Decided not to do the lift struts in wood because of the weight, but there are several Piets flying out there using wood struts with and without reinforcing laid into a routed center area. Sure looks good. Anyway, for those of you that are using laminated wood for cabanes or struts, I have PLENTY of carbon fiber left over. Probably enough to laminate struts for 100 Piets! I've attached a picture of how I laid the carbon fiber in between the laminations. Other materials, like Kevlar, are probably better in tension than carbon fiber but it added no noticable thickness to the lamination and had to help reinforce the bolt areas. You can just barely see it in the lamination. In fact, after vacuum bagging the whole thing you couldn't even tell the carbon was there until sanding those areas and finding a tiny black area between the laminations. Mostly I figure it probably strenghtened up the bolt hole area to help avoid splitting. So if anyone wants to do the same, contact me OFF LIST (jim_markle@mindspring.com) and I'll send you enough material to do your lift struts and cabanes.

They're a sandwich; spruce-1/4 ply-spruce. I don't recall the exact thickness, but they're copied from Alan Wise's who's flown hundreds and hundreds of hours with his. I believe the only metal he used was steel strap sandwiched in the jury struts, which is what I did. Won't do anything in compression, but will be helpful in tension. Just tracked down a guy up north who's piet I noticed had wooden struts in an old back issue of the newsletter. Finally talked to him and he's done the same thing with no problems whatsoever. I know Gary (now Keri-Ann) Price's used wood struts, but they DID have square tubing inside, so the wood was really cosmetic. I like your idea of hiding the lines etc inside the cabanes. Rather than bulking it up further, why don't you rout a channel and epoxy a thin walled steel tube in there to act as a conduit? The tube would more than make up for the material routed out. I'll send you a picture of my struts offline since I still can't figure out how to send or view photos.

I don't know-that's why I'm asking.Raymond Read this topic online here: http://forums.matronics.com/viewtopic.php?p=236309#236309 ________________________________ Message 6 _____________________________________ Time: 08:39:00 PM PST US From: shad bell Subject: Pietenpol-List: Finding Flight Group, I ________________________________ Message 7 _____________________________________ Time: 08:47:48 PM PST US From: shad bell Subject: Pietenpol-List: Findng Flight Group, After watching the Finding Flight DVD I bought at brodhead last year I can't wait fot July!- I got a little done on my Jungster tonight, afte r watching my 3 month old all day.- Any suggestions on how to get airplan e building done and watch a newborn at the same time?- He is OK in the sh op as long as it's warm, and I don't have the belt/disk sander blowing dust in to the air.- I figure I might has well start him young, hell who know s if his generation might be the last to be able to build there own airplan e.- Hopefully Jacob will learn to fly in the piet, then beg me to fly my Jungster or the Cassutt on his 16th B-day.- Any ways, I am looking forwar d to flying to Brodhead and Oshkosh this year for the 80th ann. of the Piet .- I hope to be able to join up with a few Ohio/ mid west piets enroute t o Brodhead and fly up togeather.- And by the way; Can someone tell me whe n the Winchester Indiana Hay Field fly in is?- I want to try to get the time off work to attend. - Anxious and ready to fly, Shad=0A=0A=0A ________________________________ Message 8 _____________________________________ Time: 08:47:48 PM PST US From: shad bell Subject: Pietenpol-List: Findng Flight Group, After watching the Finding Flight DVD I bought at brodhead last year I can't wait fot July!- I got a little done on my Jungster tonight, afte r watching my 3 month old all day.- Any suggestions on how to get airplan e building done and watch a newborn at the same time?- He is OK in the sh op as long as it's warm, and I don't have the belt/disk sander blowing dust in to the air.- I figure I might has well start him young, hell who know s if his generation might be the last to be able to build there own airplan e.- Hopefully Jacob will learn to fly in the piet, then beg me to fly my Jungster or the Cassutt on his 16th B-day.- Any ways, I am looking forwar d to flying to Brodhead and Oshkosh this year for the 80th ann. of the Piet .- I hope to be able to join up with a few Ohio/ mid west piets enroute t o Brodhead and fly up togeather.- And by the way; Can someone tell me whe n the Winchester Indiana Hay Field fly in is?- I want to try to get the time off work to attend. - Anxious and ready to fly, Shad=0A=0A=0A ________________________________ Message 9 _____________________________________ Time: 10:45:25 PM PST US Subject: Pietenpol-List: Re: Findng Flight From: "Paul N. Peckham" Shad, I know the feeling of trying to find time to build. I don't have an answer, but I do have a story. When one of my boys was about 3, he was out in the shop with me, was getting a little tired, so he climbed up on the workbench and promptly fell asleep. Didn't get much done after that, but it was definitely one of those Kodak moments............
