Well my little brother got into Star Wars about a year and a half ago, and in the process he got me back into it; him and I like to spar so I figured one day I'd try building a lightsaber out of materials I had laying around, all I could find was a wooden dowel. Anyways I had already planted the idea in his head so I had to build whatever I could, which resulted in these:

The quality was horrible, and the hole I tapped was off centered and skewed the blade, so I made my way to home depot, bought some pvc parts and built what I could, the blades were threaded to fit the emitter, mine's on top:

The lower one in the first pic was my brother's, it had a twin that connected, but that broke after some combat, and I had to rebuild his lightsabers, this time I used an adapter instead of a threaded pommel:

Then I found Ultrasabers... specifically the metal hilts... amazing...
