Abstract
Abstract A hand-operated profiling machine includes a cutter-holding head supported on a support which is mounted for movement toward and away from a table. The head is mounted in a cover which is supported on a pair of guide rods extending through linear bearings fixed to a shaft extending through ball bearings mounted on the support, the shaft extending perpendicularly to the table. The head is pivotable about and movable toward and away from the shaft. An adjustable template is supported on the support and guides the movement of a guide pin mounted on the head.
