There is no limit to perfection. This saying is well known to one and all. And any car owner strives to make his car perfect. For many drivers, the factory settings are not enough. They strive to bring something of their own. Something that will set them apart from the rest. But what to do if what you want cannot be purchased in the store? There is only one way out: if you can’t buy it, do it yourself.

They have become very popular lately. They improve appearance cars, some change technical specifications or bring pleasant additions to the options. Among the variety of possible alterations, we suggest considering several options.

Car wash

Let's start with the appearance. When a car is clean, its paintwork shines and shines. It's nice to look at this technique. You immediately get the feeling that the owner is taking care of his car. But going to the car wash is not always possible due to various circumstances. In such cases, homemade car products will come to the rescue. You can assemble a small sink with your own hands, which you can use at any convenient time.

To make a sink you will need the following parts:

• canister with two drains;
• hose 2 m long (suitable for connecting a washing machine);
• watering gun with telescopic rod;
• union;
• spool;
• rubber gasket (outer diameter 2.4 cm, inner diameter 1.5 cm);
• coupling.

Now let's get started:

1. We make a hole in the lid of the canister. We coat the “spool” with sealant and insert it into the prepared hole in the lid. Let it dry.
2. We make a small hole in the second lid. It is necessary for treating the connection between the cover and the coupling with sealant and also allowing it to dry.
3. We cut off the nut with fastening from the curved end of the inlet hose. No need for fastening anymore. Apply sealant to the nut and secure it with reverse side couplings. We connect the cut side of the hose to the nut of the quick-release fitting. Next, the main fitting is screwed in, which is also connected to the watering gun.
4. On the second side of the hose, insert a rubber gasket into the nut. This will protect the system from air penetration. After this, the nut is screwed onto the quick-release fitting.

This completes the process of making a homemade car for a car with your own hands.

Seat reupholstery

Homemade products can also be useful for updating the interior. Useful gadgets and crafts for cars allow you to replace worn out parts, add lighting to the interior and do much more. Let's consider the option of updating the seats.

For this you will need fabric. You can choose two colors - beige leather will be suitable for the central part of the seats, the back of the backrest (about 4 m of it will be needed), and everything else will be black. Black leather needs about 3.5 m. All fabric needs to be duplicated (glued) with a layer of foam rubber 0.5 cm. The foam rubber is glued with non-woven material using an iron. This will make it easier to work with.

Co removed seats(it’s more convenient) remove the covers. We number their individual parts. In order not to get confused, we transfer everything to paper. Also on paper you need to mark the places where the knitting needles are attached (they are on the back of the covers). The knitting needles themselves will then be inserted into new cases.

Next, we disassemble the casing into individual parts (unravel the seams). Patterns of the necessary elements are obtained. We lay them out on the wrong side of the fabric (wrong side up to avoid mirroring the details) on thick paper (you can use wallpaper) and trace them around the perimeter. We leave a 1 cm allowance along the edges, which will be used for seams. Then all the patterns are cut and sewn (starting from the center). On the reverse side of any fabric we make pockets into which the knitting needles are inserted.

Having connected all the parts, we get new covers. We carry out this process one by one for all seats. Having made such interesting and useful homemade products for your car with your own hands, you can update the interior without contacting a service center.

Ceiling renovation

You can also replace the ceiling trim yourself. In this case, homemade products for a car must begin by removing the ceiling. This can take quite a long time. Fastening is individual in each case. There is nothing complicated, the main thing is to carefully inspect everything and check that all the parts remain intact.

When the ceiling panel is removed, the old fabric is removed from it. When preparing material for the ceiling, you need to remember one important point: on the wrong side it should have a small layer of foam rubber. The fabric is glued with heat-resistant glue. When the glue has dried, the panel can be reinstalled on the ceiling. Do this in reverse order.

"Angel Eyes"

It is quite possible to assemble useful electronic homemade products for cars with your own hands. For example, “angel eyes” will allow you to update the headlights of any car. To make them you will need:

• plastic transparent sticks (can be from blinds);
• resistors (220 Ohm);
• battery (9 V);
• LEDs (3.5 V).

The process looks like this:

1. On any metal can, the same diameter as the headlights, we screw a ring from a plastic stick using pliers. To do this, it is heated a little.
2. Next, connect a pair of LED and resistor. Their performance is checked using a battery.
3. Another LED is connected to it.
4. We make deep cuts on the frozen ring from a plastic stick.
5. We assemble the ring, attach the LEDs, and connect.

Conclusion

Subwoofer box filler

What filler to choose for the subwoofer housing.

When creating a subwoofer with your own hands, you should also consider what filler to choose for the box, and also take into account such rules as:

1) The material of the box should be as solid as possible. (knock on 8K plywood and then on 20K plywood and you will understand what I mean)

2) The box must be as strong as possible. (joints and connections must be stronger than the material itself)

Various homemade products for cars have always been of interest to motorists. They are all designed to improve performance, appearance or comfort. passenger car. For example, you can make a subwoofer, a convenient organizer, eyelashes for headlights, license plate protection, etc. with your own hands. We will tell you about some useful homemade products that are available to everyone.

Every motorist strives to make his car unique. This can be done with the help of unique overlays on the headlights, which are called cilia and add some zest to the appearance of any car.

To make your own eyelashes you will need the following:

• construction hair dryer;
• thick paper or cardboard;
• primer and paint;
• sandpaper;
• hacksaw;
• scotch;
• plexiglass.

First you need to decide what shape of eyelashes you want to get. The choice depends on your preferences and imagination. Draw a template on paper or cardboard and cut it out. You can use it to cut a piece of plexiglass in the future.

Attach the created template to the headlight of your car and give it a finished look by carefully adjusting all the edges. When everything is ready, attach the template to the plexiglass and trace it with some sharp object. The part should be cut out along the resulting contour.

In order not to damage the headlights and protect them from scattering, it is better to cover their surface with tape. Use a hairdryer to heat the workpiece, and when it begins to bend, you can apply it to the headlight.

After this, the surface must be treated with sandpaper, moistening it with water. When everything is dry, prime the part and then paint it in any suitable color. Everything is very easy, and the result can exceed all your expectations.

If on rims If your car has scratches or chips that spoil the appearance of the product, you can take the wheels to a specialized workshop for painting. If you don’t want to spend money on this, you can try to restore the damaged areas yourself.

To work you will need:

1. Scratched discs.
2. Epoxy glue of any color, since a layer of paint will be applied on top. However, if the paste is too bright, it may show through the paintwork, so before applying paint it is better to prime everything thoroughly with a primer.
3. Sandpaper number 300-400 and 600.
4. Adhesive tape.
5. Spray paint and varnish.

First, using coarse sandpaper, you need to clean the places of chips and scratches to such an extent that you could not feel any bumps with your hand. We recommend covering the rubber with adhesive tape and covering it with newspapers to prevent paint from getting on it.

Mix both components of epoxy glue in a one to one ratio. Apply the mixture to the cleaned scratches so that the mixture completely fills them, and a thin layer forms on top.

Dry everything thoroughly. This takes a lot of time, and to speed up the process you can use heat by placing a fan heater or a simple incandescent light bulb near the disks.

When the glue has dried, sand it with fine sandpaper, preparing the surface for painting. Everything should be smooth to the touch and look - this is important.

Using a spray can, painting the rims is not difficult at all. You need to thoroughly shake the can and start spraying the paint from a distance of 20-30 cm. The paint should be applied in layers. Avoid too obvious transitions by applying two or three layers. Each of them needs to be dried, waiting for half an hour. To protect fresh paint from dust, it is better to carry out painting work in a pre-humidified room.

After the paint has dried, apply two coats of varnish. Between layers you need to wait half an hour, and the top layer should dry longer.

When everything is thoroughly dry, you need to moisten the finest sanding paper (1000-2000 grit) with water and carefully smooth the varnished area. To achieve factory shine, the surface can be polished.

The theft of registration plates today has become one of the illegal ways for criminals to earn money. It takes thieves no more than 10 seconds to steal license plates from a car.
