| Subject: | reinforcing for: cabane and jury struts |
I added carbon fiber to my laminated mahoghany/spruce cabanes (WAY
overkill!). 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.

My lift, cabanes and jury struts are wood. 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 am sure no expert on carbon fiber or any other method of fabric re-inforcment-but
does the stuff really give much added strength if you cannot pre-tension
it when you lay it up? I don't know-that's why I'm asking.Raymond

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

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............
Paul
