We built one of the six picnic tables for our 2012-2013 engineering class at Aragon High School. This Instructable will walk through the process of building our picnic table. Our picnic table is made out of redwood and measures 54"x63.5"x35". This table can be used for picnics, gatherings, and other events or gatherings. The original schematic and parts list are included as you are welcome to make a table of your own. If you have built a saw horse before, this project will be extremely easy. Depending on your experience, this project may take between one to three weeks.
Here is a list of the materials we used:
Drill and Drill Bits
5 2x6 Redwood
4 2x4 Redwood

We started with 3 long 2x6s and cut them in half using a chop saw to get six 54 inches 2x6s.
We then laid them flat separated by 1 inch. Total width was 35.5 inches. I know that doesn't add up. It’s because some of the 2x6’s were 2x5.5.
We then took a long piece of 2x4 and cut it to exactly 35.5 inches with the chop saw and screwed it to the set of six 2x6s. We used two screws per plank. The screws were carefully lined up to be in a straight line. All of them are equally distant from the edge of the plank they are on.
We took four 2x4s and cut them to be 33 inches long with the chop saw. These were the legs. The legs were cut to be parallelograms.
We used the chop saw to cut the edges of the legs to be 45 degrees. This allowed the legs to have a 45 degree angle when attached to the bottom of the table.
We bolted the legs to the table using 3.5 inch bolts. We used a rubber mallet to push it in 9/10 of the way and a wrench to tighten the rest.
We then took two more pieces of 2x4s and cut them to be 62 inches using the chop saw again.
We bolted those to the table to be 13 inches from the top of the table using 5.5 inch bolts. These were used to support the benches.
We then cut two long 2x6s into four 54 inch planks. These were put on top of the 62 inch wood mentioned in Step #8. These are the benches.
We attached them to the 2x4s using screws on top. These were placed parallel to the table top but on a lower plant 13 inches lower.
We then cut one 2x6s in half to make 2 2x3s that were 52 inches long with the table saw.
We then attached the 2 52” 2x3’s at the bottom of the legs of the table. This provided support and balance so the table could not flip. It acted much like how a foot supports a human body.
Using a chop saw, we cut an 18” 2x4 as a centerpiece.
We then cut a long piece of 2x6 into a 23” 2x6 using a chop saw.
We cut this in half to make 2, 23” 2x3’s using a table saw.
We cut the tips to be angled 34 degrees.
We attached this from the the wood in step#8 to the center piece as support to prevent the table from moving side to side.
We then used the sanders to clean the wood and get rid of any undesired parts.
After everything is steady and tight, we covered every inch of the table with teak oil to make it more resistant to tough weather.
