After seeing the Swinging Sicks Kinetic Energy Sculpture on Ironman 2, I thought it would make a decent clock.
Tools used: drill, saw, tap, scissors, and a round file, nails. W/ a few other as you can tell.
Materials: Quartz clock movement, 5"X6" wood plaque, Wood sticks 1/2"X1/8"X2', wood dowel 1/2" round X5/8" long, non-insulated connectors, rubber band.
I got the measurements for the sticks from: bloomautomatic instructable
I cut sticks and dowel to length, Drilled holes for hour hand movement to a small piece of stick with dowel nailed to small stick and hour hand. Used connectors for my pivot points with a piece of nail though hour hand to act as an axle(needed to keep it from twisting due to rubber band I used as the belt made it twist out of shape.
