Sychoclown· Creepy Clown Is Redundant
I think I rented that same video.cmwright1981: I rented a really cheesy how-to halloween DVD not too long ago. The one thing they showed that was cool was a chainsaw madman that made sparks.
I don't remember the entire setup, but basically it mimicked your Freddy idea. The chainsaw was outfitted with a replacement metal bar without a chain. There was one battery connection made to this fake bar, and the other battery connection was to a metal fence. Every time he revved up the chainsaw, he'd drag the bar across the fence and the sparks would fly. Pretty cool effect.
