Thought I'd pass on what I'm using for tailwires, as it had me stumpedfora long time. I don't have enough turnbuckles and am not that keen on howthey look anyways so I came up with my own. (no doubt something similarexists in the aircraft world, or maybe I should get a patent) I used 64thou 4130 strips doubled over to make the portion which bolts to the tail. It is bent over a 1/2" rod with a 3/16" hole drilled thru the end of theportion bent over the rod. Inside this bent portion is a piece of 1/2"drill rod that has been sliced lengthwise and is 5/8" long, and is drilledthru from radius to flat with a 3/16 drill. The 3/16 stainless brace,threaded on both ends has first a jam nut, goes thru the bent bracefitting, thru the 1/2" drill rod from radius to flat and then a locknut. Makes a very clean, strong, light, and cheap fitting. They are very quickto make, and I will use them for the strut cross braces also. I tried cutting the threads, but the stainless is rather gummy, so I thinkI will try to make a jig to roll threads on my lathe. I figure it will besimilar to a pipe cutter and will traverse with the carriage like normalsingle point threading. I figure even cut threads will be fine, as theroot diameter is still a good 1/8" which is heavier than the plans call foranyways. Wayne Sippola, WinnipegPS. John McNary, I haven't forgotten your clock, just slow. ________________________________________________________________________________
