Riffe shaft- threaded to flopper ?

That is awesome! Genius.
I want one too!

Stole concept from a different job where we had snap on covers for protecting some bearings. It was my buddies concept, I just used it on the cover after some geometry was done. He is one of the guys that worked on that Titanic model I posted a while ago.
