Tool for curving structural framing components

1 . A system for shaping a workpiece, comprising:

a base having an upper side and a generally opposed lower side to separate an upper region coincident with the upper side from a lower region coincident with the lower side, and being securable to a substructure at the lower region;

a blade control apparatus;

a first indenting blade connected to the blade control apparatus for indenting a first portion of the workpiece when the workpiece is positioned in the upper region;

a second indenting blade connected to an upstanding support post member and controllable by the blade control apparatus for indenting a second portion of the workpiece when the workpiece is positioned in the upper region;

a handle connected to the blade control apparatus wherein the handle rotates about an axis to move the first indenting blade and the second indenting blade into indenting contact with the workpiece;

a master base plate having an upper surface and a lower surface with a plurality of first mounting features on the upper surface and a plurality of securement apertures on a side surface, wherein the master base plate is secured to the base adjacent the upstanding support post member below the second indenting blade so that the first mounting features of the master base plate are open to the upper region; and

one or more removable workpiece support modules having two support module sides and a width, positionable on the upper surface of the master base plate, an elongated support module channel on an upper surface of the support module for receiving a fastener and aligned with the second indenting blade, and a second mounting feature configured to secure the one or more removable workpiece support modules to the upper surface of the master base plate, and

wherein the elongated support module channel receives an indented portion of the workpiece when at least one of the first indenting blade and second indenting blade are moved into indenting contact with the workpiece.

2 . The system of claim 1 wherein securement of one or more of the workpiece support modules to the master base plate creates a total width that corresponds to a workpiece width of the workpiece.

3 . The system of claim 2 wherein the workpiece width is defined between opposed flanges of the workpiece, which flanges are connected together by a web.

4 . The system of claim 3 wherein the workpiece support modules are securable to the master base plate in immediate adjacency to one another.

5 . The system of claim 1 wherein the second mounting feature of the one or more removable workpiece support modules coordinates with one of the first mounting features of the master base plate.

6 . The system of claim 5 wherein the first mounting features include receptacles, and the second mounting features include at least one of receptacles, apertures, and protrusions that are axially alignable with the receptacles of the first mounting features.

7 . The system of claim 6 including fasteners for securing the workpiece support modules to the master base plate by extending through the respective apertures of the second mounting features, and into the respective receptacles of the first mounting features.

8 . The system of claim 1 wherein a first one of the workpiece support modules is removably securable to the master base plate at a position adjacent to the first indenting blade, with a first side of the first workpiece support modules facing the first indenting blade having a first slot for receiving at least one of the first indented portion of the workpiece and the first indenting blade.

9 . The system of claim 8 wherein the first side of the first workpiece support module includes a second slot for receiving a flange portion of the workpiece.

10 . The system of claim 9 wherein a second side of the first workpiece support module facing generally oppositely from the master base plate includes a third slot for receiving at least one of the second indented portion of the workpiece and the second indenting blade.

11 . The system of claim 10 wherein each of the workpiece support modules includes a slot for receiving at least one of the second indented portion of the workpiece and the second indenting blade.

12 . The system of claim 1 wherein the master base plate is integrally formed with the base.

13 . A method for shaping a workpiece with the shaping system of claim 1 , the method comprising:

(a) selecting one or more of the workpiece support modules from a set of workpiece support modules;

(b) securing the selected ones of the workpiece support modules to the master base plate;

(c) positioning the workpiece in the upper region at the selected ones of the workpiece support modules; and

(d) actuating the handle to move the first and second indenting blades with respect to the base and into indenting contact with the workpiece.

14 . The method of claim 13 wherein the first indenting blade is moved into indenting contact with the workpiece to form an indent in the first portion of the workpiece, and the second indenting blade is moved into indenting contact with the workpiece to form an indent in the second portion of the workpiece.

15 . The method of claim 14 wherein the first portion is perpendicular to the second portion.

16 . The method of claim 13 including replacing at least one of the workpiece support modules with another of the workpiece support modules of the set of workpiece support modules by removing the at least one of the workpiece support modules from the master base plate and positioning another workpiece support module onto the first mounting features of the master base plate.
