How To Extend Wooden Table Legs？

Extending the legs of a wooden table can be a practical solution to various needs. Whether you're seeking to increase comfort, match new seating, or simply give an old table a fresh look, adding height to your table legs is a manageable DIY project. This comprehensive guide provides detailed instructions, helpful tips, and considerations for successfully extending your wooden table legs.

Why Extend Table Legs?

There are several reasons why you might want to extend the legs of a wooden table:

• Ergonomics: Raising the table height can improve posture and comfort, especially if you're using it for work or dining2.

• Aesthetics: Taller legs can change the overall look of the table, making it appear more modern or elegant6.

• Matching Furniture: If you've acquired new chairs or other furniture, you might need to adjust the table height to create a cohesive look2.

• Adaptive Reuse: Extending the legs can repurpose a coffee table into a dining table or a side table into a desk9.

Planning Your Table Leg Extension

Before you begin, careful planning is essential. Here’s what to consider:

• Measure the Existing Height: Determine the current height of your table and how much additional height you need6.

• Choose the Right Extension Method: Select the method that best suits your skills, tools, and the table's design6.

• Select Materials: Choose wood that matches the existing table legs in terms of species, color, and grain6.

• Consider the Table's Stability: Ensure the extensions will not compromise the table's stability6.

Methods for Extending Table Legs

Several methods can be used to extend wooden table legs, each with its own advantages and disadvantages.

Method 1: Adding Wooden Blocks

This is one of the simplest methods, ideal for straight, non-tapered legs6.

Materials Needed:

• Wooden blocks (matching the existing legs)6

• Wood glue3

• Screws3

• Clamps1

• Sandpaper1

• Finish (stain, paint, varnish)7

Step-by-Step Instructions:

1. Prepare the Blocks: Cut the wooden blocks to the desired height. Ensure the ends are square and smooth6.

2. Apply Glue: Apply a generous amount of wood glue to the top surface of the wooden block3.

3. Attach to the Leg: Position the block under the table leg, aligning it carefully3.

4. Clamp Securely: Use clamps to hold the block in place. Ensure the pressure is evenly distributed1.

5. Add Screws: For added stability, drive screws through the table leg into the wooden block. Predrill pilot holes to prevent splitting the wood3.

6. Let the Glue Dry: Allow the glue to dry completely, usually for 24 hours3.

7. Sand the Joint: Once dry, remove the clamps and sand the joint to create a smooth transition1.

8. Finish: Apply a finish that matches the existing table legs7.

Method 2: Using Threaded Inserts and Bolts

This method provides a secure and adjustable extension9.

Materials Needed:

• Threaded inserts9

• Hanger bolts9

• Wooden extensions (matching the existing legs)6

• Drill with appropriate drill bits3

• Wrench6

• Wood glue3

• Sandpaper1

• Finish (stain, paint, varnish)7

Step-by-Step Instructions:

1. Prepare the Legs: Drill a hole into the bottom of each table leg, sized appropriately for the threaded insert3.

2. Install Threaded Inserts: Screw the threaded inserts into the holes. Add a drop of wood glue for a more secure fit3.

3. Prepare the Extensions: Drill a hole into the top of each wooden extension, sized for the hanger bolts6.

4. Attach Hanger Bolts: Screw the hanger bolts into the wooden extensions9.

5. Join the Extension: Screw the wooden extensions into the threaded inserts in the table legs9.

6. Tighten Securely: Use a wrench to ensure the bolts are tightened, providing a stable connection6.

7. Sand the Joint: Sand any unevenness at the joint for a smooth transition1.

8. Finish: Apply a finish to match the existing table legs7.

Method 3: Creating Custom Wood Extensions

This method allows for a seamless and integrated look, ideal for more advanced woodworkers6.

Materials Needed:

• Wood (matching the existing legs)6

• Saw6

• Chisel6

• Wood glue3

• Clamps1

• Sandpaper1

• Finish (stain, paint, varnish)7

Step-by-Step Instructions:

1. Prepare the Wood: Cut the wood to the desired extension length. Shape the extension to match the existing table leg profile6.

2. Create a Tenon Joint: Create a tenon on the top of the extension that fits snugly into a mortise on the bottom of the existing table leg8.

3. Apply Glue: Apply wood glue to the tenon and inside the mortise3.

4. Join the Extension: Insert the tenon into the mortise, ensuring a tight fit8.

5. Clamp Securely: Use clamps to hold the extension in place while the glue dries1.

6. Let the Glue Dry: Allow the glue to dry completely, usually for 24 hours3.

7. Shape and Sand: Once dry, shape and sand the extension to blend seamlessly with the existing leg1.

8. Finish: Apply a finish that matches the existing table legs7.

Method 4: Using Slip-on or Adjustable Extenders

This is a quick and easy solution, though it may not offer the most seamless look6.

Materials Needed:

• Slip-on table leg extenders or adjustable table leg risers6

• Measuring tape6

• Cleaning supplies6

• Felt pads (optional)3

Step-by-Step Instructions:

1. Measure the Legs: Measure the diameter or dimensions of your table legs to ensure you purchase the correct size of extenders6.

2. Clean the Legs: Clean the bottom of the table legs to ensure a secure fit for the extenders6.

3. Install the Extenders: Slip the extenders onto the table legs, ensuring they are securely in place6. For adjustable extenders, adjust to the desired height and tighten the locking mechanism6.

4. Check Stability: Test the table for stability. Make any necessary adjustments to ensure the table is level6.

5. Add Felt Pads: Attach felt pads to the bottom of the extenders to prevent scratching the floor3.

Finishing the Extensions

Once the extensions are securely attached, finishing them to match the existing table legs is crucial for a cohesive look.

• Sanding: Use progressively finer grits of sandpaper to create a smooth surface1.

• Staining: Apply stain in thin, even coats, allowing each coat to dry before applying the next7.

• Painting: Use a high-quality paint and apply multiple thin coats for a durable finish7.

• Varnishing: Apply varnish to protect the wood and enhance its appearance7.

Ensuring Stability

Extending table legs can sometimes compromise stability. Here are some tips to ensure your table remains sturdy:

• Use Braces: Add cross braces between the legs to prevent wobbling4.

• Wider Mounting Plates: Use legs with wider mounting plates for better support4.

• Check Level: Ensure the floor is level and use shims if necessary1.

  
  

Common Pitfalls to Avoid

• Uneven Extensions: Ensure all extensions are the same length to prevent wobbling6.

• Weak Joints: Use strong joints and high-quality glue to ensure the extensions are secure3.

• Mismatched Materials: Choose wood and finishes that closely match the existing table6.

Relevant Questions and Answers:

1. Q: How do I choose the right wood for the extensions?
   A: Select a wood species that matches the existing table legs in color, grain, and texture. This will help the extensions blend seamlessly with the original table.6

2. Q: What tools do I need for extending table legs?
   A: Essential tools include a saw, drill, screwdriver, measuring tape, clamps, sandpaper, and finishing supplies. Depending on the method, you may also need a chisel, wrench, or threaded insert tool.6

3. Q: How can I ensure the extensions are stable?
   A: Use strong joints, high-quality glue, and consider adding cross braces between the legs. Ensure the floor is level and use shims if necessary.4

4. Q: Can I extend tapered table legs?
   A: Yes, but it requires more precise shaping and fitting. Creating custom wood extensions with a tenon joint is often the best approach for tapered legs.8

5. Q: What finish should I use on the extensions?
   A: Use a finish that matches the existing table. This may include staining, painting, or varnishing. Apply the finish in thin, even coats for the best results.7
