You want to start by taking all the limbs off. After that, using a razor saw or a jeweler's saw, cut the section between the upper and lower torso. You can use a dremel, but you may loose a lot of the plastic while cutting. Using a jeweler's or razor saw give you a much cleaner cut. Here you see the bottom of the upper half (the blue plastic is the bottom of the LED power supply in place). Dremel in a hole in the top of the lower half for your socket and attach the ball joint/peg to the top half. Voila! Drift has a waist!
