For performance of trihedral deepenings (fig. 101) take preparation of the necessary size. By means of a square spend on it an axial 1 continuous line. From them from two parties on distance of 2 mm spend a dotted line additional lines, that is define width of deepening.
101. Performance of trihedral deepenings :
And - trihedral deepening-flute; - a marking of deepenings; in - through deepenings; g-akrytoe deepening; d - a small square general view; 1 - an axial line; 2 - lateral lines; 3 - a platform; 4 - the face parties of deepening; 5 - a square from trihedral deepenings
The Cutting torch make an incision an axial line on depth of 3 mm or is a bit deeper. Then a cutting torch put on the right side from an axial line, that is to an additional line, give it the necessary bias, approximately 30-40° and with corresponding pressing conduct on itself, doing by that podrezku. Further preparation overturn on 180° also carry out same podrezku on the other hand. The cut off wood named straws, should depart freely after a cutting torch. If it does not depart, means, wood is not cut.
If to execute such two deepenings with distance between them, for example, 10 mm between deepenings there will be a platform. Having cut between these two deepenings two perpendicular deepenings, on the same distance from each other, we will receive a small square.
Such deepenings not always cut for all width or length of preparation on some millimetres then it is necessary to cut in addition and the face parties of a flute, or as though to cut the straws end.
In an operating time preparation krepjat to a workbench, a board or a table cover derzhavkami or thin carnations, driving in them from lateral faces. From face sheets they leave apertures which are not always desirable.
To Cut lines along fibres it is easier, than across. However thus the cutting torch tries not to go on year layers and deviates the spent lines aside, especially at krupnosloistoj wood, in particular at a pine and a fur-tree.
At prorezke lines across fibres it is necessary to press a cutting torch more strongly, but thus it goes strictly on the planned lines and does not deviate aside. It should be considered at performance of any carving, especially from pine wood.
Purer carving turns out, when the cutting torch goes in a direction of year layers from komlja to top. In this case the raising of fibres is possible, but they are smoothed by the tool, and the carving turns out pure and even with shine. At performance of a carving against fibres the last are often lifted up also cut places turn out rough and with a matte shade.
Small squares (fig. 102) are formed as a result of performance of the trihedral deepenings which had perpendicularly to each other. Small squares cut out in the following sequence. On preparation by a sharp pencil put lines up and down fibres through 10 mm from each other. Then from two parties of axial lines on distance of 1,5-2 mm spend a dotted line additional lines. Fix preparation so that at first to cut lines along fibres. When they will be cut out, preparation fix so that it was possible to conduct a carving across fibres. Technics of a carving same, as at performance of trihedral deepenings.
102. Performance of small squares :
And - small squares; - prorezka an axial line; in - the beginning podrezki a lateral line; g - the end podrezki a lateral line; d - podrezka the end (end face) of the cut two lines or straws
If small squares have turned out well, all the same operation is desirable for repeating that allows to seize carving technics better.
Having learnt to cut out small squares, perpendicular each other, it is recommended to execute them on a slanting grid, having axial lines at an angle 45°.
Drawing on a tape or flat carving looks not so accurately. To give to such carving sharpness, the shade which receive a wood cut external (fig. 103, and internal (fig. 103, 6), for example, at an angle 45° is necessary;. It is possible to cut off, lower the Keen edge of the cut off wood a little (fig. 103,) or to round off (fig. 103,). Cuts smooth carry out the direct cutting torches, rounded off - semicircular chisels. Having learnt to cut out trihedral deepenings, pass to a cutting of various triangles.
103. Relief registration :
And - with an external cut at an angle 45; - with an internal cut under the same corner; in - zatuplenie a facet with an internal cut; g - zakruglenie
By means of triangles of a various kind (fig. 104, and also almond-shaped deepenings, obrazuemyh curvilinear lines of identical size, ornaments create various on beauty and complexity.
For example, to an ornament of houses widely apply sockets of the square, rectangular, diamond-shaped, round and elliptic form. Carry out their various chisels, chisels, and also cutters.
The Technics of performance of ornaments from triangles consists in the following. On preparation put contours of drawing or all drawing and on the spent or planned lines start carving performance.
