ATTACH THE UPRIGHTS AND ARM REST.
1. Cut the back uprights (A) and front uprights (B). Make a round profile cut at the tops of the back uprights, using a jig saw. Attach the uprights to the outside faces of the seat supports, flush with the ends of the supports, using glue and 2 1/2" screws.
2. Round the bottom front corners of the front uprights and bottom rear comers of the back uprights with a sander, so they are flush with the seat supports.
3. Use 2 1/2" screws to attach arm rails between the uprights, flush with the tops and with rope holes aligned.
4. Slide the back slat assembly behind the seat assembly (photo F).Attach the back cleat to the back uprights with 3" screws, so the upper rear corners of the cleat are flush with the back edges of the uprights, 3" down from the tops of the uprights. Make sure the back faces of the back slats are resting against the top front edge of the rear stretcher.
