Step 2Building the Base
Once you've cleaned out your container take off the lid and cut three holes in it. The one in the center is for the DC motor. The second largest hole (right) is for the Rocker Switch. You'll then cut a small hole for the Rheostat. Make sure you get a tiny slit in the lid to secure that rheostat.
Don't be worried about lining up the holes. As long as you have the motor in the center you can mess the rest up. Also, on the top of the cream cheese lid (where the label is) you might see a circle imprinted. That circle happens to be the right size for the motor.
Lastly, if you cut the hole to big the motor will slide right through. Cut the hole only big enough so the motor will fit snuggly on the lid. Use the inner diameter of the casing and not the outer diameter as your guide.
