<p>A mitre box has an integrally formed synthetic resin support member which includes a platform portion, a corner post with right angularly disposed faces, a pair of clamp posts spaced from the corner post and a saw guide post disposed between the clamp posts. The corner post has a transverse channel bisecting the 90 DEG angle defined by its vertical faces, and the saw guide post has a channel aligned therewith so that a saw blade may be guided when seated in these two cooperating channels to effect a 45 DEG cut in a workpiece abutting one of the vertical faces of the corner post. Clamp assemblies are adjustably mounted in the clamp posts and include elongated members which are adjustably moveable therein relative to the cooperating vertical faces of the corner posts.</p> |
