How-To: Rotary Bench Cams:
Clever, simple idea for a workholder that grabs automatically when you push a board into it, and releases automatically when you pull it out. From medicinal chemist and woodworker Brian Grella. From where I sit, it looks like you might only need to make one of these rotating cams, and the other side of the clamp could be a fixed, flat fence. [via Instructables]
