DIY Extra Long Wood Bench Instructions:

1. First, build the three legs:

• Cut six 2×4 boards to 14″ long end to long end with each end cut at 45 degree

angles from the 3 ½″ side of the boards (see image below)

• Cut three 2×4 boards to 11 ¼″, long end to long end with each end cut at 45

degree angle from the 3 ½″ side of the board

• Cut six 2×4 boards to 12″ in length each.

A. Assemble the legs. For each leg, attach two 2×4 12″ boards to the top of one of

the 11 1/4″ boards with angles cut at each end. Use a countersink drill bit to

pre-drill holes into the bottom of the 11 1/4″, then add wood glue and attach the

12″ 2×4 boards with 2 ½” exterior wood screws.





B. Next, attach a 14″ 2×4 board on top of the two 12″ 2×4 boards. Again, pre-drill

with a countersink bit through the top of the 14″ board, and then attach with

wood glue and 2 1/2″ wood screws.

C. Attach another 14″ 2×4 to the bottom of the 11 1/4″ board. As before, predrill

through the underside of the 14″ board with a countersink bit. Then attach with

wood glue and 2 1/2″ exterior wood screws.





D. Now it’s time to create the diamond design in the center of the legs (this

matches the diamond design on the outdoor table that this bench is designed to

match).

1. To do this, instead of calculating angles, mark the center point of each

side of the rectangle in the center of the legs:

2. Next, hold a 2×4 so that it sits diagonally across the marks and using a

pencil, mark the underside of the board to determine where to make the

angle cuts.





3. Once all four sides of the diamond are cut, attach them using wood glue

and 2 1/2″ exterior wood screws. (Pre-drill all holes with a countersink

bit). Attach through the sides of the legs and through top board of the

legs. – the two lower boards will only be attached at the bottom by wood

glue, only the top of those boards are screwed into place.





4. The three legs should now look like this:

2. Construct the top of the bench.

A. Cut four 2×4 boards to 108″ in length each.



B. Drill five 1 1/2″ pocket holes into one of the long sides of three of the four

boards.

C. Use wood glue and 2 1/2″ exterior (blue kote) pocket hole screws to attach the

four boards together.

3. Build the frame.

A. Cut six 2×4 boards to 45″ in length each.

B. Drill two 1 1/2″ pocket holes into each end of one side of the board.



C. Using wood glue and 2 1/2″ exterior pocket hole screws, attach two 45″ boards

between each of the legs (the boards should attach right before the angle cut on

the 14″ boards):

D. Cut eight 2×4 boards to 4 3/8″.

E. Drill three 1 1/2″ pocket holes into one side of each 4 3/8″ board (drill two

pocket holes in one direction, and drill the third pocket hole in the opposite

direction):



F. Use wood glue and 2 1/2″ exterior pocket hole screws to attach the 4 3/8″

boards to the 45″ long boards making up the frame:



G. Attach the two 45″ boards across the bottom portion of the legs. Using wood

glue and 2 1/2″ exterior pocket hole screws, attach one 45″ 2×4 in the center of

the legs (attach to the 11 1/4″ board making up the bench feet):



4. Attach the bench seat top.

A. Center the frame on the underside of the bench top. Using a countersink drill

bit, drill several holes through the underside of the frame along the length of

the bench.

B. Using wood glue and 2 1/2″ exterior wood screws, attach the frame to the

bottom of the bench seat.



5. Cut and attach the cross support boards.

A. Because they have very odd angles, use the same method described above to

mark the angles. Hold the 2x4s in the location they will be attached, and from

behind, mark the location where the angles should be cut for the boards to fit

properly.

B. Attach the boards, first using a countersink drill bit to predrill the holes, then

using wood glue and 2 1/2″ exterior wood screws.

6. Perform finishing touches.

A. Fill visible holes with wood filler or pocket hole plugs, and let dry.

B. Sand the bench until smooth.

C. Stain with Dark Walnut (or stain color of choice) and let dry completely.

D. Apply a minimum of three coats of Spar Urethane Exterior finish.
