Abstract
A combination woodworking machine for attachment to an electric plunge router, which may be configured as a horizontal boring and slot mortising machine, an overarm router and a router table. An x-y-z table is mounted on a column supported by feet, and a plunge router with its base removed is mounted in various orientations on the column by sliding it onto steel dowels mounted on the column. An electronic speed control reduces the router speed for boring, and an electronic digital readout provides accurate measurement of horizontal movement of the table.
