96,
Sorry for the wait ... The "pin method" takes small pieces of pieces of paperclips, straight pins, wire ... whatever you want to use. Drill a small hole, in the case of attaching an arm, in the torso where the arm connects. Then, take a fine point sharpie, and draw a cross/ plus sign where the arm will connect with the hole being where the cross crosses itself. Then take the arm and place it on the torso in the position that you want it. Then take the sharpie again and make small dots on the arm where you see the lines coming on that you drew on the torso. Take the arm off and then connect the dots, making another cross on the arm this time. Drill the hole in the arm where the cross crosses itself. Now take your pin, I usually cut it after I glue it to one side ... after it dries of course. Glue in one side, then mount the arm with a little glue and BAM! ... your done.
Sounds like a long process, but it is really pretty quick and will definately strengthen you figure. I do this on ALL connections for my figures. Feet, legs, torso, arms, head ... everything.
Hope this helps.
