Male Joint
Depending on accessibility lay female worktop
into position on units. Lay male worktop on top
and support other end. Using a pencil draw
round the female cut onto the male. If
inaccessible lay female onto male. Depending
on a right or left hand joint, the pencil line may
need to be transferred on to the other side. Due
to the difference between the cutter and the
guide bush diameters, the cutter path (or cut
line) will be 8.5mm over from the edge of the
template, therefore either measure 8.5mm or
use a packing piece of this size to offset the
template by this amount to ensure the cutter cuts
along the pencil line.
The postformed edge of the worktop must
always be in contact with the location bushes,
this means that to cut a male right hand joint, the
worktop must be inverted. Remembering to cut
into the postformed edge.
I
Insert two location bushes into male holes (M)
as shown, label facing down.
I
Place template across the width of the
worktop and clamp securely to worktop.
I
Set cutter depth. Plunge router and cut the
male joint before finally cutting the work-top to
length. A series of passes should be made
feeding from left to right.

Out-of-square Joints (max. 3°)
*
It may not be possible to position all joints at
90°, in this case it is the male part of the joint
that has to be adjusted.
The length stop has a mitred end which is used
to set up for an out-of-square joint up to 3°.
To mark out an out-of-square joint, first lay the
female worktop on the cupboard carcass in its
correct position. Next lay the male section of the
worktop on the carcass and on top of the female
section of the worktop. Support the other end of
the male worktop. Using a pencil and from
underneath the worktop mark around the female
joint onto the male section of the worktop, if
access is difficult lay the female worktop onto the
male worktop, support other end and mark with
pencil from above. This drawn line is the male
joint cut line.

Please Note:
Out-of-square joints are possible, but the
finished joint will not be as good as a 90° joint.
