How to make a compact folding picnic table

Make the seat and tabletop panels

Step 8. Make the seats and tabletop panels.

The size of the seats and table panels is crucial.
The panelA sheet that forms a distinct flat and rectangular section or component. A transparent panel used to fill a framed section of a window. sizes are as follows:
Shorter seat area, 190 (7 5/8″) x 880 (35 3/8″)
Longer seat area, 190 (7 5/8″) x 1010 (40 3/8″)
Tabletop area, 475 (19″) x 1090 (43 5/8″)

The formula – The most crucial measurement is the difference in length between the shorter and longer seat, which should be the sum of the thickness of four side framing members. For example, the side framing members are 32.5 mmAbbreviation for millimeter which is a metric unit of length equal to one thousandth of a meter. 25.4 mm equals one inch. (1 1/4″) thick. Four times that is 130 mm (5″), which is the difference between the length of the two seats.
This formula is worth considering if you want to make the seats longer, or use a thicker woodTimber, lumber. The hard fibrous lignified substance under the bark of trees for the side frames.

Below are the plans for the seats and tabletop. There are two options. The option used in fig.1, which is 140 mm (5 1/2) wide x 19 mm (3/4″) thick, tongue and grooveA joint in which a protrusion (tongue) that runs along the edge of a board fits into a matching groove that runs along the edge of another board. Boards shaped with a tongue on one edge and a groove on the other so that they can be fitted together without gaps. boards, and another option used in fig.2 i.e. using 90 mm (3 1/2″) wide x 19 mm (3/4″) thick boards.

Note: The sides of the tongue and groove boards fig.1 will need to be trimmed (ripped down) to achieve the correct width of the seats and tabletop.
