Been trying to figure out the rudder bolt access size holes. So I thought I would make a couple tools to make installing and removing the hinge bolts easier. A couple of cheap long nose pliers. Heated one with a torch and bent it for grabbing the bolt (bottom pic). The second one I welded a 11mm socket to one jaw. The 11mm is large enough for the washer to fit inside. Notched the socket, trimmed the socket and bent the pliers. Now I can hold the bolt firmly and press it down into the hole. Also can tap on the plier if needed.
