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-4). 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) (fig. F-5-2).
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 make another cut. 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.
