Cutting the Bolt Recesses
When the joint has been tested, proceed as
follows to cut the recess for panel butt
connectors on the underside of the worktop.
The same cutter and guide bush are retained
and used with the integral bolt recess slots in the
jig to produce the recesses for the panel butt
connectors. The bolt recess position can be
gauged approximately 150mm from the edge of
the postform edge, or where access is possible
with kitchen units. Mark with pencil both
positions on the underside of the worktop.
Insert the location bushes into the Yellow dot
holes as shown.
■ The template may need to be inverted
when cutting some bolt recesses.
■ Securely clamp jig to worktop.
■ The bolt recesses should be
approximately 20mm deep although
this will depend upon the thickness
of worktop.
■ Once one bolt recess is cut move jig
over to the remaining pencil lines and repeat.
■ Repeat the procedure for the male joint.
Best results are achieved when the
centre line of the bolt corresponds to
the centre line of the worktop. Clamp
jig securely to worktop.
Strengthening the Joint
If the joint between the worktops is not supported
underneath, after some time the joint may ‘sag’
and become misaligned; to reduce this the joint
should be reinforced with a loose tongue or
biscuit dowels. The biscuit jointing cutter set
Trend Ref. 342 can be used with a portable
router. The size of biscuit used should be No.
20.
Ref. BSC/20/100 (100 biscuits)
Ref. BSC/20/1000 (1000 biscuits)
A 650mm worktop should have at least 5
biscuits.
