A couple of friends of mine are going to an anime convention in Atlanta this weekend, and were wanting to do some steampunkish cosplay. They were looking to have some props and pieces for their costumes, so I obliged and made up a new ray gun.
The construction is pretty obvious, I pretty much just took a look in my junk bin and pulled out anything with a neat coil or old looking electromechanical component. I wound up soldering a copper pipe to the shaft of a vacuum motor core. Then, using pipe clamps I mounted that to a pull saw handle. I attached the other bits with super-glue, some more soldering, hot glue, and adding magnet wire where it looked necessary and what you see below is what I wound up with.
It's pretty hefty since it's got so much steel and copper to it. I was originally going for steampunk, but since I didn't have much copper or brass on hand, but did have plenty of coils and simple but chunky electronics on hand I went with that and I've decided to further splinter the "old looking things that look like more modern things made with old technology" movement and dub this a Teslapunk death ray. It's not quite Buck Rogers looking enough to my eye to group it with that time, and the round motor core on top kinda looks reminicent of a revolver. My original plan was to have there be a button and battery to trigger the solenoid so there'd be some motion to it, but since they were headed out I decided to put further additions off for the moment. Maybe I'll add that and some sound effects when they get back.
