BEEEEP BOP BOOOOP. That's my robot man telling you to make him a friend! Lay the cogs and oval on the circle blank and mark the holes. Punch the holes out and screw everything together with the bolts and nuts. It's really that simple. This project is perfect as a key chain, zipper pull or a necklace. If you wanted to embellish even more keep going with more hex bolts, or give the Riveting System a whirl.
