I'm trying to create an object that acts like a rotating hammer. It should rotate at the end of the handle, be slow to go up, but then quickly come down and hit anything in the way. I tried creating two bodies, one for the handle and the other for the head, and pinning them together with a joint, but the joint acts more like a spring. If I use one body it rotates uniformly; it isn't any slower going up than going down. How should I go about this?
In the screenshot you can kind of see what I'm going for, I just want the yellow joint to have zero length.
