Easter Egg Anemometer (Wind Speed Meter)

Step 2 Rotor Assembly

Use a hole saw to cut a little wood disc for the rotor assembly; predrill the screw locations. Find a good location on the eggs halves and drill the 3" screw through it from the inside of the egg. Hand screw the screws into the wood disc. Balance can be adjusted by adjusting the screws. Mount the rotor assembly onto the motor; you may have to drill the center hold in the wood a little bigger to fit onto the plastic gear. Super glue wood to plastic.
