A plunge router adjustment mechanism, comprising:
- a base including an aperture therethrough;
- a first column portion connected to the base, the first column portion defining an interior recess with a stop, the first column being configured such that the base aperture permits access to the interior of the first column portion;
- a second column portion adjustably connected to the first column portion, the second column portion suitable for at least partially supporting a motor housing;
- means for providing a biasing force, the means being configured to force the second column portion away from the first column portion;
- a threaded rod with a first and a second end, the threaded rod is pivotally connected, adjacent the first end of the threaded rod, to the second column portion generally opposite the connection between the first and second column portions and said second end forms a mechanical connection;
- and
- a nut disposed in the first column portion such that the exterior of the nut mates with the interior of the first column portion, said nut coupled to the threaded rod, said nut being capable of traveling between the end of the first column portion opposite the base and the stop, contact between the stop and the nut defining plunge depth;
- wherein plunge depth is adjustable from the base end.
