Just purchased this Double Pulley Wood Block and Tackle for 3/4 inch rope to help with lifting during the assembly process. Got it for about $80 with shipping which is a whole lot less than a new set. Now I have to pick out a nice straight pine that I can gert and peel to use for a gin pole. I have never used one so thanks to the internet I should be able to figure it out. Here is pretty good website that explains the setup and safety. I figure a bent will weight just under 1,000 lbs. so with a couple of strong backs and a pulley at the bottom of the gin pole to redirect the pull and hooked to a tractor, the bents should be pretty easy to upright once assembled.

Another really good site that describes the construction of a similar shed as mine is:

Although my maximum beam length by design is 12', I believe that it will still be beneficial for me to use a gin pole if I can figure out how to do it effeciently and safely. I still need to find me a single redirecting block for a 3/4" rope.
