From: "Bill Church" Scotty, There's no real need to use streamline tube, unless you happen to have a piece lying around. The bellcrank isn't (well, it SHOULDN'T be) exposed to moving air, since it's enclosed in the fuselage. You could use round tube, and flatten the ends, or add tabs to attach the cables, or, as Jack has done, make up your own belcrank from two formed pieces of sheet metal. You could also make a bellcrank from a flat piece of steel, but you really should put a bend in it to stiffen it, since a flat piece would need to have significant thickness to be stiff enough without a stiffening rib, and "significant thickness" means extra weight. bill C.

Now I am talking five dollars for the best five minutes of your life." Last Friday my wife and I had the pleasure of hosting Eiichi Kurabayashi, a work colleague from Japan. He was attending a conference in Chicago and made the short drive to Madison to see our operation. Friday was all business with lots of bowing, me in a suit (I usually wear shorts to work), two-handed exchange of business cards (thanks Gary Boothe for the tip) and a business lunch. Eiichi let his guard down a bit and asked about hobbies. I told him I had a couple of airplanes and he looked at me and asked "Why two?" The obvious answer was because I did not have three! I asked him if he wanted to go flying and he immediately said yes. Plans were made for a Saturday adventure. We picked him up at his hotel in Madison and drove to Hartford, talking about cultural differences and really enjoying the drive. The weather was about 55 degrees and my plan was to take him up in the Cub with the window open but lower clamshell closed so he could take pictures and we could have the rumor of cabin heat. While prepping the Cub, he sat in the Piet with a helmet and goggles. My natural a$$holiness tried to take over and and shout the obvious WWII based stereotypes but the stink eye I got from my wife let me know that was not welcome. Taxiing to the gas pump, my new tailwheel was unlocking way too easily when applying rudder inputs. I decided, after going around the patch by myself, that it was not worth the small risk of scaring my guest on a slow groundloop if the tailwheel went into full swivel on the rollout. So, I looked at my guest and stated it was time for Plan B. 502Rocket was pushed out and we made a nice 30 minute flight around the area. I was in a hoodie and he kept the helmet on. It was a bit chilly but the windscreens Gene Pennington (RIP my friend) made a few years ago really keep the face area breeze free. The flight was a huge success and was capped off by a bratwurst lunch. Eiichi ate three of them. I really love sharing aviation. -john- John Hofmann Vice-President, Information Technology The Rees Group, Inc. 2424 American Lane Madison, WI 53704 Phone: 608.443.2468 ext 150 Fax: 608.443.2474 Email: jhofmann@reesgroupinc.com ________________________________ Message 13 ____________________________________ Time: 09:34:36 AM PST US Subject: Pietenpol-List: Re: four minute video of possible interest From: "Kringle" Very well done Mike! -------- John Read this topic online here: http://forums.matronics.com/viewtopic.php?p=372761#372761 ________________________________ Message 14 ____________________________________ Time: 10:30:52 AM PST US Subject: Pietenpol-List: Another Burned Valve From: "kevinpurtee" In January of last year the number 3 exhaust valve burned & failed on my corvair. One of the recommended vendors did a great job getting the heads re-done and back to me. The failure occurred at 190 hours. On March 31st of this year the same valve failed in the same way.

The Sainted Gary Boothe made me new ones which are going strong and look great. Anyway, as I was moving to a new hangar a couple of months ago I needed to get rid of the old struts. They would fit in the dumpster better if I broke them in two. Destructive Test 1): I put one end of a strut on the u-haul bumper and the other end on the ground. I attempted to stomp in the middle of the strut to get it to break. The only thing that came close to being broken was my ankle. It wouldve taken a lot more than my 200 pounds stomping on that strut to get it to fail. Destructive Test 2): Cut same strut half way through and repeated Test 1. Again, the only thing close to breaking was my ankle. Destructive Test 3): Cut same strut until less then was left intact and repeated Test 1. This time, after several stomps and much protest, the strut gave way. Destructive Test 4): Having determined that the only way to destroy the struts was to cut them up, I took the opportunity to inspect the delaminating portions. Turns out, the delaminations went in about 1/8 and the rest of the glue joints were intact. I've mentioned this before: the fitting attach bolt holes at the ends of the struts showed no signs of distress. Not exactly scientific, but it's real. The struts had ~260 hours and several hundred landings on them. For what its worth. -------- Kevin "Axel" Purtee NX899KP Austin/San Marcos, TX Read this topic online here: http://forums.matronics.com/viewtopic.php?p=372766#372766 ________________________________ Message 17 ____________________________________ Time: 10:55:03 AM PST US From: "Cuy, Michael D.

Basically you hook up a vacuum cleaner to the head so that the blower side of the vacuum pressurizes the intake. Then use a little soapy water and slosh it liberally around any place that might harbour an air leak. If there is one you will see bubbles. My friend here in McPherson running a Corvair with welded intakes on his Zenith 601 experienced detonation that forced rebuilding one of his heads. Turns out there was a pin hole in the weld that could not be seen with the naked eye but which showed up quickly with this test.

Knock Knock, the only valve issues we have had is lead build up on the intake valves, which was caught with a differential compression check. We were able to clean them without removing the head, with the old rope trick. I am hoping to get ours out this weekend after I get done shoveling gravel and working on the house. With any luck I might be able to make it to brodhead for a couple days this year. Good luck, if I can help with any advise let me know, if I don't know the answer I can make up stuff with big words.

Mine are AN3, with an AN5 bracket-to-wing attach. Brackets are about 6" long, with AN3's unevenly spaced from 1 1/2" to 2", in a straight line.....AND NOT FLIGHT TESTED!

Are those AN4's or one size larger? Are they lined up, or staggered a bit (can't quite tell by the photo, look lined up with each other)? What's the spacing (can probably come close with a educated guess, but if you have it handy...)? Lastly, insofar as "measuring carefully, no washout or anything, right? Just maintain the same incidence set by lift struts? Thanks again! Crazy quick, really appreciate that.

Left them at the mini-CC he had at his shop right after Brodhead, received at Brodhead the year after. Absolutely beautiful work (ask Tom S). I assume the lacks of heads will not be holding up your build progress......the lack of heads is holding up Kevin's flying progress (and quite a bit of progress he has made in that regard). If I run a small auto-shop in Southern WI, and also specialize in niche cylinder head work, and have X amount of time to devote to the things that keep the lights on.....where am I going to prioritize the time I have to do Corvair cylinder head work? To the guy I know that is flying the pants off his airplane, not the one that may be aways away from having an actual need for their heads (apart from just wanting to have them). That better supports the flying community of aircraft. No offense intended to you, it's just the reality of the situation. You'll get your heads, you just have to be patient (getting to the point of needing them would not hurt either)....they're worth the wait.

If the bolt holes on the fitting are staggered it's because I couldn't drill the holes in a straight line. I have used the threaded adjustment feature on the two aft fittings to make the airplane fly straighter. It would certainly be flyable without the adjustment but I'm glad I have the ability to tweak it. Gentle, hardly-noticeable turns are fine in the traffic pattern. They get tedious on cross country flights. A general thought for builders considering wood struts: if you're worried about the design considerations associated with wood struts then you may want to keep it simple and build to the plans. Can't go wrong doing that. -------- Kevin "Axel" Purtee NX899KP Austin/San Marcos, TX Read this topic online here: http://forums.matronics.com/viewtopic.php?p=372796#372796 ------------------------------------------------------------------------------------- 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.
