Whats a good ratio for the pulley on the motor to the pulley connecting to the spinner weapon? The spinner is for an ant and is about 2.5 inches in diameter and weight about an ounce.

The ratio depends on the motor and how fast you want the weapon to spin. Calculate the top speed of your motor by multiplying the motors kv by the voltage you run it at then gear weapon up or down to get to your desired speed. I have no reference for desired speed in an ant all my experience is in 15 pounders.
