A Round Trash Can
A Old Electric String Trimmer (gas if you're really good at mods)
Some Scrap wood 1x2s
.25" Hardware Cloth
1" Deck Screws or Similar Screw
Note: One picture below shows the machine upside-down; snap off the screw ends with some pliers.
Step 1: Cut Holes in Trash Can
Mark and cut the holes for the trimmer shaft (actually this center hole becomes a lot bigger later on so the head spins freely)
Mark and cut holes for your hardware cloth screen. Leave enough metal/plastic to support the motor.
