ABSTRACT:
A jig is provided for aligning the cutting depth of knife blades on a cylindrical rotary cutter head of a rotary planar machine. The jig has a tripod support adapted for spacing the jig radially over the cutter head. An indexing member circumferentially positions the jig with two radially adjustable knife adjustment members aligned longitudinally and radially over a knife blade. In use, the jig can be calibrated over a knife blade so that the knife blade can be removed and a replacement knife blade installed with the same radial projection along the longitudinal extend of the cutter head. Alternatively, or in addition, each of a plurality of knife blades of a cutter head can be set to the same longitudinal radial projection.
