Why Cut Angles?
Angled cuts, also known as miter cuts or bevels, are essential for joining wood at non-90-degree angles. Think about picture frames, custom molding, or even the basic structure of many furniture pieces. Without the ability to cut angles, your woodworking projects would be limited to simple squares and rectangles. Mastering this skill allows for:
- Stronger Joints: Angled joints can often be stronger and more stable than butt joints.
- Aesthetic Appeal: Many designs require angled cuts for visual interest and professional finish.
- Precise Fit: Creating angled cuts allows for perfect fits in complex assemblies.
Tools for Angled Cuts on a Table Saw
Your table saw is a powerful tool for angled cuts, and you have a few primary methods to achieve them:
1. Using the Miter Gauge
The miter gauge is the most common and accessible tool for cutting angles on a table saw. It slides into the miter slots on your table saw’s bed and holds your workpiece at a specific angle.
Setting the Table Saw Angle with a Miter Gauge
- Locate the Miter Gauge Slots: These are the two parallel channels running from the front to the back of your table saw’s surface.
- Insert the Miter Gauge: Slide the base of your miter gauge into one of the slots. Ensure it slides smoothly without excessive play.
- Adjust the Angle: Most miter gauges have a pointer or indicator that aligns with a degree scale on the base. You can unlock the gauge, rotate it to your desired angle, and then lock it firmly in place. Common angles for miter cuts are 45 degrees for picture frames.
- Table Saw Angle Measurement: Use a reliable measuring tool like a digital angle gauge or a good quality protractor to confirm the setting on your miter gauge. Many miter gauges have detents (preset stops) at common angles like 0, 15, 22.5, 30, and 45 degrees, which are very accurate.
- Blade Alignment: For precise cuts, ensure your blade is perfectly perpendicular (90 degrees) to the table surface when the miter gauge is set to 0.
How to Make a Table Saw Miter Cut Using the Miter Gauge
- Position Your Workpiece: Place the wood you want to cut against the fence of the miter gauge.
- Align with the Blade: Move the miter gauge assembly so the blade lines up with your desired cut mark on the workpiece. Ensure the workpiece is held firmly against the fence.
- Make the Cut: Turn on the table saw. With the blade at full speed, slowly push the miter gauge and workpiece through the blade. Never force the cut.
- Support Your Workpiece: For longer pieces, ensure they are well-supported to prevent tipping or binding.
2. Using the Table Saw Angle Fence (or Miter Sled)
A table saw angle fence, often referred to as a miter sled or angle jig, is a specialized jig that attaches to your table saw or is built to slide in the miter slots. These jigs are designed to hold your workpiece at a precise angle and offer more stability than a standard miter gauge, especially for smaller pieces or repetitive cuts.
Building or Using a Table Saw Angle Jig
Many woodworkers build their own table saw crosscut sleds with an adjustable angle feature. These are excellent for making repeatable, accurate angled cuts.
- Adjustable Miter Sleds: These often feature a pivot point that allows you to set and lock the angle of the sled’s fence.
- Fixed Angle Jigs: Simpler jigs are built for a specific angle, like a 45-degree miter sled, which guarantees perfect 45-degree cuts every time.
Steps for Using an Angle Jig:
- Set the Angle: If your jig is adjustable, set it to the desired angle using its built-in scale or an external angle gauge. Lock it securely.
- Position Workpiece: Place your workpiece against the fence of the jig.
- Align with Blade: Ensure the jig’s fence is set to the correct angle relative to the blade.
- Make the Cut: Push the jig and workpiece through the blade smoothly.
3. Cutting Bevels on Table Saw with the Blade Tilt
This method involves tilting the table saw blade itself to create an angled cut across the thickness of the wood, not just the width. This is crucial for tasks like creating the angled edges of a box or a chamfer.
Table Saw Bevel Cutting Techniques
- Tilting the Blade: Most table saws have a mechanism to tilt the blade. Look for a handwheel, usually at the front of the saw, marked with degree increments.
- Setting Table Saw Angle: Turn the handwheel to tilt the blade to your desired bevel angle. Use the degree indicator on the saw.
- Using a Digital Angle Gauge: For maximum accuracy, use a digital angle gauge placed on the tilted blade to verify the precise angle.
- Blade Height: Ensure the blade is raised to the correct height for your cut. For bevels, you typically want the blade to extend just slightly above the workpiece.
Making a Table Saw Bevel Cut
- Set the Blade Tilt: Tilt the blade to your desired angle using the tilt mechanism.
- Secure Workpiece: Place your workpiece on the table saw surface, flat against the rip fence.
- Align for Cut: Adjust the rip fence so that the blade will cut at the correct distance from the edge of your workpiece.
- Make the Cut: Turn on the saw. Slowly push the workpiece through the blade, keeping it firmly against the rip fence. Be aware that the offcut piece will be narrower due to the blade’s tilt.
Using a Miter Gauge Table Saw for Bevels
You can combine the use of a miter gauge with a tilted blade for cuts that are both angled and have a bevel. However, this can be more complex and requires careful attention to ensure safety and accuracy.
- The Challenge: When the blade is tilted, the angle the miter gauge presents to the blade changes relative to the workpiece.
- Solution: You’ll need to adjust your miter gauge angle based on the blade’s bevel angle to achieve the desired final angle on your workpiece. This often involves some trial and error or precise calculation. For example, if you want a 45-degree angle on the edge of a board and the blade is tilted 10 degrees, you might need to set your miter gauge to a different angle (e.g., 35 degrees or 55 degrees depending on the setup) to compensate.
Table Saw Angle Fence for Bevels: Some specialized angle jigs are designed to accommodate a tilted blade, providing a stable platform for making bevel cuts with increased accuracy.
Achieving Precision: Tips for Accurate Angled Cuts
Accuracy is key when cutting angles. Here are some tips to ensure your cuts are precise:
1. Calibration and Measurement
- Zeroing Your Miter Gauge: Always ensure your miter gauge is set precisely to 0 degrees when checking for square cuts.
- Accurate Table Saw Angle Measurement: Use a reliable angle finder. While the built-in scales are useful, a digital angle gauge offers superior precision.
- Marking Your Cut Line: For critical cuts, use a sharp pencil and a reliable square to mark your cut line clearly.
2. Blade Selection
- Blade Kerf: Be aware of the blade’s kerf (the width of the cut). This is especially important when making two complementary angled cuts for a joint.
- Blade Tooth Count: A blade with a higher tooth count (e.g., 60 or 80 teeth) will generally produce a cleaner cut on hardwoods and crosscuts, which is beneficial for angled cuts.
3. Workpiece Support
- Long Workpieces: For long boards, always ensure they are well-supported before, during, and after the cut. Use outfeed tables or roller stands.
- Small Workpieces: Small pieces are best cut with a table saw crosscut sled or a specialized jig to keep your fingers safely away from the blade.
4. Safety First!
- Blade Guard and Riving Knife: Always keep your blade guard and riving knife (or splitter) in place whenever possible.
- Push Sticks and Push Blocks: Use push sticks and push blocks to guide the workpiece through the cut, especially for smaller pieces or when cutting close to the blade.
- Never Reach Over the Blade: Maintain a safe distance from the spinning blade.
- Stand to the Side: Position yourself so you are not directly behind the workpiece as it passes through the blade.
- Check for Binding: Ensure the wood is not binding against the blade. This can happen with warped wood or improper setup.
Common Angled Cuts and Their Applications
Let’s look at some typical angled cuts and why you’d make them.
The Miter Cut
A miter cut is an angled cut made across the width of a board.
- Typical Angles: 45 degrees is the most common for joining corners.
- Applications: Picture frames, boxes, window trim, crown molding.
- Table Saw Method: Use a miter gauge or a miter sled.
The Bevel Cut
A bevel cut is an angled cut made across the thickness of a board.
- Typical Angles: Can be any angle, but 15, 22.5, 30, or 45 degrees are common.
- Applications: Edges of boxes, creating chamfers, joining boards at an angle on their edges, furniture legs.
- Table Saw Method: Tilt the table saw blade.
Compound Angle Cuts
A compound angle cut is a cut that has both a miter angle (angle across the width) and a bevel angle (angle across the thickness).
- Applications: Most complex trim work, architectural details, joinery in specialized furniture.
- Table Saw Method: Requires tilting both the blade and setting a specific angle on your miter gauge or jig. This is an advanced technique that requires practice.
Advanced Techniques and Jigs
For those looking to take their angled cuts to the next level, consider these advanced options:
Table Saw Crosscut Sled Angle Modification
While a standard crosscut sled is designed for 90-degree cuts, you can modify them or build new ones that allow for adjustable angles. This typically involves creating a pivot point for the fence on the sled that allows it to be set to any desired angle.
Custom Angle Jigs
For highly specific or repetitive angled cuts, building a custom jig tailored to your needs is often the best solution. This might involve:
- Repeatable Angle Jigs: Jigs with precisely set angles that ensure consistency.
- Jigs for Specific Operations: Jigs designed for cutting specific types of joints or moldings.
Troubleshooting Common Issues
Even with the best preparation, you might encounter problems. Here’s how to address them:
| Issue | Cause | Solution |
|---|---|---|
| Inaccurate Angle | Miter gauge not set precisely | Recalibrate miter gauge; use a digital angle gauge for verification. |
| Miter gauge slot too loose | Clean slots; use a zero-clearance insert or shims if needed. | |
| Blade tilt scale inaccurate | Use a digital angle gauge to verify blade tilt. | |
| Rough Cut Surface | Dull blade or wrong blade for the material | Use a sharp blade with an appropriate tooth count for crosscuts/bevels. |
| Blade not spinning at full speed | Allow blade to reach full RPM before cutting; check motor belt. | |
| Feed rate too slow or too fast | Maintain a consistent, moderate feed rate. | |
| Burning on Cut Edge | Feed rate too slow | Increase feed rate slightly. |
