Leigh Super 12'' Dovetail Jig
Extraordinary joint making capability at an exceptional price point! Cut variably spaced Through & Half-blind dovetails easily and accurately. Infinitely adjustable one-piece fingers are easily positioned for any joint pattern, and you are always guaranteed a half pin at each edge of the joint. Rout half-blind pin boards and tail boards at the same time. The finger assembly can also produce two sizes of box joints, 5/16" and 5/8". Adjustments for fit can be made in increments of .002". You can even install the included crosscut fence and the dovetail finger assembly becomes a sliding dovetail template. Available in three widths: 12", 18" and 24" to satisfy the needs of every woodworker and every budget.

The amazing joint making capability of Super Jigs is due in part to the revolutionary new Leigh E Bush (patent pending). A simple twist of the E Bush changes it's active diameter which in turn changes the fit of finger joints and half-blind dovetails.

  • Easy to use cam action clamps
  • Aluminum clamp bars
  • Non-slip material on every clamping surface
  • Infinitely variable spacing

Don’t waste time and money on any other jig. Set this up and my sample was good to make dovetail box my second box was close to perfect. I tried the rocker jig and chased the adjustments for a whole day.

Wow, love my new Leigh dovetail jig!
This jig is amazing. There is a definite learning curve and I used up some wood in the process, but it was worth it for the results I get now. I had been using a cheaper non-adjustable jig and had accepted that cutting dovetails meant being covered in wood shavings. Once I got the Leigh and the optional VRS dust collector, I realized that was unnecessary. This thing gets about 99.9% of the shavings. This is a whole different level of engineering. Any future jigs I buy will have the Leigh name.

Best Dovetail Jig on the market
I love this Jig. Great quality and precision. Makes the best quality joints super fast. Allows for all the flexibility you could ask for and the adjustment with the router guide allows for as tight or as loose of a joint as you need. The only issue is that when I unpackaged the product the instructional DVD was cracked down the middle. The instruction book that comes with it is very detailed and easy to follow, but when you pay $300 for a product you would like for everything to be intact.

Makes perfect bee box joints
Love it . I did make a few adjustments and changes but it cuts my bee box box joints perfect. 30 hives strong this season thanks to the Leigh.
Making our own hives saves us bundles. Bee happy!

Buy It!!!
It is well worth the higher cost. It is the only tool I have ever bought that worked... right out of the box. It takes a little while to set it up. The first test run I did for the through dovetails worked like a charm. Amazingly accurate. My only complaint was that I didn't buy the larger one. The CD and manual are very detailed and helpful.

From what I have been able to research it is not clear to me how you do the 5/16 finger joint?
RANDY A on Dec 18, 2015
I have a Festool MFK 700. Will this router work - is it powerful enough?
Ennis O on Feb 26, 2017
BEST ANSWER: I looked at the Festool MFK 700 online. I believe that you should have no problem because the router doesn't have to fit the jig, the bit followers the fingers of the jig. So, YES!
what router is being used in the instructional video for this jig? The skil router that I had would not work on this jig. Can you recommend a router?
Gary P on Jan 11, 2016
BEST ANSWER: I had a Hitachi router 3-1/4 HP i used but it was entirely too large for this operation. I found a 2 hp rigid at works great and is well balanced. I'm sure there others that will work as well. You will have to use the bit guide that comes with the Leigh jig and it has to fit the base plate of your router. Most routers these days will allow for the guide but its possible;e you'll have to purchase a separate base.
what is the thickest stock that may be used in this jig?
A shopper on Apr 7, 2015
for through dovetail the maximal thickness is 13/16" or 20 mm. For half blind dovetails the maximal thickness is 1" or 26 mm.
Does this jig allow you to make a running dovetail? in other words, if I want to make a 36" long dovetail can this jig be moved along the board and self index on the last dovetail (i.e., much like a dowel pin jig for shelving) so that I can effectively make a 36" running dovetail with a 12" wide jig or does it have end caps that limit movement along the board? If this jig does not allow for what I am trying to accomplish, can you recommend an alternative jig?
Charlie C on Feb 21, 2018
BEST ANSWER: Yes. chapter 13 in the manual has instructions for what they call sliding dovetails.
Where can I buy Half-blind bridge piece material for the Leigh Super Jig?
LJ G on Aug 9, 2015
BEST ANSWER: The jig comes with three 12" pieces that can be inserted whole to perform sliding dovetails or cut to use as spacers. I'm not sure where to buy extra but the three pieces seem like you'd get quite a few spacers out of them.
can bits with a 1/4" shank be used?
Rich N on Dec 30, 2017
BEST ANSWER: Bits supplied with this are all 1/4" and the adapter for i/2' collet is supplied
Can you do 4 pieces at once on this jig?? ie: a front and left side on the left and the back and right
side on the right side of the jig?
