I was lucky enough to have the electric motor already mounted to something usable, so we'll forget it for now. To start with, I drilled four evenly spaced (eyeballed) holes in the peanut butter jar on the neck of the bottle. I then cut four notches in the DVD case to correspond. Not too deep, just enough you can hang a piece of wire over the edge without interfering with attaching the base again. I then ran some wire through the holes and hung the peanut butter jar inside the upside down DVD case. Finally, I used a hacksaw to cut off the threading from the spindle so I could glue the gear directly to it.
