[TowerTalk] GENPOLE PULLEY

[AD5VJ Bob]

Hi Roger and all

Thanks 

This one was a pot metal one, you can see the seam on the sides, so I guess I can be glad I had the idea of trying it on a little
above ground level before going up with it. It wouldn't even raise it off of the ground.

One thing I didn't have was the pulley at the bottom and it was pulling at an angle. From what I have read on the website sent to me
it can not be at an angle to pull and it needs to be close to the tower as possible. None of those conditions were met either.

Guess there is more to it than I had thought.
