Patent ID: 8020593

Claim:
A method of changing the distance between a rotary cutting tool and a work surface comprising the steps of: providing a carriage assembly upon which the rotary cutting tool is disposed, where the carriage assembly is adapted to be mounted beneath the work surface and the rotary cutting tool is adapted to be disposed at least partially above the work surface; providing a lift handle on the carriage assembly; selecting the lift handle to make coarse adjustments in the distance between the rotary cutting tool and the work surface; and moving the lift handle in one of a first direction and a second direction, wherein moving the lift handle in the first direction increases the distance between the cutting tool and the work surface, and moving the lift handle in the second direction reduces the distance between the cutting tool and the work surface; and wherein the step of moving the lift handle includes one of the steps of moving the lift handle vertically upwardly to move the carriage assembly and thereby the cutting tool in the first direction; and moving the lift handle vertically downwardly to move the carriage assembly and thereby the cutting tool in the second direction.
