See Instructions Good Choices of Lumber for this table are Cedar or Exterior Grade Pine Additional Materials - # 8 x 3 Exterior Wood Screws - #8 x 2 ½ Exterior Wood Screws - Kreg Outdoor Screws #8 x 2 ½ - Pocket Hole Plugs (Optional) - Gorlilla Glue (Polyurethane) (Optional) - TiteBond II or Tite Bond III Wood Glue 3

4 Building the Cross Frames 1. Cut the left & right seat frame parts (A) and the left & right table frame parts (B) to length. (As shown in figures 1 & 2). Cut a 22.5 / 67.5 degree angle on each end of parts (A & B), the final length of each frame piece is measured from the long points of the angles as shown. Next cut the eight spacers (C) to size. (See Figure 3) Figure 1 Figure 2 Figure 3 4

5 Building the Cross Frames (Continued) 2. Mark out the Centered notches on both faces of the Seat Frame Parts (A) and Tabletop Frame Parts (B) As shown in Figure 4. (It is recommended to measure the combined with of the frame parts and spacers when sandwiched together to obtain the notch width. You want the mating notching to fit firmly when assembled) *To make your notches you can use a variety of methods (On the table saw using a single blade or dado stack, with a circular saw making multiple kerf cuts and cleaning up with a chisel, with a hand saw and chisel. Each of these methods is affective and will work. Figure 4 3. Working on a flat surface group the frame parts side by side with the notches facing upward while aligning the ends of the boards and the notches. This will allow you to inspect the notches to ensure they are all uniform in size and the bottoms of the notches are flat. Clean up with chisel if needed. 4. Next test assemble the interlocking seat (A) and table (B) cross frames fitting the spacers where shown in figure 4. If your fit is satisfactory, disassemble, and use exterior wood glue in the joints, reassemble the frame parts and secure using #8 3 exterior wood screws vertically to join the frame pieces. Drive #8 3 wood screws through the frame sides and into the spacers in a diagonal orientation. Repeat this for all sides and for both the Seat (A) and Tabletop (B) cross frames. *For visual appeal and added protection, you may want to countersink the screws and plug with a matching wooded plugs. (Optional) 5

6 Making & Assembling the Seat Bases 1. Using 5 ½ x 1 ½ Stock Cut the Table Legs (D), Seat Bases (E), and Seat Legs (F) to length with the angles (shown in Figures 5 7.) Figure 5 Figure 6 Figure 7 6

7 Making & Assembling the Seat Bases (continued) 2. Clamp a Seat Base (E) to the side of your bench. Place a Table Leg (D) against the Seat Base (as shown in Figure 8.) Next Using a Seat Leg (F) mark out a line on the Table Leg (D) and transfer that line to all 4 sides of the Table Leg. Figure 8 3.

8 Making & Assembling the Seat Bases (continued) Figure Now for this step a bench vise comes in handy, but is not necessary. You want to center the table leg between the two seat legs and attach the table leg to the seat base ensuring the back of the leg is flush with the back of the base (as shown in figure 10) If using a bench vise, secure the table leg using the line that was drawn on the leg in step 2, this will position the leg in the appropriate orientation so you can invert the base assembly and secure the leg using 3 screws from the bottom side be sure to pre drill and countersink for the screws. NOTE: the seat spacers clamped to the seat base will help with centering the leg (as shown in Figure 11) Figure 11 Next cut 8 seat cleats glue and screw them with 2 ½ screws to the inside face of each seat leg extending them 7/8 past the outside edge of the legs and flush with the top of the legs (as shown in Figure 10 above) 8
