The technique of cutting glass is not very complicated, but it requires great accuracy and accuracy. Cut a rectangle of flat glass is much easier than making a hole.
Having the necessary tools, you can easily cope with this work.
You will need
- - Acetone or alcohol-
- - sand-
- - wooden stick-
- - tin or lead-
- - turpentine-
- - camphor-
- - Aluminum alum-
- - plasticine-
- - the cloth-
- - drill-
- - copper tube-
- - screw-
- - trihedral file-
- - cardboard-
- - Abrasive powder-
- - liquid glass-
Place on the glass where the hole will be, carefullyWash off dirt and grease with alcohol, acetone or gasoline. Pour on it fine wet sand. Take a sharp stick of the required diameter and make a funnel in the sand to the glass.
In the resulting form of sand pour molten tin or lead. After two minutes, sweep the sand off the glass and take out the cone of solder. You will get a smooth through hole.
Cut a hole in the glass is also possible withHelp carbide drill. Success depends on the liquid that will be wetted by the glass. Prepare a mixture of turpentine and camphor. Dissolve in it aluminum alum.
Degrease the glass. Put it on a soft cloth. It should lie completely on the surface so that the edges of the glass do not hang.
Make a roller of plasticine around the drilling site. Pour the prepared liquid into the improvised bath.
Take the drill and clamp the bit in the chuck. The rotation speed should be minimum. Turn on the drill and check that there is no drill of the drill during operation. When the beating is strong, the glass will crack.
Place the drill in the center of the hole you need. Make a hole. Do not press strongly on the drill, otherwise the glass may crack.
If you need to cut a large hole in the glass, then make a special drill. To do this, take a copper or aluminum tube with a length of 60 mm.
From one end into the tube, hammer a wooden plugTo a depth of 25 mm. In it, screw a 5 mm thick screw so that part of it protrudes by 15 mm. Saw out the head. At the other end, use a trihedral file to make dents.
On both sides to the glass glue cardboard washers,With holes of suitable diameter. Place the glass on the rubber surface. Place a little mixture of abrasive powder and liquid glass on the drilling site.
Insert the protruding end of the screw into the drill. Lubricate the teeth with turpentine and start drilling. When deepening the tube in the glass by a third of the thickness, turn it over and finish the drilling on the other side.
