I m wrapping up a project for a client an.
How to build a outside barn door.
Measure from the floor to the top of the door casing then cut the boards inch shorter on a miter saw.
This includes the hardware and track.
If needed you can substitute 1x10 t g boards for 1x8 1x12 or even 2x6 or 2x8 boards.
Square up the assembly with longer strapping at the top and bottom edges.
Gang the boards side by side place the blocks along the outside edges and use long bar clamps to cinch them together.
Measure from both corners of the door before screwing the middle rail to the stiles.
It s time to assemble the frame of the barn door.
If you want to cover the opening with one door you ll need an area on one side of the opening that s wide enough for the door.
To do this we started by gluing and screwing the bottom rail to both sides stiles.
This will ensure that your door is square.
Next glue and screw the bottom mullion to the bottom rail and middle rail.
Before you start shopping for barn door hardware take a careful look at the area where you would like to install the barn door and figure out what door setup works best.
