End broken by
manufacturers - not perfect!
5.3 Making knives from square
Set the moveable stop to position 1 as it is not used for breaking knives.
Scoring head is raised completely, breaking lever turned anticklockwise to its start
position, scoring shaft is pushed back and the rear stop is moved back.
Place a square onto the handling fork and rotate it a
quarter turn clockwise (Fig.21)
to produce the
knife edges fom the freshly broken sides of the glass.
Place the square using the handling fork onto the two pins and make sure that the corners
of the square are positioned into the notch of the front and rear stops
(Fig.22).
Move the rear stop by means of the rotatable knob carefully against the square making
sure you do not touch the corners.
The square is now held firmly between the two stops. Open and close the rear stop
2 or 3 times to ensure the glass is correctly positioned.
The handling fork lies loose underneath the square
(Fig. 23).
Lower the scoring head by means of the clamping lever down onto the square 2 or 3 times
then pull clamping lever tight.
Set the scoring mark selector to its short or long mark.
Score the glass by quickly and evenly pulling the scoring shaft to the end stop.
Rotate the breaking lever gently and
very slowly
clockwise to initiate the break.
The slower the better
.
Note: As the left end of the left hand 200 mm glass strip is machine
broken by the glass manufacturers and therefore geometrically not
perfect do not use this square for breaking knives (Fig.19).
Also, the outer square of the right hand 200 mm glass strip is
not used to make knives (Fig.20) for the same reason.

Note: The best knives are made using the
lowest breaking pressure.
They may take a minute or more to break!
