1. Removing a bushing from a blind hole is not an easy task. You can solve it like this: pour thick engine oil into the hole, firmly insert a steel rod into the bushing and hit it with a hammer. The impact energy, transmitted through the oil, will knock out the bushing.
2. Spray head from used aerosol can, inserted into a rubber bulb, will turn it into an excellent atomizer for liquids.
3. A simple piece of equipment metal corner will greatly facilitate the manufacture of frames for paintings and photographs.
4. In the midst of home canning, a lot of dry, sterile jars are required. You can solve this problem like this: wash a lot of cans at once, put them in several rows in the oven gas stove, light a low fire and hold, jars at a temperature of 120 degrees for 5-10 minutes. There they dry and are reliably sterilized. Cool the jars slowly without removing from the oven.
5. Fake diamond can be used in construction in the form of bricks. Ingredients: magnesia - 35%, fine sawdust- 65%, 0.1 - magnesium chloride solution. Mix everything until a doughy state. Then pour into molds.
6. , it turns out that you can solder with the composition: lead - 25%, tin - 10%, bismuth - 40%, cadmium - 10%, mercury - 15%. This solder is also suitable for metals. This is how metal is soldered to glass.
7. The inscription on the glass is made with the following composition: liquid glass - 12 w / h; distilled water - 16 w/h; barium sulfate - 10 w/h; silicic acid - 1 w/h; mineral paint - to taste and tone. Silicic acid is not difficult to prepare; To liquid glass add an acid such as HCL or H2CO4. The resulting precipitate is silicic acid. It is washed, dried, crushed.
8. Do you have cracks in the old tiles? Want to try to hide them? cut out thick paper stencil with the desired pattern, stick it with rubber glue on a tile degreased with acetone. On open areas Apply car nitro enamel to the surface using a spray gun (you can use nitro paint in an aerosol package). Once dry, remove the stencil. The coating will turn out to be resistant to moisture, smooth and shiny.
9. The cover can be dyed. To do this, the floor must first be washed with a solution of laundry soda, then clean water and dry.
10. Nothing is more annoying after a repair than indelible dust from whitewashing and splashes of oil paint on a window pane. It should be borne in mind that:
Oil paint will not stick to glass if before painting window frames smear it with vinegar.
The glass will be protected from paint by paper strips 50 mm wide glued with soap along the window frame.
There will be less dust if before removing old whitewash cover the furniture with foil, cover the floor with newspapers, smear the ceiling with paste, let it dry and remove the whitewash with a scraper.
11. When painting walls in two colors along the border of colors, you can stretch and stick an insulating tape to the wall, which will allow you to get a smooth edge. Remove the tape after painting.
12. Screwdriver "lost" the handle - this happens quite often and is difficult to repair. But if you pour a little into the handle hole fine sand and crushed rosin, and red-hot the screwdriver before repair - the connection will turn out to be almost stronger than that provided by the manufacturer.
If, for some reason, the handle is completely lost, you can make a new one from a massive piece of plexiglass: clamp the screwdriver into the chuck of an electric drill and drill the plexiglass with it. The parts to be joined during the friction process will warm up, then cool down and “grab” very well.
13. Are the pliers opening too tight? This trouble is easy to deal with: you just need to drill a small hole in the center of the axis. If a small hole does not help, its diameter should be increased, just do not overdo it: you should not make a hole more than half the diameter of the axis.
14. Driving a wedge into the handle of a hammer or ax, drive it at an angle: it will wedge the handle in both planes and will hold on stronger.
15. The handle of the chisel will not split during operation if you put an ordinary beer cork on its end. And the mallet will last you much longer if you wrap it tightly with electrical tape.
16. Drilling, by the way, is also possible with the help of a drawing compass - wood, plastic, textolite. Just remove the needle from the compass and insert a small drill in its place.
17. Chewing gum - yes, not simple, but used - can be useful to a home master in many cases, sometimes unexpected. It is clear that screwing in hard-to-reach places will become easier if the screwdriver and screw are connected with such a mass; but the use of chewing gum as a sealant when connecting pipelines is a less obvious solution, but gives a good result. (And "Orbit" was once either "Dirol", with or without sugar - it doesn't matter at all.)
18. If you need to cut a narrow groove in the part (for example, a slot in the head of a screw), but there is no special one, such as slotting, a similar operation can be performed using a conventional hacksaw for metal, slightly modifying its blade. For this, on a rotating grinding wheel on both sides of the web, the side edges of the teeth are grinded evenly along the entire length until the “divorce” completely disappears. A properly ground-off fabric should have smooth, shiny surfaces on both sides and a thickness on the side of the notch, by 0.1-0.3 mm. larger than the non-working edge.
19. A convenient scriber can be made from a watch screwdriver, in which the working part is replaced by a piece of a thick sewing needle.
20. A sharpened copper bar scriber is convenient for marking ferrous metals.
21. The harder the material to be drilled, the greater the sharpening angle of the drill should be: for wood - 60, for metals - more than 90, for glass (and hard steels) - 120 degrees.
22. If thin drill is poorly fixed in the drill chuck, it is necessary to wind a tinned copper wire with a diameter of 0.4-0.6 mm around the drill shank. - tightly, coil to coil, in one layer, and solder.
23. The roller from the glass cutter is suitable for engraving on glass, metal, plastic, if it is fixed in the tip of the drill with an abrasive disc holder or mounted on the axis of any small motor. With sufficient motor power, the roller easily cuts glass to a greater depth.
24. A needle from a medical syringe will help restore the seam in hard to reach place. The needle is inserted into the opening of the seam from the outside, and an ordinary sewing needle from the inside is touched by touch against the bevel at the end of the medical needle. With a sewing needle, the needle is squeezed out from the syringe and the sewing needle and thread are easily pulled through.
25. In the absence of a micrometer, you can determine the diameter of the wire by winding several tens of turns of wire around a round rod or pencil and dividing the length of the winding (in millimeters) by the number of turns. With careful winding and sufficient length it is possible to measure the diameter of the wire in this way with an accuracy of 0.01 mm.
26. Knives, chisels and other cutting tool they are easier and faster to sharpen if you first lower the blade for half an hour in a weak solution of table salt, and lightly moisten the bar with kerosene.
27. Various (not too volatile) liquids consumed in small doses are conveniently kept on hand in small polyethylene bottles with a screw cap in which a small hole is drilled or pierced. Turning the bottle down with a cork and squeezing its walls, squeeze out the desired dose of liquid, for example, to degrease the surface, to wet an emery bar or swab, etc.
28. After two thermal shocks and drying, mica easily splits into plates up to 0.02 mm thick. To do this, the mineral must be heated to 400-600 C, immediately cooled in water and the operation repeated.
29. In the manufacture and repair of various equipment and tools, especially soldering irons, it is sometimes necessary to bend mica with a small bend radius. In order for mica to become more elastic, not to break or crumble, it must be calcined, heated to a light yellow color, and allowed to cool slowly.
30. Bonding dissimilar plastics, such as organic glass or polystyrene with celluloid, is difficult because dichloroethane, which is a solvent for organic glass, does not dissolve celluloid, and acetone does not dissolve organic glass. A mixture of acetone-based adhesive with dichloroethane-based adhesive does not provide high bonding strength.
The strength of the glued joint, equal to the strength of the materials being glued, can be obtained if the celluloid part is lubricated with acetone glue, and the part made of organic glass or polystyrene with dichloroethane. After the glue has dried, each part is smeared again with the appropriate glue and pressed one to the other. Final drying is carried out for 4-6 hours at room temperature.
31. Old rubber products can be restored to softness and elasticity by immersing them for 20-30 minutes. in a weak solution ammonia. You can immerse the rubber product for 1-2 hours in clean kerosene. At the same time, it should be remembered that a long stay of rubber in kerosene can not only soften it, but also significantly increase its volume. Softened rubber should be washed in warm water With detergent and wipe.

The back side of the hook is degreased with a solvent and also covered with two layers of glue with intermediate drying, after which a piece of cotton fabric is placed on it, glued, and then dried. In conclusion, both surfaces are covered with glue, allowed to dry for 5-10 minutes and tightly connected. A day later, a product weighing up to 10 kg can be hung on a hook. For this operation, it is best to use glues "Moment" and "Phoenix".

The procedure is continued until the required gap appears between the door and the floor.
Box-shaped milk cartons can serve as a ready-made mold for making concrete blocks. Size 65x65x240 mm.
Such blocks can be used as a curb stone, for decorative finishes and other purposes. To give greater strength, the blocks can be reinforced with pieces of wire.
To prevent decay wooden beams and pillars, they are pitched. This is done as follows: the end of the column is wrapped with 1-2 layers of roofing material, fixed with thin wire or small nails, and then heated blowtorch. The bituminous impregnation of the roofing material is melted, and it is tightly welded to the wood.
A narrow strip of paper folded in half will help protect your fingers when driving small nails. In addition, it can be used to hammer a nail when it is impossible to hold it with your hand or any tool, for example, in a narrow gap.
Driving a screw into hard wood is not easy. Poke a hole for the screw with an awl, and rub the screw liberally with soap. After that, wrapping the screw will not be difficult.

Banks will help to store things not only on the shelf, but also under it. IN glass jars very convenient to store nails, fasteners and other small parts. So that the jars do not “dangle under their feet”, they can be fixed above the head - just drill a couple of holes in the lid and screw it to the shelf with self-tapping screws. For storage, you just need to screw the jar into the lid. Good large lids usually cover jam jars.
Thanks to the hooks, the keys will not get lost in the drawer. Every house has drawer, full of rattling keys that are rarely used but cannot be thrown away. So that the keys do not rattle and do not roll under other things, they can be hung on hooks - right inside the box.
Dish drying will organize the tools. We spied this recipe on YouTube. It turns out that dish dryers seem to be specially designed for storage. wrenches. And they come in almost any size and shape and, if necessary, bend well. Therefore, dish drying can be selected for any garage drawer.
Magnetism vs Chaos
Determine the type of metal under the paint. .To drill steel, be sure to use drilling paste. In the case of aluminum, paste can be dispensed with. How to determine what kind of metal is hidden under a layer of paint? Winged metal is indifferent to magnets, while steel is attracted to them.
Don't lose small details. Small screws, nuts and washers tend to roll into places where you will never get them. It is easier to store them next to a magnet, which will easily subdue their ardor. By the way, with the help of a magnet, you can conveniently carry small fasteners in your pockets.
To pacify the butter dish dancing at the machine. The vibrations of the engine of a machine or tool can gradually and imperceptibly push off the table light oilers and spray cans that may need to be kept at hand. To prevent the containers from “dancing” on metal surfaces, attach a magnet with a soft rubber gasket to their bottom.
The trash bag saves water. To carry a bucket of water without losing a drop, a simple trick will help. Place a large trash bag in the bucket and pour the liquid directly into it. Then tie the bag in a knot and run home, boldly swinging the bucket.
The jack defeats rust. Dismantle outdoor unit air conditioner, rusted to the supports, a jack will help. It can be rested against a nearby wall, window sill, or directly into the ground if the unit is hung low. As a rule, it is enough to make only a couple of turns.
The bolt and nut fix the chain. A bolt and nut of a suitable diameter is quite capable of quickly and reliably repairing a broken chain. The main thing is not to forget to remove the broken ring before this: being open, it easily bends, turning into a real “weak link”.
Left is right, right is wrong
Adjustable wrench for dummies. This has amazing handy tool only one drawback - the ability to unexpectedly slip off the nut or bolt head. This happens due to misuse. There are two simple rules: first, pull the key, and do not push it - this way your hands will be safer. Secondly, the main force should fall on a fixed sponge - a movable one under heavy load can “release” the nut. So, hold the key with a movable sponge towards you and pull it towards you.
Water pipes not visible until they leak, says folk wisdom. To communicate with plumbers, use our concise illustrated dictionary.
Food coloring will indicate a malfunction in plumbing. Condensation or dew on pipes is often mistaken for a leak. If you have your own boiler in the house, then the diagnosis is very easy. Add food coloring to the boiler and see if your "dew" is colored.
The tennis ball will bring the blanket to life. Blankets and sleeping bags become less warm over time. This is due to the fact that the air cavities, which provide heat-insulating properties, are crushed and reduced. By placing the blanket in the dryer along with a couple of tennis balls, you will fluff it up well and refill it with air.
What is a staple? Not everyone office workers know the answer to this question. In the meantime, this report stapler is also great for storing hacksaw blades. This method will help protect your hands from cuts, and the blades from blunting.
Today we will tell you how to make five useful homemade tools for home.
Hi all! In this episode, I will show you some interesting ideas some of which you might like.
If you need to cut a plastic or metal pipe, then the following tool will help you. 
Take a measuring tape from a tape measure, cut off 40-50 cm, evenly folding the ends together, drill two holes and tighten with small screws. 
Now you can easily draw a line along which you will make a perfectly even cut. 
If in time in a hard-to-reach place, tormented by an open-end wrench, you lose a lot of time or patience, and you can’t get close with a ratchet, then perhaps you will need a screwdriver with a universal joint.
To do this, we need an adapter for heads from a screwdriver with interchangeable nozzles. 
With an emery or grinder, we grind the nozzle and a screwdriver on both sides, cut off about 2.5 centimeters from a suitable bolt. There are two holes on both ends, we make two cuts at 90 degrees relative to each other. We just have to drill holes in a screwdriver with an adapter and pin it. 
Now unscrewing the bolt or nut in difficult place, you will not lose liters of sweat for every millimeter passed with an open-end wrench)) 
Do you need to pour liquid into a container with a small neck? In this case, a small funnel can be made from the fuel filter. You just need to cut off the outlet part of the filter and the funnel is ready. 
You may have noticed inconvenience when changing a drill chuck, namely the slipping of the key teeth. You can upgrade it with a thick-bladed screwdriver. 
Having made a slot in the screwdriver shaft and sharpening the key shaft, insert it into the slot, and after drilling a hole, we tighten it with a screw. 
Now you don’t have to worry about the chuck’s teeth breaking off when you change drills in a hurry, and besides, now, thanks to the bright pen, it will be easier to find the key among the pile. 
If you need to draw a circle large diameter, A big compass you don’t, then you need to make holes on the carpenter’s square every centimeter. 
Now installing a drill or stud on zero mark, we can draw a circle of the diameter we need. 
And yet, after such refinement, it became easier to draw longitudinal lines. 
Perhaps the reader did not understand something, in which case you can watch the video.
