Leigh 16'' RTJ400 Router Table Dovetail Jig Leigh 16'' RTJ400 Router Table Dovetail Jig LEIGH RTJ400 Router Table Dovetail Jig Overview
Leigh 16'' RTJ400 Router Table Dovetail Jig

Woodworkers who prefer to use their routers mounted in a table will love the Leigh RTJ400. Unlike traditional dovetail jigs, the RTJ400 slides along the top of your router table, encouraging a comfortable upright posture, and eliminating the need to balance your router on the top of a narrow jig. It provides fast, accurate routing of through dovetails, half-blind dovetails and box joints. Like other Leigh jigs, the template for the RTJ400 is precision CNC machined from aircraft grade aluminum. Perfect joint fit is guaranteed and repeatable with the patented Leigh elliptical guide bushing.


Features:
  • Lets you create 5 sizes of through dovetails, 4 sizes of half-pitch through dovetails, 3 sizes of single pass half-blind dovetails, and 4 sizes of box joints (finger joints)
  • Also capable of routing angled dovetails and end-on-end dovetails (splices), both straight and angled
  • Makes precise joinery easy—just center the board on the template and guide the jig across the router table to rout the joints
  • One template makes all three types of joinery
  • Includes clearly illustrated, step-by-step user guide and a DVD with helpful how-to videos
  • Operation requires a 1-3/8'' Porter-Cable style insert ring to fit the Leigh eBush to your router table or router plate.

Very easy to use, great value.
I’ve been wanting to get a router table dovetail jig for a while. This one turned out to be very easy to use and I was able to complete the drawers I needed without any problem.

Beats my old jig
A lot easier to set up and use. Really nice clamps to hold the wood. It took me a while to wrap my head around their marking system for inside and outside settings.

Nice to stand and see the cuts from behind the saw dust. My shop vac and some duct tape keep the dust away.

This is an extremely well engineered dovetail jig with excellent instructions (and markings on the jig) for producing different dovetail joints. It is much more stable for making dovetail joints than the non-router table dovetail jigs.

A great router jug.
I haven't had a chance to use all its functions yet but half blind dovetails are a lot easier than on my ten-year-old standard jig. It is incredibly easy to assemble.instructins are clear and it is rugged. This is a must-have tool for any woodworker that wants to make beautiful joints.

Great tool... But warning to Bosch users.
Great concept.... Would buy again.
Can put an apprentice on building drawer boxes now without worries.
Warning... If you have Bosch router table be prepared to carve out an insert. Appears somewhere along the metric conversion way Bosch never cared about the old B&D / Porter Cable industry standard insert size.
Called Bosch about the situation. They treated me like I was from Mars.

RTJ400 Dovetail Jig
Well made dovetail jig with good instructions. The DVD that comes with the unit is a real joy, demonstrating how to use the jig. Comes with just about everything needed to make most dovetails, extra bits are available from Leigh. You'll need the table insert for a Porter Cable Bushing.
I would buy another if I had to do it over again.

This is a very well built jig, and easy to use.
After a few trial and error pieces, I got it dialed in and it works great. It's also very easy to set up and quick to use. Great product .

truly cool
I had used the old fashioned dove tail template, and it worked, but was hard to adjust. Also, one time the bit got loose and ruined some drawers. This worked the first time. I was amazed on how accurate the adjustments could be. I only did box joints the first time, but now I am moving on to dove tails. a truly great system.

It has received good product reviews and is priced reasonable.
George` R on May 9, 2016
Liked the fact that the jig is on a router table - easier to use than balancing router on a template. Also adjustments and set up look to be easier.

CAN BE USED WITH ROUTER TABLE
RICHARD P on Mar 13, 2016
I really like the idea of keeping the wood flat on the table and just guiding it through, with the other types of dovetail jigs you have to make sure and not tip the router at all or you'll mess up the cut.
shannon w on Feb 24, 2016
The jig is very versatile and user friendly. I'm particularly excited about the adjustable guide bushing that will ease the tedious setup time to get a perfect tight joint. Looking forward to my first use!

I have the D4-24 for many years now but if I need a quick project the D4 is too big and cumbersome so I hope to use this for small projects

I wanted to cut dovetails and box joints on my router table. This jig comes highly recommended and has some videos on YouTube showing it in action. This will save me setup time with hand-held jigs and space which is critical in a small shop.

i have a bench dog cast iron table top and bought this jig. Is there an insert available to fit this jig?
James R on Mar 15, 2017
BEST ANSWER: There is, #40-015, but Rockler curiously stopped making it when it bought BenchDog, and it is now not available, making it impossible to use the RTJ400 on the cast iron BenchDog router table without it. It doesn't seem like it would be a big deal for Rockler to resume making that part.
I just bought the rtj400 and have a craftsman router table, which insert would I need? Do you sell just router table tops that come with the correct plate. The craftsman table might be to small to use the jig with.
Robert W on Nov 10, 2016
I have the rockler pro phenolic router table. Do I need the insert with the 1- 1/4"opening to use the rtj400 jig?
Sid A on Sep 28, 2015
BEST ANSWER: Yes you will need the 1-1/4" insert. Be careful what you get because there are two sizes. One in 4" and the other is 4-3/8"
is there an insert ring accessory for the Leigh RTJ400 that will fit a bosch RA1711 router table?
Bill B on Sep 21, 2015
BEST ANSWER: Yes there is. Contact Leigh customer service. It costs 8 bucks.
where can i find a router table insert that will accept a 1/3/8 portacable bushing? I have a wood teck router table and lift.
Don Wooten on Jan 19, 2016
BEST ANSWER: I have a JessEm lift and plate which has an insert that works great for the E-Bushings used on the RTJ400. This insert is part of a 4pc insert ring accessory kit and was not included in the rings sent with the plate.
is there a vidio of the ig in action?
terry t on Aug 15, 2017
BEST ANSWER: Yes there is - it is included with the jig. I have been using the jig on a couple of box projects and it has worked very well.
