This is my first instructable! I have gotten many fine ideas from this site so now it's time for me to contribute.
Last summer I made one of these tables for our summer house. Our neighbours liked it very much so now I am going to make five more tables.
I build these tables from pressure- impregnated wood for long durability.
Step 1: Prepare the Parts
I went to the local lumber store and bought all parts needed. The cost for one table, including screws are about 75 EUR.
The planks for the table and bench parts measures 1700x120x28 mm (LxBxH). These are 12 pcs.
The planks for the sides/legs are all 120x45 mm (BxH) with the following lengths:
2x 1750 mm
2x 1000 mm
All angles cuts are 22,5°.
Additional parts needed are wood screws.
Step 2: Assembly of the Sides / Legs
Place the four planks on a flat surface. The top horizontal plank is placed with 50mm from the lower edges to the outside of each leg (see image).
The lower horizontal plank is centered.
The distance between the two horizontal planks are 200mm (or 320mm top-to-top.
Step 3: Putting It All Together
On one of the middle table planks, place two like-sided triangles (see image). This isn't required but simplifies the assembly. It also adds some stability.
Start the assembly by mounting the first table plank. Next, put one plank on each bench. Make sure the legs are leveled.
Finally, continue to mount all planks. Use a foldable inch rule to create some distance between the planks (see image). The smaller gap is for the table and the bigger for the benches.
Step 4: Finish Up
Finish up by sanding of the edges with som emery cloth (sand paper).
I also like to mark the table with my initials and the year built.
If the table is unstable, you can add two diagonal planks from each side underneath it. On my tables this wasn't necessary.
