My Son's finishing up a Dare Wright Flyer. It's a pusher (of course) and the props are put on backwards. The troube we're finding is the props spin off the shaft at high RPMs. We've thought about putting a little CA on the outside nut as a thread locker. Any ideas?

Thanks,
Mike

Try putting a double nut on the shaft. One nut on top of the other. Be sure you have a drive washer in place. The lock nut should solve your problem.

Ballgunner,
Thanks! Nylon lock nut looks like it's going to do the trick.

Much appreciated!

Mike
