thicker than the rated capacity for your Shear/Brake.

2. Scribe the cutting mark on the material.

3. Slide the material between the UPPER CUTTER (#33) and the LOWER CUTTER (#31) so that the UPPER

CUTTER is positioned directly above the mark as shown in Figure 8.

4. While holding the material steady, lower the HAND LEVER (#6) until the material has been cut.

Angle Bending

1. Make sure the material you will be bending is within the capacity of the tool. Do not use material that is

thicker than the rated capacity for your Shear/Brake.

2. Use the appropriate BENDING TOOLS and BENDING PRISM radius for your needs. Refer to the

ASSEMBLY Step for adjustment.

3. Mark the workplace where you want to bend the material.

4. Place material above the BENDING PRISM (#24).

5. Align the bending mark with the front edge of the BENDING TOOL (S).

6. Lower the HAND LEVER (#6) until the desired angle has been formed. Use a protractor or other measuring

tool to ensure accuracy.

Pan forming

The Hand Brake Roll can used to make various sizes of pans.

1. Pre-measure and cut your material before bending. Notch the corners according to the desired lip height as

shown in Figure 9.1.

2. Insert material between the BENDING TOOL (S) and BENDING PISM. Bend the material until a 90-degree

angle has been formed as shown in Figure 9.

3. Rotate the material 90-degree counterclockwise. Allow the completed side to extend just beyond the dies.

Bend the second side.

4. Repeat Step 3 for the third side.

5. Rotate to the final side and insert work piece between the dies. Your formed sides will be on the outside of

the dies.

6. Before bending tap one corner nearer to the middle of the machine as shown in Figure 9.3. This will allow

the material to clear the UPPER DIE when raised.

7. Bend the fourth side.

8. Using a block or piece of wood, tap the comer of material back into place.

Radius Bending

Radius Bending is most used to make cylinders and cones, as shown in Figure 10. Both shapes are formed by

making a series of small, closely spaced bends in the work piece.

Figure 10 – Radius bending

For cylinders, the bends are evenly spaced, i.e. every bend is identical. For cones, simply move one side of your

stock out further than the other every time you make a head.
