The threaded stainless, even cut threads, is acceptable as that is what manyof the restoration shops use on the old biplanes. Many people do notrealize that according to an early 70s vintage article in Sport Aviationabout the MacWhyte streamline wires, they have cut threads.chris-----Original Message-----

This could be useful... I'm sure there are restrictions. Is this forstainless only? What de-rating is required? Do you have a good reference?Thanks, Gene-----Original Message-----

There is a world of difference between threaded stainless rod, which is whatI think Craig is talking about, and music wire, also called spring wirebecause it is used for exactly that, making springs. I'm not sure what kindof restoration shop would put stainless rods in wings in the place of hardwire, unless they are replacing original threaded steel rods with stainless.I'd have to see the article, because I never understood flying wires to becut threads. I've seen accidents where someone cut additional threads on awire and had it break, though.Gene----- Original Message -----

Craig:I never said you were doing anything new or different . . . I only said thatI never understood that McWhyte cut their threads. I was also trying toclear up where I believe some people on here are confusing severaldistinctly different things, namely the difference between threadedstainless rod and music wire. There is nothing wrong with anything you havedescribed here, but you don't need me to tell you that. I bet you saveseveral pounds in the tail by not using turnbuckles. I might have to givethat serious thought.________________________________________________________________________________
