How to Build a Double Drive Cedar Gate

Building a double drive cedar gate is a fantastic DIY project that can enhance the security and aesthetics of your property. Whether you're replacing an old gate or installing a brand-new one, this project can be rewarding and add value to your home. In this guide, we'll walk you through the entire process of building a double-drive cedar gate, from post setup to the final finishing touches.

Why Choose a Cedar Gate?

Before we dive into the project details, let’s take a moment to discuss why cedar is a preferred material for gate construction. Cedar is a durable, naturally resistant wood that thrives in outdoor conditions. It is naturally resistant to decay and pests, making it an ideal material for gates and fences. Cedar also has a beautiful grain pattern, which gives the gate an attractive, rustic appearance. The wood ages well, maintaining its beauty while developing a silver-gray patina over time. For those looking for a low-maintenance, long-lasting gate, cedar is a perfect choice.

Materials Needed

• Cedar wood for posts and pickets (quantity depends on gate size)

• 2x4 lumber for gate framing and support rails

• T-hinges for better gate adjustment

• Galvanized chain-link drop rod for additional support

• Deck screws (3-inch screws recommended)

• Nailer strips for picket installation

• Lumber for bracing (2x4s)

• Concrete mix for setting posts

• Screws for hinge and latch installation

• Wood saw (Circular saw preferred)

• Drill and drill bits for pre-drilling screw holes

• Measuring tape

• Level

• Square or carpenter's square

• Angle grinder (for trimming)

• Paint or wood sealant for finishing

• Anti-sag kit to prevent gate sagging

Step 1: Preparing the Gate Location

Choosing the Right Spot for Your Double Drive Gate

The first step in building your double-drive cedar gate is selecting the appropriate location. You’ll need to ensure that the area is level and free from obstacles like large rocks or trees. If the ground is sloping, consider how the gates will open. Ideally, the gates should open outward without dragging along the ground.

Start by measuring the width of the opening where the gates will be installed. A typical double drive gate consists of two gate leaves, each roughly 4 feet wide, making the total width around 8 feet. However, the size can be adjusted based on your needs and the space available.

Setting the Posts

Once you've chosen your location, you’ll need to set your gate posts. Begin by digging two post holes, ensuring they are deep enough to support the weight of the gates. The depth of the hole should be at least 2 feet for a sturdy base, especially in areas where heavy snow or ice can accumulate.

Next, place your posts in the holes and ensure they are level. You may want to use a level or plumb bob to make sure the posts are perfectly vertical. Once the posts are positioned correctly, fill the holes with concrete, ensuring the posts stay straight while the concrete sets.

After the concrete has dried (usually about 24 hours), cut the posts to the desired height. If you live in an area with heavy snow, consider adding an extra 2 inches to your post height to ensure that the gates have enough clearance when they swing open.

Step 2: Assembling the Gate Frame

Cutting and Preparing the Rails

Now that your posts are set and secure, it’s time to build the frame for your gates. The frame consists of horizontal rails that will hold the pickets in place. For this project, we're using 2x4s for the rails.

Begin by measuring the width between your posts, accounting for a small gap between the gate and the posts for smooth opening and closing. Once you have your measurements, cut the rails to length. You'll need two rails for each gate: one for the top and one for the bottom. If you’re building a gate wider than 8 feet, you’ll need a center support rail to prevent sagging.

Make sure to check the fit of the rails before securing them. The rails should be positioned slightly above the ground to prevent them from dragging, and they should be level to ensure the gates swing properly.

Installing the Rails

Once the rails are cut, it’s time to attach them to the posts. Begin with the top rail, which should be positioned 27 inches from the bottom of the posts. Secure the top rail with screws, making sure the rail is level.

Next, attach the bottom rail 54 inches from the top of the posts. This measurement can vary depending on the size of the gate, but this placement ensures that the bottom rail is sturdy enough to support the gate’s weight.

Step 3: Installing the Pickets

Selecting the Right Pickets

The pickets are the vertical slats that make up the bulk of the gate’s appearance. Cedar pickets are a great choice because they are durable, weather-resistant, and visually appealing. Choose pickets that are about 5 inches wide, or adjust based on your personal preference.

You can opt for a classic style with evenly spaced pickets, or for a more unique look, consider overlapping pickets for added privacy.

Cutting the Pickets to Size

Once you've decided on the spacing for your pickets, it’s time to cut them to size. To avoid wasting material, measure the width of the gate and determine how many pickets you’ll need to cover the frame. For a standard 8-foot gate, you'll need around 18 pickets.

You can either leave the pickets at their full length or trim them to fit perfectly within the frame. When trimming the pickets, it’s important to measure carefully to avoid gaps or an uneven look. If necessary, rip the pickets to a consistent width using a table saw.

Attaching the Pickets

Now that the pickets are cut, it’s time to attach them to the gate frame. Start with the top picket and use a level to make sure it’s perfectly vertical. Attach it to the top rail with screws, then move on to the remaining pickets. Maintain a consistent gap between each picket, typically around 1 inch.

If you find that the pickets are too tight or too loose, make adjustments to ensure the spacing is uniform. For a clean look, make sure the pickets are securely fastened to both the top and bottom rails.

Step 4: Installing the Hinges

Choosing the Right Hinges

For this project, we're using T-hinges, which are ideal for heavy gates and allow for easy adjustment. T-hinges are designed to bear the weight of the gate and provide stability. They are perfect for double-drive gates where each gate leaf needs to swing independently.

Measure and mark where the hinges will be placed on the gate and the posts. Typically, the hinges are installed about 10 inches from the top of the gate and 10 inches from the bottom.

Attaching the Hinges

Before installing the hinges, it’s important to ensure that the gate frame is fully square and level. Once you’re satisfied with the gate’s positioning, attach the hinges to the posts first. Then, attach the other side of the hinge to the gate. Ensure that the gate swings open and closed without obstruction.

Step 5: Installing the Drop Rod and Latch

Adding the Drop Rod

A drop rod is essential for securing one side of the double drive gate when it is closed. This rod slides into a receptacle embedded in the ground, keeping the gate stationary.

To install the drop rod, measure the desired position on the gate and attach a galvanized bracket. Secure the rod in place, making sure it’s long enough to reach the ground easily. A heavy-duty drop rod will provide added security and durability compared to standard models.

Installing the Latch

Next, install the latch on the stationary gate. Be sure to leave enough space for the latch to function smoothly, and always account for hardware clearance. A properly installed latch ensures that your gate remains securely closed when not in use.

Step 6: Final Adjustments and Finishing Touches

Checking for Alignment

Once everything is installed, check the alignment of the gates. They should swing freely without dragging on the ground. Adjust the hinges if necessary to ensure proper function. You may need to slightly raise or lower one side of the gate to ensure both gates align evenly.

Sealing the Gate

To protect the cedar wood from the elements, it’s important to apply a wood sealant or stain. This will help preserve the natural beauty of the wood while providing protection against moisture, UV rays, and other environmental factors. Apply the sealant evenly across all surfaces, allowing it to dry completely before use.

Conclusion

Building a double drive cedar gate is a rewarding project that can enhance both the functionality and beauty of your property. By following the steps outlined in this guide, you'll be able to create a durable and attractive gate that lasts for years to come. With careful planning, attention to detail, and the right materials, your cedar gate will be a perfect addition to your home.
