I am building a cantilever support for a manual winch to raise a 24 foot vertical antenna weighing 40 pounds. I plan to mount the winch on the end of a
24 inch section of 1 inch cast iron pipe and am concerned about the pipe failing. The non winch end will be attached to a Tee cast iron fitting with the support pipe ground mounted in concrete [sort of an inverted 'L'].Any comments or ideas appreciated.
