Evil Dead Chainsaw Arm Made From EVA Foam

A few years back, I made a whole costume for Halloween. I went as Ash Williams from the Evil Dead. I decided to make the chainsaw out of EVA foam, styrene plastic and cast resin parts. I shot video of some of the process, but unfortunately was running out of time to finish the costume, so I couldn t shoot the whole build. I would have loved to make a fullon tutorial on this.
