often rails on the roof of the car is compared with the large all-wheel drive SUV, and even with rest and exciting journey.Although if you look at it more closely, it is not difficult to determine their actual, an extensive range of applications.But the rails are installed on the roof of the car, not just for aesthetics - they are very practical function.Judge for yourself - all thanks to several steel crossbars, you can easily carry any cargo, household goods, clothing, mountain bikes or stroller.Due to its versatility, this item is widely used not only on minivans and jeeps, but also in cars, both domestic and foreign production.However, the cost to them at times very high, which is why there is a need for their independent manufacturing.How to make the boxes on the roof of the car with their hands?The answer to this question will learn in the course of today's article.
What is the advantage of home-made railings?
The first is the cost.Buy rails on the roof of a vehicle type VAZ "Kalina" is possible by 4-4.5 thous. Rubles.The cost of home-made counterparts, and will not exceed one thousand rubles.Secondly, it is vernal view.If you own a full-size SUV, roof rack, made for industrial purposes, would clearly not decorate its appearance, and especially to give him aggressive.Agree, 1.5-centimeter cross obviously will look ridiculous appendage on a background of 4-5 meter wide jeep 2 meters or more.Third, it strength.Of course, the factory products also are designed for huge load, but a 60-120 kilogram here is unlikely to.And on these rails, as shown in the photo below, it is safe to transport even sheets of slate construction:
About manufacturing trunk
before application of the need to accurately determine its size.Dimensions railings must be clearly different from the width and length of the roof of a vehicle (at least their fastening places).As for the height parameter, it is not so important for the car, so you can take any value that is pleasing to you.After determining the size of cross tube should be cut into the desired length.The number of cross - from 2 to 4, wherein the leg is extended to 8 points (not to bend the roof).Starting with the best of the lower base.
Produce lower base
Before tell you about the intricacies of these works, we note that in the absence of experience with welding machines welding best practice on any other hardware.Learn the basic techniques of cooking metal is very simple - it will take no more than 1-2 hours at a time.
to work on the production of railings, we need a smooth surface.Ideally suited as a metal table or a few stands of metal.Wood discard immediately as temperature melting in a couple of thousands of degrees Celsius is not excluded that part of the sparks will burn or ignite the surface.After welding seams necessarily zashlifovyvayut.Also ensure that the joints were not burnouts - it will significantly reduce the strength of the structure.
Produce upper base
This part of the trunk should be done strictly according to the size of the lower base.Remember that even the slightest deviation will significantly distort its appearance.Further, by means of crosspieces connect the two halves of the parts.Here you can go two ways - to consolidate all tightly welded or leave the upper part removable to allow the use of design as a platform.
Next zashlifovyvayut remaining seams and begin to paint designs.If the boot drive will be used frequently, it can be built matched reflectors, duplicating the stop lamp or reversing light, but not necessarily.Of course, all of this technique requires additional holes and wires to connect to the on-board power supply.Colour design can be anything, but it is better to use either matte black or silver metallic.Previously should be smoothed cross from rust, degreased and primed (preferably 3 layers, as there will always rub a piece of metal).
How are roof racks car with his hands?
final stage - setting the structure on the vehicle body.Most of the difficulty here are fasteners that are often necessary to produce their own.For each attachment you want to use 2 bolts and nuts and the same tube diameter bolts.Remember that the trunk should not be harmful to the car, so the mandatory set in these places a special rubber gaskets.
How long will take this all work?
Many motorists believe that the process of self-construction and installation of a roof rack is very long and complicated.But in reality, it is enough to have no more than two days of free time.It is not necessary to be a professional design engineer and have expensive equipment for welding.
What benefits will we do?
In addition to the established makeshift roof rails allow the vehicle to safely transport large quantities of a variety of goods, it should be noted that these cross significantly alter the appearance of your vehicle.The presence of several steel crossbeams on top can become a final chord in transforming the design of the machine.Roof (especially chrome) look very stylish and elegant.In addition, this rack could become a highlight of the exterior and make the car more individual appearance.
So, we figured out how to make railings on the roof of the car with their hands, and what advantages gives us the existence of this design in the car.
