You should draw the outline on the wood with their realdimensions. To do this we use the pencil (hardness 2H or 3H) ora steel tip (nail), a linear rule (folding rule), a square rule for straight angles, a false rule for obtuse and acute angles and compass for curves…. If we draw parallel lines use the gage. Remember that to draw circles whose dimensions exceed the maximum aperture of a compass; you can use a nail, some thread and a pencil. If we have to draw a certain number ofidentical silhouettes (corners, edges …) we do prove morecomfortable using templates (eg hardboard).
Holding, supporting or holding the work piece during work
The essential clamping element is a workbench. It must beconstructed so that does not protrude from the nothing that could dent the metal tool, other accessories are not fixed.
Stood in natural attitude, wrist pointe us the right height of the bank, and elbow correspond to the height at which the metallictwang of fixing parts should be. The board or panel forming thesurface is usually ash, elm, beech or poplar. The legs and beamsare made of oak and very robust. The feet are connected together by four cross-pieces, with mortise and tenon assembly.
Sawing or cutting wood
The operation of splitting wood, divide and sawing is one ofthose that require more skill. We will have the wood stronglyattached to the workbench. The most important part of the sawblade is made of hardened steel, which in one of its edges has a number of more or less tight little teeth and inclined. The teeth are triangular in shape and are aligned as small chisels. However, they are inclined to the blade alternately left and right(side-set) to reduce friction and best sliding without heating by wood, making a wide enough to easily move around her slit.
Standards practices to keep in mind when sawing are when you start cutting you should support the left hand (assuming you are right-handed) over the end of the wood and lift thethumb so that it touch with the saw while it is aligned with the path (thus ensuring that the cut is made in the proper position).
Safety standards or to take precautions in the use of saws are basically warning chip that is produced from the cut (eye care) and always use the right tool for the type of work you want to perform, taking into account the materialand effort to implement, is not the same sawing thick logs table that a multi-ply plywood.
If the parts we have cut do not have flat and smooth surfaces, we will need hand brush. There are different types: There are those who have the wooden body and other parts of steel, and others that are completely metal. The classic brush consists of a block of hard wood with a hole in the port call center, where thesteel cutting blade held by a backiron that prevents vibrate and helps remove chips, and both are blocked by a wedge.Depending on the inclination of the blade chips are more or lessthick.
The blade must protrude from the mouth of the port one or two tenths of a millimeter when it comes to hardwoods, and two or three when the woods brushed is soft.
Sharpen / Scrape
When you need rough wood surfaces and prepare it forstraightening as well as reduce rounded points, concave orconvex, chamfered corners and jagged edges and chipped (alsoto remove scratches that may have occurred during the cut with the saw), use of the rasp is made.
With limes is obtained a more complete and perfect smoothing.The abrasive surface of the limes is like the skin of a fish, even though they are made with the same principle as rasps, the abrasive part is obtained with two series of ribs crossed forming a variable number of teeth.
The final finish has to be done with sandpaper. It is performed in separate parts before assembly or installation to finish, depending on the operations to be carried out to perform. Anyway, it is always advisable to sand the edges of the piecesseparately before assembly. Then, after finishing the work, the rest of the surfaces sanded.
Sandpaper is a very sturdy blade that has a few tiny fragmentsof glass glued on one side; its effect is similar to the teeth of a lime. Also grain sandpaper can have different thicknesses, from the most coarse to those who are very thin.
If you want after sanding polish the surface, the blade is used.Its blade is thin and sharp (steel), with cutting edge, which leaves the surface of the piece fully polished after the moment several times in the direction of the fibers. Polishing is carried out whenthe object has reached its maximum stability (after assembly and drying of the glue) by a crankpin. This is made with a cotton pad or tow wrapped in two pieces of thread to remove any loosehairs or tufts. The interior cloth is thicker frame while theoutside is finer.
Paint or stain
The paintings are treated liquid substances, surface application, usually colored, forming a layer or film on the part that applies. These substances consist of a solid pigment, finely powdered, which is soluble in the binder or liquid carrier, whose mission is to provide consistency and facilitate drying of the paint, forming a mixture can be matte or glossy as needed and features which is liable coated wood.
We consider painting as the last treatment made to a piece, therefore, must exercise extreme care and precautionsfor the perfect finish.
Varnishes are, more or less thick liquid, which extend over woodfor a clear, colorless, glossy surface or matte tone, as the varnish. For a varnish acted properly on the wood must dry quickly, give a permanent brilliance, join the woodysurface well, not fade for a long time and not lose flexibility, but the surface is exposed to the weather. Varnishesconsist of resins, gums or waxes, drying oils or dissolved in volatile solvents and dyes when they correspond.
