Things You'll Need
Instructions
Clamp the pipe to a work bench, and file away sharp threads or burrs on both ends of the pipe. Both ends of the finished lightsaber will be covered, but exposed edges will cut you as you work.
Thread a metal sink knob onto one end of the pipe. Pick a knob that complements the overall look of the pipe and that fits well in your hand. If the knob is too big, it will throw the lightsaber off balance and make it difficult to hold.
Wrap foam rubber stripping around the center of the pipe. Spiral the stripping around the handle, taking care not to overlap the foam rubber. Add just enough foam rubber so that you can grip the handle comfortably, but not so much as to cover the entire length of the pipe.
Insert a translucent piece of plastic tubing into the top of the lightsaber handle. The tubing should be slightly smaller in diameter than the inside of the sink tube. If the tubing fits well, pull it out, coat the edge with PVC glue and then reinsert it into the pipe. If the pipe is too small, wrap a piece of weather stripping over the tube before gluing. Set the lightsaber in a sunny window to dry.
Unscrew the knob from the bottom of the handle, and slip an LED flashlight inside the handle. If you want to change the color, cut a circle of colored plastic sheet and tape it over the flashlight before insertion. Turn the light on prior to use, and screw the knob back on the handle.
