ABSTRACT:
The invention is an improved, hand-held, adjustable, graduated marking gauge and scribe for carpentry and related activities. It is used to mark work-pieces at a given distance from an adjacent edge or intersecting surface such as is encountered when fitting cabinets or trim to uneven wall surfaces, or in the spiling of boat planking or the marking of cut-outs relative to an edge. The device consists of a main body, upon which are marked scales and which is bent and formed at one end to create an edge follower and a corner follower and upon which is mounted a sliding and stoppable instrument holder which holds marking, cutting or other instruments, inserted therein, in an adjustable fashion. The displacement of the centre-line of the marking instrument relative to the edge follower or the corner follower is read on the scales at the corresponding cursor edge of the instrument holder.
