Cut the two, 2x8x8's treated boards into four, 3.5 feet boards

Cut the treated fence post into four, 20" sections (the four corners) and two, 16" sections. (two support braces in the middle of each bed)

Use the 20" fence posts as the base for your corners. Starting with a long 2x8x12 board, line it up flush to the corner of the post and secure to post using lag bolts screwed into place with an impact hammer or socket wrench.

Do the same thing with the 3.5 foot board on the other corner. Continue for all bottom boards, making sure you stagger the lag bolts so you dont hit one with the other when making the corners.

Lastly, connect the two, 18" posts into the inside of the bed, directly in the centers of the 2x8x12 boards. See pictures in blog post.

The posts on the ends of the four corners of the beds stick up 4" above beds. These are meant to be placed into the ground, securing bed into place. Essentially you made the bed upside down, and it will need to be flipped when putting into place.
