Tools and stock (ch. 2)

Manual saws happen two-manual, nozhevye (nozhovki) and luchkovye.

Cross-section two-manual saws serve for a cross-section cutting of round wood, bars, thick boards. Length of saws 1000, 1250, 1500 and 1750, and width of 140 and 160 mm. The thickness of a cloth can be 1,1 and 1,4 mm. Teeths have the form of an isosceles triangle. Sharpening of teeths - slanting. Nozhovki happen wide, narrow and with obushkom. Wide it is used for a cutting of boards, bars and other details. Its general length of 533 mm, length of a cutting part 450, width of a cloth at the free end - 40, a thickness of a cloth-1,2 of mm. Narrow nozhovka it is applied to curvilinear sawing up, and also for through propilov. Its length usually 460, width on the free end 20 ^-40, a thickness of a cloth - of 1,5 mm. Nozhovka with obushkom it is used for superficial propilov. The top part of a cloth has a thickening. Length of a saw 300, width of a cloth 100, its thickness of 0,8 mm.

Exists still nozhovka-nagradka for not through propilivanija. Length of a cloth of such saw only 100-120 mm, a thickness of 0,6-0,7 mm. Luchkovye saws apply to a longitudinal and cross-section cutting of wood: raspashnye - for longitudinal sawing up with width of a cloth 45 55 mm, cross-section - with a width 20-25 and vykruzhnye - for figured (curvilinear sawings up) with width of a cloth 4-15 mm.

That not zaedalo in a prosaw, its teeths it is necessary to plant a saw. This process consists that tops of teeths serially (every which way) unbend from the basis approximately on 2/3 heights. Plant teeths with the special tool - distributing. Sharpen saws files trihedral, rhombic, round and flat (fig. 4).

Power saw Application considerably raises labour productivity. For mechanised pilenija more often, apply disk power saws with diameter of a disk.

saw Sharpening by a flat file of 160 or 200 mm. Saws do small depth has spent on drink - 45-70 mm. Fix saws on a table or a workbench.

Variety of various special tools is applied To wood planing. However are most necessary sherhebel, a plane and fuganok.

For the most rough strozhki if it is necessary to remove wood thicker 3 mm, serves sherhebel. They can plane up and down fibres, and also at an angle to them. After processing the wood surface turns out rough, with deepening traces. It speaks that an edge of its knife of the oval form with radius 35 mm.

Then the surface is necessary for processing an unary plane. For purer planing, and the double plane is intended for processing of the long surfaces demanding the big accuracy, - fuganok.

For sample of quarters, folds and zachistki them serves zenzubel. It has the lateral aperture providing a free exit of a shaving in the course of planing in the case. Knifes at zenzubelja under the form remind a shovel.

Shpuntubel is used for sample of grooves-shpuntov on edges and a surface of details.

Kalevkoj make profile processing of details. The sole of this tool has the mirror (return) form of a profile of a detail. For processing of different profiles usually there is a set kalevok.

To sample of nests, grooves, thorns apply chisels - plotnichnye and joiner's. Plotnichnye have length 345, width 16, 20 and 25 mm, and joiner's - length 315, 335, 350 mm, width 6, 8, 10, 12, 16 and 20 mm. Handles of chisels produce from wood of firm deciduous breeds - a maple, a beech, a hornbeam, etc.

The Edge of chisels has unilateral sharpening.

Chisels are used for removal of edges, zachistki nests, grooves, etc. They have length 240, 250 and 265 mm, width 4, 6, 8, 10, 12, 16 and 20 mm.

For drilling of apertures use rotations, buravy, gimlets, and also various kinds of drills - perovye, tsentrovye, screw, spiral. Perovymi drills choose apertures of different depth, tsentrovymi - through and superficial. Drills with a screw part apply to drilling of deep apertures. Spiral drills are most convenient for work - with their help pure apertures turn out. For work with drills use rotations, drills and vorotki.

The Electrodrill at work with a tree does not recommend to use, as in a soft tree displacement and ushirenija apertures are possible.

For glass works as the basic tool serves steklorez. In the thickness of 1-4 mm cut thin sheet glass roller steklorezom which usually has three cutting rollers, built in in brass barabanchik more often. Slightly having weakened the screw barabanchika, it is possible to turn and establish into position any cutting roller.

One roller without a repoint it is possible to cut not less than 350 m of glass.

Glass in the thickness to 10 mm cut diamond steklorezom, having cuts of different width with which help break glasses. Diamond insert into a frame so that it had two corners - stupid and sharp. The acute angle at rezke glasses should move forward.

For definition of position of diamond in a frame on the handle the label - an asterisk, a hyphen, etc. is usually put., which specifies in an acute angle.

Except stekloreza for glass works will be necessary a ruler with equal edges and divisions, kusachki and pincers For otkusyvanija nails and a wire, vytaskivanija hairpins, etc., and also a chisel which clear away folds from old putty, hammer in hairpins, etc.
