Building a docking station isnt too hard Brian. What your friend was talking about is features built into Norm's workbench. This is where Norm placed his dedicated mortiser; it lifted out for storage underneath the bench in a pull out drawer.
Start with a frame built from 2x4's. Lay this upside down on the floor and insert 1/4" hardboard and 3/4" plywood sections that have the docking plate cut out. You will then install 2x4 cross pieces so they are centered on the front to back edges to provide support. The final piece to add is a small plywood cleate that overlaps your plate and the rear edge of the table top. This is fastened only to the removeable plate. When you flip the table right side up your plate should pop out by lifting on the front edge first. Then all you need to do is mount your tool to the removeable plate. You can also build a tall narrow cabinet with supports to store your tools in while mounted to these plates.
