Here’s an idea I had and hopefully one of the major companies will pick up on it and make it. The picture says it all. It’s a gear box that is used with the router (either built in or added on) to allow the out-drive to be positioned off center. This would add major stability when using it free hand by keeping the center of mass and more of the plate over the work piece.
When I’m viewing this on my browser, half the picture is cut off by the window. I guess you may have to save the picture to view it entirely.
