Jointing on the Table Saw

Jointing on a table sawThere are plenty of times when you need your boards to have a smooth, straight edge. No jointer? No sweat. With the help of a simple shop-made jig you can be jointing on the table saw.

Even if you own a jointer, jointing on the tables saw is a handy technique to know about. If you ever need to clean up edges on abrasive material like plywood, particle board, plexiglass…the carbide teeth of a saw blade will stand up to it much better than tool steel jointer knives.

You’ll need to build a jig, and then create an offset in the jig to get the same affect as the offset tables on a jointer.

Getting started


I built my jig from ¾” melamine, but any material will work. Since you’ll be using it for jointing you’ve got to be very careful to rip nice, straight edges onto the parts. The vertical piece is 3” wide, tall enough to easily clamp to my rip fence. The horizontal piece is 4” wide. The length of the jig determines the length of the pieces you can joint. I made mine 6” longer than my rip fence.

Jointing-on-the-table-saw-positioning-the-jigClamp the jig to your rip fence so that it’s approximately centered on the length of the fence.

Jointing-on-a-table-saw-blade-selectionPick the right blade. A 40-tooth alternate top bevel blade works great. A thin kerf blade is better than a standard blade since the thickness of the blade determines how much material you’re taking off with each pass.

Set the blade to the right height, slightly higher than the thickness of your material.

Cutting the offset

Jointing-on-a-table-saw-set-up-to-cut-jigRemove the jig from the rip fence and move the fence to the left side of the blade. You need to VERY carefully position the fence for the cut in the jig that creates the offset. Be sure your saw is unplugged.

Jointing-on-a-table-saw-position-for-cutAlign the right side of the saw blade with the right edge of the jig. It’s easier to feel this with your finger than it is to see it. Make small adjustments to the rip fence position until it’s correctly set.

Jointing-on-a-table-saw-cut-the-offsetWith the fence correctly positioned, add a feather board and cut the jig. When making this cut, don’t allow the jig to pull off the rip fence. The feather board helps a lot.

Jointing-on-a-table-saw-stopped-cutStop cutting when you get to the pencil mark you made earlier. Turn off the table saw.

Jointing-on-a-table-saw-check-the-offsetWith the saw unplugged check the offset. With the jig tight to the rip fence the right edge of the saw blade must be perfectly even with the right edge of the jig. If the blade projects past the jig you don’t have enough offset. Move the rip fence to the right, slightly, and make another cut. If the jig projects past the blade you’ve create too large an offset. You’ll need to rip the offset off and go through the positioning steps again to cut a new offset.


Jointing-on-a-table-saw-set-the-fenceMove the rip fence to the right side of the saw blade. With your saw unplugged, clamp the jig to your rip fence so that the back of the blade aligns with the offset.

Jointing-on-a-table-saw-confirm-jig-positionThe left side of the saw blade should align with the left edge of the jig, and the blade should turn freely. Adjust the position of the rip fence until this is correctly set.

Jointing-on-a-table-saw-test-cutMake a test cut.

Jointing-on-a-table-saw-test-cut-resultsCheck the results. If you’re getting a slight sliver, the jig is too far from the blade. Make small changes in the fence position until the sliver goes away, and the blade can spin without touching the jig.

Jointing-on-the-table-saw-making-the-cutOnce you’ve tweaked the fence position, you’re ready to joint!

A dose of reality

If you’re careful with the set up, this technique works well. Should you sell your jointer? I think not. Without question it’s easier to turn on a jointer and make a cut than it is to set up the jig on your table saw. But if you don’t own a jointer, or need to joint abrasive materials, the results from the table saw are good, plenty smooth enough for edge to edge glue ups.

This works great on ¾” thick stock. Thicker than that and the results deteriorate. I suspect the thin kerf blade flexes a little on thick stock, since it’s only cutting on one side.

    I liked this idea, so I made one. The only problem was that it only had one depth setting, the kerf of the saw blade. I modified it to put a very thin strip of wood on the “infeed” side of the jig and was able to get a finer cut. So far it works great.

    • tombaugh

      I don’t understand your comment re: depth of cut and modification.
      If you have a 1-1/2″ board to joint why couldn’t you just raise the blade? I’m missing something here..

      • David

        I believe the “depth of cut” that Don is referring to is not the vertical height of the saw blade but the left to right thicknes of the saw blade. If a standard 1/8″ blade was used, then every pass using this method would remove 1/8″ of material from the jointed board.
        If a thin kerf blade is used, then apx. 3/32″ would be removed. So Don is suggesting if you want less than 3/32″ depth of cut, then add a very thin strip of say 1/32″ onto the infeed edge of the jig but not in the area where the saw blad would line up. This way, you would then remove 2/32″ with each pass.
        Hope that makes sense.

    Awesome! I was directed here after submitting a question about jointing without a jointer for the live broadcast on March 19, 2015. George showed this jig and directed me to this webpage. I’ll be making one of these very soon. Thanks!

    Instead of all farting around with shims&fine adjustments . Why not just buy jointer ! this sounds way to difficult and to much like work this is suppose to be relaxing and fun . go buy jointer $2200.00

    Great idea I have struggled with no jointer. I use the planer the best I can, but it does not work as well as this would. Suggestion: On the first pass with cutting the jig, do not take a full kerf cut. Take a cut that is 1/16. Lower the blade and attach the jig to the fence and adjust it so the end of the 1/16 cut is over the saw blade and the outside of the saw blade is even with the uncut portion of the jig. Turn on the saw and raise the blade. You are now set up to remove in 1/16 from your stock. Take multiple passes if needed. I think the thinner cut would also result in less blade deflection.

    Nice instructions I was wondering how to cut the I know…thanks!

    It’s not clear how you cut the inset. Did you move the melamine sideways into the blade. It will be important to communicate this. If you cut the jig all the way through the blade, you are back to sq 1 with no offset.

      Photos 6-10 in the article demonstrate how this is done. You move the fence to the other side of the blade, which allows you to flip the jig around and send the end that is normally rear facing through the saw first.

  7. Michael fahey

    Ok I get it the offset is one only one side of the blade so only the width of the kerf is exposed to the Infed stock.

    Wouldn’t this fail on a board that does not have a straight edge? Most solutions I have seen use a straight board as a sled and have hold-downs so the piece you are cleaning up sits on the sled and hangs over the edge on the blade side. It works for any board no matter how messed up the edge is. Once you have one edge straight, it is easy to clean up the other side and get parallel edges.

    Ticket 20414 Why is using this jig better than just running each board of your panel through between the fence and the blade to straighten it on both sides taking a 1/16″ off of both sides?

    • Customer Service

      Dear Tom,

      Thank you for your patience. In regards to your question-

      this jig holds the board in a fixed position so that the cut edge can be perfectly straight. Running the board against the fence will cause the cut edge to shift if the board is longer than the fence, which causes both cut quality and safety concerns.

        I’m still not getting it. If I understand the jig construction and it’s use, the board you are trying to join can rock away from the jig just as easily as it can from the fence. Maybe a little less so since the jig has a longer in-feed and out-feed to it than the fence. The method I described is no less dangerous (Maybe less so) than just ripping a board. I’m still confused. Sorry.

        • Customer Service

          Hi Tom. My apologies, I was referencing the wrong jig with my previous response. The jig that you are asking about works differently. You are essentially turning your table saw into a jointer with this jig. It supports the cut edge as it comes off the blade, holding the board perfectly straight on the outfeed side. You need to start with a board that is pretty straight, and then you can perfect the straightness of the edge using this jig. Don’t expect to straight out a board with a bad bow to it with this jig. Just like with a jointer, you’ll want to use some other means of getting the board “pretty straight” before you run it through here. I commonly use a straight edge to draw a line, then cut to that line using my bandsaw, then run it through the jointer. In this case you would substitute your table saw and this jig for the jointer.
          It would say that you will see the most noticeable advantage using this jig if you have a short stock fence on your table saw, and you extend that with this jig. For a high end table saw with a longer fence, you might not notice as much advantage.

            NB Ticket 22278 There are a lot of different schemes on the web for using a table saw as a jointer, but all the others I’ve seen have a jig that moves parallel to the rip fence with the work piece clamped to the jig. This design is unique and mimics a real jointer. It remains stationary and has infeed and outfeed sides that are on different planes. Can you explain why this method would provide better results?

          • Customer Service

            Dear Jan,

            Thank you for your patience. In response to your question-

            Ultimately either approach can produce the same result, which is a flat and straight edge that can be used for glue-ups. It’s really up to you to choose the approach that is more appealing to you.

    I’m not understanding what does the off set do? Why couldn’t you just have a straight edge to the jig?

    • Customer Service


      The offset is so that you can use your table saw just like a jointer which has off-set infeed and outfeed tables.
