ABSTRACT:
A panel saw apparatus for cutting a straight line in a planar surface such as a boiler tube panel includes a guide rail arranged to be secured to the panel surface in a predetermined position and a cutting assembly mounted on the rail for movement along the rail. The cutting assembly includes a carriage mounted on the rail for movement along the rail, a brake for holding the carriage in a desired position relative to the guide rail during cutting operations, a cutting tool and tool housing pivotally mounted on the carriage and arranged to pivot toward the panel surface to enable a cutting tool covered by the housing to serially plunge cut a straight line in the surface, and a securing means for holding the cutting tool in various positions of rotation relative to the carriage. The brake is arranged to be automatically actuated and released by pivotal movement of the tool housing towards and away from its cutting position.
