Adjustment of the centre stop (15)
The centre stop (15) regulates the amount of material cut from the corners of the cross-rails.
The centre stop is adjusted as follows:
1.
The adjustment screws are located in each side of the Teflon head on the centre stop. 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 are adjusted exactly equal on both sides so that the distance from the
screw head to the centre of the Teflon piece is equal.
Example:
Nose width 12 mm:
The width of the Teflon piece is measured. The screws are adjusted exactly equal on both sides,
so that the distance from the screw head to the centre of the Teflon piece 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 G-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. 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.
