Adjustment of the centre stop
The centre stop regulates the amount of material
cut from the corners of the cross-rails.
The centre stop is adjusted as follows:
1. The adjustment screws (1) are located in each
side of the Teflon head (3) on the centre stop
(2). They can be turned in or out, to allow
more or less material to be cut from the corner
of the cross-rail.
The adjustment screws (1) are adjusted
exactly equal on both sides so that the
distance from the screw head to the centre of
the Teflon piece (3) is equal
Example:
Nose width 12 mm:
The width of the Teflon piece (3) is measured.
The screws (1) are adjusted exactly equal on
both sides, so that the distance from the screw
head to the centre of the Teflon piece (3) is 6
mm.
2. You can make minor adjustments if the width
of the cross rail should vary (e.g. 11.9 or 12.2
mm instead of 12 mm). Make a 45° cut in a
test piece on the cross-rail and offer it up to
the notch cut already made in the test stile
(see page F-2). If there is a gap in either of the
two corners, adjustments can be made on the
screws until an exact and tight joint is
achieved.
3. To achieve this balance, take a test piece of
centre-rail and cut one corner (4). Turn the
centre-rail to the opposite side of the knife
block up-side-down so that you cut in the
same corner. Place it against the centre stop
and bring the cutting block partially through. If
this causes a fine cut or the knives do not
touch the centre-rail, the two screws are not
balanced with each other. The adjustment
screws are balanced until the cut is correct.
It is particularly important to get this balance,
when frames are made with single cock-beads
on top and bottom rails. If the two corners are
not taken off exactly equal, there will be a gap
on one corner and an over-tight joint on the
other. This will also produce frames that are
not square.
