Prop Balancer for Wooden Propellers

Prop Balancer

Wooden props need to be drilled. It's best to use a bench/pillar drill to ensure the hole is at right angles to the prop. A hand drill can be used with care. Enlarge the hole in small increments (0.5mm is best). Drill half way through, then turn the prop over and drill through from this side. Repeat this until you have the required size. Make sure the prop is restrained when drilling so that the prop can not rotate and injure you.
To balance wooden props spray clear car lacquer on the lighter side so that it is slightly heavier. When the propellants in the lacquer evaporates off it should balance horizontally. Check the balance again when the lacquer is dry and repeat the above if necessary.
