How To Make A Crosscut Jig For Table Saw – Table saw carriages (or cross-slides) make cutting cross-grained wood safer and much easier. There are many technical ways to approach making a table saw sled, but sometimes you need a simple and elegant solution to a problem. This is probably the simplest cross slide you can do and still get accurate cuts.
A cross slide (in case you don’t know) is used to cut against the grain of wood on a table saw or to cut very small pieces without fear of cutting your fingers. Cross cutting (or mirror cuts) is a topic covered in this free table saw lesson that will take you from zero to hero in being a professional table saw.

These cross slides can be made from scraps and only require three cuts to be precise, the rest can be glued together with reckless abandon and the railing can be cut square. At the end of the Instructable, we will use the cut 5 method to check the accuracy of the sled after it is made.
Bought Myself A Table Saw For My Birthday Last Tuesday. This Weekend I Built Myself A Rolling Table And A Cross Cut Sled.
This circular sled uses scrap wood, relying on a few precise cuts and a very straight piece of hardwood. Here’s what you’ll need to make your own:
Gauges are essential for accurately measuring the ground footprint of your circular saw. You will also need a solid triangle to line up the sled with the blade, which will determine whether or not the cuts are square.
Make sure the table saw is calibrated before making any cuts or every cut you make will be wrong. Table saw calibration is largely covered by the table saw class.

Most table saws have a standard measurement of 0.75″ wide x 0.375″ deep. It is best to check and determine the miter size before making any cuts.
Digital calipers have 4 measuring points: external dimensions (large jaws that protrude from the object to be measured), internal dimensions (smaller jaws that enter inside the object to be measured – located above the larger jaws), depth gauge (probe that exits from the end ) and an external depth indicator (the front of the hammer yoke and the inner jaw of the moving part – example).
Use an internal measurement to check the width of the miter rail, then use a depth gauge to determine how deep the track is.

Place the table saw fence at the width of the rail and make a cut on the straight hardwood waste. Then set the fence to the miter depth and go through the cut wood again.
Here we use hardwood like oak, as it is a very dense and strong wood that is not prone to warping. Using this as our track will allow the sled to slide smoothly and not get stuck on the sloped track.
Before checking the cut, it is advisable to clean the surface of the table saw and the groove of sawdust or dirt. If you neglect this step, you will not get an accurate assessment of whether your cut fits the track exactly.

Place the hardwood in the mirror fence to test the fit. Try pushing the hardwood along the rail and see if it sticks anywhere, then try twisting the hardwood sideways on the rail to see how much it slides or plays.
You’re looking for a snug fit with no slack and a smooth glide. If you get stuck, check the rail to make sure it’s free of debris, then try sanding the hardwood sections to get a proper fit. If all else fails, you can always measure and rip another piece of hardwood until you get the right fit.
Using the rail cut, we can make the base of the sled. The best thing about this type of sled is that the base of the sled doesn’t have to be perfectly square at all.

I used a ¼” piece of plywood with very rough edges, perfect for this application!
This plywood base will sit on top of the rail and be the bottom of the sled. Since it’s just a platform and no measurements will be taken from it, it doesn’t need to be anything more than a flat surface that we can cut.
Apply a small bead of hardwood glue along the entire length, being careful not to use too much or accidentally spill the glue on the circular saw. You only need a small amount of glue as we will be adding screws later to secure the hardwood to the plywood.

After applying the glue, place the plywood on top of the hardwood rail, align the plywood so that it is roughly perpendicular to the rail, and the center of the plywood is flush with the saw blade.
After the glue has dried, slide the glued assembly off the inclined rail and turn the plywood over.
Drill pilot holes the length of the hardwood and countersink each hole you make. Hand screw fasteners into each hole to mechanically secure the hardwood to the plywood. The combination of glue and screws will ensure that the two parts are securely connected.

It is important to cut the holes so that the ends of the screws are inserted into the surface of the hardwood rail so as not to prevent any movement when the sled is in the rail.
The front fence of the sled (the part farthest from you when you control the sled) doesn’t need to be precise as its only job is to support the frame of the sled when we cut the notch in the plywood.
I used scrap wood glued along the front edge of the plywood, just making sure the scrap wood was square enough so that the surface would stick to the plywood properly.

Before gluing on the rear slide guide, which must be perpendicular to the blade, a reference cut must be made. The back fence must be perpendicular to the saw blade and perfectly square to make accurate cuts.
With the saw stopped, remove the insert and remove the riving knife, then place the insert back on the blade and lower the blade to the table. We will run the blade through the plywood base to create a reference cut that we will align the board to.
Place the sled in the miter rail and place the plywood directly over the lowered blade. Lower the saw and slowly raise the blade until it is about 1″ above the surface of the plywood base, holding the plywood with your other hand (away from the blade) as needed to keep the plywood from moving as you cut.

The notch is the material that is removed during cutting and is equal to the thickness of the blade, it is described in more detail in the table saw class.
The back fence of the sled is the only other piece of wood that needs to be accurate for this sled. This back fence will be where you line up the cut wood in relation to the saw blade, so it needs to be square and perpendicular to the blade.
Use a three-point square to make sure your wood selection is completely square and straight. Like the front fence, the wood for the back fence should be as long as your sled is wide.
Make A Simple, Sturdy Crosscut Sled
With the saw stopped and the blade extended through the plywood, place the trident on the face of the blade. Note that the teeth of the saw are slightly wider than the face of the saw, so make sure the triangular teeth go past the teeth and are flush with the face of the saw blade.
With the triangle flush with the blade, line up the square guard with the perpendicular arm of the triangle to set it at a 90° angle to the blade.
Apply a small bead of glue to the back fence and place it on the plywood. This is the most critical part of the entire slide, as misalignment will cause any cuts made on the slide to be skewed. Take the time to make sure the back fence is completely perpendicular to the saw blade.
Crosscut Sled Stop & Hold Down
Once you are satisfied that the guard is aligned perpendicular to the saw, allow the glue to dry overnight before continuing.
Similar to the hardwood rail, once the glue dries you can turn the sled over and drill and tap the holes to attach the rear stop with screws.
With the back fence attached, raise the blade about ½” above the surface of the plywood and slide the sled all the way over the blade. Your sled is functionally complete!

To check the accuracy of the sled, we will use the 5-cut method, cutting a piece of scrap 5 times, rotating after each cut to see the deviation from perpendicular.
By making several successive cuts on the same piece of wood, the resulting fifth cut will magnify the error and show us our deviation.
Start with a rectangular piece of wood and mark each side 1-4 counter-clockwise. This piece of scrap doesn’t have to be square to begin with, cutting method 5 will handle any scrap piece of any shape.
