I had an interesting failure on my airplane today. I was taking a 180 pound passenger up for a ride, and about halfway through our takeoff roll, the rudder locked in place. I immediately throttled to idle and rolled to a stop. Turned out his seat had broken going over a bump, and fell directly on top of the rudder pedals, which then supported all of his weight. Could've been dangerous during a landing, as I had no rudder control.The interesting thing was the mode of failure. The seat was improperly made, the 1"x1" stringers under the seat that run from front to back on the seat bottom did not sit ON the rear support. Instead, they butted up against another 1"x1" that sat on the rear support. They should've been extended beside the rear stringer, so they would've carried the load all the way to the rear support. I hope that makes sense, if not let me know and I'll clarify.The interesting part is that the glue did not fail, the wood did in almost all joints. It even split one of the 3/4" x 1" stringers nearly in half. I've been wondering how well the glue joints maintain their strength over time in an airplane like mine. Hopefully the pictures will explain better.Pictures are here:http://www.wotelectronics.com/flying/brokenseat/Steve RuseNorman, OK________________________________________________________________________________

As a side note, I now need a very small quantity of 1/4" spruce plywood and a few feet of 1"x1" spruce stock. Where would be a good place to find such a small quantity? Should I just try to find some from a local builder?Thanks,Steve RuseNorman, OK ----- Original Message -----

MichaelI am flying a Piet with the Rotec R2800 radial. It performs very nicely and burns about 5.5gph. It weighs over 250 lbs.You will have to contact Rotec Radial Engines for price info, as the dollar has changed since I bought it and they are in Australia.Dick N. ----- Original Message -----

Subject: Pietenpol-List: Small quantities of spruce for sale- Weldwood glueSteve,Aircraft Spruce has for sale their "bargain bag" of spruce. This consists of a pretty good size bundle, many pieces 5 ft long, of all kinds of spar and cap strip cut-offs that they can't sell. I actually bought two of these along the way and I am so glad I did. I think I paid about $12.00 each for them at the time. I would highly recommend it. I made many many parts from this. Of course you have to have a way to cut and plane them to the size you need. I think Wicks has a similar bundle for sale.I'm glad to hear that the Weldwood Plastic Resin glue held so well. It is the glue that I used to hold the laminations of my prop together.Dan HelsperPoplar Grove, IL.**************Looking for simple solutions to your real-life financial challenges?

Subject: Re: Pietenpol-List: Propeller pics soonJohn,Stay tuned for the photos of my just completed prop. This for me has been without a doubt the most rewarding part of the whole project so far. Last yearat OSH I observed an old-timer (Jerry Thornhill from Hampshire IL) do a prop carving demonstration using all power tools- electric chain saw, 7 in. angle grinder w/ rubber backing pad and velcro sanding disc, and then finally a 5" DeWalt vibrating/rotary sander. This is the prop that is on the Bleriot engine that was run-up daily at Osh this year. The only hand tool I used was a metal file to knock off the high spots on the summer wood on the ash that I used.It looks very nice but now has to perform with some good thrust. The dimensions are 76 x 46 pitch. I arrived at this pitch by asking around and lookingat the archives. For those who don't know I am using a model A. Yesterday I drilled the bolt holes. Very scary but all worked out OK. Now I have to counterbore out the back side of those holes to accept the Continental-style prop hub that I bought from Ken Perkins. Very exciting times here at this Pietenpolfactory. Dan HelsperPoplar Grove, IL.**************Looking for simple solutions to your real-life financial challenges?
