Carpenters look at the point, while bricklayers look at the edge.
The "tip" is the angle. The lofting and production of shelves, the installation of planers according to the cutting angle, the production of chisels, the filing of sawtooth, and the production of furniture tenons have various angles. Tip also refers to the operation quality of shoulder cutting and flat-fell seam in woodworking tenon combination operation, which is used to measure the technical level of woodworking. The quality of tenon joint is not only high or low, but also reflects the carpenter's knowledge and operation level in sample turning, drawing, material selection, line drawing and processing. It can be seen that these corners are the key to woodworking skills.
Similar to the proverb: carpenters dare not touch, masons dare not look.
Long carpenter, short blacksmith, neither long nor short stonemason.
Explain the characteristics of different industries and processing objects. It also explains the ingredients of carpentry and some working procedures (such as the length of tenon, cupboard door and drawer, etc.). ) there must be a certain margin, rather long than short, rather big than small.
A similar proverb: Carpenters are not afraid of long, and blacksmiths are not afraid of short.
One material, two wires and three holes.
The standard to measure the basic skills of carpenters. It depends on the plane to be smooth and square, the line drawing to be accurate, and the tenoning machine to be square.
Wood bent by a crooked carpenter can become useful after the carpenter bends it and keeps it straight. Woodworking needs reasonable selection of materials, clever use of inferior materials and improvement of wood utilization rate.
Carpenter's axe, mason's knife, bachelor's luggage, big girl's waist. These are not easy to touch, and the tools used to describe craftsmen are not lent to others casually.
Carpenter's axe, carpenter's saw.
Traditional carpentry is generally divided into three categories: rough carpentry for building houses, also called big carpenters, joinery for making furniture, also called small carpenters, carpenters for making pots with hoops, and also called round carpenters.
It is about the basic skills of different kinds of carpenters. Big carpenters need to saw logs flat, and the skill of axe and axe handle is the most important. Whether the tenons and mortises of doors, windows and furniture in Joinery Work are correct not only affects the appearance, but also affects the service life and quality of the interior. The level of joinery is evaluated by the quality of shoulder cutting and flat-fell seam in ordinary tenon joint. Saw is very important in many operations, such as planing, chiseling, sawing and cutting.
Little carpenter's material, big carpenter's line
Planing material is the most important basic skill for a carpenter. The carpenter drew lines from two huge materials. Only when the materials on these two sides are cut qualified can the lines be drawn accurately. Accurate alignment can ensure the subsequent machining accuracy. Planer should be straight, square and flat. Look at the other end of the material with one eye. If it is a straight line, it is straight, and the moment of inspection is square. When it is regarded as a plane, it will be measured with a ruler, which is consistent with the ruler. In this way, the material is considered qualified.
Great carpenters take thread as the standard. There is a center line, a horizontal line, dimension line. Beams, purlins, rafters, etc. , you must first pop up the center line, including the head-on cross center line and the straight center line, and then operate according to the center line. Construction lofting, big wooden component line, but also pop up the horizontal line and other dimension line. The big wood project with these lines is beneficial to construction. Therefore, the production line is the key link of large-scale wood processing and construction.
Study art for three years and make up art in March. When you become an artist depends on your craft.
Woodworking cutting formula II Woodworking cutting formula
Wood is born of trees, and the key is whether it can be used. Have practical production experience and precise production process requirements; Three-point blanking and seven-point work, wood knowledge is in mind. The quality of the material depends on the environment, and the material is divided into soft and hard. Master the theory, learn more, and observe and apply it in practice.
In order to do a good job in carpentry and better blanking, we must fully understand the materials, study more, practice more and observe more. The specific method is as follows.
1, learn more. Is to learn the relevant theories of wood knowledge. Such as the classification knowledge of wood; Structural characteristics of wood; Attributes related to wood and woodworking carving; Wood identification and defect correction, etc.
2. Practice more. That is, when learning woodworking carving technology, we should not only master the structural methods and skills of processed parts or handicrafts, but also use the knowledge of wood repeatedly in practice to select and match materials reasonably, so that the finished products can perform well in workmanship and make good use of high-quality materials.
3. Observe more. In practice, compare and observe the advantages and disadvantages of various wood materials; The forward and backward directions of wood grain were compared and observed. Compare and observe the wood thickness of wood; Compare and observe the color of wood; Comparative observation of wood grain morphology; Compare and observe the weight of wood. Only in this way can we learn to combine and improve woodworking carving technology.
