We quickly discovered that using the rope to pull the hoops into place was a worthless idea. It was much easier and much faster to have 5 people with sticks gently and smoothly push the hoops into place. Cody or "catcher boy" was fearless on the scaffolding and easily caught the metal hoops and set them into place. Once in place, there were a bazillion bolts and nuts to be jammed through a bazillion holes and tightened to hold the hoops togther. We made wooden supports that were jammed under the building as it was constructed to keep the center at the correct height and to keep the sides straight vertical and plumb.
