With a simple indexed angle setting system, heavy duty hold-down clamps and a smooth sliding design, it makes tapered cuts fast, easy and more precise. Perfect for chair legs, table legs and more. Jig fits snug in any standard 3/8" x 3/4" miter slot and features a large, ergonomic handle for smooth push-action performance throughout the cut. Plus, with the miter bar removed it doubles as a stable straight line ripping jig. This jig works with table saws on which the left edge of the right miter slot is 3-3/4” to 4-3/8” from the blade or 5” to 5-5/8” from the blade.

Features:
  • Includes 36" miter bar
  • Indexing marks make angle setting easy — each mark represents 1° of taper
  • Dual tape measures provide convenient reference and also help set angles
  • Two wide-body hold down clamps prevent stock from drifting dangerously from your fence
  • Clamps have non-marring rubber caps for enhanced grip
  • Three adhesive strips run across the jig to help stabilize your workpiece
  • With taper angle zeroed out, jig works great to rip straight edges on rough lumber

Convenience makes this a winner!
You could make one of the these on your own, but buying this especially when its on sale, is just more convenient. It comes with all the necessary components and its just about ready to go right out of the box. There are a few simple items to set up, but they are pretty easy and painless. To put it plainly, once you get this home, you can be using it in a few minutes and that's worth a lot.

Here is my one complaint. The adjustment screws on the miter bar, while easy to adjust can move in or out with use. I would suggest using some loctite on them to keep them better set.

For me this was definitely worth purchasing.

Buy it!
it works great, and not just for tapers.
The only thing that was disappointing is it didn't work with our table saw. The guide didn't fit in our saw, we have a cheap Kmart saw. But we had access to a commercial saw and it worked perfectly.

I have a ridgid contractors saw, 22" front to back and only about 9" to the blade. I don't know if I can make this work. Anybody have a similar size saw with this jig ?
A shopper on Aug 18, 2015
What is the maximum length that you can taper with the jig?
Jake V on Feb 21, 2016
BEST ANSWER: Edit to previous answer; this is assuming that you have a full size cabinet saw. I you are working with a small portable contractors saw the length of the board should be drastically reduced. I don't believe that I would try to push anything through one of those longer than 2-3" over the length of the jig. Just my opinion though....
Does this jig work with DeWalt job site saws?
Dan S on May 3, 2016
BEST ANSWER: The miter bar on this product is 3/4" wide by 3/8" thick. I am not sure what size miter slot the DeWalt has.
This item also has to be run through your saw which will cut some of the platform away.
The second problem might be the distance from the blade to the miter slot.
The taper jig offers two locations for the miter bar. One is 1-15/16" from the edge and the other is 3-3/16" from the edge.
As long as the cut doesn't get close to the adjusting slots on the platform it should work.
Will this do 18 degree cuts?
Josh R on Dec 30, 2018
BEST ANSWER: If you can measure it.
Has anyone used this tapering jig with a Bosch Model 4100-09 table saw?
A shopper on Aug 24, 2015
BEST ANSWER: Used it for the first time and very satisfied with the results.
Will this fit a Dewalt 7480?
DON H on Dec 19, 2018
BEST ANSWER: Yes and no. Aluminum track fits fine however jig edge sits several inches from the blade meaning the work piece is not supported as well as if it had zero clearance.
Can you do compound angles with this jig?
MARY L on Dec 17, 2015
BEST ANSWER: The jig holds the stock flat or parallel with the surface of the table saw, so by tilting the angle of the blade in the table saw, a compound cut could be achieved. Be aware that the sled does not accommodate large angles, probably about 20 degrees or less and the jig does not handle stock thicker than about 2 1/2". This will limit the compound angles that can be cut with it.
when taper cut one side how do you do the other side to match?
Dave M on Aug 28, 2016
BEST ANSWER: I keep mine in the same miter slot. If I want to cut on the other side of the board, I turn the board over. Very simple and easy.
Will this fit a 10" Craftsman Table Saw?
Thomas D on Mar 1, 2019
BEST ANSWER: Hi, this item is not specific to any make of table saw, it's the recessed guides. While I can not speak for a Craftsman table saw, I haven't seen a saw that did NOT have the recessed guides. With that said I don't think there would be a problem with your application of this jig.
Anybody use this jig with the Bosch 1031 worksite table saw? The saw is nice but small.
Jack R on May 20, 2015
BEST ANSWER: There is no reason not to be squared to your blade. Remember that after you install the sled to the bar, you have to make one pass through the saw to cut excess and that is your straight edge.
How thick of stock can you put into the jig; for example for say 2 or 3" thick tapered legs?
Craig W on Jan 21, 2016
BEST ANSWER: 2" is about as thick as you can go. I put some 2" stock through and it about maxed out the clamp width.
Can this jig be used with a Delta 10" Portable Table Saw?
K O on Aug 4, 2018
BEST ANSWER: Yes, it would work, I am using on a stationary Jet 10" saw and did have on a Dewalt 10" portable saw.
Will this work on a sliding table saw with the miter slot to the left of the blade?
Dennis O on Mar 24, 2020
BEST ANSWER: That's an interesting question. I don't have a sliding table saw, so I really don't know the answer. However, I use mine more with the jig against the fence than with the miter slot. The fence on the jig slides both ways so I think it could be used with your saw.
Will this work with Ridgid model R4513 Table Saw?
RyanHipp on Dec 2, 2019
BEST ANSWER: It should work. Most all newer tools have a standard 3/4" Miter slot and most all accessories will fit this slot.
How thick of a piece of wood will it hold?
Tom on Apr 25, 2019
BEST ANSWER: I use it to taper guitar fretboards. Works great for me. They are typically 5/16” to 1/4” thick. I am sure you could go thinner as well with no problem. I thInk you would only be limited by the rigidity of the piece against the table saw before it started to get unsafe.
The work piece is 1/2" off the table, is there a problem with tear out?
Bill S on Nov 7, 2015
BEST ANSWER: Absolutely not, because you are using the edge of the sled as your guide. Just like a zero clearance insert.
Would this taper jig work with a Delta Model # 36-725 10" table saw?
BIGJEEPMAN on Jan 19, 2020
BEST ANSWER: I have a little older Delta Unisaw. It worked very well on my saw. The jig set up easily and worked perfectly. I usually try to save money and make these things but I was rushed and needed it quickly . I am glad I bought it.
Will this work with the Sawstop Jobsite Pro?
Roger W on Oct 16, 2019
BEST ANSWER: It can be used with the t-track removed from the bottom and just using your saw fence. That's what I had to do since my table saw is a sliding table without the track. There jig works well.
WILL THIS JIG MAKE CUTS FOR FOUR SIDED TABLE LEGS? CUT ALL FOUR SIDES?
JAMES P on Jul 3, 2019
BEST ANSWER: Yes, I’ve not done it, but i can see being able to, yes!!!
I read in the reviews several people saying that the jig sets off the Sawstop brakes. I have a Sawstop. Is this true, and what can be done to avoid it, other than turning off the brake on the saw?
Jeff G on Jan 13, 2017
BEST ANSWER: I think if you set the stick on measuring tapes off the zero clearance edge it shouldn't be a problem. The metal tapes would definitely set the sawstop off. But, those tapes are stuck on and could be set 1/16-1/8" in from the cut edge and you'd be fine.
How long of a piece can you taper with this jig?
Fred V on Mar 30, 2016
BEST ANSWER: I have used my jig a few times and it works well. The board is 32 " long and the miter bar is 36". You are primarily limited by the length between the edge of your table and your blade to slide the jig for the cut. I would say you can comfortably make a 32 ' cut and may be able to go up to 36". Hope that helps. Should be adequate for most table legs since you don't normally taper the whole leg.
What is the configuration of the miter bar? "T" type or rectangular? measurements of it's cross-section?
Mark L on Mar 6, 2016
BEST ANSWER: The miter bar is must a aluminum bar measuring 3/4" x 1/2". It just slides in your miter slots when making the cut. Although, on my table saw, Delta, I am unable to use the miter bar, so I simply set the fence the distance I need to put the edge of the jig against the blade and that is my zero clearance. Works well. I've not had a problem as yet.
What is the maximum width of a board that can be tapered with this jig?
Robert C on Mar 13, 2020
BEST ANSWER: About 4”. If you remove the push handle maybe 5”.
What is the maximum width board that could be cut using this jig?
Robert C on Mar 13, 2020
BEST ANSWER: You may if you use the guide plate to hold your board. Of course it is designed for more narrow boards to be secured on the side and top.
Does it come in metric measures?
Darryl S on Jan 5, 2020
BEST ANSWER: No, It comes with 2 "stick on" strips of measuring tapes with inch units.

I suppose one could changed those for metric measure strips. One would have to purchase separately.
I purchased this once (and returned it) when I had a Grizzly cabinet saw, and the mitre slot was too far away to get the zero tolerance on the base of the jig. I now have a SawStop PCS, is the mitre slot close enough so part of the base will be trimmed off for zero tolerance? Thanks.
Tom Zarnoth on May 13, 2019
BEST ANSWER: yes! I have a SawStop, too and this works perfectly.
I just used the tapering jig for the first time, but I found when I tightened the clamps on the adjustable fence, the fence raises up and bows on one side of the slot as the head of the t-bolt underneath pulls to one side raising one side of the fence, almost coming up out of the slot. It's as though the bolt isn't resting securely in the channel. Any ideas of how to fix that?
jaykaytee on Jan 19, 2019
BEST ANSWER: I installed a ratcheting (movable) T-Bolt clamp with wide washer, which helps to stiffen the slotted fence.
Will this work for a 42" stair tread? I need to make a taper cut the full length of the tread.
Bbeck on Aug 11, 2018
BEST ANSWER: The length is doable depending on the length of the runout table. Mine is 20". The challenge is the width. Depending on the miter angle the stair tred is going to hang out beyond the taper jig base too far to be stable. My fix is to take a strip of 1/2 "MDF, plane it to 7/16 and clamp it to the saw table on the opposite side of the saw blade to give the offset stability. It'll work.
Can this be used for cutting angled back chair legs? The overall length of the leg is 36”, the bottom 18” is 90 degrees to the floor and the top 18” is tapered 12 degrees. Used the band saw freehand the first time around but thought this could be more precise.
Chris P on Jun 14, 2018
BEST ANSWER: Yes you can use this tool to make whatever angle you want to put on the leg of a chair, a side table or night stand. I am making a small table for the living room and this tapering jig is helping me to design the correct angle for the legs. I had purchased the Microjig Tapering jig, but the first time I used it, it sent a piece back at me and slapped me in the chest leaving a large black and blue mark. When I got this, and used it for the first time, I was very confident in its design and ease of use. Did NOT have the same results as with the Microjig tapering jig. This is well worth the money you spend to get great results. I purchase a lot of things from Rockler because I know they make a quality product.
Will this hold a 4x4 ?
Dominic C on Jun 4, 2017
BEST ANSWER: Not with included hardware. Get some longer bolts. I know this because I did the same thing. Then there's the issue of having a 10" table saw...
