Product Description

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.Optional accessory kit also available. See the AC 12 Accessory Kit.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.Standard Equipment:1/2" 8° dovetail bit1/2" 14° dovetail bit5/16" straight bit1/2" to 8mm collet reducerSliding dovetail fenceSquare drive screwdriverCam action speed clampsFully illustrated User GuideInstructional DVDSpacerLeigh E BushHalf-blind bridge piece materialOther features include:Easy to use cam action clampsAluminum clamp barsNon-slip material on every clamping surfaceInfinitely variable spacing

This is my review of the Leigh Super Jig 12" dovetail jig. The price I paid, nearly $300 after taxes (265 list on amazon), was on the high end of the models I had considered purchasing. What did I get over similar models I had considered? First, solid construction. The guides and body are aluminum with the cam levers some kind of ABS plastic. Second, flexibility. The jig is capable of doing through dovetails (two pass), half blind dovetails (both two pass and single pass), rabbeted half-blind dovetail, sliding dovetail, asymmetric dovetails, decorative/inlaid dovetails and box joints. Third, superb documentation. The tool actually ships with both a how-to-dvd and a spiral bound, nearly eighty page manual on how to cut the different types of dovetail joints the jig is capable of forming. The jig is made in Canada.Cons. Let's start with the negatives and get that out of the way. Price is obviously on the high end. The router bits use a bizarre 80mm shaft size which are neither the 1/4" or 1/2" standard shaft sizes, an 80-mm to 1/2" collett adapter is provided. Additional bits are available from Leigh or Whiteside. I have not tried the Whiteside "Leigh" bits to see if they perform better. For half-blind dovetails other than 7/16" depth, additional bits will need to be purchased, the same is true for single-pass half-blind dovetails other than 9/32" depth.In the Box. Dovetail jig parts. Three router bits, two dovetail and one straight bit. DVD and spiral bound documentation. Quick reference guide. Collet adapter. Variable spaced guide bushing. Screwdriver for adjusting the jig fingers.Some Assembly Required. In addition to the parts in the box, you will need four pieces of wood as follows: 3/4" x (at least) 5" x (at least) 26" for mounting the jig body (or you can mount it in your workbench directly); (2) boards approximately 3/4" x 6" x 8" cut square; and last, 3/4" x 6" x 11" backing board for finger support during cutting. Assembly consists of attaching the stops, cams and fingers onto the main aluminum jig body and aligning the lower stops so they are parallel to the upper stops. This step is important in order to get the two mated pieces to be flush to each other. Rather than use the two short boards, I suggest using a square (if you have one) on top of the board to perform this procedure. Not only is it easier, the square is bound to be more accurate getting the two stops lined up correctly. See the photo I have attached.Documentation. Unlike most other tool documentations I have seen where half of the pages list all the possible ways you could do yourself in with the tool, the Leigh documentation is actually useful and explains in great detail, with illustrations how to set up and operate the jig to perform the different dovetail joints it is capable of cutting. In addition, there are explanations on how to correct different problems (over/under cut, too loose, too tight, etc) and in most cases it actually explains what causes the problem in question. It closes of with a section on hints jig and router hints (such as for certain dovetail cuts, doing a climb cut first to avoid tearouts). The manual even manages to make subtle digs at other jigs that can't do variable spacing ("Why rout single pass?...or if you are making a lot of drawer boxes and are not so concerned with the traditional hand cut look"). For those who'd rather watch than read, the included DVD repeats most of the written documentation.Operation. As I had mentioned in the "Cons" section earlier, the jig uses specialized "Leigh" bits with an odd 80mm shaft size. This means you cannot use these bits if you only have a 1/4" diameter router collet. For 1/2" router collets, an adapter is provided. Insert the adapter collet, bit and the variable spaced Leigh guide bushing into the router. Align an tighten the guide bushing to the correct orientation. Jig setup depends on the type of dovetail you wish to cut. As an example, to cut through dovetails: insert backer board into top cam, insert tail board; flip the guide fingers into pin mode and adjust the guide fingers to their desired positions (taking care that the ends are covered by half pins); flip the pins into tail mode, lower and tighten; adjust bit depth by lowering or raising the router bit to a pencil line scribed to the same thickness as the tail piece; adjust finger position to "all"; route; remove tail board, insert pin board, flip the guide fingers into pin mode, change router bit to the straight bit, adjust bit depth, adjust finger position to 1/2" (depends on the bit being used), route. Some initial adjustment to get tightness correct, is necessary when cutting the pins. A page is provided in the manual for you to write the calibrated setting down. In actual use, you'd be cutting all the tail and pin board together so the bit only needs to be replaced once during operation. Variable spaced half-blinds require cutting up the provided plastic guide piece to fit between the fingers. If you are like me and can't cut jack with a hacksaw, cut the plastic guide piece a little bit longer then sand it down to the correct size.Flexibility. Besides all the different types of cuts the jig can do, through and two-pass half blinds can have variable spacing. You can now be sure your cuts end in proper half-pins without needing to adjust your workpiece size. Single-pass half blind and box cuts use fixed spacing. I believe (but have not tested so don't quote me on it) the two pass dovetail cuts allow two different wood depths. Bit depth, finger position, guide bush position all control the depth and tightness of the cut. The guide bush solution is unique to Leigh. Of the jigs I looked at within what I wanted to spend, the Leigh jig was the most flexible and capable.Upgrades. Additional dovetail bits can be purchased from Leigh or Whiteside. An upcut spiral bit which is supposed to cut faster and cleaner is available. Vacuum attachment (I have no intention of getting). Upgrading to the bigger 18" or 24" models makes additional finger and other fancy templates available (those models are more than what I want to spend).Other jigs I looked at according to order considered. Keller journeyman (phenolic template, minimal setup, only does thru dovetail, add clamp kit and almost the same price as the Leigh). Rockler complete (phenolic templates, not as versatile, add 100 more to get the Leigh). Porter cable 4212 (negative reviews turned me off).Final word. I am by no means an experience woodworker and this is the first time I have attempted dovetail joints. If the tool helps me make them successfully, then I am happy with and so I'm giving it a five-star recommendation. I've attached photos of my FIRST attempts. Both cuts need a little more depth so they are slightly protruding but it's an easy adjustment to make. I'm confident that with a few more cuts, I will get both perfect.One last comment. The photo on this product page is for the accessory attachment (as of 12/13) and not for the jig itself.

4.0 out of 5 stars Very precise tool
Reviewed in the United States on December 12, 2021
I previously had a P&C dovetail jig and the Leigh jig is much better. The only reason I knocked off a star is that for some reason Leigh decided to use plastic rather than metal for critical stops/guides for the workpiece and I can see it is going to wear down over time. With dovetail joints, 1/64" is the minimum precision you need to shoot for and anything that throws off the ability to get workpieces lined up exactly right will tend to make sloppy joints, so all metal parts would be better.

Pros:
- Very good instructions. Crystal clear. I wish all manufacturers had instructions like these.
- Flexible dovetail layout options, which is why I bought this tool
- Precise, tight joints

Cons:
- Plastic parts in critical places
- Stamped sheet metal. Could be a higher gauge metal for a more robust tool

Hint - the key to making precise joints is getting the depth of the pins and tails exact. Ignore the instructions where they say to use a pencil line, instead use the work piece to set the depth. I put the router on the bench, with plate up, put the tails board on top of the plate, put another 1/2" (exact) board to account for thickness of the template, and then use a straight edge to exactly set the depth of the bit for the pins or tails. Doing this, it should be within 1/128" of an inch. If you eyeball it with a pencil line it will be within 1/32" at best. See the photo.
