Positive feed tools and methods of use that include a spindle with a distal end configured to receive a tool bit. The spindle is movable in a forward direction for the tool bit to act on a workpiece, and a retract direction to move the tool bit away from the workpiece. The spindle is configured to retract to a home position at which an air motor that drives the spindle is shut off. The feed tool includes a clutch to prevent jamming of the spindle at the home position in the event the air motor is not shut off at the proper time.

An insulation installation system and method of installing insulation in a wall structure for a modular construction unit. The insulation installation system includes an insulation in-feed table, an insulation out-feed table, an insulation saw assembly, and an insulation unload tool. The insulation in-feed table moves a batt of insulation thereon. The insulation out-feed table receives the batt of insulation from the insulation in-feed table. The insulation saw assembly includes an insulation saw that cuts the batt of insulation into a cut insulation having a size to fit into a wall cavity of the wall structure. The insulation unload tool grabs the cut insulation from the insulation out-feed table and places the cut insulation into the wall cavity of the wall structure.
