MANUAL TUBE BENDER ASSEMBLY AND OPERATION
Upon receipt of your new Tube Bender, assemble the Handle to the Tube Bender
Roller Support with the bolts supplied (see Figure 2 and 3).
Figure 3 shows the Bender Body with holes (A) drilled in the Base Foot and the
Vice Clamp Block. These are for mounting the Bender Unit permanently to a
Work Bench. Alternatively temporarily in a Vice by holding the Vice Clamp
Block.
The Holes marked (B) in Figure 1 are used to position the Guide Block (64/10).
This Guide Block can be positioned anywhere over the eight holes to achieve the
desired type of bend or radius. By moving the Guide Block from one side to the
other, the Bender may be operated in either a clockwise or counter clockwise
direction.
The Holes marked (C) are used for securing the Former to the Body of the
Machine. The Body offers two options for positioning the Former. The outside
Holes are used for the small Formers and the inside Holes are used for the larger
Former. The larger Formers can be located in both sets of Holes but unless a large
bend angle is required, it is not recommended to locate the larger Former in the
outer two Holes.
The Hole marked (D) is securing Hole for the Bar Stop Assembly. This should be
bolted into position when you receive your machine.
Figure 2 shows the Tube Roller Support Frame and Handle assembled. Early
models had four Holes for the location of the Guide Roller, more recent models
have six. This allows better bending on the 1/2” and 5/8” Round Tube.
Figure 3 is a schematic diagram showing a side of elevation of the assembled
Bender. To change a Former it is a simple matter of removing the Pivot Pin. Once
the Pivot Pin has been removed, the Support Assembly (Fig.2) can be removed
leaving the Former bolted to the Body. Simply unbolt the Former and replace it
with the size Former you require. Replacing the Support Assembly is a reversal of
the removal procedure.
The Guide Roller can be repositioned to achieve the type or radius of bend you
require.
