Lebanon, TN (M-54) we have a grass strip, so come and see us. Then on the trip to Brodhead I've used Ohio County (7K4) no grass, but it's a good place to stop and friendly people, then due to various weather conditions I've used Sullivan County (SIV) and Vermillion (DNV), Pontiac (PNT), and Dixon Walgreen (C73), though my favorite of all it Dwight, Ill. (DTG). You get a grass strip in a soybean field and to meet the elderly couple who run the tiny airport. After they'd fueled my plane, on the way back from Brodhead, I found they didn't take a credit card. They gave me a ticket and said mail them a check. Such folks are what makes low and slow so extremely worthwhile because of the people you meet along the way. -------- Dale McCleskey N7035N Read this topic online here: http://forums.matronics.com/viewtopic.php?p=353627#353627 ________________________________ Message 2 _____________________________________ Time: 08:46:41 AM PST US Subject: Pietenpol-List: Re: cable tension From: "K5YAC" All I know is "ping" is too tight. -------- Mark Chouinard Wings, Center Section and Empannage framed up - Working on Fuselage Read this topic online here: http://forums.matronics.com/viewtopic.php?p=353634#353634 ________________________________ Message 3 _____________________________________ Time: 10:47:36 AM PST US Subject: Pietenpol-List: Re: machined control horns? From: "dgaldrich" Has anyone tried doing the control horns in sheet aluminum? I'm thinking .032 2024T3 bent like the steel ones but edge riveted. Might save a pound or two on that long lever arm back to the tail for cg and would be easier to corrosion treat. I have a guess that they would be strong enough, though not as strong as the steel version. The question is just how strong is strong enough. Since control surface travel is limited by physical stops in most cases, the max load would be aerodynamic. Any engineers out there have a clue on the aero load forces? That sort of math makes my head hurt.

I have a suggestion. How about having a workshop set up where everyone that is new to the game can learn all these new tricks. I would like to learn how to make those control horns instead of using flat steel. We are getting a lot of questions on how to do things that I think are simple,but then , again, I am simple. I think that with all the tools that are available in Brodhead we could set a workshop for our use. I can learn a lot better with hands on than listen to someone talk for an hour. My 2 cents worth. Gardiner. PS New ribs are done and now to build new wings. Always thinking of the next Brodhead trip ________________________________ From: "helspersew@aol.com" Sent: Fri, September 30, 2011 7:41:41 PM Subject: Re: Pietenpol-List: Re: machined control horns?
