I wanted to make a really unique lightsaber. something that not everyone is even aware of. I got my inspiration from reading some of the old star wars books. there is talks of lightsabers that were made originally with separate power sources usually describing something like a pack back power source or scuba tank sort of thing .... I thought it would be kool to see a smaller power source that was located on the arm instead of the back. i feel the aesthetics of the whole thing really work well. i wanted the whole thing to feel older and used, like it has seen a few years of battle at the hand of an experienced jedi. it holds on the arm really well and is actually quite comfortable to hold onto. here are some pictures of the finished lightsaber as well as on a models arm. the whole build took a few weeks of searching for the right pieces. mostly metal parts salvaged from other things. the total weight of this saber is about 2 pounds. that weight really makes the saber feel authentic.
