Unique to Axminster, this marking and mortice gauge is made from carefully selected hardwood and brass. Brass wear strips are inlaid into the gauge's head. Locking the head onto the stem is by means of a knurled brass thumb screw underneath which is a pressure plate to protect the stem from bruising. The lower movable pin for mortice marking is adjusted via a brass screw slide giving precise micro fine control. Maximum capacity 110mm.
