You have done a really good job on your woodworking projects. This is coming from an old shop teacher. One hint that may save you some work in the future. On the deck sections, you need to put a ledger strip under the deck top that you screwed into the ends. Just rip a salt treated board into 3 equal widths and secure inside the sections. Salt treated is known for cracking and if the board slides down, it is a bugger to pull back up. I loved your project and hope you the best in the future.
