Measure the width and height of the door’s space with the tape measure to determine the size of the frame. Mark the height and the width of the door frame to the 2-by-4 boards.
Cut the 2-by-4 boards according to the measurements that you marked with a saw. If you need a heavier frame, cut two matching pieces for each side of the door frame and stack and nail them together.
Alternatively, you can also use 4-by-4 inch lumber.
Lay out the frame pieces on a flat, solid surface. Check if the pieces are even with a carpenter’s level.
Nail the frame pieces together with a nail gun.
Nail or screw metal braces across the corners of the frame. This will strengthen the frame and make it more sturdy.
Measure the width and height of your new frame to determine the length and number of planks you will use for the barn door. Mark the measurements on the 4-by-1 boards and then cut the boards accordingly.
Lay the cut 4-by-1 boards on the frame. Check if they’re straight using the carpenter’s level.
When you are sure of the placement, apply wood glue at the inner side of the door frame where the 4-by-1 door boards will be attached. Then affix the door boards and nail them into the frame.
Lay the sliding door track at the top of the door frame. The track should be positioned on the back side of the barn door.
Mark where the tracks will be attached. Use a carpenter’s level to make sure that the mark is straight.
Screw the metal track onto the frame.
Arrange the track wheels at the bottom of the frame and mark their placement. Screw the track wheels to the bottom of the frame.
Attach the other sliding door track to the barn wall. The placement of the track should match the track on the door.
Use a level to make sure that the tracks are even. Before attaching the track to the wall, check the placement with the carpenter’s level.
When you are sure, nail or screw the tracks to the barn walls.
