Thats great, just what I needed.
If I don't have access to a lathe, and have no way to cut a knurl pattern on the prop hub what are my other options?
I've heard of people taking stickyback sandpaper and cutting round washers the same shape as the hub and sticking them
on there with the grit facing forward so it grips the prop.
Would this work well enough, or is that a waste of time?
Thanks DC
