Materials and tools for manufacturing
A quality backhoe can be made in the garage without the use of serious equipment and with minimal material costs. If all necessary elements are available, the fabrication process takes about 1 hour.
Basic tools and materials for making a reverse hammer:
- Steel rod 12 mm in length of about 50 cm;
- Duct tape, duct tape;
- Steel rod 16 mm;
- Two large steel washers with nuts;
- Threading tool;
- Electric welding;
- Vise for clamping.
Inverse hammer design
There are several variants of the reverse hammer structure:
- Vacuum;
- with a pneumatic pulling mechanism;
- devices with several weights;
- models with an adhesive backing or interchangeable attachments.
The first of the presented types has a unique advantage over similar devices. Vacuum suction cup allows you to make repairs without damaging the paint coating. Depending on the power of the vacuum backhammer, it is possible to pull small and medium-sized damages on different parts of the body. However, a special technique must be followed: pulling from the edge of the damage to the center of the damage. Otherwise dangerous tension is created in the metal, which can lead to fracture or unpredictable deformation.
Pneumatic backhammers are convenient because they require reduced force to perform the work. Also an area where this tool is indispensable is under the hood, including the removal of stuck parts.
Homemade reverse hammer can be constructed from the simplest components:
- A metal rod of suitable thickness and length of about half a meter;
- steel washers of appropriate diameter to install the stops;
- Weights to increase the force;
- Rubber handle (can be replaced with any other convenient material);
- A hook or metal plate with a holder. depending on the design of the intended hammer.
It depends on the condition of all components whether grinding and cleaning of metal parts will be necessary. For this you can use sandpaper or a disc for grinding metal, and also special compounds can be useful. It will depend on the design features whether a welding machine will be needed or only a threading device will be required. Most often, however, you can’t do without welding, because it’s better to fix the lock washers to the hammerback rod with a secure weld.
Disassembly of the shock absorber strut
In order to be able to make a useful thing from the rack you need to disassemble it properly. A VAZ stand is best suited for this purpose. The upper part and the rod itself will come in handy.
Clamp the rack in a locksmith’s vise, with an angle grinder you need to carefully saw off a part of the tube to the plate, where the spring stands. Saw carefully, remembering that there is oil inside! That’s why it’s better to set up a dishtowel. It is necessary to remove all elements from the rack, disassemble and leave one rod and the top cover (taking out the gland and bushing).
Self-made
To make a reverse hammer at home with their own hands is simple enough. It does not take much time, and does not require special materials and tools. For a better understanding, you can watch a video on the internet. The primitive drawing also will not be superfluous.
To make this tool with your own hands will need the following:
- metal pin about 50 cm and 20 mm in diameter;
- Load, which has an inner hole;
- Threading tool (optional);
- welding machine;
- angle grinder.
If it is decided to make a backhammer with a hook-type attachment, a hook is made at the end of the pin. It can be done with a vise or pliers. Or use a welder to weld on a ready-made hook from another appliance.
If the tool is made with a threaded grip, then the end of the pin is threaded with the appropriate tool. You should not cut a lot of thread, as the body metal is quite thin.
After the tip is made, a weight is placed on the pin and bounded on the back side of the tool. You can do it with welding, or you can use a threaded stop. The second way is more advantageous, as it will allow the use of different weights depending on the required force on the end of the reverse hammer.
Reverse hammer with their own hands
Any kind of bodywork is expensive and requires special skills and tools. However, it is possible to save on the purchase of some by constructing them yourself. For example, a reverse hammer with your own hands can be made in an hour. This will allow you to do it yourself and control the process of leveling a dent in the body in hard to reach places.
In order to make this tool, you do not need a lot of time. You do not believe that you can make a reverse hammer with your own hands resilient and of high quality from a small assortment of parts? In fact, everything is very simple.
We take a pin and with the help of welding on one edge attach a hook. After making the tip, we put a weight on the pin, which we limit on the back side. Beforehand, you need to make a through hole in it for more convenience in use and fixing. This is very convenient, because you can make a reverse hammer with your own hands with a different weight of the weight at any time. This feature will be relevant when the damaged area of the car is too large. Also, do not forget about fixing the handle of the mechanism for greater comfort when working. It should sit tightly on the product, so it can be welded.
Pneumatic reverse hammer with their own hands
Such a kind of car repair as body repair. an operation is quite complicated. You will need a number of special knowledge, as well as devices and tools. An important role in body repair is played by the reverse hammer. This tool is simple enough and you can easily make it yourself. over, on this subject there are many recommendations and videos, as well as drawings.
Today you will learn how to make a reverse hammer with your own hands and how to properly use it for its intended purpose.
Stitching tool with their own hands: making a body hammer and its types

If it is decided to make a reverse hammer with a hook type of attachment, then a hook is made at the end of the pin. You can make it with a vice or pliers. Or use a welder to weld an existing hook from another device.
If the tool is made with a threaded grip, the end of the pin is threaded with the appropriate tool. Do not cut too many threads as the body metal is quite thin.

After the tip is made, a weight is placed on the pin and restrained on the back side of the tool. This can be done by welding, or using a thread stop. The second method is more advantageous because it will allow the use of different weights depending on the required force at the end of the backhammer.
What is a reverse hammer and what is it for?
This tool is a device that allows you to apply a certain amount of force to an area of metal with limited access. A device is used to straighten small areas of the deformed car that have suffered minor accidents.
Some areas of the car body can be leveled with an ordinary rubber hammer, using backhoe blows. However, most surfaces do not have this access. This is when a backhammer is needed. Its tip is fixed in the place of deformation, and by means of the weight, which is located at the other end of the device, is transferred to the surface by pulling jerk force.
Before making a reverse hammer, it is necessary to describe the varieties of this tool. You will need this to make a drawing of the device you need, and then make it.
