Lightsabers are the preferred weapons of the Jedi and Sith alike in George Lucas' "Star Wars" saga. These swords consist of a mechanical hilt that emits an energy blade. Lightsaber hilts can be built out of parts from your local hardware and electronics stores. At it's core, it is simply a metal tube. Beyond that there are an infinite number of variations that you can create. You are limited only by your imagination and the parts that you have available.
Begin with a chrome pipe section from your local hardware store. It should be threaded on one end and measure 8 to 12 inches depending on the size of your hands.
Screw a chrome cap onto the threaded end of the pipe.
Slide several rubber O-rings down the pipe to the cap. These should match the diameter of the pipe and will serve as a grip. You can have them all pressed against each other for a solid grip, or leave some bare pipe between each.
Glue the O-rings in place with a small amount of epoxy.
Add switches, dials, lights and knobs to give your lightsaber hilt a technological appearance. The number and layout of these extra pieces is completely up to you, based on what you want your lightsaber to look like. They should be glued in place with epoxy.
You may have to drill holes in the pipe to allow the switches and other components to lay flush. Use a bit that is designed for boring through metal.
Use a centre punch to create a divot in the pipe before drilling. This will ensure that the bit stays where it is supposed to.
