Ok, someone on this forum gave me some sage advice. Each Jedi had to build their own Lightsaber.
DOH! I didn't have to copy ANYONE! I could make my own!
So, here's how it all started. I found a camera lens in the garbage, and I'm going to apologize right away for not taking a picture of it BEFORE I took it apart. I thought I was going to fix it.
But upon dis-assembly, the inner lens was cracked.
