Classification | Woodworking marking tool |
A mortise gauge or mortice gauge is a woodworking tool used by a carpenter or joiner to scribe mortise and tenon joints on wood prior to cutting. Mortise gauges are commonly made of hardwood with brass fittings. [2] [3]
Like the simpler marking gauge, a mortise gauge has a locking thumb screw slide for adjusting the distance of the scribe from the edge of the wood. It has two protruding pins, often called "spurs", [3] which are designed to scribe parallel lines marking both sides of a mortise at the same time. [4] One of the pins is adjustable, attached to a sliding fence, [5] so that mortises of different widths can be marked. [2]
Some mortise gauges are designed with one retractable spur, so that they can be used as marking gauges as well; [6] however, because the mortise gauge is an expensive and high precision tool, many carpenters prefer to have a separate marking gauge for general use. [5]
For complex joints, some mortise gauges have a double-beam design which allows the gauge to be wrapped around a tool such as a chisel for extra accuracy. [7]
