Abstract
A plunge router adjustment mechanism including a drive shaft longitudinally fixed but rotatable in a base plate and extending towards an opposite end of the plunge router. A carriage moveable along the drive shaft is connectable to the router housing. Optionally, a sub-carriage, moveable along the carriage and directly attached to the housing, allows fine adjustment of the housing relative to the base plate. Optionally a coarse adjustment stop member is releasably fixable along the drive shaft for coarse positioning of the housing relative to base plate.
Claims31
A plunge router adjustment mechanism comprising:
- an elongated member having first and second ends;
- a mounting member on said first end adapted for mounting said first end in a base of a plunge router;
- a carriage adjustably moveable along the elongated member allowing some plunging movement, and an adjustable connection adapted to engage the carriage relative a plunge router housing;
- a stop member adjustably positionable along the elongated member to define end of travel of the carriage in a direction opposite the base along the elongated member;
- so that when installed, adjustment of said stop member along said elongated member sets the maximum distance between router bit and the router base.
A method of adjustment of a plunge router comprising:
- incorporating a first member to adjust the distance between a bit and a base on the router over a range;
- positioning said member so that it can be accessed and operated from either through said base or at an opposite end of the router.
A plunge router adjustment mechanism comprising:
- a plunge router having a housing with a bit chuck at a base end, an opposite end, and a plunge mechanism biasing a base to an extended position, but allowing movement of a base over a range between extended and nearest positions;
- means accessible from the base end and the opposite end of the housing to adjust and fix the distance between the base and the housing over said range.
