the Cutting of triangles with deepening of the centre and reception from them various friezes (fig. 104, 6). A triangle preliminary divide into three triangles, spend straight lines from triangle corners to its centre. Smaller triangles carry out separately with deepening of their tops therefore receive one triangle deepened in the centre.

The Frieze (104, consists of a number of the taken out triangles with deepening in the centre, located the bases on one straight line. Thus, each big triangle divide into three small, spend lines from corners to the centre. At first carry out small triangles, and then take out wood from the core (big) a triangle. Work carry out a direct cutter with an oblique edge, since incision of two lines of a triangle from the top which are subject to the greatest deepening. Thus a cutter acute angle put in top, and an edge it direct along one of the triangle parties. The triangle party make an incision before crossing with other party.

 

The Frieze (104, consists of the two first triangles represented in drawing 104, and and connected by the bases. As a result of cutting of wood at two triangles adjoining by the bases receive konusnyj a crest in the form of an arrow located along a frieze.

The Frieze (104, consists of two triangles (fig. 104, and,), connected by tops with two straight lines and one curvilinear the parties of Top of taken out triangles should coincide, have identical uglublennost, and also an inclination of surfaces of deepening.

The Frieze (104, consists of the rhombuses located on its middle. Divide rhombuses into two triangles, each of them take out with deepening in the centre. A frieze receive with vertically located crests-arrows.

The Frieze (104, carry out according to drawing.

A cutting treuglnikov a different kind: and - kinds of triangles; - the details of a frieze formed by triangles with deepening in the centre: 1 - top; 2 - the centre; 3 - the basis; in - the details formed by a combination of triangles with two primymi and one kriaolinejnoj by parties; g - the details formed by a combination of triangles from one straight line and two curvilinear parties; d - the details formed by a combination of triangles with three curvilinear parties; in - the details formed by narrow triangles with stronami of different length; - the details formed by almond-shaped deepenings; z - sockets from triangles

And - kinds of triangles; - the details of a frieze formed by triangles with deepening in the centre: 1 - top; 2 - the centre; 3 - the basis; in - the details formed by a combination of triangles with two primymi and one kriaolinejnoj by parties; g - the details formed by a combination of triangles from one straight line and two curvilinear parties; d - the details formed by a combination of triangles with three curvilinear parties; in - the details formed by narrow triangles with stronami of different length; - the details formed by almond-shaped deepenings; z - sockets from triangles

The Frieze (104, consists of a number of the asterisks entered in squares, each of which shares the diagonals on four triangles with deepening in the centre. Between asterisks vertical crests-arrows are formed.

the Triangles limited to two straight lines and one curvilinear party, and reception from them details (fig. 104,

In these triangles the curvilinear party can be convex and bent, cut out these triangles with deepening in the centre. Do cuts of a point of intersection of lines and form three small triangles. A cutting torch, or kosjachok, the sock put in a point of intersection of triangles. Wood cut at first on the direct parties, then - on curvilinear. The curvilinear parties of a triangle carry out a direct cutter with an oblique edge or a knife-kosjachkom. In narrow triangles wood can be cut out an angular cutter.

the Triangles limited to one straight line and two curvilinear parties, and reception from them details (fig. 104.

The Curvilinear parties of these triangles also can be bent and convex. Irrespective of an arrangement of the parties wood in them take out with deepening in the centre. At first at triangles make an incision internal lines of triangles as it has been described above, then cut the curve parties, take out wood and smooth out the received product.

the Triangles limited to three curvilinear parties, and reception from them details (fig. 104.

The Parties of such triangles can have the convex or concave form. Their carving is not enough, than differs from a carving of the triangles limited to two curvilinear parties and one straight line. At first make an incision internal lines, and then those parties which lie against acute angles. Cutting torches apply depending on krupnosti drawing, depth of a cutting and other data. Use an angular cutter and a knife-kosjachok is more often.

Narrow triangles with an entering corner and different length of the parties, reception from them details (fig. 104. The parties of triangles can be rectilinear and curvilinear. Triangles of this kind especially widely apply at performance of a geometrical carving. At corresponding configuration of triangles receive beautiful carved details. Carry out basically angular cutters, and cuts - direct cutters with oblique cloths.

Almond-shaped deepenings and reception from them details (fig. 104. These deepenings are represented by two crossed curvilinear lines or arches of identical curvature with the taken out wood. Distinguish mindaliny with full dredging of wood or with partial when in the middle mindaliny there is a diamond-shaped or figured ledge. In this case wood do not cut off, and it acts at level with a preparation plane. Partial dredging of wood represents as though a triangle with an entering corner.

Full almond-shaped deepening carry out a direct cutter with an oblique edge or a knife-kosjachkom, and also special cutting knifes with the bent cloth. A cutter sock put on one of planimetric lines of almond-shaped deepening so that its end has coincided with a point of intersection of arches. Pressing a cutter, slowly conduct it on a curve or on an arch, without deviating aside. A line conduct up to the end mindaliny, and then a cutter take out.

Having cut the first arch, preparation povertyvajut on 180° and in the same way cut the second arch. Thus, receive almond-shaped deepening with an acute-angled flute in the middle.

If in mindaline there is a ledge around do cuts, and then - almond-shaped deepening. At performance in mindaline other figured ledge increase quantity of cuts and instead of the simple tool apply the figured. In drawing 104, z sockets are shown: round, square and diamond-shaped.
