Pietenpol-List: cable fabrication

Post by matronics »

Original Posted By: "Gene Rambo"
I am needing to make the four brace wires for the wood landing gear. Any suggestions on how much to screw in the turnbuckle when I measure the length needed? Any idea of the amount of stretch to expect with 1/8"-inch cable. Basically the question is, approximately how much shorter then the measured distance do I make the cable. I know about the three threads out and four in specification for turnbuckles. Or is it just a wasteful trial and error type thing.ThanksChris TracySacramento, CaWebsite at http://www.Westcoastpiet.com ________________________________________________________________________________

no threads showing. There is no stretch and you'll be surprised how much slack comes out with a little tightening.Gene ----- Original Message -----

Chris,For what it is worth, when I was making up my new drag wires I allowed half the threads on the turnbuckle to show when making up the cable. Once made, I screwed the turn buckle in until no threads showed and the tension seemed just right. One neat little trick that worked well for me was before I swaged the nicopress sleeves I placed a electrican's 1/8" wire saddle (not sure if that is the right name or not but it is what electricans use to attach one wire along side of another. It is in the shape of a U with a nut that screws down forcing a wedge that holds the wire to the bottom of the U). They can be bought at any electrical supply store. I put the nicopress sleeve on and put the wire saddle on behind it and tightened it down. It would hold the wire in place while I tightened the turnbuckle to check to see if it would be the right length. Once I was happy with the length, it held the sleeve while I nicopressed it. Sorry if all that is as clear as mud.Gene________________________________________________________________________________
