USING THE STOP BLOCK
IMPORTANT: Read page 4 before you proceed to this section.
THE 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.
