Now the step is shortened to your individual step
size. To do this, position yourself at the end of the
staircase where the additional stair stringer element
is mounted.
Before you transfer the gradient of the first step
to the outer stair stringer, use an angle to ensure
that the step is aligned at a 90° angle to the stair
stringer.
Measure with a folding rule from the top edge of
the step (see marking in the photo) and mark the
gradient of your first step (can be found in section 9
or the Häfele catalogue) with a pencil on the outer
stair stringer.
Set up an angle at the front end and transfer the
marked dimension continuously to the outer stair
stringer.
Repeat the procedure on the inner stair stringer.
Make sure again that the steps are aligned at 90°
to the stair stringer.
Measure from the top edge of the step.
Saw off both stair stringer elements at the marked
cutting edge. Use a Japanese saw or circular saw
for this. If the expansion sleeve is at the cutting
edge, pull the sleeve out of the drill hole before
sawing.
