Router Table Lift for plunge router

thingiverse

This gives precision lift capability to a standard plunge router enabling it to be mounted under a table. The hardware used will depend on the router model and table utilized. For instance, my silver line router had convenient points in its aluminum base to drill some holes and anchors the threaded rods nicely with a few washers. Mileage may vary. The only 3D printed part requiring specific hardware is the metric 8mm quad-start 2mm pitch lead screw, identical to that used by most 3D printers' Z axis lead screws, which should be readily available at an affordable price. The basic premise involves one side of the arm being stationary and another designed to move up and down on a turning lead screw. The lead screw must be mounted at the router base end for rotation but also pivoting, as the arm arc causes the bottom end of the lead screw to move in and out. A convex washer was used for this purpose. To mount the threaded rod to the rocker arm, the included axles should be glued into place once inside the rocker arm. Plastic weld provided a very strong bond, but care must be taken not to get it onto the rocker arm as this would prevent it from pivoting correctly. Hardware goes as follows, top to bottom: Stationary side: - 3mm threaded rod - Locking nut - Washer - Convex washer - Router base (through drilled hole) - Big ole gap - 8mm bolt running laterally between rocker arm holes with a 4mm hole drilled perpendicular, through which the threaded rod can pass - Washer - Locknut Rotating side: - 3mm threaded rod - Double locknut (this is where the socket goes to wind the router up or down) - Washer - Convex washer - Router base - Big ole gap - Coupler to 8mm lead screw (with zip ties to stop it spreading under load. Really, really needs reworking as this is a total bodge) - 8mm lead screw threaded onto the threaded 3D printed part
