METAL BENDER OPERATING & MAINTENANCE INSTRUCTIONS Model Nos: CCB1 & CCB2

Operation: Using the Stop Block

IMPORTANT: Read page 3 before you proceed to this section.

Purpose of the Stop Block

The stop block prevents the material from rotating while a forming die in the handle bends the material around either the centre pin or another die that has been installed on the centre pin.

When you are bending material, the stop block will be located (using a hitch pin) at one of the five large holes in the middle of the ring assembly’s loop. (The large hole at the open end of the loop is for the centre pin.) You will have to determine by trial which hole you will use, depending on the thickness of the material being bent, the size of the centre-pin die, and the orientation of the stop block.

Positioning the Stop Block

The stop block can be placed in several positions by rotating it on the hinge pin or by turning it upside down and rotating it on the pin. However, only four of the possible positions are used when bending. Throughout this manual, those four positions are identified by a number (refer to the illustration at right).

CAUTION: Always position the stop block off-centre to the right—no matter which face is used against the material. If positioned off-centre to the left, the block will turn and the material will slip in the Bender.

To position the stop block (that is, to select the proper orientation and the proper hole in the loop):

1. Connect the handle to the centre pin of the loop, with the appropriate die installed on the centre pin.

2. Install the appropriate die at the appropriate hole in the handle.

3. Inset a piece of the material to be formed. With the handle all the way back (anticlockwise), install the stopblock—in the orientation that places it as close to thecentre pin as possible.

IMPORTANT: Always use the loop hole that places the stop block as close to the centre pin or die as possible, while leaving space for the material to be inserted.

If there is too much space between the stop block and the centre pin or die, turn the block to a different orientation or move the block one hole closer to the centre.

Positioning the Block Support

The block support must be located under the stop block as shown, to keep the block centered vertically in the loop.

Install the support in the appropriate loop hole where it will support the stop block but not interfere with inserting the hitch pin all the way through the block hole and the lower hole in the loop.

Clamping

If the stop block is positioned correctly, the material will normally not have to be clamped in the

Bender. However, when you are making special bends or need precise dimensions, it is helpful to clamp the material against the stop block using a vice-grip pliers as shown at right.
