Introduction: Sleek Picnic Table With Detached Benches
We finally got our back patio built and all that was missing was a table. Rather than spending a boat-load of money on one that kinda worked for us, I decided to just build one. So here we are. I actually used two picnic table Instructables as my sources and just modified them to fit my needs. The first one had the idea of detached benches that I really liked. The second one added a couple simple design elements that were real sleek. With elements from both of these, I set out to create a combination of the two. I intend to show you the process of how I constructed mine rather than the precise measurements of each cut. I am an amateur woodworker with only common sense and some basic tools. I will also show you some things that I learned from. You should take this template and make your own creation. For even more detailed pics, just click the i in the upper left hand corner of any photo. Feel free to comment, and if you have any questions I'll try my best to answer them. A big thanks to the Instructables community for this project. Below is a video of how much wobble this table has. I really think there should be more of these demos for people to see how to improve others' designs. Good Luck!!

Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Gather Materials and Tools
My table is 8ft. long. Feel free to adjust to your preference. Also of note, the material list below is what I used, not necessarily what I would recommend. For example, my table legs are 2x4s, but I recommend you use 2x6s to prevent some wobbling. I'll let you know if I recommend something over what I used.
-small spacer (about 1/4" - 1/2" wide)
-skil saw (miter saw recommended, but I already had a skil saw)
-5/16" drill bit (at least 6" long)
-7/8" drill bit
-clamps (helpful if working alone)
-sandpaper (belt sander recommended) 40-50 grit and 120 grit
-1/2" wrench and 1/2" ratchet
-small pressurized sprayer (for the sealer/stain)
-wide (2") foam brush
-22 Cedar 2x4x8
-2 Cedar 2x6x8
-2 lbs. 2" tan deck screws
-16 Fully threaded 5/16-18 bolts (5 1/2" long)
-16 Fully threaded 5/16-18 bolts (1 1/2" long)
-64 5/16" washers
-stain/sealer (optional, but recommended)
Step 2: Create Table Underside
I went with 7 2x4s as my table top. Lay them out with your coloring and good sides as the top in mind. Turn them upside down so you install the legs and supports easily. I found it easier to drill them in from underneath so I could align the supports properly. Use the spacer to space out your 2x4s...it's waaaay easier than trying to measure everything. Plus it's more consistent. Each support for the legs consists of two 2x4s cut off at a 45° angle on each side. One screw is placed through the topside of each 2x4. On the table, there will be 5 of these identical supports that need to be cut...two for each set of legs and one in the middle for the brace that will go there. My 2x4s didn't come out to the exact same length, as seen in second photo. Just be aware of where you are measuring from. I also would recommend making your miter cuts before assembling the table. I used my skil saw once everything was screwed together and it was just a pain in the ass.
Step 3: Create & Install Table Legs
The length of the table legs will depend on the height you want the table. We know how wide the table is and you just need to decide how high you want it. Once you know how high you want it, use the Pythagorean Theorem to figure out how long you need to cut the legs.
This next part is kinda tricky, but it's a lot easier than I thought it would be. In order to make the legs of the benches and table look like they run into each other, here's what ya do. Each leg will essentially have a chunk cut out that is halfway through, that way when they are put in the "X" pattern, they are seamless. It takes some precise cutting, so be patient with this part. Measure where your legs will cross over each other. Using a hacksaw, cut out that section of each leg. I used 2x4s even though I got 2x6s strictly for this purpose. I got caught up in the process and forgot I had them.. I would highly recommend you use the 2x6s for the table legs to decrease the side-to-side wobble. Drill your holes. 2 in the "X" part of the legs and 1 on each part that connects to the underside of the table supports we just created. You'll want to sink the nuts and bolts in the wood, so drill your smaller 5/16" bit all the way through and use your larger 7/8" bit to carve out just enough space beneath the surface to fit a nut or the face of a bolt. Put a washer on each side and tighten it all together.
Step 4: Insert Braces and Center Beam
For added stabilization, I used these braces to prevent dramatic side wobble. It worked pretty well. The only wobble I get is from the section that runs from the ground to the brace as a result of the small 2x4s as the legs, which is why I recommend the 2x6s instead. For my braces, It measured out to be a 19° and 71° cut. Two screws into the outside of the cross section of the legs and then two into the center support should do the trick.
Step 5: Create Benches
This step is actually going to be nearly the exact same as the table. The supports and legs are the same design as the table, so just use the plans Steps 2 & 3 to create the benches. I used the 2x6 as the center of the bench and two 2x4s to go around the outside. Use the same method for the miter cuts to create the sleek border look before you screw the supports and legs on. It will actually be easier because you don't need to create the center brace. You'll just use 3 pairs of legs on each bench instead. This adds support for sitting on the bench that isn't needed on the table, which just needs the leg room (the reason for the brace underneath rather than an extra set of legs).
Step 6: Sand & Stain
Lastly you'll need to take a belt sander, or just straight up sandpaper if you're man enough, and sand down everything with some coarse 40-50 grit paper and then go back with some fine 120 grit paper. This worked well for me, even with my rough cedar wood. Once you wipe the dust clean with a damp cloth, get your stain or sealer and have at it. After you spray it down, spread the stain with a wide foam brush so it doesn't puddle up. A general purpose deck sealer will suffice. I chose to only sand down the top surface and edges of the table and benches and leave the rest with a rough, natural look.
