MAKING SHARP BENDS
fig.9
4.3.1
Installing the sharp angle bend attachment. The sharp angle bend
attachment has only one correct orientation as shown in fig.10. and should be
installed with the block support underneath it to raise it to the correct position
vertically within the loop. Counting from the outside of the loop towards the
centre of the bender place the block support in the third lower hole.
4.3.2
Rest the sharp bend attachment on the block support and secure it by dropping
a long hinge pin through the fourth upper hole and all the way through the hole
in the attachment into the hole in the lower part of the loop. The longer ‘tail’ of
the attachment should now be resting to the left of the loop spacer as shown in
fig.10.
4.3.3
Installing the handle. Counting from the outside of the handle loop towards
the centre of the bender align the sixth hole in the handle with the centre pivot
hole of the bender. Secure the handle by dropping a long hinge pin through
both loops.
4.3.4
Installing the handle die. Install the smallest die in the last hole in the handle
loop as shown in fig.11 using a short hinge pin.
4.3.5
Preparation of workpiece. Mark the position of the bend or bends onto the material.
These marks will represent the inside of each bend and therefore may be on different sides
of the material depending on the shape of the item you are making. ( If you are making
two right angle bends on the same side of the material, make the marks 3mm further apart
than the desired inside dimension after the bend.)
4.3.6
Making a bend. ( Before making a bend check that the bender is still firmly attached to the
bench or floor. The floor should be clean and dry and free from loose material. Wear non
slip shoes and check that the area is clear of personnel and will remain clear whilst you
are executing the bend.) Slide the material into the bender so that the first marked out
bend is aligned with the tip of the sharp angle attachment. (The material face that is
touching the tip of the sharp angle attachment will become the inside of the bend. See
fig.13 which shows the action of the bender when using the sharp angle attachment.)
4.3.7
Exert just enough pressure on the handle to hold the material steady in the bender and
check that the material is level. Make the bend with steady and even pressure until you
reach the desired finishing point as indicated in fig.12. Measure the angle and make any necessary adjustments.
4.3.8
Once the required movement for a particular angle has been established it can be repeated by the use of the fixed stop as shown in
figs.11 & 12. If the finish point of a bend falls between two holes use the adjustable stop as shown in fig.3

EXAMPLE - DOUBLE TUBE CLAMP
4.4.1
Below is illustrated a simple example of the bend sequence required to make a simple pipe clamp using both methods of bending. The
first two bends are around a 1” die mounted on the centre pin with the stop block in place. The last two bends are made using the
sharp angle attachment. To insert the workpiece in C & D it will be necessary to temporarily remove the centre pin. Dis-assemble the
handle to remove the finished piece.
