Assembling of FK
The whole system of the FK jig is based on the use of three steel stops, which are inserted into various holes
in order to attain the precise manufacture of the outer and inner part of the joint. The holes for the steel stops
are indicated with letters (fig. 1).
– outer part of 45° joint
A... TWO HOLES
– outer part of 90° joint
B... TWO HOLES
– inner part of 90° and 45° joint
C... FOUR HOLES
– fixing holes for clumps
D... FOUR HOLES
– radius finishing of corners (R 8,2)
E... THREE HOLES
– 45° finishing of corners
F... TWO HOLES
– inner part of 45° joint
G... ONE HOLE
– inner part of 90° joint (worktop 600mm)
H... ONE HOLE
The steel stops are furnished with rubber rings which prevent the stops from dropping out of the holes. Place
the metal stop into the hole using the pin with the rubber ring, so that it is completely inserted. If the metal
stops are difficult to insert, lubricate the rubber rings with oil. Before using always ensure that the stops are
completely inserted into the holes. Before using check that the stops are not leaning against the work table.
Setting of cutting axis and copying edge
The cutting line is always shifted by 9mm (FK650) resp.8,5mm (FK651) from the copying edge of the jig upon
use of a guide bush dia.30mm and a router bit dia.12mm (FK650) resp. 12,7mm (FK651) (fig. 5). To obtain a
precise joint don't use resharpened tool (diminution of cutting diameter).
Cutting of 90° joints
The working procedure is demonstrated on a right-handed 90° joint (fig. 4)
- Always cut the joint so that the metal stops touch the postform edges of the kitchen worktop.
- Always shape in the direction towards the postform edge and out, never the opposite way. This procedure
attains a perfect joint.
- Should remains of the paper base be left on the underside of the kitchen worktop after the routing, remove
them with sandpaper.
- Don't remove the tool from the jig groove until the tool is completely stopped after routing, you prevent the
tool damage.
Cutting of inner part of joint, worktop width 500-550- 600-616 and 650 mm
Insert two metal stops into the C holes and according to your worktop width one into the respective H hole
from the underside of the jig. The numbers at the letter H are for the worktop width. Place FK on the kitchen
worktop F1 from the facing side (fig. 6).
Ensure that all stops 1, 2 and 3 are touching the edge of the worktop. Now tighten FK to the kitchen worktop
and working table using the clamps and check that the clamps do not hinder the movement of the router in
the jig groove and that they are well tightened. Set the cutting depth on the router. Insert the router by the
guide bush into the groove of the jig and begin to cut the joint on multiple pass from left to right; copying the
edge of the jig indicated by the arrows (fig. 8). If you don't cut all the worktop thickness at one cut, you can
use for rough cutting the opposite edge the jig groove and so you will have ca. 1,5 – 7mm of material left for
the final cutting. Now use the right edge of the groove (fig. 8) and make the final clean cut. Keep the right
direction of routing – the tool must cut the edge counter-rotational.
