SNIP Roy, At the Polyphaser seminar I attended a few years ago, it was explained that the "cone of protetction" is not really a cone. For a strike of average strength, the strike leader operates on a

Hi Dick, I know we've discussed this privately in the past. I think you are pretty close with what you have done. If the pretension doesn't allow any mast movement when you tweak a guy, the thing is

Hi Brian, ASTM A 475 lists 3/8 EHS at 15400 Lb min breaking strength. So if you are trying to get a strength equivalent look for HPTG 15400 Phillystran. They also make 20800, 27000, 35000, 42400, 583

This is good advice! What "everyone is doing" is the better choice of the available solutions. We may whine about the fact that the Rohn rotor plates only fit at one of two places in the top section.
