Just weld a standard 3/8" Hex nut to a small steel plate, drill several holes in the plate, drill a 3/8" hole in the lower main spar at the desired location, push a waxed 3/8" eye bolt into the hole and screw into the "Hex nut" , epoxy with flox the "Hex nut and plate in place. After the epoxy dries, remove the eye bolt and reinsert whenever you want. ----- Original Message ----- From: "Jim Morehead" To: "KR- Net" Sent: Sunday, July 06, 2003 11:31 PM Subject: KR>Tie Down Attach Points > Netters, > > What kind of tie down attach fittings are you all using using on the wings? > I have been trying to come up with a flush pull down or swing out ring to > attach a tie down rope. > > Thanks, > Jim Morehead > Cameron Park, CA > Cut out the Ailerons, glassed in the aileron spars and attached aileron > counter balance. > Looking forward to Red Oak. > > > _______________________________________________ > see KRnet list details at http://www.krnet.org/instructions.html > > ------------------------------ Date: Tue, 8 Jul 2003 23:08:00 -0700 From: "Charles Buddy & Cheryl Midkiff" To: "KR builders and pilots" Subject: Re: KR>KR for sale Message-ID: <016001c345e0$7357ca70$0d02a8c0@charlesmidkiff> References: <20030706162618.91370.qmail@web21201.mail.yahoo.com> Content-Type: text/plain; charset="iso-8859-1" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Precedence: list Message: 16 I saw another KR-2 for sale in the July 4th edition of the General Aviation News which I just received today.

Heath - Columbia, SC +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++= Dan, What are you riveting the blind nuts to, the 1/4" spruce? If so, what is the technique for using a rivet in wood? The plans call for the nut plates to be floxed to both 1/4" aileron spars (wing and aileron). I'd suggest you run the 8-32 bolt in and out several times after the flox cures to insure the threads are clear of any epoxy and that the flox will hold. A quick test is easier than opening the wing or aileron to repair.

Grain orientation really doesn't have to do with how the spar will fail or crack. Grain orientation has to do with how the shape of the spar might change as the wood gains or loses moisture. If the grain is not straight and orthogonal to the spar axes, the spar could bow, cup, or otherwise deform. The orientation and tightness of the grain, as well as the clarity of the wood, is of great concern for uniform strength of the spar. As a starter, get (and study) the EAA "Wood Book" (EAA Aircraft Building Techniques- Wood; $11.95) for much more detail on selection and grading of wood for homebuilts. And remember that the spars, more than any other structural piece in the airframe, are what holds your present and future together. >Can duglas be used for the spars? Douglas fir, properly graded and applied, can certainly be used for your spars. It costs less than spruce, is stronger than spruce, but weighs more. Again, refer to the "Wood Book" for more detail on comparisons between commonly available materials.

Take a look at the pressure distribution diagram (sketch) about halfway down the page at http://home.hiwaay.net/~langford/cowling.html to confirm what you've found. This will vary with a lot of things, but you may be surprised to find that the pressure around your cowling isn't always as you'd expect.

You might be interested in the following story from John Dilatush of Salida, Colorado. John has a beautiful Pietenpol with a turbo'd Subaru EA-82 and manual wastegate control and flies it out of his home airfield which is at about 8,000 MSL: ================== I went to the Rocky Mountain Regional Fly In this past weekend. Because I was sequenced too closely behind another plane on approach, I made the decision to go around. Due to my own stupidity, when I added full throttle I failed to open the wastegate of the turbo and the engine overboosted. The effect of the overboost was also increased because of the lower elevation of the airport, 5,000' vs 8,000'. As a result, the engine probably produced 500 hp for about 5 seconds before it blew coolant all over the place. I was able to swing around and land safely on the little ultralite strip. After landing, it only appeared the damage had been limited to blowing the exhaust crossover pipe, so on Monday, I rented a car and chased parts in Denver. Tuesday I installed the pipe and decided to fly it again. This time the engine really blew up blowing coolant and oil all over the place. This time I couldn't make a runway, so put it down in a field next to the airport, landing diagonally to the furrows which gave me a little longer length between the fence at one end and the ditch at the other end. Those big old wheels are sure great for off field landings! No damage to the airframe, just a big hole in the crankcase of the engine. A friend flew over from Buena Vista in his RV-4 yesterday and picked me up. So now the plane is sitting in a hangar over there, dripping oil and coolant and waiting for a new engine. I'll tell you Oscar, there is no thrill like having to cope with an emergency landing with coolant blowing all over the windshield and your goggles and having to pee at the same time! ======================== >From my limited time flying anything with a turbo, I know that it's just one more thing to attend to when you're busy in takeoff mode... gotta watch the top of the green when you throttle up, and you have to nurse it along as you climb. Again, just one more thing to watch. Oh, and if anyone is interested, there are pictures of John's Piet (prior to the accident) at http://www.flysquirrel.net/piets/John_piet.html Oscar Zuniga San Antonio, TX mailto: taildrags@hotmail.com website at http://www.flysquirrel.net _________________________________________________________________ STOP MORE SPAM with the new MSN 8 and get 2 months FREE* http://join.msn.com/?page=features/junkmail ------------------------------ _______________________________________________ See KRnet list details at http://www.krnet.org/instructions.html End of KRnet Digest, Vol 91, Issue 1 ************************************
