dovetail marker

A device for marking the dovetail tenons or mortises on the respective boards. The two plates of the frame are set at right angles to each other, and each has a scribing edge adapted to mark its side of the dovetail; one plate is adjustable to regulate the widths and distances, the adjustable gauge plate affording a guide in setting the marker for the next scribe.

There are several varieties. One consists of a pair of circular saws running in planes, bearing such angular relation to each other as to give the required obliquity to the kerfs. In dovetailing-machines rotary cutters work to a given line, and also remove the material between the cheeks of opposite dovetail tenons. Gangs of circular saws on a mandrel are constructed and arranged to do the same. 2. A small tenon-saw adapted for cutting dovetails. It has fifteen teeth to the inch, and is usually about nine inches in length. 3. A saw having two cutting edges, one at right angles to the other; one edge makes the side kerf, the other the bottom kerf.
