Abstract
A sawmill apparatus includes first and second carriages for supporting first and second logging dogs therebeneath, with the second carriage being movable upon the first whereby to engage the ends of a log between the dogs. The carriages support the dogs at the end of steel baldes which are moved in a vertical direction by a combination of air cylinders and ball screws to provide the desired positioning of the log in a vertical direction. As the carriages urge the log between the blades of a bandsaw, rubber tired wheels are raised against the underside of the log for supporting cants or boards sawn therefrom and preventing splitting at the finally sawn edge.
