- Build the most detailed Homura's Time Shield from Puella Magi Madoka Magica out of freakin' Magic: the Gathering cards. Since no one else builds with MtG cards, I'm already a winner. Hooray for shallow goals.
- Make the gold shutter covers for the sides open. Not "removable" where you pop them off and lose them during a convention. They must open and retract into the shield.
- Add loose sand. No cheating with painting the sand containers red. The sand containers must be spheres and cannot be cheap jello cups or colored gems.
Planning and Research
There's two principles of building this shield: Aesthetically or Accurately. Aesthetically being that with exception of the center gearbox, the shield's features are symmetrical. Accurately being the result of my research into the actual shield itself: as close to the anime concept/production art as possible. Interestingly, you cannot have both.
Compasses are useless. The compass lead is blunt and imprecise. It's easier to draw a circle by making two holes on a strip of paper (equaling the radius), pinning one end to the center, putting a pencil on the other hole, then looping around. It's also reliable since you don't need to adjust the compass each time for repeated passes. So much for buying a compass.
Building gears teeth-by-teeth by gluing each tooth equally spaced around a cylinder is tedious. Given the alternative of cutting each tooth around a circle, gluing teeth one-by-one is easier. Screw building gears ever again. At least they're decorative and don't need to bear loads.
My plans focused on making the shield shutters open using gears. Worst idea ever. I do not want to cut gear teeth by hand with a knife. Archimedes did it, but I sure as hell don't want to. Did I abandon the effort to make the shutters open? Nope! After some math, I determined the dimensions to get a four bar linkage going that would open both shutter halves with a small 30 degree turn.
Currently, here's where I'm at. The outer ridges were difficult to judge the height of, since the line art and screencaps don't give much depth about any features. I'll consider releasing plans if someone really wants them.
More progress whenever it comes. Let's hope I succeed. 50 sheep tokens are resting on this.
