How to Make Table Extension Slides

Table extension slides are a popular type of furniture hardware used to extend the length of a table. They can be easily installed on an existing table, making them a convenient and cost-effective way to increase the seating capacity of your dining or conference table.

How to Make Table Extension Slides

In this guide, we will walk you through the process of how to make table extension slides from scratch. With just a few basic tools and materials, you can create custom-made table extension slides that perfectly fit your table and match its design. Whether you are a DIY enthusiast or a professional woodworker, follow these steps to make your own table extension slides.

Understanding Table Extension Slides

Before we dive into the steps of making table extension slides, let’s first understand what they are and how they work. Table extension slides consist of two pieces – a stationary base and a sliding top piece. They are usually made from metal or wood, with ball bearings or rollers for smooth movement.

The base is attached to the underside of the table, while the top piece is attached to the leaf (the additional section of the table). When not used, the top piece slides underneath the base and is hidden from view. The top piece can be pulled out and aligned with the table, effectively increasing its length.

Table extension slides come in different sizes and weight capacities, so choosing the right one for your table is important. You can find them at hardware stores or online retailers.

Tools and Materials You Will Need to Make Table Extension Slides

1. Measuring tape

2. Table saw or circular saw

3. Drill

4. Screws

5. Wood glue or metal adhesive (depending on the material of your slides)

6. Sandpaper

7. Lumber (or any other material of your choice for the sliding top piece)

8. Metal or wooden sliders (depending on your preference)

Step-by-step Guidelines on How to Make Table Extension Slides

Step 1: Measure the Table and Cut the Sliding Top Piece

Measure the Width and Length

Measure the width and length of your table. Add 2 inches to each measurement to ensure a comfortable slide fit. This extra space will allow easy movement of the top piece without it being too tight or loose.

Cut the lumber into two pieces according to your measurements using a table or circular saw. Sand down any rough edges for a smooth finish. Measuring and cutting accurately is crucial for a well-functioning table extension slide.

Step 2: Attach the Sliders to the Top Piece

Align the sliders on each end of the top piece and mark where you will attach them with screws. Drill pilot holes at these marks and then screw in the sliders. Ensure they are securely attached, as they will bear most of the weight when the table is extended. If using metal sliders, you can use metal adhesive instead of screws for a cleaner look. Make sure to follow the adhesive’s instructions carefully.

Step 3: Attach the Base Piece to the Table

Attach the base piece to the underside of your table using screws or wood glue (depending on the material). Make sure it is level and secure. The base piece’s placement should allow enough space for the top piece to slide in and out smoothly.

Attach the Base Piece

While attaching the base piece, keep in mind the weight capacity of your slides and the material of your table. This will ensure that the table extension slides can support the weight of your extended table without any issues.

Step 4: Test and Adjust

Before using your new table extension slides, give them a test run to ensure they function properly. If you notice any issues or the top piece is not sliding smoothly, adjust accordingly. It might take some trial and error to get it right, but it will be worth it. This is also a good time to make final adjustments or sand down rough edges.

Following these steps, you can make your own table extension slides and save money while customizing them to fit your specific needs. With just a few tools and materials, you can create functional and durable table extension slides that will enhance the functionality of your table. So, next time you need more seating space for a gathering or a meeting, you’ll be prepared with your DIY table extension slides. Happy building!

Things You Should Consider to Make Table Extension Slides: furniture hardware

1. The first thing to consider when making table extension slides is the type of wood you are using. Different types of wood have different levels of strength and durability, which will affect the overall quality and functionality of your table extension slides. Hardwoods like oak, maple, and cherry are recommended for their strength and ability to withstand weight and constant use.

2. Another important factor to consider is the wood size and thickness you use for your table extension slides. The thicker the wood, the stronger and more durable your slides will be. Using at least 3/4 inch thick wood is recommended for optimal strength.

3. The type of joinery used in constructing your table extension slides is also crucial. Dovetail joints are known for their strength and are commonly used in high-quality table slides. Other types of joinery, such as mortise and tenon or dowel joints, can also be used but may need to be stronger.

4. Choosing the right hardware for your table extension slides is essential for smooth operation and longevity. Heavy-duty metal ball-bearing slides are recommended for their strength and ability to handle heavy-weight loads. Alternatively, you can use wooden slides with built-in stops for a more traditional look.

Choosing the Right Hardware

5. Consider the length and width of your table when designing your extension slides. The length should be at least three-quarters of the table’s total length to ensure stability and proper support. The width should also match the table’s width to avoid any gaps or unevenness.

6. Proper installation is key to the functionality and longevity of your table extension slides. Make sure to follow manufacturer instructions carefully and use the correct size screws for secure attachment.

7. Regular maintenance is important for keeping your table extension slides in top condition. Lubricate the slides with a silicone-based lubricant every few months to ensure smooth operation. Also, periodically check for any loose screws or wear and tear on the slides.

8. Finally, consider the design and aesthetics of your table extension slides. They should complement the overall look of your table and blend in seamlessly. You can choose from various finishes and styles to match your personal preference and decor. 

Following these considerations will help you create high-quality and functional table extension slides that will enhance the usability and longevity of your table. With the right materials, hardware, and installation, your table extension slides can provide a seamless and convenient way to extend your table for larger gatherings or events.

So, take your time designing and constructing your table extension slides to ensure they meet your needs and requirements.  So, it is essential to take utmost care in selecting the right furniture hardware. The above-mentioned points will help you make an informed decision and create table extension slides that are durable, functional, and aesthetically pleasing. Good luck!
