Great Planes 4-Step Standard Prop Shaft ReamerTower Stock# LXK248 • Manufacturer Stock# GPMQ5005
Notes from our tech department:
This is NOT for metric shafts. It is used to enlarge the hole on the prop
because most of the time the hole is too small to fit the engine. This is the
best way to do it because it will not split the prop and will keep the hole
It will ream holes with a diameter of 3/16", 1/4", 5/16", and 3/8".
