I used an old bike helmet for the dome (skateboard style) and used WOF's templates for the rest of the helm. It didn't take much work at all. I used plastic license plates, glued and stacked for the "ear and stalk" areas, then sanded them down. I also used plastic license plates to work the rear vent area of the helm. the sides of the helm were made of matting board, (about $7 at hobby lobby for a large sheet) and I actually went with 3 colors of board, just to see the details before I fixed and painted the helm. I then fiberglassed the inside (only cost about ($10 for auto fiberglass resin at wal-mart) and then I bondo'd the outside (especially important when covering the vents in the old bike helmet{btw, take the foam out of the helm}). I then painted!!! Only mistake I made was to use a thin piece of plexiglass for the visor. I tinted it first then installed it but I cracked it when installing. Luckily the tint covered the crack and it still looks cool. All in all, it took me about 30 minutes a day for about 10 days to get it complete!! and it held up great for trooping around for 6 hours on Halloween. My next project is to get a small fan in there to avoid the visor steaming up, and maybe make an earphone port to listen to some tunes when I'm bored and trying to avoid the wife!!!
