Finished up the W-406 and W-407 brackets. Used a thin wall socket on a universal joint to torque the nuts on the back side of the aileron spar. Used thin nose vise grips to hold the bolt head inside the brackets while tightening the nuts. Then I applied a thin stripe of orange torque seal to all the nuts and the bolt head on the front side that screws into a nutplate. Gathered parts for the W-816 and W-818 pushrods and studied plans.
