I'm putting up a 50' Rohn 25 tower. The tower is anchored in concrete at the base (36" dia X 5' deep with rebar) and braced with a house bracket at 10' above ground. This tower replaces a 40' crank-u
Hi Bill Right now 1 of the guys on my crank-up tower is hooked to the base of a big fir tree. One thing you have to be real careful about is to make sure the eyebolt, or whatever you use to hook to t
I thought I remembered reading somewhere that wrapping the guy around the tree, lining it with old garden hose, and clamping it was one method. Since we are supposed to check our systems at least onc

I'm not sure that backing the nut off is required. In 1972, I drilled a hole through a 12" maple tree, and installed a forged eye bolt with a large flat washer and nut on the other side. Three-hole e
