Router life that will work with any plunge router
I don't recall where I saw the idea or I'd link to it. The cabinet is similar to the "Norm style" router table, rectangular cabinet with a compartment in the center where the router sits and a dust collection port out the back. The router lift is simply a pad of lumber with a piece of threaded rod attached to the bottom. The pad of lumber sits against the top (or bottom in this case) of the plunge unlocked router. The bottom of the compartment directly underneath the router has a threaded T nut, the other end of the threaded rod has a crank. Turn the crank and it pushes on the top of the router. You'd need some sort of guides to insure the pusher block travels straight up and down. The downside to this type mechanism is it might require bending over quite a ways to turn the crank. If you wanted to be clever you could use a 90o gearbox and put the crank outside the cabinet.
