Step 3Start Screwing Stuff Together
Use 3" screws and don't forget to pre-drill.
You should use between 2 and 3 screws at each joint, we don't want this falling apart.
Next, use your lag bolts to connect the 4x4's to the base of the frame.
You're going to need to pre-drill these, otherwise you'll never get them in the wood.
You' should use two bolts per post, one through the side of the base frame, and the other through the "indented" 2x4.
Cut four 88" pieces of 2x4 to use as the back braces. You'll need to miter them by 60 degrees on one end.
Once they're cut, you can make two pairs of them by screwing two of them together - then screw them into the frame. Remember: Pre-drill!
Cut four 1' pieces of 2x4 as corner braces, and miter them by 45 degrees on both ends. Screw them into the corners of the frame. (See pictures)
