After sanding primer and deburr holes I installed 1st and 2nd frame with clecos. I continued with adjust some of the reinforcement angles thet didnĀ“t fit so well. The heavier 6-B-1-53, acess step reinforcement, needed a lot of work to make them fit to bottom and side-skins as well as the heavier lower longerons. I prepared parts for the lower rudder-hingle, 6-B-1-6, -2-4, -2-10, -2-50, -2-6 and primer them. Also deburr and primer the uprights and angles 6-B-5-6 L+R, -16-3L+R, -11-1L+R and the preassembled 6-W-4.
