The Speedy® Prop Rod - PR-1 is a 5” long Prop Rod made from an accurately machined rod of aircraft grade aluminum that is precision threaded on both ends to 6mm on a $150,000 CNC lathe to a tolerance of .0005” (1/2 thousandths!) On the CNC lathe the rod is held in place with a friction collet to protect the extra smooth surface of the rod so it can roll freely for precision balancing.
The Prop Rod is designed for use specifically on the Speedy® Prop Balancer but can also be used on other balancing devices such as the DU-BRO brand and others.
