TREND HINGE/JIG - Recess Length Adjustment; Recess Depth Adjustment

-9-
HINGE JIG & H/JIG/A
Lay the jig onto a flat surface e.g. the edge of the
door. The procedure for setting the position of
each hinge is as follows:
I Slacken block retaining screw of upper aperture
block.
I Measure required position of hinge using tape
measure.
I Slide block to required position.
I Tighten block retaining screw.
The top aperture has no upper block as it is fixed
at 150mm (6") position from the top of the door.
If only two hinges are used, then only the top and
bottom apertures of the jig will be used.
Setting the Length of the Recess
The length of the recess for the hinge is governed
by the lower aperture blocks which can be
adjusted for hinges of length 75mm to 105mm.
The 4mm spacer gauge is used to give the
necessary offset. The procedure is as follows for
each of the three apertures:-
I Place one hinge lengthways into the aperture.
I Slacken block retaining screw of lower aperture
block.
I Place spacer gauge between hinge and upper
aperture block.
I Slide lower block up to hinge.
I Tighten block retaining screw.

Ensure working position is comfortable,
especially when setting up the jig and
routing a hinge recess in a door.
Setting the Depth of the Recess
The depth of the recess must be the same
thickness as the hinge or slightly deeper. Most
routers are fitted with a depth stop to limit the
depth of plunge of the router. Refer to your
router’s instruction manual for particular details on
using the depth stop. The depth of the recess for
the hinge is set as follows:
I Release depth gauge on the router.
I Place jig onto the edge of the door.
I Place router onto jig and locate guide bush into
one of the apertures of the jig.
I Plunge cutter through aperture until it touches
the edge of the door.
I Lock the router’s carriage in this position.
I Move depth gauge up by the thickness of the
hinge by:
1. Either using the depth gauge
measurement/dial
or
2. Placing a leaf of the hinge between the
depth gauge and the stop.
I Lock off depth stop and remove hinge.
I Check the depth of the cutter is correct by first
fully plunging the router and locking the plunge
mechanism. Invert the router and place the jig
over the guide bush, now check that the cutter
protrudes past the template the same distance
as the thickness of the hinge.
Double check all settings, ensure all screws are
tight. Setting up is complete.
