Parts needed -

• Template A (through / box)

• 10.79mm Straight cutter (pins)

Cut dovetails first - dovetail cutter, ¾" guide bush used

1)

 Attach comb A with the straight fingers (tails) at the 

front of the jig, see fig 01 & level the comb by placing 

a 15-20mm thick x 150mm - 200mm wide x 200mm -

2)

 Move the magnetic extraction then use the hex key 

provided to move the side stop to the left, see fig 03-04-

05. Load in vertically the first board on the left of the jig 

pushing up to the underside of the comb & centralising 

to the fingers, see fig 06-07.

3)

 Ensure that the material markers on the comb are 

centralised to the top of the board & look equal along the 

length, see fig 08.

4)

 Slide the side stop towards the right to make contact 

with the side of the board, see fig 09 & lock in place.

5)

 Use the opposing board to mark a cutter depth set 

line on the material, see fig 10 then plunge the dovetail 

cutter down through the fingers in front of the board so 

that the tip of the cutter just meets the marked line, see 

fig 11.
