NB if working in very hard wood a stock removal cut may

be wise, this is done by running a 6mm cutter through

the slot first, with the cut depth a little less than the

required dovetail cut, see fig 13-14.

Dovetail tenon cut

1) With the comb in the same position load in & clamp

the tenon board into the jig in the vertical position

ensuring that the board is against the side stop on the

right & the board is up against the underside of the

comb, see fig 15. NB a comb support board may help

keep the comb from flexing if a large heavy router is

being used.

Fig 15-16-17

2) Use the smaller (3.2mm) end of the setting gauge (H)

to align the comb slot to the edge of the board ensuring

that both ends of the board are set the same, see fig 16-

17. No cut will be made at this stage.

Fig 18-19-20-21

3) To set the comb to

make the first cut move

the comb towards the

front of the jig by first

unlocking the comb lock

knobs & then turn both

comb adjuster knobs one

full turn anticlockwise.

Making a pen mark on the

adjuster knob may help

with this, see fig 18-19-20-21.

4) With the cutter set at the same depth as when cutting

the dovetail slot (approx ⅔ material thickness) position

the router at the left side of the comb, cutting from left

to right in a slow continuous motion, DO NOT LIFT THE

ROUTER AT ANY TIME DURING A CUT, see fig 22-23.

With the board the same end up flip the board & cut

the other side, see fig 24-25-26. Position the magnetic

extraction to the left or you may prefer to use the router's

extraction for best extraction results on this cut, see fig

27. Try for fit, see fig 28.

More passes may be required depending on board

thickness. To remove more material simply adjust the

comb towards the front of the jig as in step 3, see fig 29.

Trouble shooting -

• Gap one end of the dovetail - comb not sat flat on the

board, see fig 30.

• Joint too tight - remove more material by moving

comb very slightly forwards.

• Joint too loose - move comb slightly backwards & recut

new board.

• Joint not square on board - pencil line not marked

square, comb slot set gauge not used.

• Gaps on shoulders / tenon top - cutter depth not the

same for both cuts , comb not sat flat on board, see fig

31.
