Long time lurker here. Now, these are not nearly as impressive as everybody else in this thread's efforts, but I have a reason for sharing now that I will get to in a moment.
These lightsabers are, from left to right, my first three attempts at creating
my lightsaber (beyond cardboard toilet roll tubes with drawn on buttons, but I'm choosing not to count those).
The one on the left is a PVC pipe with a cardboard shroud and pommel covered in aluminium tape, hit with matte black spray paint and weathered back with steel wool, the only other hardware it uses are a few screws from my old, broken typewriter, and the emitter, which I'm fairly sure I ripped out of an old electric razor. I'm okay with this one for a first try.
The one in the centre is my foray into my Dad's box of random plumbing bits... Yeah, I don't like to talk about that one. The emitter is nice, but the rest just pains me to look at.
The one on the right began it's life as a silver plated marriage certificate holder (a first for this thread, if I'm not mistaken) that my Dad and I stripped back and did some light machining on his lathe, added a button too, weighted with two pence pieces, and created an emitter from a short piece of copper pipe jammed into the end with a plastic spacer. This final one I like aside from a few things. It's still too clean, it doesn't feel like any of the original lightsabers to me. It's more akin to the prequels, it's got a much smaller diameter and it's way too ornamental and doesn't feel like a tool.
Thankfully, my next project is already leagues ahead of these three, for we managed to snag this on Ebay today.
I'm excited, not gonna lie.
