I know Rans aircraft used some tabs that had staggered holes for the bolt and Nicothe cable through the other end hole. gives you some take-up adjustment andyou can put a few extra twists in the cable to get just a little more. -I wouldn'twant to un-twist it.RaymondRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Mon, 3 Aug 2009 20:04:10 -0400

Twist the wire to lengthen or shorten it.I made up the bottom braces tight enough to have to pulldown a little on the stab to put in the clevis pins on bothsides. Then supported the entire tail on 2X4's just outsidethe stab fittings. This tensions the bottom cables. I tied amilk bottle container to the tail and filled it with bricksfor more tension. The upper cables were already nico'dto the rudder so I ran them to their respective places onthe stab, set up all the bits, pulled everything tight andclamped with those U bolt cable clamps. At this pointI ran around tweaking the tension and making absolutelysure the rudder fin was 90 and straight, the two endsof the stab were absolutely level with each other usingwynding sticks and then proceeded to do up the nico's,checking everything after each crimp.The wynding stick method, ancient as it is, is accurateto more than a hundredth of a degree. With a good eyeeven closer.All you need are two straight, square sticks or tubes,one white, the other black. The longer the better.ClifWynding sticks, kinda like the way they built the SR-71.Subject: Pietenpol-List: Re: Tensioning cables without turnbuckles> Tim; I haven't tried this idea as yet but here it is for your information.>make up the other ends as tight as possible, remove the washers, tighten, and all should be tight.
