Leigh Super 18'' Dovetail Jig  Zoom

Leigh Super 18'' Dovetail Jig

Item #: 38921


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.

Want to pamper yourself with a precision machine but can't afford a new Beemer? Buy a Leigh Superjig. Want to learn/improve workshop skills but can't find a mentor? Read the Superjig manual. Want to develop an addiction but don't want to go to jail? Try dovetailing.PBS would have you believe that dovetailing is an ancient and mystical art practiced by Amish craftsmen using handsaws and chisels. What a delight to discover dovetailing jigs for those of us unable to spend 30 minutes on one pin and tail. Several favorable on-line reviews of the Leigh Superjig and its manual convinced me to buy this rather expensive piece of equipment. It was worth it. The manual is an education in itself and, unlike documentation for electronic gizmos, appears to have been written by someone whose first language is English. Read it carefully and repeatedly there's a lot of valuable information in there.The jig is cleverly designed and impressively constructed. Since it is not purpose built for just one type of dovetail it does entail some patience and attention during the crucial set up and adjustment stage which will require two things: 1) some sacrificial pieces of wood the same thickness as will be used for the dovetails 2) a careful reading of the manual. The jig is most versatile with a router that can accept Lieigh's proprietary bushing. Some routers will accept the bushing, some will need an adaptor and some will just have to be replaced, unless you're willing to use a generic bushing and omit some of the more exotic dovetail options. I had to buy a new router which added to the cost (and the fun) but have yet to try any of the exotic dovetailing.Leigh sells an accessory Vacuum Router Support that provides much needed additional support for the router and a port for your shop vac to minimize the mess. It should probably be considered essential rather than optional.My first project was a pine box for the new router. It was good practice for setting up and creating through dovetails just one of the many types of dovetails the jig can make. I wasted a bit of pine learning how to set up and adjust the jig but that's what pine's for. The second project was a pine box for the Superjig itself. This time using half blind dovetails and, once again, chewing up some pine during the set-up/adjustment process.The third project was a cherry and maple cabinet for a stereo receiver. It used half blind dovetails again but the jig had to be re set and adjusted due to using thinner wood than the previous half blind dovetails. In preparation for this I had planed some sacrificial set-up pine the same thickness as the cherry and maple. So far the process and results of creating through and half blind dovetails has been quite rewarding and well worth the time and money invested.

Kevin W from Chesterfield, VA Posted July 20, 2009
It's essentially a complicated piece of equipment with very thought out instructions that really cover everything and leave few, if any questions about how to use it. Leigh really thought out how to make something that is complex in theory become simple to use in practice. Don't expect to get it out of the box and start cutting perfect joinery right away. Going through the setup process helps to understand how it works and after some fine tuning, it does cut great dovetails. I cannot emphasize enough how good the instructions are - if you go through them once thoroughly, everything should make sense; twice and it should be second nature. The instructions and on-line materials are really a great resource that can be referred back to along the way as you get more and more time using the jig. It may not have some of the quailty characteristics of the D4R, but it's not a D4R now is it, nor does it cost as much. The modifications made to the Super series maintain accuracy but improve cost feasibility - that's why I got the Super18 and not the D4R in the first place.

Jason C from Canadian, TX Posted February 8, 2008
I am very happy with my Leigh dovetail jig. I set the jig up in about 45 min. The instructions were very easy to understand and I was cutting dovetails in no time. I would highly recommend this jig.
