I just finished wiring the hull of my Pygmy Osprey. I wired the keel with pliers, as suggested in the directions. Then, a friend told me to go to an airplane supply store and buy a pair of SAFETY WIRE PLIERS, which I did. These are basically locking pliers with a contraption on the end. Once you lock the pliers on the ends of a piece of wire, you pull the contraption, the pliers spin and in about 1 second your wire is tight. I'm guessing I cut the time I spent twisting wires by several hours. It was 25 very well spent dollars!
