1.1 Introduction
\n
The need for table comes only second to the need for seats in outdoor furniture. They will vary from permanent structures attached to the ground and of sufficient size for many people to enjoy meals, to smaller tables that can be moved to others, which may be folded and stowed away.
\n
Folding tables are described as one of the type of table. Within the other categories exist a vest number of designs; the primary need is a flat top at a suitable height from the floor. It is in the means of support that designs vary.
\n
Table tops for use indoors are always without gaps. If boards have to make-up a width, they are joined tightly edge-to-edge. Sometimes such a closed top is needed outdoors, but in many cases the top is made of many boards with gaps between. One advantage of this is in shedding rain water more easily, the gaps should no be too wide or there will be difficulty when a cloth is spread over and cutlery and other small items process the cloth into gaps.
\n
For normal use, the gaps should not exceed ½ inch (although there are many tables in use with wider spaces). A table should stand firmly, the ideal arrangement for stability is three legs that will not wobble, no matter how uneven the ground. For most tables, it is preferable to have four legs to give support near each corner.
\n
The spread of legs on the floor is greater than the spread of most chair legs. This aids in finding a level stand if the support is not individual legs, but there are broad surfaces at the bottom. It is always advisable to thicken at the corners to provide feet (As in the first example).
\n
Be careful to brace against diagonal or sideways loads, as well as those pressing directly downward. There must be enough stiffness in the joints. If the top and any shelf arte firmly attached, they also serve as stiffness, but if it is a table where someone will be sitting on a chair with their legs underneath, the rails have to be kept out of their way.
\n
The end rails support a shelf of slats for enough in so as not to interferes with a sitter legs at the side. Chairs are often made to match tables. Using generally similar layouts and construction, so there is a balanced appearance when several chairs are grouped around a table. Some seats for more than one person can be made to match as well.
\n
Assess your probable needs and keep in mind a general pattern, even if you are only making one chair at first. If chair are made from prepared wood, stock size of sections can be less than specified, because the quoted size is before us machine planed. For example, you will find that 2x3 inches quoted is actually not much more than 1 ¾ inches finished.
\n
Allow for it during making out, mark form the actual pieces of wood, rather than rely on measurements for widths of cuts. To obtain a better quality chairs and table galvanized nails are preferable which had good resistance to corrosion attack. Iron screw should also be protected effectively.
\n
Finally, wood also has good mechanical properties, thermal properties, electrical properties, Acoustical properties and high density and specific gravity which contribute primarily to high durability and workability characteristics during and after constructional operation.
