retro posting: raising the first rib
We lifted the rib to an angle so it would not just pull flat along the ground. Once we tipped the rib we placed blocks behind it so it would not slide.
All set. Rope attached to truck, Truck in gear, pulling forward. As we moved the truck forward the pine bent lower and lower. I thought the plan had failed. I parked the truck where it was and when I went to examine the situation I discovered that the rib now felt like a 2x4. It was essentially spring loaded by the bent tree. Allowing the spring of the tree to do the work we simply positioned the rib where we wanted it and lifted the holding blocks out of the way. We nailed some angled boards to the rib to keep it from tipping and the first rib was in place.
