Things You'll Need:
- Circular saw
- 4-inch by 4-inch posts
- Post-to-beam brackets or post cap
- Jigsaw
- Plywood template
- Ladder or stepladder
- Bolts and washers
- Knee braces
- Reciprocating saw
-
Step 1
Trim your posts to the same level to make sure they're exactly the same length. Use a circular saw to cut the posts to the right length.
-
Step 2
Install a post-to-beam connector or a post cap to the top of each of the beams. Make sure these connectors are installed securely.
-
Step 3
Trim the beams to be the appropriate lengths.
-
Step 4
Cut decorative shapes into the ends of the beams if you wish. Do this now, before you lift them into place. You can make a design by using a jigsaw and a piece of plywood to create a template. Then trace the template onto the end of the beam, and cut it with a reciprocating saw.
-
Step 5
Put the beams into place by lifting the end of each beam onto a stepladder. Use a second stepladder to lift the end of the beam into the bracket on the top of the post. Do the same for both ends.
-
Step 6
Bolt the beams securely into place with the post brackets.
-
Step 7
Place knee braces securely on the outside corner posts.
