I've been toying around with the idea of a fallout themed saber based around the plasma rifle and shishkebab. Unfortunately, ASP doesn't quite meet the look of fallout jury-rigged weapons, so I'm looking to the hardware store for the appropriate parts. After all, a saber made from 200 year old junk would likely be made of some old kitchen pipe or something.
So a pipe for the handle, a couple multidirectional splitters on both ends. On the pommel end, a fusion cell in one port, an air hose leading up to the top splitter (reminiscent of power armor hoses), and a pipe cap with a nuka cola bottle cap on it for the removable pommel. The top splitter has one hole taking the air hose, another has a bike brake handle mounted like the shishkebab to act as a switch, and the top hole holds the emitter. The emitter itself is a sort of cage setup, like wire cage around light bulbs, and inside is a mock plasma rifle vacuum tube made of plastic bottles. The blade goes in through the top of the metal cage frame, through the vacuum tube, and seats below to be held in by an old hose handle used as a retention screw.
I even have an idea to use the Geiger counter clicking as a blade hum sound font. And some liberty prime quotes here and there.
