Each A-frame support for the table consists of:
1 piece of 2×6 seat support
1 piece of 2×4 tabletop support
2 pieces of 2×6 legs
Assembling the A-frame support
1. The above image shows the side view of one of the A-frame of the deck table and its individual parts on right. There should be a width of 52 ¼ inch between the bottom outer sides of the leg support, while the top outer sides should be 23 ½ inch which will sit flush with the table top support.
2. Cut the table top support at a 60 degrees angle with using protractor 2 inch below the top surface. Do the same with the seat support but at a mark 3 inches below the surface of the seat.
3. Height from ground to bottom of the seat support is 9 ½ inch. Cut the 2×6 leg support at a 60 degrees angle by marking it with the protractor and saw.
4. Clamp these pieces together and drill 1/8-inch pilot holes through the clamped supports and legs. Use these pilot holes to drill recesses about ½ inch deep for the bolts. Do not drill these recesses all the way through the legs.
5. Secure with nuts, bolts and washers.
6. Complete the other A-frame.
Assembling the seat and top
1. There should be four seat boards and five tabletop boards measuring 48-inch each (2x6s).
2. Mark a squared vertical line 8 ¾ inch from both ends of each board.
3. Mark two screws about 1 inch from the top and bottom edges on the vertical line you just drew and drive the screw part way.
4. Get someone to help you hold up the two A-frame support. Then, attach one seat boards (the outer board that is flush with the seat support) to both of the A-frames. Do not screw it in tightly as yet. Attached the other outer seat board on the opposite end then use a framing square to make sure the seat supports are perpendicular to the seat boards. Make adjustments if they are not.
5. Once they are square, drive in each of the remaining screws.
6. You can now attach the inside seat boards, making sure there is a ¼ inch gap between the inside and outer boards.
7. Attach the tabletop boards. Make sure that the outside edges are flush with the edges of the tabletop supports and keep a 1/4-inch gap between the boards
Center brace and diagonal braces
- Cut the center brace 27 inch long with its ends cut to a 45 degree bevel.
- Measure and mark the center of the table and the center of the brace.
- Screw the brace to the center of the tabletop.
- For the diagonal brace, use a cardboard template to transfer measurements to the 2x4s.
- Cut the diagonal brace then screw them beneath the table, with screws driven at an angle through the braces into the seat support and tabletop.
