Some model of a Piper? Cessna? T-craft? etc. If so, I'd appreciate the details . . . ALL the details.

Most old hangers have them in the rafters. Visually , they look to scale. And you lop off about a foot from each end anyway, so you can inspect the interior. Mine still were damp with preserving oil. walt evans NX140DL ----- Original Message ----- From: "Richard Carden" Subject: Pietenpol-List: Which wing struts? > --> Pietenpol-List message posted by: Richard Carden > > Is there any conventionall wisdom (aka "been there, done that") about > wing struts used by certified aircraft which are suitable for the Piet? > Some model of a Piper?

I would love to see them. And are you making it down on the BIG trip? Max and I are sure looking forward to you being here. We'll both have a place for you to stay, etc. Hey, I actually get to go out in my workshop today!!! WOOHOO!!! It's been several months and I'm not liking it! hope you get to do some flying this weekend.... later, jm -----Original Message----- From: Rcaprd@aol.com Subject: Pietenpol-List: Give me a Brake --> Pietenpol-List message posted by: Rcaprd@aol.com Ah, yes...the good ol' days, when I didn't have brakes (last spring), and things were much simpler. Now I have quite a few more things to check on pre-flight, items that might fail (if it ain't there, it can't fail), and I have to carry this extra 6 or 7 pounds around on each flight. I use the brakes for maybe 30 or 40 seconds on each flight - mag drop / run - up, and a little stab here and there to taxi...that's it. I never use them to slow down. Therefore at first thought, it seems they are just not worth having, especially after having oporated my plane without brakes for about 30 hours. It handled very well with the tail skid, and no brakes...as long as it was on the grass. Taxi on the hard surface, and it was like a fish out of water...limited or no response to rudder input, and a small breeze on the tail would have its way. One of the squawks I had to take care of, was a leaking master cylinder, so I had to remove all the stuff under the front seat, and while I was in there, I cleaned, sanded, cleaned, sanded, cleaned and re-varnished the front pit. On the plus side, the oporation of the heel pedals, and break control is very good, and fairly comfortable. In conclusion, if you're going to do any cross country flying, where hard surface oporation is inevitable, brakes and a tailwheel is are required equipment, but they sure are a pain.

If anyone wants to see them, just e-mail me direct, and I'll e-mail you the pictures. ________________________________ Message 4 _____________________________________ Time: 11:06:20 AM PST US From: Rcaprd@aol.com Subject: Re: Pietenpol-List: Give me a Brake --> Pietenpol-List message posted by: Rcaprd@aol.com Group, I just sent six pictures to Matronics Photo Share, but I've never done it before, so we'll see if I did it right. I got quite a few requests, so I did it this way. The pictures of the final assembly, as it is in the plane, is still in my camara, and my camara is still in my plane...I knew I forgot something when I left the airport Thursday !! I'll get some detailed dimensions the next time I'm out there, and try the photo share again.

I'm printing this out and keeping it with my contruction log & notes. Who is Mike Shuck? >> Mike is based at Benton Airport, and we do some hanger talk at least once a week. He just completed his RV6A, and has been flying it a lot. He'll be at Oshkosh this year. Every time he sends me the stuff on airfoils, via e-mail, for some reason my computer doesn't accept the graphic stuff, and the info is very limited. Probably the settings I have, but I don't know how to alter them. I downloaded what Ken sent, but it took 19 minutes...it worked, but no graphics. I finally got to read his article. I just hope he doesn't start a trend to change the Pietenpol Airfoil. Mike is a great 'Airplane type guy', with a real sense of humor, very interested in aerodynamics (he also did an in depth analysis of the Tailwind airfoil), and has been there when I needed a hand. He has a web site on Yahoo, but you have to sign up with Yahoo to access it. The web address is: http://groups.yahoo.com/group/airfoil/files/ For his day job, he is a Doctor.

I am planning on replacing the fitting, adding a phenolic bushing in the spar and getting new hardware -- my question is whether the fittings must have the top piece welded that connects the two straps together into one piece. It would be much easier to just have two seperate pieces, one on each side of the spar and not connect them. Thanks for any input Kirk ________________________________ Message 8 _____________________________________ Time: 06:13:47 PM PST US From: "Lynn & Doris Knoll" Subject: Re: Pietenpol-List: Spar/Strut fitting --> Pietenpol-List message posted by: "Lynn & Doris Knoll" Kirk, You wanted some input so here goes. I beveled the edges of the 1 inch top piece and the two side pieces (straps) by tilting the table 45 degrees on a 1 inch belt sander. I cut 1 inch square tubing from ACE hardware into four 7 inch pieces and drilled the 1/4 inch holes for the bottom three holes and bolted the two pieces to the square tube. I put a 1/4" bolt and nut in the hole next to the top and tightened it just enough to hold the 1" top piece in place. It took a MIG welder less than10 minutes to weld the four. This is really a easy procedure and I would bet some other Piet builder even has a better procedure. Think about how much more resistance to elongated holes exists when this fitting is one piece as designed.

I have a 110hp corvair and was going to use the same as Bernie Pietenpol did on his first one that come out straight out on the sides or the one I seen at Brodhead Last original that he ran out the bottom? Any help, I know it is a personal preference. But just wanted to know if the would be a performance approvement. Thanks Dave
