Subject: Pietenpol-List: Cable brace wiresIn one of the old Buckeye News letters, Frank Pavaglia(?) wrote that hewas removing the 3/32 "X" brace wires (roll wires?) from between thefront and rear cabanes, and replacing them with 1/8 cable as the 3/32cable was stretching. ( don't ask, I'm just reporting what he said )Hansis using 1/8 there, I guess I will too. On the problem with the cabanefitting being only 3/4 behind the former, I don't recall having aproblem there. Remember that the widest part of the streamline tubewhere you will drill and put the bushing and bolt is closer to the frontof the tube than from the trailing edge of the streamline cabane struttube. this will locate the cabane farther back inside the fittings(away from that former). I'm sure thats clear as mud, but I don'tremember having a problem there. Also when I bought tubing, I wanted tobuy .032 or something like that, and no one had it, so I used .049.Since using stronger tubing I went with a smaller size. That made thatfit a lesser problem also, Also the thicker tubing made it easier toweld the bushing stock in. Leon S.________________________________________________________________________________

Subject: Re: Pietenpol-List: Cable brace wiresLeon,I have 1/8" cable in the cross brace of the lift struts (the one that attaches mid wing at about 30 degrees)I have no cables between cabanes (length wise) , but instead the tubing to the front engine mount. Spanwise cable I have 3/32"The main reason I use 1/8" between lift struts is I wanted redundancy, if all my welding failed on the lift strut I know the cable would hold the wing.Yes, I know drag wires standard 3/32 but lift struts one up.I too over engineer in places it all comes down what you feel comfortable with.It is your butt in the plane after all.Coming to that point; Today was a gorgeous day here in the Houston area, spend 2 hours in the air flying ....Flying .... My butt....ah well........Hans________________________________________________________________________________

Actually it's quite clear and your right it will push it back, so what size tubing did you use?Chris TracySacramento, Ca----- Original Message -----

William Wynne pointed out to me at EAA last summer, DO NOT put that adjustablefitting on the diagonal brace.That's what failed in his crash resulting in a ruptured fuel line, dousing himand causing severe burns He felt that if that diagonal brace was solid at bothends the wing would not have shifted forward. He also said the rest of theplane, structurally was really built tough and held up well in the crash untilir burnt to a crisp.________________________________________________________________________________Date: Mon, 27 Mar 2006 10:23:36 -0800 (PST)
