Could you send more detailed pictures, videos, technical drawings on how to use the smaller turntable bearing kit? The video you have posted on the vex Website is confusing. In the video it shows that you have removed the back cover plate of the bearing in order to mount the c-channel arm. The cover plate is what keeps the grease inside the beating such that if you take it off like you’ve shown in the video! The grease is allowed to drop out and also the three components to the bearing are allowed to disconnect from one another - these are the gear ring, internal rotating turntable and the circular plate between the ring gear and turntable. I’m trying to use the small turntable bearing kit to built a wrist that can totate freely 360 degrees.
