Here's how I rolled the leading edges of the rudder. For starters, I used wooden dowels inplace of the steel pipe I used to do the elevators. The steel pipe got chewed up by the pliers and were a hazzard to my hands and to the aluminum skins. The wooden dowels also get chewed up by the pliers but don't damage the skins - but you can get splinters!
