> In the massive storm of April 1, 1997, the third largest snowfall in the
> history of the Boston area, I lost backstays on three TH6/TH7's. Two on
> one tower, and one on another.
>
> Examination shows that the backstay wire had rusted through. The plated
> u-bolts and saddles were also heading for the "rust to dust" stage of
> life.
>
> I am now contemplating a trip to Bliss Marine, to buy 1/8" stainless
> steel guy wire. This marine supplier also has a $20 device which uses a
> socket wrench to tighten small nico-press style holders (for about 48
> cents each) to hold the backstays in place. The big crimping tool is
> $120.
>
> On the other hand, K1LZ is recommending that I use wire rope in a plastic
> cover, with 54 cent plated u-bolts and saddles (small ones).
>
> I recall that W1RR, a smart person in my judgment, has used dacron rope
> for backstays, as well as Phillystran (on BIG booms).
>
> The project is: backstays for a 24' boom TH67/TH7. What would you
> recommend?
