This prop duplicator is based on the plans from Copy Carver. The size of the duplicator was increased slightly to handle lift fans up to 34" and 72" props.

The duplicator is complete and working. Here is a 1 minute video, 2.7mb, of the duplicator in action. It is cutting a prop for a 10F. It is not the quickest, but it does work. Using a chainsaw or bandsaw to remove the excess would speed the process along.
