  • Pencil

  • Caulk gun

  • Construction adhesive

  • Miter saw

  • 2-by-6-by-8-foot boards

  • 3 2-by-4s

Make your wood gate twice as wide to accommodate large machinery.

A yard enclosed by a sturdy fence is a safe place for kids and pets to play. Most yards have a 36-inch-wide fence for accessing the yard. However, anyone who has a large lawn tractor or a trailer needs a larger gate. The do-it-yourself handyman can construct a double gate to allow access for large equipment.

Step 1

Measure the gap between the two posts to calculate the size of the gate, using a tape measure.

Step 2

Cut 2-by-6-by-8-foot boards to 6 feet, using a miter saw. This is the typical height of a privacy fence. Change the height as needed to match the height of your fence.

Step 3

Set a 45-degree bevel bit into a router table. Adjust the height of the router bit to cut a bevel on each of the 2-by-6s used in the two gates. This provides an attractive detail for the gate.

Step 4

Lay out each gate on a flat surface just as it will be assembled. Measure the width of each of the gates. Cut two 2-by-4s to the width of each of the gates. Theses are for the horizontal supports for the gates. Apply a strip of construction adhesive to each of the 2-by-4s. Use a caulk gun for this. Attach a board 9 inches from the top and bottom of each gate. Make sure is it is perpendicular to the 2-by-6s. Use a framing square to check this. Place two 2 1/2-inch wood screws through the 2-by-4 into each of the 2-by-6s.

Step 5

Place a 2-by-4 diagonally across the gate from the top to bottom. Align the outside edge of the diagonal board with the outside edge of the horizontal supports. Draw a line on the 2-by-4 to show where it needs to be cut to fit between the two horizontal supports. Apply construction adhesive to the diagonal 2-by-4 and screw it in position in the same manner as the last step.


Use heavy-duty hinges to support the gate and keep it from sagging over time.
