Ed, I borrowed the local club's Rohn gin pole and copied it. I have the annotated sketches of the tower clamp assembly somewhere; I could probably scan them for you. For the pole, I used the 2"x12'x1

Nope, I think Wendell has it right - three-point hitches usually don't have the ability to impart down force. The implements do it, usually by sheer mass or, in the case of plows, by down-vector forc
Interesting that "silver solder" is rated to a higher temp than compression fittings. Silver solder is really brazing, by definition. For instance Harris "StaySilv15" (a common "silphos" braze w/15%
Probably not. It sounds like a role of MIG wire. It has just enough copper on it to keep it from rusting when stored in a protected environment. Outside, it will rust in a month or so. Geo - n4ua Cor

When Tom says "silver solder" in this context, he means brazing. This is NOT soft solder by any stretch of the imagination. For a quick look at the temperatures involved, go to: http://www.jwharris.c
