Expandable hub and flexible polyurethane wheels for power feeder / stock feeder

Description

Expandable hub and polyurethane power feeder wheels, 70 durometer, 1" thick, OD of 4.65" with holes cast in the wheel to make it more flexible/pliable/grippy.  I made these for the power feeder on my jointer to give more support to wider boards and to maintain more contact with a piece of wood that is uneven on the top.
