Note: there are tons of light saber tutorials out there.

The purpose of this build is not to create a cheap light saber clone, nor a realistic looking one. The goal of this is to create the perfect combat light saber.

Goals: Create the lightest, fastest light saber which can stand up to full adult combat without breaking and without injuring anyone. Many of the light sabers I see use PVC which is heavy and can/will injury your opponent. This saber is as light as a tube of cardboard from wrapping paper. They can take a full force swing from a poly carbonate blade, and they are wicked quick.

The hilts, are designed to be comfortable, light weight and provide good grip while looking close to a "real" light saber. 

On my last birthday my awesome wife threw me a little kids style star wars birthday party. One of the fun activities she planned was a light saber battle. She bought a bunch of toy light sabers and we all drank and dueled with toy light sabers (very geeky but super fun). After the party my brother and I would occasional duel with our toy light sabers. These toys quickly broke due to their cheap plastic design. 

I looked into buying aluminum hilt, poly-carbonate replica blade light sabers on the internet. It occurred to me though, that these could break bones. The Math: (Weight of a poly-carbonate blade ~3 pounds OR 1.36078 kg [note: this is a rough estimate]) * (75 MPH tip speed OR 33.528 meters per second) = 45.6 newtons. To put that into perspective: A 45 caliber bullet weighing 12 grams or 0.012 kg would need to travel 3800 meters per second OR 8500 MPH to have the same force. I understand a bullet acts more as a needle than a blunt force object as a light saber would behave, but the point is clear, getting hit at 75 MPH (full swing for a skilled Jedi) could certainly break bone.

I started the process of building the best light saber for dueling. A saber that was light, fast, strong, repairable, that glowed.

Step 1: First version

I started by building a cheap version. PVC pipe + pipe insulation foam + duct tape = a better dueling light saber. We played with these sabers for months. We even broke a few, and inflicted serious injuries upon each other. PVC is heavy. It brings the total force of a solid blow down to about 10 newtons which is far better but not good enough. They were far better than the cheapy toy sabers though. They were strong, repairable, and worked. After a good deal of time we began getting tired of always getting injured every time we dueled. I started to think about crafting the ultimate light saber for dueling. Something strong, light, fast, and comfortable to wield.
Neat project but I'm having some trouble following the assembly instructions. Would you be able to add a little more detail around the assembly? I think that one problem I'm having is that I dead visualizing the carbon rods as solid rodes rather than tubes.. I.e. a pic or two or the parts used for the light saber itself might help clarify. <br> <br>On the other hand, it could just be a severe case of early morning caffeine depravation on my part.....
I will try to update the assembly section. Its pretty basic. I measured the volume of the hollow part of the mold, taped the end of the tube (less resin/epoxy makes for a lighter hilt), and just set it in there to dry.
