I have one that is built in the early 80's one 3/4" plywood x3'x3'. The router is held by the plywood not by Plexiglas. I've made hole at 12" in the middle of the board, where the holes of the router were copied from its plate to the wood. Now underneath the other side 3" from the edge I put a 2x 4 pine. The 4" downward so it can be clamp to my Black & Decker workmate. I still use it to this day.

I do like this concept, because you can walk away with the router & more possibilities. Mine I have to unscrew leave the screw with the table, +++...
A very good system + it has a versatility that I see with this one than mine.
