It’s always better to do the right thing and get a good prop. However, depending on your mechanical skills and cleverness, it is sometimes possible to lock the hub and outer prop together by mechanical means, meaning screws, basically. It’s cheating, it’s often ugly but it works in a pinch. There are horrible ways and more elegant ways to do this. It is up to the person doing it, just how to do it; using a combination of mechanics and "art." If the prop with the spun hub is useless anyway, being unrepairable by proper means, then what’s a guy got to loose?
Long live American manufacturing!
