Re: The afterthought bridge manipulator
An easy way to make one of these work is to use a "winch-like" system. Pull the system down with a small pulley and some tether. Spring it back up. (or vise versa) It's super easy to get a very large reduction using a system like this and It is also very easy to change on the fly by adjusting the point at which the tether attaches to the arm.
