Abstract: A log rest assembly for use in a portable sawmill has a log rest post mounted on a first end of a cylindrical mounting rod. The log rest post is fixed to a cylindrical log rest sleeve such that the log rest post remains perpendicular to said mounting rod. A stationary collar is affixed to the mounting rod. A compressible collar is mounted onto the mounting rod between said cylindrical log rest sleeve and said stationary collar. The compressible collar and the stationary collar provide pressure on the cylindrical log rest sleeve to constrain rotation of the log rest in relation to the mounting rod.

Abstract: A sawmill and a kit for forming the sawmill has a support assembly, a sawhead, a log bed and a carriage. The support assembly retains a motor relative to a drive bandwheel and a free bandwheel in a sawmill. The support assembly has a first platform orientated on a first plane, where the first platform securable to an axle of the drive bandwheel. The support assembly has a second platform orientated on a second plane, where the second platform securable to an axle of the free bandwheel. The support assembly also has a centre platform coupled to, and between, the first and second platforms, where the centre platform is orientated on a third plane that is vertically spaced apart from the first and second planes. The centre platform is configured to support the motor above the axles of the drive bandwheel and the free bandwheel.

Abstract: The present invention relates to a blade guide and a blade guide assembly for adjusting an elongate blade of a sawmill, where the blade having a longitudinal axis. The blade guide includes a guide with a blade surface for lateral contact with the blade, a shaft extending from the guide, a shaft block having a bore extending therethrough, the bore dimensioned to slidably receive the shaft therethrough, and a trunnion block pivotably coupled to the shaft block about a pivot. The pivot is orientated generally parallel to the longitudinal axis of the blade, and the trunnion block is adapted to be securable to the sawmill. Thus, pivoting the shaft block and, thereby, the shaft relative to the trunnion block, causes the guide to pivot and angularly adjust the blade about the longitudinal axis.

Abstract: A braking system for a rotating member has a lever with an apex where a first arm meets a second arm. The apex is rotationally secured to a support. A band wraps around the circumference of an end of the rotating member. A first end of the band is secured to the support. A second end of the band is secured to the second arm. A resilient member is secured to the first arm and the support. An actuator is secured to the first arm. The resilient member biases the first arm, placing the band in frictional engagement with the circumference of the rotating member, and activation of the actuator directs the first arm, which relieves the frictional engagement of the band with the circumference of the rotating member. The actuator may be connected to a throttle or a brake control.

Abstract: A laminated rail for a sawmill bed comprises an outer plate having a middle body portion, a top portion, and a bottom portion; and an inner plate secured to the outer plate, the inner plate having a middle body portion, a top portion, and a bottom portion. The middle body portion of each of the inner plate and the outer plate may have substantially the same cross sectional tacking configuration to allow the inner plate to be matingly received by the outer plate. A channel may be formed between the top portion of the inner plate and the top portion of the outer plate, the channel being shaped and dimensioned to receive and secure a track in a sandwich grip.

Abstract: 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.
