As erected this member appeared to be 3 1/2" short, due to fabrication of members, some shorter and some longer than their final geometric lengths, and due to the sub-diagonal M11 L12 (lower right). Pulled together by a 7-part auxiliary falls. Engine kept in high gear to reduce power - max. lead line pull = about 9000 [pounds], approx., giving possible capacity of 130 tons. Required one day to connect each member - two days total.
