OPERATING PROCEDURES

General

Your tool is capable of many different types of bending operations. Materials which can be shaped include steel, iron, brass, wrought iron and aluminum.

To determine how to properly set the tool up, you first must determine what type of bending opera- tion you wish to perform. Round shapes, angles or spiral operations are each described in the following sections. The numbers in parentheses relate to the reference number on the exploded parts view on page 8.

When performing the bending operations, be aware of the “spring-back” characteristic of cer- tain materials. This will require that you overbend the material to a certain degree to end up with the desired degree of bend. Different materials have differing degrees of springback. Do a test bend to determine how much “spring-back” you will need to compensate for.

Round Operations

1.Make sure the Die Mounting Plate (4) is attached to the Body. Refer to Figure 1 for the hole positions needed for Round Operations.

2.Make sure the Stop (2) is loose.

3.Move the Vise Assembly (5-9 & 15) to the rear position on the arm of the Mounting Plate.

4.Screw the Round Die Mounting Shaft (28) into the Mounting Plate.

5.Set the Round Die (29) onto the Mounting Shaft.

6.Move the Bending Block Assembly (16, 17, 22-24) back all of the way. You may have to release the Bending Block Locking Plate (21) by loosening the two Hex Key Bolts (20). Do not secure the Locking Plate at this time.

7.Set stock against the Round Die and close the Vise so that it clamps the work securely against the Die.

8.Move the Bending Block in until it is up against the work and its Face (16) is even with the Vise Face (8). Secure the Bending Block by tightening the two Bolts.

9.Move the Bending Block to the left with the Handle (27) until you have achieved your desired angle bend, remembering to account for “spring-back”.

10.If you wish to do repeat bends at the same arc, tighten the Stop at the point where you finished making your bend and tighten it.

11.When you wish to do complete 360° rings, make sure you clamp the very end of your workpiece in-between the Vise and the Die. Bend your stock all the of the way around, and cut off the excess.

12.To make springs, loosen the Stop (2), and lift the stock to be formed slightly as you bend the stock around the Die. When starting and fin- ishing the spring, make a complete 360° ring as described in Step #11.
