1.) The arbor posts
Dig four holes 350mm (14") square by 600mm (24") deep. Position the holes as shown in the
Arbor plan. Concrete the posts in place and wait until the concrete cures (usually the next day) before cutting the tops of the posts to suit.
There is a detailed description of how to position the posts, mix and pour the concrete, and cut the top of the posts (including the rebate), in the
Garden pergola construction page.

2.) Cut and trench the arbor beams
Mark and trench (checkout, rebate) the two beams. The dimensions are shown in the
Arbor plan page.
This can be achieved by setting the blade on a circular saw to the required depth and making repeated saw cuts across the beam where the trench is to go.
Finish by chiseling out the grooves with a sharp chisel. The more saw cuts, the easier the chiseling.

3.) Position the arbor beams
Bolt the beams to the top of the posts with 12mm (1/2") galvanized coach/carriage bolts. Use two bolts at each meeting, eight in all. (See picture.)
