Step 5. The end wall frames
This is pretty much measure, cut, and fix as you go.
Before you start, ensure the side walls are plumb (vertical).
For all wall framing lumber, use 1 1/2"x 3 1/2" (90mm x 45mm) treated, or natural decay-resistant lumber.
Cut the door studs to size and fix in place. They should be 36 3/4" (920mm) apart to allow for the door.
Cut the door head to size and fix in place. It should be 72 3/4" (1820mm) above the base to allow for the door
Cut the top plates to size and fix them in place.
Cut the bottom plates to size and fix them in place.
Measure, cut and fix the bracing members.
Step 6. The doors
Make two doors as per above dimensions.
The front door and the back door.
Make the doors 3/4" (20mm) smaller than the opening.
Use 1 1/2" x 1 1/2" (45mm x 45mm) stock for the stiles (side upright pieces), and use 1 1/2" x 3 1/2" (90mm x 45mm) stock for the three horizontal rails.
Make the door frames up on a flat surface. Ensure the frames are square and then nail the gussets in place on both sides of the doors.
Hinge the doors in place and fit handles or padbolts of your choice.
