The second pole goes up easier than the first and moving one from one side of the building to the other for the top plates than back for some other task and back for another. Two was a temptation and that is the way it went. It was in the plan from the start. We stood the bents up by hand, they were planed to be raised with the gin poles, I was unsure of the number of hand available. The whole building could of gone up by hand but at more risk and grunt.
