Abstract: A rotor height-adjustment mechanism is disclosed which is designed for mounting to the adjustment rod of a router mounted in a router table. The mechanism includes a flexible shaft member which may flex around and over interfering projections extending from the router housing. The flexible shaft has an engagement end with a threaded, hollow insert which engages the threaded adjustment rod of the router and further has a driving end with a drive means engagement member such as a socket which permits the height of the router within the router table to be adjusted.
