A contact trip adjustment assembly (110) includes a forward trip member (112), adjustment pinion (514), adjustment nut (518), adjustment knob (510), and spring. The forward trip member can engage a workpiece and include a plurality of threads disposed about a first axis. The forward trip member can be axially translatable along the first axis between preset and actuated positions. The adjustment pinion (514) can be rotatably disposed about the first axis and include a first gear. The adjustment nut (518) can be coupled to the adjustment pinion for common rotation about the first axis. The adjustment nut (518) can be axially slidable relative to the adjustment pinion and can be threadably engaged with the threads of the forward trip member. The adjustment knob (510) can be rotatably disposed about a second axis and can include a second gear meshingly engaged with the first gear. The spring can bias the forward trip member toward the preset position. |
