Abstract
A tool for marking sheet metal prior to bending in a bending brake, includes a scale having a first end, an opposite second end, a longitudinal axis, and four faces. Each of the four faces include a plurality of marking stations. A cross member is rotatably connected to the first end of the scale. The cross member has a surface which is disposed perpendicular to the longitudinal axis, and is configured to abut the edge of the sheet of metal. The tool is positioned at a first location on the sheet of metal and marks are made at the marking stations. The tool is then moved to a second location on the sheet of metal and a second set of marks are made. The two sets of marks are used to align the sheet of metal with the bend line of a bending brake so that accurate bends can be made.

A tool for marking sheet metal prior to bending in a bending brake, the sheet metal having an edge, the tool comprising:
- a scale having a first end, an opposite second end, a longitudinal axis, and four faces, each of said four faces including a plurality of marking stations;
- a cross member rotatably connected to said first end of said scale, said cross member having a surface which is disposed perpendicular to said longitudinal axis;
- a screw which rotatably connects said cross member to said first end of said scale, said screw oriented along said longitudinal axis of said scale;
- and
- a nut inserted into said first end of said scale, said nut engaging said screw;
- wherein the cross member rotates about the screw.
A method for marking sheet metal comprising:
- (a) providing a sheet of metal having an edge;
- (b) providing a marking implement;
- (c) providing a tool for marking said sheet of metal, said tool including;
- a scale having a first end, an opposite second end, a longitudinal axis, and four faces;
- at least one of said four faces including a cut marking station, a first bend marking station, and a second bend marking station;
- a cross member rotatably connected to said first end of said scale, said cross member having a surface which is disposed perpendicular to said longitudinal axis;
- (d) rotating said scale so that a desired face is disposed perpendicular to said sheet of metal;
- (e) at a first location on said sheet of metal, positioning said surface of said cross member into abutting contact with said edge of said sheet of metal;
- (f) using said marking implement to make a cut mark, a first bend mark, and a second bend mark on said sheet of metal;
- (g) at a second location on said sheet of metal, positioning said surface into abutting contact with said edge of said sheet of metal;
- and,
- (h) using said marking implement to make a cut mark, a first bend mark, and a second bend mark on said sheet metal.
A method for marking sheet metal comprising:
- (a) providing a sheet of metal having an edge;
- (b) providing a marking implement;
- (c) providing a tool for marking said sheet of metal, said tool including;
- a scale having a first end, an opposite second end, a longitudinal axis, and four faces;
- at least one of said four faces including a cut marking station, a first bend marking station, and a second bend marking station;
- a cross member rotatably connected to said first end of said scale, said cross member having a surface which is disposed perpendicular to said longitudinal axis;
- (d) rotating said scale so that a desired face is disposed perpendicular to said sheet of metal;
- (e) at a first location on said sheet of metal, positioning said surface of said cross member into abutting contact with said edge of said sheet of metal;
- (f) using said marking implement to make a first bend mark, and a second bend mark on said sheet of metal;
- (g) at a second location on said sheet of metal, positioning said surface into abutting contact with said edge of said sheet of metal;
- and,
- (h) using said marking implement to make a a first bend mark, and a second bend mark on said sheet metal.
