Bridge City DJ-3
Universal Drilling Jig
English Version
Congratulations on your new DJ-3 Drilling
Jig!
READ FIRST
This manual is designed to provide you with a
better understanding of your new drilling jig,
how to operate and maintain it.
Please read the manual carefully. The manual
also includes our warranty and important safety
information. As with all tools, please ensure to
take all necessary safety precautions to
prevent any accidents! Always remember,
safety first!
SAFETY FIRST
When working with the DJ-3 Drilling Jig always
remember to:
• Ensure that everything is properly secured
before drilling
• Wear eye protection when drilling
• Work in a clean and safe environment
• Maintain your tools!
Overview
You will soon learn that the DJ-3 Universal
Drilling Jig can easily be thought of as a drill
press in a box. It offers a legitimate answer to
the drilling needs of many customers without
the hassles of complex fixtures and intricate
setups.
However, the DJ-3 Universal Drilling Jig is
meant to be used in conjunction with a
powered hand drill, a palm brace, or
eggbeater-style hand drill. Drill and drill bits are
NOT INCLUDED with the DJ-3 Drilling Jig, so
please ensure that you have all the proper
tools necessary for the task.
In order to drill holes accurately and safely,
having your workpiece in a vice or clamped to
a sturdy bench is strongly recommended. The
DJ-3 can then be clamped to your material with
an appropriately sized clamp.

As seen in the chart above, there are an
assortment of sized bushings provided with the
DJ-3 Drilling Jig. Please choose the
appropriate bushing and corresponding drill bit
to ensure the accurate results.
Install the bushings as following steps (Fig. 2):
1) To install the bushing, start by extracting
the hex wrench that is magnetically stored
within the left outrigger body.
2) Using the hex wrench, loosen the two
screws (Screw A) on the both ends of the
DJ-3 body. Then remove the two screws
(Screw B) at the top of the DJ-3 body. Set
these screws safely aside for now.
3) Insert the desired bushing into the Drilling
Jig Body. Make sure to align the notches in
the bushing with the body.
4) Reinstall both Screw B and Screw A, and
tighten properly.
Note: In the below illustration (Fig. 2), only one
Screw A and Screw B are shown for simplicity
purposes. There is one more Screw A and B on
the mirrored side of the DJ-3 body.

Positioning the DJ-3
When setting up the DJ-3, it can be utilized
in two (2) drilling configurations: Centered
and Off-Centered drilling. Please refer to the
appropriate sections for setting up the DJ-3
accordingly.
1. Centering the DJ-3 (Fig. 3)
Start off by clamping the stock to a bench or in
a vise. Loosen the Arm Locking Knobs (D) and
pull the left and right outriggers jaws
(champagne colour) apart (the distance of the
jaws must be larger than the width of the stock).

Left Outrigger
As shown in Fig. 3, position the drilling jig on
top of the stock and close the outriggers jaws
so that the jaws make contact with both faces
of the stock. Once positioned into place, tighten
the Arm Locking Knob (D) to set the position.
The drilling jig should be precisely centered
with the stock and ready to be drilled.

2. Off Centering (Fig. 4)
Similar to centered drilling, start off by clamping
the stock to a bench or in a vise. Loosen the
Arm Locking Knobs (D) and pull the left and
right outriggers jaws (champagne colour) apart
(the distance of the jaws must be larger than
the width of the stock).
To set the offset, loosen the Adjustable Jaw
Lock Knobs (E). From there, you can slide the
Adjustable Jaw to the desired position. There
