So you have decided to take the final step to embracing the force. Does your path follow the Light or the Dark side? (I hear the dark side has cookies).
What ever side you are on, what follows is how to make a Duel-Worthy Lightsabre. That means, you should be able to wield this sword and bash it against things and other lightsabers with little fear of actually breaking the lightsaber. You may end up breaking other things, but the lightsaber will remain intact.*
Total cost of this project is $60 to $1,000 USD. The wide range in cost all depends of how crazy you get with your design. The cost of lightsaber I built for this instructable is about $160.
