I present Captain Jack Harkness's Vortex Manipulator as seen in Doctor Who and Torchwood. This was a complicated build, and I'll be presenting it in two pieces. It's a long conversation, but I think there's some worthwhile stuff in here. Throughout, I'll point out some things that worked, a few that didn't, and what we might expect from Version Two, which may be built in the future.
Any attempt on may part to list all the bits and bobs in advance would result in sadness and rampant editing, so I'll talk about stuff as it comes up. Bear with me, and let's jump in.
The first step was looking up as much info as I could to begin my build. The fine folks at SciFi Hero had a wealth of shots in addition to what I had already found. In some ways, mine is patterned after the Vortex Manipulator Toy released in the UK. Price varies wildly, and suppliers to the US and Australia have been back ordered for up to a year at a time. Plus, some folks can't even get it to fit around their wrist. All that meant I was going to have to build my own (not that I wasn't gonna anyway).
So I took the clearest photo I could find and loaded it into AutoCAD. I traced all the elements and then scaled the drawing to the size I had determined with a high-end cardboard mockup:
Happier days, shortly before I dissolved everything with an orange-scented Universal Solvent.
