Tricky rotation with linear bearings:I perfect the Video Feedback Device (youtube.com)

New anodized aluminum shafts are used with Ewellix linear bearings for much improved sliding, rotation provided by inserting the linear bearings into radial bearings (this is the tricky part!).

The wooden linear motion transfer parts are replaced with radial bearings for improved rotating and zero-dead zone when pushing and pulling the shafts back and forth. And other stuff, plus a cat and dog. Enjoy.
