ABSTRACT:
A hand-operated sheet metal layout and marking tool supports sheet metal on a base where it may be laterally guided by a fence adapted for use at either side of the sheet metal, and permanently marks location of bend lines to be made, by means of a die-head carrying a row of pointed dies and pivotal for simultaneously impinging the dies against the sheet metal. The base has a recess along it in alignment with the row of dies to permit the sheet metal to yield for easier indenting. Spacing between the dies is easily set by means of a scale fixed on the base, and a die carrier ring carrying each die, that slides along a grooved rod coaxial with the similar rings carrying the other dies and can be fixed in position by a set screw that rides in the rod groove. When desired, any die can be swung out of operation, and all can be swung together by rotating the rod.
