[UK-CONTEST] Gin Pole Pulley system

[G3SJJ]

Thanks Colin. Mine is similar to Stewart's, maybe a bit neater but then 
I have more time available! It was how the rope is strung between the 2 
double pulleys I was interested in to get maximum mechanical advantage. 
I will be using 3 x 20ft scaffold poles plus a narrower 10ft spole out 
of the top section to make up 70ft. I have done it in the past but 
recently felt I wasn't getting the best efficiency as it was hard going. 
OK, or maybe getting a bit old to be hauling up 70ft gin pole masts in 
winter!

I got a 70ft mast up a few weeks ago back but it wasn't very well 
engineered and fell down in the wind last week. I have completely 
re-engineered it and now looking at the hauling mechanism. This one has 
to stay up!

Thanks again. Chris
