Ash (Army of Darkness) Costume
The chainsaw was an off-the-shelf prop I hacked up a bit. The prop was actually only a couple inches thick, so I split it in half length-wise, adding some scrap boards to make it thick enough to go around my hand. I added a handle inside and a 5" (or maybe 6", I can't remember) PVC coupler to hide my wrist. A couple angle brackets and a 1" dowel rod made for the handle on top.
