Erecting this structure takes only a couple of days, several days apart: one to dig postholes and set the posts, another -- after the concrete cures -- to cut and assemble the components. We used pressure-treated 4x4s for the posts and, to add to the beauty of the arbor, redwood for the superstructure.
What You Need:
- 2 10-foot 4x4s (all lumber is cedar or treated)
- 4 18-inch 2x6s
- 2 6-foot 2x6s
- 40 2-foot 2x2s
- Galvanized or stainless steel fasteners (at least 3 inches long)
1. Erect two posts. Sink the 4x4s approximately 5 feet apart, setting them at least 2-feet deep, or down to the frost line. Secure with concrete or packed soil. Cut off so the tops are approximately 7 feet above ground level. Lag-screw two short lengths of 2x6 to each post. Check to be sure crossbeams are square with the posts before tightening screws.
