The present disclosure provides systems, methods and assemblies comprising one or more tapered feed rolls. Tapered feed rolls may be used to change the rate and direction of workpiece travel along a processing line while retaining the workpieces in sequential order. Routing workpiece flow with tapered feed rolls may allow the workpieces to be tracked along one or more processing lines, and may reduce the operational space required for workpiece processing.

A saw for performing chop cuts has a base, a cutting unit, and a pivot joint pivotally mounting the cutting unit to the base to enable the cutting unit to pivot towards or away from the base to perform chop cuts. The pivot joint has a cup-shaped section having an open end, a cap rotatably mounted on the open end of the cup-shaped section to form a sealed enclosed space within the cup-shaped section and cap, and a spring located inside of the sealed enclosed space. The spring is connected between the cup-shaped section and the cap. The spring applies a rotational biasing force between the cup-shaped section and the cap to urge relative rotation movement between the two.

A cutting apparatus can include a frame, a carriage, a saw, and a post. The frame can have a first height defined along a vertically-extending height axis between a first bottom end and a first top end. The carriage can be mounted on the frame for adjustable positioning relative to the frame along the height axis. The carriage can include a first aperture positioned with the frame and defining a cutting plane. The saw can be mounted on the carriage within the frame for sliding movement across the first aperture. The post can be mounted on the carriage. The post can have a second height defined along the height axis between a second bottom end and a second top end. The post can extend along the height axis above the first top end.
