2. Unclamp the pieces and drill 3/8" holes for lag screws through the legs, using the pilot holes as center marks.
3. Apply moisture-resistant glue to the ends of the stretchers. Attach the legs to the stretchers by driving lag screws with washers through the legs and into the stretchers. Use the same procedure to attach the spreader to the stretchers.
ATTACH CLEATS AND RAILS.
1. Cut the side rails (G) and end rails (H) to length. Drill two evenly spaced, 1/8" pilot holes through the ends of the side rails. Counterbore the holes 1/4" deep, using a counterbore bit. Apply glue and fasten the side rails to the end rails with 2" deck screws.
2. Cut the end cleats (D), cross cleats (E) and side cleats (F) to length. Fasten the end cleats to the end rails 3/4" below the top edges of the rails with glue and 2" deck screws (photo B). Repeat this procedure with the side cleats and side rails.
