I'd appreciate advice on selecting rope to guy my 90' irrigation pipe
vertical.
I use four guys every 15' on the pipe.
In doing rope research I find these given:
uv resistant double weave dacron
double braid polyester with black uv, mildew, abrasion resistant jacket
uv resistant dacron
kevlar/dacron
Also available is 3/16" Phillystran. More expensive than dacron rope; has
enough strength for my application; and estimated life of at least 20 years.
At my age (78) the estimated life of rope has been given at 10 years which
may be enough!
For strength comparisions, and using a ratio of 1 to 6 for working vs
breaking strength, I find these numbers for ropes:
3/16" uv resistant dacron 385#
3/16" double weave dacron 128#
3/16" Phillystran 200#
>075" kevlar/dacron 100#
What would you choose and why? Are there other factors to consider other
than price (except for Phillystran probably not a big factor); ease of using;
life expectancy, etc??
73 Bob W7LR in Montana. Wind and ice are not bad here but cold winter
temperatures are. Abrasion is not a problem. Humidity is very low. Moose,
deer and bears could be a problem for any rope.
Thanks for your help and advice.
