We made this for a couple of blue screen visual special effects shots done on a stage at Universal Studios in Hollywood.
They found that it was easier, safer and cheaper to contract a scale model that to get helicopter shots of a storm sequence 8 stories off the ground on its actual location in upstate New York. Typically miniatures are used for obvious effects like Sci Fi space ships etc, but when done right they could just be everyday shots in a film that blend seamlessly as a cost savings to the overall production.
They needed the interior to be fully functioning, so I made the rotating reflectors from 4 'mini-Maglights' with the really powerful focused beam. I had to cut part of each of the 4 reflectors to fit inside the miniature bezel. There is a 5th bulb on top to light the inner cap of the bezel. Its all made of plexiglas, cut for the ribbed effect, then layered with gold & silver reflective tape.
I made the frame that housed the gears out of 1/8" plexiglas, the gears & variable speed motor are from RC race cars. I soldered wires inside brass rings that are then 'hugged' with ladies hair clips, as a way of transferring the low voltage power to the mag lights above. Otherwise the wires would have twisted into a knot after a few rotations of the bezel above.
