Types of dovetails include through dovetails, half-blind dovetails, rabbeted half-blind dovetails, mitered-through
dovetails, blind dovetails, and mitered dovetails. Of these joints, the through, half-blind, and rabbeted half-blind are
the most common.
DOVETAIL AND BOX JOINT OVERVIEW
The dovetail joint is a traditional joint that is both strong and visually appealing. This joint has flared protrusions (tails)
that are cut into one board (drawer side) and protrusions with slanted sides (pins) that are cut in the other board
(drawer front or back). When the two pieces are joined, the tails and pins lock together mechanically, so that pulling
on the drawer front will pull the drawer side as well without the need for fasteners (screws, nails, etc.). Since the pins
and tails have a sufficient amount of surface, the joint is even made stronger by glue.
FAILURE TO FOLLOW THESE RULES MAY RESULT IN SERIOUS PERSONAL INJURY.
ADDITIONAL SAFETY RULES
1. READ AND FOLLOW ALL SAFETY INSTRUCTIONS in the instruction manual supplied with your router.
2. SECURE WORK. Be sure Dovetail Fixture/Jig and work is anchored securely to prevent movement.
3. BE SURE CORD SET IS FREE and will not hang up during routing operations.
4. KEEP HANDS CLEAR of cutter when motor is running to prevent personal injury.
5. MAINTAIN FIRM GRIP on router when starting motor to resist starting torque.
6. STAY ALERT and keep cutter free, clear of all foreign objects while motor is running.
7. BE SURE MOTOR HAS COMPLETELY STOPPED before removing router from Dovetail Fixture/Jig and setting
Dovetail Fixture/Jig down between operations.
8. NEVER REMOVE ROUTER MOTOR from router base while template guide and dovetail bit are installed. dovetail
bit may not fit through hole in template guide.
9. TIGHTEN TEMPLATE GUIDE LOCKNUT SECURELY.
10. SOME WOOD CONTAINS PRESERVATIVES WHICH CAN BE TOXIC. Take extra care to prevent inhalation and
skin contact when working with these materials. Request, and follow, any safety information available from your
material supplier.
REPLACEMENT PARTS
When servicing use only identical replacement parts.
16. AVOID UNINTENTIONAL STARTING. Do not carry a plugged-in tool with finger on switch. Be sure switch is off
when plugging in. Keep hands, body and clothing clear of blades, bits, cutters, etc. when plugging in the tool.
17. OUTDOOR USE EXTENSION CORDS. When tool is used outdoors, use only extension cords marked “Suitable
for use with outdoor appliances – store indoors when not in use.” If an extension cord is to be used outdoors it
must be marked with the suffix W-A or w following the cord type designation.

under the influence of medication, alcohol or drugs.
19. CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part that is damaged should be
carefully checked to determine that it will operate properly and perform its intended function. Check for alignment
of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect
its operation. A guard or other part that is damaged should be properly repaired or replaced by an authorized
service center unless otherwise indicated elsewhere in this instruction manual. Have defective switches replaced
by authorized service center. Do not use tool if switch does not turn it on and off.
