Thanks so much to everyone who voted for me in the contest, I was a second place winner!
Ah, Halloween is upon us again! I am not as consistently awesome at costumery as my brother, but I have been known to build a thing or two or three, and generally overdo it this time of year.
My friend Felicia volunteers at a small theater in Bend, Oregon. She acted in their production of Richard III, and mentioned to the director of their upcoming production of Evil Dead: The Musical that she might just know someone who could build them a new chainsaw arm to replace the one Bruce Campbell signed the last time they ran the play.
For the uninitiated, Evil Dead: The Musical is based on the movie Evil Dead 2: Dead by Dawn, which was written and directed by Sam Raimi (of Spider-Man fame), and starring Bruce Campbell (of Army of Darkness, Bubba Hotep, and Brisco County Junior fame). The movie is a masterpiece of the comedic horror subgenre, both hilarious and disturbing at times. Crucially to this instructable, there is a scene where the main character, Ash, has to cut off his own hand with a chainsaw. He later replaces his removed hand with that same chainsaw, wielding that and a sawed off shotgun to do battle with the demons he has unwittingly summoned up.
When Felicia asked if I'd be interested in building them a chainsaw arm prop, I leaped at the chance! I'd put that Dalek I've been struggling with on indefinite hold and focus my energies on making the best darn chainsaw arm I could . . . and when they asked if I could, you know, maybe make it spray blood everywhere . . . well, let's just say I stopped chanting "Exterminate! Exterminate!" and started chanting, "Swallow your soul! Swallow your soul!" After that, they even asked me to make them a Necronomicon . . . and how could I not!?
Here's a video of me acting poorly and cutting off my hand:
