I made 6 pieces of plastic that are 5 * 3 and I used them for the base for the hammer. I used a laser cutter but anything that can cut through plastic will work. I used pieces of plastic that were a 1/4 of an inch. I then wrapped them in duck tape to keep them together. I then put 16 washers on each long side of the head and wrapped them in more duck tape. Then I put 8 washers on the Side I wanted to use to hammer and wrapped in more duck tape to hold in place.
Step 2: Step 2 Attaching It to the Stick
