A truss plate detector preferably includes a first sensor array and a second sensor array. The first sensor array includes a plurality of sensors arranged to detect truss plates on a first side of a truss. A second sensor array preferably includes a plurality of sensors arranged to detect truss plates on a second side of a truss. A circuit is configured to receive signals from the first and second sensor arrays and to notify a user when one or more truss plates are missing or misaligned. For instance, the sensors in the first and second sensor arrays are preferably arranged opposite each other along the arrays. The truss plate detector can then be configured to notify a user when a sensor in the first sensor array detects a truss plate but neither a corresponding sensor nor an adjacent sensor in the second sensor array detects a truss plate. By providing a plurality of sensors in each array, the truss plate detector is capable of detecting a lateral position of truss plates on a truss being fed through the truss plate detector.

A chipper machine for simultaneously preparing a flat surface on a workpiece and comminuting material removed from the workpiece to produce the flat surface, in which several individually removable chipper knives are mounted on a hub mounted detachably on a rotatable arbor. A workpiece-supporting anvil includes a drop front section to permit removal of the chipper head from the arbor. The hub and arbor are steeply tapered to allow the chipper head to be easily removable from the arbor, and the chipper machine is provided with sharpened chipper knives by replacement of the entire chipper head. The several chipper knives are removed, sharpened, replaced, adjusted and again ground to cut uniformly with the chipper head removed from the chipper machine.
