A cutting fluid delivery controller for a sawmill, and methods and systems for controlling delivery of cutting fluid to a saw blade in a sawmill. The saw blade is driven by a motor. The speed of the motor is regulated by a throttle lever having an idle speed position and a cutting speed position. The cutting fluid delivery controller includes a fluid valve configured to automatically turn on a flow of cutting fluid to the saw blade when the throttle lever is set to the cutting speed position, and to automatically turn off the flow of the cutting fluid when the throttle lever is set to the idle speed position. The cutting fluid delivery controller interconnects the fluid valve and the throttle lever to allow the operator to simultaneously control operation of the saw blade, and the flow of the cutting fluid to the saw blade, with a single operator manipulable actuator.

Circular saw blade guide pads, circular saw guide assemblies including the guide pads, circular saws including the guide assemblies, methods of manufacturing the guide pads, and methods of utilizing the circular saws. The guide pads include a pad body that includes a pad material. The pad material includes a first plurality of small graphite particles, a second plurality of large graphite particles, and at least one additional component that includes a cured resin material. The guide assemblies include a guide arm and a guide pad operatively attached to the guide arm. The circular saws include at least one circular saw blade that defines a first blade side and an opposed second blade side, a first guide assembly positioned on the first blade side, and a second guide assembly positioned on the second blade side. The methods include methods of operating the circular saws and/or manufacturing the guide pads.

Provided are a porous media bearing for a band saw, a band saw for cutting cant and a method of cutting cant using the band saw. The band saw has a continuous loop blade supported by a drive wheel and first and second support arms having porous media bearings. A location of a blade cutting section, an angle of the blade in relation to the cant being cut, and tension on the blade can be adjusted by moving the first and second support arms.

An anti-vibration arrangement for a band saw blade in a band saw machine, which is constructed to cut a workpiece by shifting the endless band saw blade running in a circulating manner to a cutting direction, wherein nozzles are provided for injecting high-pressure cutting liquid toward each side face of the body of the band saw blade on the entering-side where the band saw blade enters into a cut groove of the workpiece formed by the band saw blade in the cutting process of the band saw machine.

A method for constructing a lower section of a sawmill carriage assembly comprises holding structural components between a pair of metal plates, and affixing the plates and the structural components together. The structural components may include wheels that guide the sawhead in linear movement along a track on a sawmill bed, to which the carriage base is attached. The structural components may also include a track cleaning system disposed between the metal plates. The track cleaning system maintains optimal track conditions.
