Glass - one of the most widespread building materials. It is rather inexpensive and is popular. Modern manufacture offers a wide choice of glass - both usual, and decorative. The simple technics of work with it does not demand a considerable quantity of tools, and those are simple in circulation. It gives the chance umeltsam to use the given material not only in the decorative purposes, but also for a glass cover of building designs: windows, doors and even roofs and facades.
The glass type, the size and place of its use in a building choose taking into account requirements of fire safety, zvuko - and thermal protections. The choice of a thickness of glass depends on the size of sheet, its necessary wind stability (in the solid firms trading in glass, always are tables on which it is easy to define a necessary thickness). Basically, for the household purposes use usual sheet glass in the thickness of 3-4 mm.
At observance of key rules to process glass it is simple enough. At work with it use gloves which should not be rigid that it was possible to "feel" a material.
Gauging and marking has flown down
For a glass cover basically the light and cleared sheet glass is used. Its edges seldom happen equal, strictly parallel and perpendicular that it is necessary to consider at a marking. Before to start to rezke, recheck gaugings. Do not assume in advance that a glazed frame — rectangular. Measure separately its each party, marking discrepancies between the opposite sides. Then subtract 4 mm from length and width. It will allow to consider roughnesses of glass and it is easy to establish it in a frame.
Preparation has flown down to processing
For glasses to you are sharp the big sheet DSP is required. At its absence it is possible to use the big table, on which it is necessary to lay a thin blanket to protect a surface from scratches. Before cutting of preparations of the difficult form it is necessary to make in advance templates of a dense cardboard, carefully having verified the sizes. The template should be hardly less, than a demanded profile. The allowance in 3 mm considers distance from edge stekloreza to a cutting edge of a castor.
The tool with tverdosplavnym a castor approaches for are sharp almost all types of glass and essentially is cheaper than the diamond. Still the metal ruler and a colour marker for a marking is required to you.
If it is necessary for you to work with a considerable quantity of sheets, we advise to get the T-square that will allow to cut glass precisely and exactly on all length.
How to cut glass
Preliminary wipe a surface a liquid for clearing of glasses or methyl spirit. Then note lines reza and once again check up the sizes. In advance grease the tool, having spent it on a slice of the felt moistened with lubricating oil. Hold steklorez so that the handle remained between index and average fingers, and the palm edge concerned glasses. Cut the confident, uniform movement, conducting a hand «on itself» that not sheet surfaces the visible line was drew. Do not do repeated are sharp, as glass can burst not there where it is necessary.
Slightly raise sheet and knock with a lateral part of the tool from below along a line reza. Enclose under glass a lath precisely on a line. Finger-tips (on either side of from a cut line) press downwards slowly, but it is firm until pull down it.
For removal of the remained ledges of glass it is possible to use pincers or flat-nose pliers with which help break off unnecessary parts. It is not recommended to use the cuts which are available on stekloreze for this purpose — they are intended for an estimation of a thickness of glass.
How to cut circles from glass
It is for this purpose necessary special steklorez. It consists of the cutting castor fixed on the handle regulated on length which rotates on the hinge attached to a sucker.
At first define the circle centre. It is easy for making carrying out of diagonals in a square limiting the area where there will be a circle. A marking spend a marker, then designate exact radius of a circle with the centre on crossing of diagonals.
Fix a sucker stekloreza in the circle centre, expose the handle for necessary length. Spend a circle, holding the tool firmly and slightly pressing. Then shift the handle on 20 mm inside and draw the second circle named circle of safety; it will protect edges of the necessary circle from having chopped off.
Metal tip of the tool tap from below along two circles. Operate slowly and carefully. The purpose of this work — to facilitate a splitting off of glass in circles. Having divided an internal circle into sectors, make sets of cuts which will facilitate removal of an internal part. Tap steklorezom in a circle and remove splinters.
Divide the area formed by two circles, into separate sectors with intervals of 25 mm. Having cut sector, do not cross a line of an external circle. Pincers accurately break off unnecessary edges.
How to drill glass or a mirror
More often happens it is necessary to drill an aperture through which it then fastens to a wall in a mirror.
For work the manual drill and tverdosplavnoe a drill is required. The electric tool which has been not equipped with a regulator of speed, for these purposes usually is not necessary, as speed should not exceed 350 rpm.
Put sheet on an equal surface. Note a drilling place small pressing of a tip of a drill glass or a mirror. It is necessary for making, that the drill has not withdrawn aside. If it is necessary to drill a mirror, it is necessary to begin with the nonreflecting party not to damage a silver dusting.
Moisten the end of a drill with turpentine and discipline a drill at right angle. Avoid strong pressure upon a surface. It is useful to make round a drilling place "pool" of plasticine or window putty where turpentine is added. Especially accurately drill on an exit: oslabte pressing, but do not stop rotation, differently glass or the mirror can crack round an aperture.
Processing of sharp edges of glass
After it is sharp also drilling are finished, sharp edges are necessary for smoothing by means of two abrasive karborundovyh stones - average and polishing. The pumice powder also is required to you. It is necessary to moisten abrasive stones and pumice in an operating time.
At the first stage dull sharp edges of glass. For this purpose use an average abrasive stone which is held at an angle by 45 degrees. Further, serially using a polishing stone and a pumice powder, lead up sides to the necessary cleanliness.
