Hello Piet Builders and Fliers I am one of those guys that have been on the list for a year now andon the side lines. Most questions by following the discussions have beenanswered. And by going to the archives I have been able to answer otherquestions I have had you fliers once builders have asked. I am going toget into the egg money and buy the turnbuckles, shackles, shackle pinsand cable thimbles I need for this project. I am going to use 3/32 cableon the tail brace wires ,elevator control, aileron control and cabincross braces. I will use 1/8 cable on the rudder, wing drag and antidrag wires, strut bracing and joy stick to walking beam. Looks like Ineed 20ea AN 130 -16S and 14ea AN 130-22S and 1 AN135-16S. Theseturnbuckles have a cable eye on one end and a fork on the other. Doesthis sound like the turnbuckles that most of you have used? I am goingto buy them from A&S account they give a 10% or 15% discount if one buys10 or more of one item. Just as a note I have the Fuselage on the cub style gear, tailassembly, Wynn Corvair engine mount, 3 piece wing center section with 13gallon fiberglass fuel tank constructed. The wings, engine and cowlingare left to do. I have been at it part time for two years and 3 monthsnow with 40% done and as you all know 98% to go.Thanks AllGary BellDelaware, Ohio________________________________________________________________________________

Hi Gary,I've never actually counted the turnbuckles (scared to know exactly how muchI've got invested in them) but your numbers sound about right. I used onlyAN130-16S and AN130-8S, no -22's. 7x19 stainless 1/8" cable has a breakingstrength of 1760 lbs. And the -16's are rated at 1600 lbs., but that ratingis with three threads exposed on each side (maximum allowable) As long asyou have less than three threads exposed, they should be stronger than that,and will be approximately as strong as the cable (and lighter and cheaperthan the -22's).Why use 1/8" cable on the rudder? The plans call for 3/32" and it is morethan adeguate, with a 920 lb. Breaking strength (I guarentee you the rudderwon't withstand a 920 lb. Load) and 1/8" cable weighs nearly twice as muchas 3/32" (.029 lb/ft vs .0174 lb/ft., assuming both are 7x19). Withapproximately 25 feet of rudder cable, the weight penalty for 1/8" would beover a quarter of a pound, with a large moment arm from the CG. Rememberthe quote from Bill Stout that someone on this list is fond of quoting:"Simplicate and add Lightness".Good luck,Jack Phillips -----Original Message-----
