US 8,146,630 B2 · Method of changing the distance between a rotary cutting tool and a work surface

Abstract

A method of changing the distance between a rotary cutter disposed on a carriage assembly and a work surface. The method includes the steps of providing a first mechanism on the carriage assembly for making small distance changes between the rotary cutter and the work surface and providing a second mechanism on the carriage assembly for making larger distance changes between the rotary cutter and the work surface. The user selects one of the first and the second mechanisms to adjust the distance between the rotary cutter and the work surface and then activates the selected one of the first and the second mechanisms. Activation of the second mechanism automatically disengages the first mechanism.
