How to Cut Tapers on a Table Saw: The 7-Step Process

To cut tapers on a table saw, you need a jig to hold the workpiece at a fixed angle, typically 5 degrees or less, and guide it safely past the blade. The most reliable method is building a simple tapering sled from plywood, using a guide rail, a cleat, and T-bolts for adjustment. This approach is safer than freehanding and more accurate than most commercial jigs for one-off projects.

The sled’s design is straightforward, but its dimensions are not universal. The base dimensions for a SawStop sled are 9″ wide and 32″ long, but you must adjust dimensions as needed to fit your saw. That misalignment is the difference between a crisp taper and a piece that binds, kicks back, or tears out along the grain. Understanding how to cut tapers on a table saw is key to avoiding these issues.

What follows is the build, the layout math, and the cuts. We’ll walk through adapting the jig to your specific saw, the one safety rule you must never break with a taper, and how to handle the skinny offcut without turning it into a dangerous projectile.

Key Takeaways

• Build your tapering sled to fit your saw’s specific measurements, especially the miter-slot-to-blade distance; a generic size guarantees misalignment and kickback.
• Never use the rip fence and miter gauge together; for taper cuts, the jig replaces the fence, guiding the workpiece at an angle while the miter slot controls the path.
• Use a push stick for any piece under 6 inches wide during the cut, and never rip a workpiece shorter than 10 inches, the taper jig doesn’t change these fundamental safety rules.
• A subtle taper is usually 5 degrees or less; the longer the leg, the more subtle the angle needs to be to look proportional.
• Support the tapered face with the first cut’s offcut when making a second taper on the adjacent side; this keeps the workpiece level for a perpendicular entry into the blade.

The Anatomy of a Tapering Sled

A tapering sled is just a moving platform with an adjustable fence for how to cut tapers on a table saw. Its job is to hold your workpiece at a precise, repeatable angle while the miter bar in your saw’s slot guarantees a straight pass. You can buy one, but for less than a sheet of plywood and an hour in the shop, you get a jig tailored to your machine.

The SawStop design is a good template, using a base 9 inches wide by 32 inches long, a guide 3 inches wide by 31-1/2 inches long from 3/4″ plywood, and a 5-inch span from the miter slot to the blade. Their sled uses a base 9 inches wide by 32 inches long, a guide 3 inches wide by 31-1/2 inches long from 3/4″ plywood, and a simple cleat. The critical dimension is the 5-inch span from the miter slot to the blade on their Professional Cabinet Saw. Your saw is different.

The base must be wide enough so the guide, once attached, sits entirely to the left of the blade when the sled is fully forward. If the guide crosses the blade’s path, you’ll cut into your jig on the first use.

Here’s the breakdown of the core parts and why they matter:

Component	Typical Spec (From 3/4″ Plywood)	Its Job
Base	9″ wide x 32″ long	Provides a stable platform that rides in the miter slot via an attached bar.
Guide	3″ wide x 31-1/2″ long	Acts as the adjustable fence; workpieces clamp against it.
Cleat	1/2″ x 3-1/2″	Screws to the guide’s end as a stop block for consistent workpiece positioning.
T-Bolt Slots	Two, 5/8″ wide x 1/8″ deep, then through-cut with 1/4″ bit	Allow the guide to slide for angle adjustment and lock down securely.
Miter Bar	Shop-made or purchased	Connects the sled to your table saw’s miter slot, ensuring straight-line travel.

You’ll need a router with a 5/8″ straight bit and a 1/4″ or 5/16″ bit to cut the T-bolt slots. A drill, screws, and some T-bolts or knobs from the hardware store round out the supplies. The cleat gets screwed on, no glue, so you can replace it when it gets chewed up.

Step-by-Step: Building Your Custom Sled

This isn’t a one-size-fits-all plan. Before you cut any wood, you need two numbers: the distance from your left miter slot to the blade, and the length of your miter slot. The first number defines your sled’s width; the second dictates how long the base can be before it overhangs the table unsafely.

First, measure your saw. Lower the blade fully. Use a combination square to measure from the left edge of your left miter slot to the right side of the blade teeth. That’s your critical offset. For the SawStop, it’s 5 inches. For a portable jobsite saw, it might be 4 inches. Write it down.

1. Cut the base. Rip a piece of 3/4″ plywood to a width that fits your saw, using the SawStop base width of 9″ as a reference but adjusting as needed. Crosscut it to a length that fits your table, using the SawStop base length of 32″ as a reference but adjusting as needed. A longer sled supports longer workpieces.
2. Attach the miter bar. Place dimes in the miter slot to lift a commercial or shop-made miter bar slightly. Use double-faced tape to stick the bar to the bottom of your base, aligned with the slot. Then, screw the bar securely to the base from the top. Remove the dimes.
3. Cut the guide. Rip a piece of 3/4″ plywood to 3 inches wide. Crosscut it to a length that fits your base, using the SawStop guide length of 31-1/2″ as a reference but adjusting as needed.
4. Rout the T-bolt slots. This is a two-stage process. Clamp your base to a bench. With a 5/8″ straight bit in a router and an edge guide set, cut a 1/8″-deep slot across the base’s width, positioned as needed for your T-bolts. Do not cut all the way to the edges. Then, switch to a 1/4″ straight or spiral bit. Plunge through the center of each wide slot, making multiple passes until you cut completely through the base. This creates the “T” for the bolt head.
5. Attach the cleat. Cut a small block from 3/4″ plywood to 1/2″ by 3-1/2″, as used in the SawStop design. Screw it to one end of the guide. This gives you a positive stop to register your workpiece against.

Test the sled on your saw without the guide attached. It should slide smoothly in the miter slot with no side-to-side play. If it binds, your miter bar needs adjustment. This foundation is more important than a perfect-looking guide.

The 7-Step Layout and Cut Process

With the sled built, the real work begins. Cutting the taper is straightforward; laying it out correctly is where most projects go off the rails. You’re not just drawing a line. You’re defining the amount of material to remove from a specific face, in a specific orientation.

Imagine you are tapering a 2×2 table leg. You only taper the two inside faces. The first cut establishes the angle; the second cut must reference from the newly created tapered surface.

Common mistake: Marking the taper on the wrong face or forgetting which end is the “top.” Always mark the waste side clearly with an “X”. The blade kerf falls on this side of your line.

Here is the sequence, step by step:

1. Mill your workpiece square. All four faces must be straight, parallel, and at 90 degrees. Tapering magnifies any twist or cup.
2. Determine taper dimensions. Decide how much you’re removing. Determine taper dimensions based on your design needs. Mark these points on the corner of the workpiece.
3. Connect the marks. Use a straightedge to draw a line from the top mark to the bottom mark on the face you’re tapering. This line is your cut line.
4. Set up the sled. Place your workpiece against the guide and cleat, with the waste side overhanging the base. Slide the guide until your pencil line is perfectly parallel to the sled’s travel. Lock the guide down with the T-bolts. Clamp the workpiece securely to the guide. Use two clamps if possible.
5. Prepare the saw. Install a sharp, fine-tooth blade suitable for clean crosscuts or rips. Ensure the riving knife is aligned and the blade guard is in place for this through-cut.
6. Make the cut. With the saw on, use a steady feed rate to push the sled and workpiece through. Keep your hands clear of the blade path and use a push block on the sled itself if needed. Let the offcut fall away to the side.
7. Cut the second taper. This is the trick. Take the wedge-shaped offcut from your first cut and place it on the sled, tapered side up. Now, place your leg on top of it, with the newly tapered face down. This cradles the workpiece, keeping it level so the second cut enters the wood squarely. Clamp and cut.

The sound of a proper taper cut is a consistent, medium-pitched hum. If you hear the motor bog down, you’re feeding too fast or the blade is dull. If you hear a high-pitched screech, the workpiece is pinching the blade, stop immediately, as kickback is imminent.

Safety Rules That Aren’t Optional

A taper jig changes the geometry of the cut, but it doesn’t suspend the laws of physics or the manufacturer’s safety rules. In fact, it introduces a new hazard: a long, thin offcut that can twist and bind.

The CRAFTSMAN manual is unambiguous on several points that apply directly to taper cutting. These are not suggestions.

• Never use the rip fence and miter gauge together. When using your tapering sled, the sled itself is the guiding device. The rip fence must be removed or positioned completely out of the way. Having both a fence and a guided jig in play is a classic kickback setup.
• Use a push stick for narrow work. The manual specifies a push stick for any piece 6 inches wide or less. When your workpiece is clamped to the jig, the “width” in question is often the offcut piece, which can be very narrow. Have a push stick ready to control the sled and keep your hands safe.
• Never rip a workpiece shorter than 10 inches. This rule still stands. If you’re tapering a short block, find another method. A piece that short is difficult to clamp securely to the jig and places your hands too close to the blade.
• ALWAYS wear safety goggles (ANSI Z87.1). Sawdust and small offcuts will be flying. Everyday glasses are not enough.
• Feed against the blade rotation. This is automatic with a sled, but remember: you always push the workpiece into the blade’s cutting arc, never with it.

Where this goes sideways: Trying to cut a second taper without using the first offcut as a support. The workpiece rocks, the blade catches at an angle, and the piece either tears out or gets thrown backward.

Your guarding system is your friend. For a through-cut like a taper, the blade guard, riving knife, and anti-kickback pawls should be installed. They make the cut safer without affecting the sled’s operation.

Commercial Jig vs. Shop-Made: The Real Choice

You can buy a tapering jig. Models from JessEm, Rockler, or Kreg offer convenience and often come with built-in scales for setting angles. So why build one?

A shop-made sled wins on three fronts: cost, customization, and capacity. For under $20 in materials, you have a jig. You can make it as long as your table can handle, allowing you to taper table legs or long table aprons with full support. A commercial jig might max out at 24 inches.

The built-in scales on a store-bought jig are useful, but they’re only as accurate as your setup. With a shop-made sled, you set the angle directly off your marked workpiece, guaranteeing the taper you drew is the taper you get. It’s a direct, foolproof transfer.

For a woodworker who cuts tapers once a year for a specific project, the shop-made sled is the clear choice. It’s a simple, afternoon project that pays off in accuracy. If you’re a production shop churning out hundreds of tapered legs, the repeatability and speed of a high-end commercial jig justify its cost.

Troubleshooting Taper Problems

Even with a well-built jig, things can go wrong. The fix is usually in the setup, not the cut.

Problem: Tear-out along the taper.

The blade is either dull or has the wrong tooth geometry. A sharp blade designed for clean cuts slices the wood fibers cleanly. A dull blade or a blade with a low raker tooth tears them. Switch to a sharp blade suitable for fine woodworking. Also, ensure your workpiece is firmly clamped, any vibration promotes tear-out.

Problem: The taper isn’t straight; it curves.

This is a sled alignment issue. The guide is not parallel to the direction of travel. Loosen the T-bolts, re-align the guide using a known-straight edge registered against the blade (unplug the saw first!), and re-tighten. The miter bar itself might also have play in the slot.

Problem: The offcut pinches the blade near the end of the cut.

This is internal stress in the wood releasing, or more commonly, the thin offcut flexing. Support the offcut with your push stick or a dedicated offcut support roller. Don’t let it droop.

Problem: Kickback during the cut.

This is the most serious. The causes are typically a misaligned guide (causing a pinching kerf), a missing or misaligned riving knife, or attempting to cut a workpiece that is warped or twisted. Stop. Unplug the saw. Check all alignments and the straightness of your stock.

Handling Thin Offcuts and Dangerous Scraps

The waste piece from a taper cut is a long, thin wedge. It’s flexible, unstable, and can whip around at the end of the cut. Your instinct might be to catch it or guide it with your hand. Don’t.

The safest practice is to let it fall onto the table and then clear it after the saw is off. For a cleaner workflow, set up an offcut support table or roller to the right of your blade. This catches the thin piece and supports it through the entire cut, preventing it from twisting into the blade.

If the offcut is particularly skinny (less than 1/4 inch at its thickest), consider making a relief cut first. Use your table saw crosscutting skills to trim the workpiece to near-final width before tapering, leaving less fragile waste. This is a core technique for any basic table saw operation guide.

Cutting Long Tapers

A tapering sled is the right tool for a long, straight taper. The sled’s base needs to be long enough to fully support your workpiece, so you may need to build one longer than typical dimensions. The adjustable fence on the sled holds the long board at your chosen angle, while the miter bar in the table’s slot controls the cut. The CRAFTSMAN manual advises using all components of the guarding system (blade guard assembly, riving knife and anti-kickback assembly) for every operation for which they can be used, including through cuts. Never use the rip fence together with the sled’s miter bar. The CRAFTSMAN manual states that feed force when ripping should always be applied between the saw blade and the fence.

Frequently Asked Questions

What is the best way to cut a taper on a table saw?

The best way is with a dedicated tapering sled or jig. It holds the workpiece at a fixed angle and rides in the miter slot, ensuring a straight, safe, and repeatable cut. Freehanding against the fence is dangerous and inaccurate.

Can I use my miter gauge to cut tapers?

Not effectively. A miter gauge sets an angle relative to the blade, but it doesn’t provide a long reference surface to hold a workpiece at a consistent angle along its length. For a true taper, you need a jig with a long guide fence.

How do I set the angle on a tapering jig?

For a shop-made sled, you don’t set a numeric angle. You place your marked workpiece against the guide, slide the guide until your pencil line is parallel to the blade, and lock it down. This directly transfers your layout to the jig.

Is a bandsaw better for cutting tapers?

Bandsaw can be safer for roughing out a taper, especially on very thick stock, as it’s less prone to kickback. However, it leaves a rougher surface that requires cleanup. The table saw with a jig produces a glue-ready surface straight off the blade, which is why it’s preferred for furniture work.

How do I cut matching tapers on four table legs?

Cut all four legs in batches by step. Lay out and cut the first taper on all four legs. Then, without moving the sled setting, use the offcut from your first leg to support each subsequent leg for its second taper. This guarantees all four are identical.

Before You Go

Tapering on the table saw demystifies a lot of furniture design. That elegant, lightweight look comes from a simple jig and a disciplined process. The sled is the easy part. The discipline is in the layout, the clamping, and respecting the kickback zone that a thin offcut creates.

If your first taper has tear-out, look at your blade first. A dedicated fine woodworking blade makes a visible difference. If the taper wanders, the problem is almost certainly your sled’s alignment, not your technique. Go back and square the guide to the blade’s path, every time.

Finally, this whole process assumes your saw is tuned. If your table saw fence isn’t parallel to the blade, or your table isn’t flat, you’re fighting an uphill battle. Get those fundamentals right first. Then a perfect taper is just a matter of drawing a straight line and having the patience to set up the jig correctly. The cut itself should be the quietest, most uneventful part of the whole operation.
