SETTING UP
Letterbox
The CRB7 is fitted with 5/16” (8mm) diameter
guide rods (5 & 6).
If the router base rod drillings are smaller, fit
the 9/32” (7mm) guide rods.
2. Loosen the Lock Nuts
Using 1 x 1/2” (13mm) spanner, slightly loosen
fixed rod nut (6E) and micro adjuster nut (4B).
Position the router in front of the CRB7.
Align the router base rod drilling (A) with
Adjuster Rod (5).
IMPORTANT
IT IS NOT ESSENTIAL TO CENTER THE
ROUTER CUTTER PRECISELY WITHIN
THE CRB7’S LETTERBOX FOR ANY
OPERATION.

Check that the router cutter will safely align
within the letterbox cross hatch area.
IF IT WILL, GO TO STEP 7.
IF IT WILL NOT, GO TO STEP 5.
Loosen the M5 nut (5B) using a 5/16” spanner.
Move the adjuster rod (5) to the other crank
plate drilling (5E2).
Replace washers and nuts and tighten.
For further adjustment fit the rods in the other
crank plate drillings (5E2 & 6E2).
Flip cranked adjuster rod (5) to its outer
position.

Hold Still
Align fixed rod (6) with the router base rod
drilling (B), so that both rods are aligned.
Slide the router onto both rods until it stops at
the Bridge end of the CRB7 assembly.
Using 2 x 1/2” (13mm) open ended spanners,
tighten both fixed rod nuts.
Tip: Using two spanners when tightening the
fixed rod nuts will prevent the rod setting being
disturbed.
Both guide rod positions are now set.
Important - Before attempting any
machining pass:
Ensure that the router is securely fitted to the
CRB7 by checking ALL CRB7 fixings, including
router base wing bolts and micro adjuster lock
nut.
IMPORTANT
Follow the below steps in order:
1. Tighten router base wing bolt (A).
2. Finger-tighten fixed rod nut (6E).
3. Tighten router base wing bolt (B).

Tip: Positioning the router base Wing Bolts
towards the bridge end of the CRB7 will increase
micro adjuster accuracy.
Using the index markings
The micro adjuster and bridge have
corresponding red index lines. (1A & 4A)
1 x Micro adjuster rotation = 5/100” (1.25mm).
4 x Rotations = 3/16” (5mm).
Removing the slack from the adjuster
thread.
• Loosen both router base wing bolts and turn
the adjuster (4) in the desired direction to
engage the thread.
• Rotate until index markings (1A & 4A) align.
• Re-tighten the wing bolt on the adjuster guide
rod.
• Should the router cutter need to be adjusted
in the opposite direction repeat the above
step.
Once happy with the rule location:
• Ensure that the baseplate (2) is clean.
• Peel off the self adhesive backing paper.
• Stick in position.
THE LOCK BARS
Use the lock bars (18) to help tighten and
loosed the guide rods.

THE MICRO ADJUSTER
• Plunge the router cutter to a level just above
the workpiece and lock in position.
• Loosen the router base wing bolt (I6) on the
fixed guide rod (6).
• Lock the router base wing bolt (I5) on the
adjuster guide rod (5).
• Rotate the micro adjuster (4) to move the
router and cutter into position.
• Lock the adjustment in position by tightening
the adjuster nut (4B) against the bridge (1).

Many routers are manufactured with a cast
index line (11A).
• If the router has no index line, draw one
on the base using a fine tip marker pen.

With the router fitted to the CRB7:
• Position the rule (11) along the edge of the
router base.
A measurement can then be taken as the router
is moved.

• Fit the cutter to the router and re-fit the
router onto the CRB7.
• Position the CRB7 with a mortise pillar (10)
either side of the work piece.
• Rotate the CRB7 clockwise until both mortise
pillars contact the sides of the workpiece.
• Adjust the cutter position to the mortise
markings, use the micro adjuster if required.
• Lock the router position on both guides rods
using the router wing bolts.
For a deep rebate, several light cutting
passes may be preferred.
Before use, check that the router is firmly
secured to the CRB.

Guide
• Fix the clamp guide (J) on the workpiece.
• Butt the bridge end of the CRB7 up against
the clamp guide.
• Slide the router along the guide rods to

• Slide the anti-tilt leg (8) into the bridge
from the underside.
• Tighten the bridge pinch bolt (3) to lock it in
position.
• Slide the router onto the CRB7 rods and lock
in position using the wing bolts (I)
• Rest the CRB7 and router on the work piece
(M), then release the bridge pinchbolt (3) to
set the anti-tilt Leg depth.
• Lock the anti-tilt Leg in position.
Before routing, check that the bench
surrounding the work piece is smooth, even
and clear of obstacles.
Anti-Tilt Support
The Anti tilt leg is a two part assembly.
Max. Support height = 3 1/8” (80mm)
Min. support height = 5/16” (8mm)
If the mortise is positioned at the end of
the work piece, clamp extended battens (L)
to either side.

When cutting the mortise, ensure an even
pressure is maintained between the
mortise pillars and workpiece.
To avoid splitting the batten, pilot drill and
screw into position by hand.
• Fit the CRB7 to the router.
• Check that the batten (N) slides into the
first groove and moves smoothly along its
length.
• Set the required distance between the router
cutter and batten.
• Use the micro adjuster (4) to finely adjust cutter
position if required.
• Lock the router in position using the router base
wing bolts (I)
The second groove can now be routed.
• Slot the batten into the second groove to rout
the 3rd groove.

(160mm) in timber or solid plastic i.e. nylon or
polyethylene.
Note: The batten profile should copy the size and
shape of the router cutter.
• Test the batten in a sample groove to ensure a
good but not over-tight fit.
• Rout the first groove into the workpiece. Use a
clamp guide or side fence.
• Using 3 x No.6 woodscrews (12) fix the batten to
the underside of the baseplate via hole E & C.

• Slide the router onto the CRB7 guide rods.
• Position the router at the opposite end from
the Bridge (1).
• Lock the router in position using the wing
bolts (I)
The router cutter should just sit safely
within the baseplate ‘letterbox’.
• Fit the offset handle (7) into the bridge and
lock in position using the bridge pinchbolt (3).
Ensure that the CRB7 handle end remains
over the work piece.
