Thanks for the info. My fan has a small imbalance and the thin struts let the cage vibrate. 

On a Dubro prop balancer, the blade has a heavy side. The hub where the blade rivets on is .010 thicker. I’m not sure if this is the issue. I filed some metal (.04”) off the outer edge of the heavy blade. This helped some. Maybe I need to take off more to balance it. The blade alignment is spot on.
