Subject: Pietenpol-List: friends across the hallwayAnd of all places here at work Mike Perez moved here to my building from another area on the lab (we have about 3,000 folks here at Glenn Research Center)and he started helping us out with our work in this test facility. We didn't even know we shared the same aviation bug until after we worked togetherfor about six months and since then have become good friends---over what? A Pietenpol Air Camper. Very cool stuff!EAA's founder Paul Poberezeny has said over and over again that it's not about airplanes it's about the people, the friendships that develop. He's right.I have some wonderful friends thru this Pietenpol world-some talk with southern accents, some are Canadian, one is a Calc professor, the other knowsWisconsin like the back of his hand. Then there's this Jim Markle guy:). He's a hoot!Mike C.________________________________________________________________________________

>From my expeience with my short "2 into 1" exhaust pipes on my A65, burningyourself might be a problem if you reached down to the pipe in flight (whywould you do that?), but the pipes cool very rapidly upon engine shutdown.I have to reach between the pipes on my exhaust manifold to check the oiland it is usually cool enough to do so less than 5 minutes after engineshutdown. As far back as the cockpits, it will cool even faster.Are you considering stainless steel pipes, or carbon steel? If stainless,they will need to be TIG welded, and I can pass on a tip that I learnedafter ruining my stainless steel exhaust: When TIG welding, the argon gasprovides a shield around the weld to shield the molten metal from the air.However, when welding something as thin as exhaust pipes (typically .035"thick), the back side of the weld gets just as hot but is not shielded bythe argon cloud. In order to protect that area, the whole pipe must beflooded with argon (you can test to see if there is enough argon byinserting a lighted match into the pipe. If there's enough argon, the matchwill instantly go out), and then plugging the openings to keep the argonshield in place while welding the outside of the pipe. Does that makesense?My current exhaust system is made of carbon steel, which works fine but mustbe kept painted (I find I have to remove it from the airplane, beadblast andrepaint it about every 3 years). I use clear VHT paint which makes it looksomewhat similar to stainless steel.I listened to the YouTube of the SE-5 and couldn't tell much difference inthe sound from my 2-into-1 setup (listen here:http://www.youtube.com/watch?v=9DTmKApOPyw ). Maybe if the long pipes weremade much larger diameter they would resonate more. Certainly does lookcool!Jack PhillipsNX899JPSmith Mountain Lake, Virginia _____

I decided to remove one of my tapes I was unhappy with. It was VERY difficult to pull off. So the adhesion is good. Just make sure the excess glue is wiped off immediately.Otherwise it will leave telltale streaks.Dan HelsperPuryear, TN-----Original Message-----
