DIY reverse hammer: mechanical and pneumatic

Homemade spotter can be made from the old inverter. But for this you need to know what scheme the design is assembled. Spotter’s work depends on a number of mandatory components:

The operation scheme is determined by two diagonals. The power of the transformer of the first diagonal is higher than the second. Therefore, it takes the voltage after turning on the apparatus. Electricity enters the secondary winding along the diode bridge and relay into the capacitor. Thanks to this system, charging is ensured. In this case, the voltage is passed in the transformer, and does not accumulate. With this launch scheme, the thyristor closes.

To start welding, you will need to open a thyristor. After turning off the charging of the capacitor, the secondary winding of the transformer will receive a sufficient indicator of the current for welding. You can consider in more detail the elements of the scheme in the work on the plan.

What is a reverse hammer

Reverse hammer for body repair. a tool designed to remove dents from the surface of the car. As a rule, these defects cannot be straightened with conventional tools, so the reverse hammer often is used for rikhty dents on the thresholds, arches and racks of the vehicle. The tool in the classic version is a 50 centimeter pinproof pin. The diameter of the steel rod is two centimeters. Two elements are placed on it: a rubber sleeve on one side, and on the other. a metal washer. It holds a hammer in a stable position and protects the tool body from vibrations that arise as a result of striking.

The tool is used for ri. small damage in area.

The device for raising defects is equipped with additional clamps and metal hooks, with which the brackets welded to the body of the machine are captured during the ri.

The use of the reverse hammer largely depends on the location and complexity of the defect. There are several types of tools:

For point.to.line ri. dents on the surface of the body of the new car, it is recommended to use vacuum hammers. The scheme of its work is concluded as follows: with the help of suction, the tool is attached to the restored area, then the handle is pulled “on itself”, and as a result, due to the compression of the air, dent is aligned. The principle of operation of this variety of the device allows you to eliminate defects without damage to the paintwork of the car body.

The use of pneumatic tools is necessary to eliminate serious damage. The hammer is connected to a powerful compressor, as a result, the mechanical effect on the damaged area is enhanced. The device is attached to the body of the machine using special hooks. Before using the device, if necessary, the paintwork is removed from the damaged area.

Spotter is a welding machine with which an additional element is welded to the car body. It can be an iron rod or a special hook. Then they cling to the protruding part with the back hammer, and the damaged area is aligned.

Before welding, parts are thoroughly washed, remove the paintwork and degrease from it.

The tool with adhesive overlays is attached without the use of a welding machine. Reliable fastening provides special adhesive composition, after eliminating the defect, the pad is cut off, and the damaged paint coating is restored.

The purpose of using the hammer is to equalize dents. However, with it, some spare parts dismantle it. So, to remove internal bearings, use a tool that has a special hairpin in their design.

How to independently make a reverse hammer from an old shock absorber

VAZ shock absorber racks are best suited. After parsing the old car, do not rush to take the old parts in scrap metal. Having attached some effort and ingenuity, it is easy to make a reverse hammer from a shock absorber.

Device design

First you need to deal with the design. In the classic version, a mechanical reverse hammer is a pin 50 cm long and with a diameter of 15-20 mm. A handle is fixed on one side, on the other. a fixing device (hook, vacuum suction cups, a bolt with a thread). A steel sleeve is glides freely between them. a weight.

Necessary materials and tools

After the correct disassembly of the rack, you will have the necessary material to build a reverse hammer with your own hands from the shock absorber.

Prepare a container for lubrication flowing from the pipe cavity during cutting.

Dismantling the shock absorber rack

The upper part of the old spare part and the rod is needed to create a useful adhesive device.

Squeeze the part in a vice, substitute dishes to the place where you will make a cut. Dip the pipe to a plate with a spring. Work carefully, do not hook the stem.

Remove fasteners from the rack, other details. You have a rod and top cover left. Remove from the last oil seal and sleeve.

Manufacturing a reverse hammer

The freed stem will serve as the basis from which a functional reverse hammer from the shock absorber will be obtained. It remains to supply the pin in three details: this is a hilt, a load-gyra and a nozzle.

• From one edge of the rod. where the thread is. attach the handle. Fix it by welding the nut from both sides. Process the spaces of the welds according to the rules: remove the corner grinder and unevenness, polish.
• From a piece of the shock absorber rack and the pipe of the desired diameter selected for it, make a movable weight. Mount the element on the main pin.
• On the opposite of the handle, the end of the rod attach the nozzle.

How to make a handle

For convenient use of the device, find and fix at one end of the main working rod rubberized side handles from power tools. If there were no suitable details, adjust any clamp that will be comfortable in the hand.

As an option, use a piece of fuel hose. Fasten it on both sides with nuts.

How to make a moving weight

This important detail will go the rest of the pipe from the shock absorber rack. The reverse hammer from the shock absorber rod is useless without cargo-giria: its weight should be at least 1 kg.

• Pick a pipe of smaller cross.section than a piece from the rack, but more diameter of the rod (the load should glide freely along the rod).
• Insert one tube into another so that they do not contact the walls.
• Distribute the details, brew one end, leave the second open.
• Melt the lead, pour into the gap between the pipes. After the metal metal is hardened, I am ready to work.

Return hammer from a shock absorber rod

Lead can be “mined” from the old battery and melted in the case from an unnecessary oil filter. Or by laying pieces of lead between the walls of the weight, direct the flame of the gas burner to the part.

Give a cooled gyra an aesthetic look (cut the influxes from welding, go with sandpaper), put on a beautiful heavy element on the stem. DIY reverse hammer from the shock absorber is ready.

There is no reverse hammer? Make it yourself from the old shock absorber! detailed instructions

Updating the spare parts of your car, do not rush to get rid of old details: some of them can give a second life. For example, shock absorbers’ racks can continue their service in a different quality and come in handy for the analysis and repair of the machine, if you make a reverse hammer out of them. With its help, you can disassemble different details, dismantle spacecraft, bearings, brake drums, and in addition, it is indispensable for manual body ri

First of all, the dismantled spare part must be correctly disassembled. If the shock absorber is removed from the VAZ car, further work will not be too complicated. Of course, standard tools will also be required, which is usually equipped with a garage of a motorist who prefers independent maintenance and repair: a vice, corner grinder, manual welding machine, gas burner or crucible (for swing melting).

Method for using a reverse hammer

The method of aligning the body using the tool made is simple, but will require some effort. First of all, you should fix the tip on a curved surface. Further, the boards on the weight of the harvest is aligned as it should. With insufficient efforts, you should change the weight. To align a large section of metal, you can weld a couple of goals that will be on the same line. Then you should put on the pin. Next, the rod should be fixed with dick, which is pulled together with the iron, while smoothing everything to the desired state. But it is worth being careful, since you can damage the body part by causing additional damage.

The car body can have dents of different sizes. And at the same time make a reverse hammer with your own hands, suitable for different irregularities, is easy. It is enough to make the possibility of changing the weight to the mechanism. Just changing weight with big damage. Sometimes you should weld additional goals. Then the tool will work smoothly. But do not forget that you can damage the car by overdoing. Therefore, it is worth making smooth movements when repairing the machine. Thus, each motorist with proper repair will be a satisfied homemade device. After all, this mechanism is simple to manufacture and copes with its work perfectly.

We make the reverse hammer ourselves

In order to create such a reverse hammer yourself, the author of this article needed very little metal. The picture has a drawing to this hammer. Anyone who will do the right to create with their dimensions. After all, the main goal is to work!

By the principle in such a hammer: a rod on which on one side is a hook, a pen, a stop, a fight. We take a hammer in one hand, and the second we drive the fighting by hitting the stop. The author took a pair of not large pieces of one diameter from sheet metal, and one piece of metal in a thicker, two pieces of pipes are one more size, the second smaller size, but a little longer than the first and another handle. The author does not indicate the dimensions in the text, your dimensions may differ from the size of the author. The sizes of the author in the picture are above.

From the metal you need to make a circle, its size is equal to the diameter of the pipe that more. In it you need to drill a hole equal to the diameter of the pipe smaller. Next, the smaller pipe must be welded as in the picture.

Explanation from the author: at first he cut off the square in size, a little larger than the size of the pipe, then he made a hole under the pipe that smaller and welded it, and then turned it under the circle of the desired size. The picture has another option. Everyone has the right to do in their own.

On the received workpiece, the author put a piece of the pipe large and scald it. Then the author made another puck, exactly the same as at the beginning.

Then he cut the pipe that was smaller, with a margin for welding, he left 2-3 mm. The picture shows a fishing line for a cutting trimmer.

Then he filled the void with dry sand. Put on top the finished second washer and scalded everything.

It turned out a fight.

At the next stage, the author took: metal for a stopper, pen and rods. The author cut a bar with a margin for a hook bend. The stopper should be from the metal thicker so that the stoop would not bend from the blow. The author took not fat, but he, but, in the form of a bracket. The pen can be used from everything that is suitable (or you can just weld a small tube.)

He bent one edge of the rod crocheted, put on a fight, and put a stopper on the second edge and boiled from the side of the handle. The pen also welded here (all welding should be on the other side where the handle is, but not from the side where the fight.) The author turned out to be such a hammer.

Device design

You can find a reverse hammer for a body repair on numerous sites. But before designing it is important to determine the goals for which the tool will be used. A reverse hammer for rikhty can be done in half an hour with your own hands, but you need to select the scheme in advance. The easiest way to assemble a model with an adhesive base or with interchangeable hooks on the thread.

The first step is to decide on the size of the hammer. Typically, 50 cm lengths are enough to ensure prolonged work and convenience, however, reducing this number is possible depending on individual needs or the availability of the necessary materials.

The second stage is made a clear drawing on which each detail is carefully drawn. Thanks to this, the number of components and the degree of their readiness for assembly becomes clear. Most often, it is at this moment that you can think in advance and make hooks for stretching various sizes. Since the reverse hammer can be made with one or more cargo, such a variety of nozzles will allow you to work with dents of various severity. For example, with specific damage, welding of several loops on one straight line with the subsequent extension of the pin for stretching one plane is possible.

This method is not suitable for any dent, but it allows you to reduce the arising deformation forces in the metal, which allows you to do work faster and with minimal damage.

A reverse hammer from an anchor bolt to shoot bearings and not only

The reverse hammer that I made from the anchor bolt with my own hands will be useful not only for knocking out small bearings, this craft can be found a lot of applications, I think that everyone should have such a hammer in the garage.

So, what will we need for this, and the first thing the anchor bolt is certainly required, its size depends on your needs, in the end you will understand why.

We will also need an iron rod or a rod along which the fight will “run”, its thickness is 13 mm, and the length is 60 cm.

First of all, I welded an anchor bolt to the rod.

Then, in my garage, such a weighty stray was lying in my garage)),

I don’t know how to call it differently, well, it just approached me, I just had to slightly drill the internal hole to the size of the rod along which it will “run”.

At the other end, the rod welded a nut, and perhaps our craft is ready. Nothing complicated, almost three details, and how much will it be from it.

Well, now you need to try, take the lid from the old engine and try to remove the internal bearing from it.

To do this, we insert an anchor bolt into the bearing and twist it until it closes there, and then just a back hammer and the bearing jumped out.

So everything works with a bang, my garage was replenished with a new and necessary craft).

PDR brands

Now there are many different firms producing PDR tools and accessories. It is better not to buy cheap analogues of unknown firms or even sets without a name. Tools of well.known, proven brands are thoroughly tested, tests with experienced craftsmen. Secealists of PDR manufacturing companies maintain feedback with masters, and also take into account requests for the necessary modification of some tools.

The highest quality and proven ones are the tools of American companies such as Dentcraft Tools, A.1 Tools, Pdr Face Tools, Ultra Dent Tools and others. It is also worth noting Keco and BlackPlague PDR, which sell innovative tools and materials of the adhesive system for drawing complex deformations.

Backdrops for a reverse hammer

The design of the holder depends on the purpose and the method of attachment to the body, bearing, hub or other pressed part of the mechanism. One, albeit the most convenient nozzle in appearance, is not able to help a locksmith constantly engaged in rikhty and repair. In a small workshop, it is advisable to have a universal tool with a set of several convenient latches of different types.

Reverse hammer: device

This term is understood as a metal pin with a length of 50 cm and a diameter of 2 cm, one side of which is represented by a sleeve, and the second is a small steel puck that holds the sleeve and protects the case from shock vibrations. Many reverse hammer models are equipped with several captures-tricks serving to capture brackets welded to the body.

The reverse hammer is designed to align small dents, to which there is no direct access, on the back of the details on such details as for example: thresholds, arches and racks.

It should be borne in mind that the tools in question are not suitable for processing large body elements, such as the roof, hood and trunk lid.

In addition, using reverse hammers, it is possible to eliminate only small dents. In the case of, for example, violations of the geometry of the body, other repair technologies will be required.

Reverse hammers are classified into four types:

The type of instrument determines the technology. In the case of using reverse hammers of the last three types, it is first necessary to completely remove the paintwork from the surface of the processed part of the body by grinding. The difference between a vacuum tool is that it is used without removing the paintwork, without damaging it and without violating the integrity.

Application

Do.it.yourself rikhty process using a reverse hammer is performed in the following order:

• First of all, it is necessary to clean and degrease the working surface.
• Then the paintwork is removed from it by grinding.
• Round repair washers are welded to the processed section of the body.
• Further at the end of the reverse hammer, a metal hook walking includes.
• They cling to the puck and, holding it with one hand by the weight, and the second. by the handle, the first is directed to the second with sharp movements. In this case, the surface of the body part is aligned. It should be borne in mind that the power of shock directly determines the level of leveling.

Dents lead to the formation of internal compression and stretching stresses, which, when ri. can change inpunctional. For successful implementation, it is very important to determine the nature of the defect. For example, when eliminating a dent located in the central part of the body part, new defects can be formed by stretching.

Therefore, during the process, it is necessary to control changes in the corrected dent and in order to avoid the formation of new defects to carry out it from the edges to the middle of the defect in a circle.

If the work is performed correctly, the surface will take the original shape, and the deformation voltage will be eliminated.

Self.manufacture

Making a reverse hammer at home with your own hands is quite simple. This does not take much time, and does not require special materials and tools. For a more visual understanding, you can watch a video on the Internet. The primitive drawing will also not be superfluous.

For the manufacture of this tool with your own hands, you will need the following:

• metal pin about 50 cm and 20 mm in diameter;
• cargo that has an internal hole;
• thread cutting tool (optional);
• welding machine;
• Corner grinder.

If it is decided to make a reverse hammer with a hook type of fastening, then a hook is made at the end of the pin. You can make it using a vise or pliers. Or weld a welding machine a ready.made hook from another device with a welding machine.

If the tool is made with a threaded capture, then the thread is cut at the end of the pin with an appropriate tool. You should not cut a lot of threads, since the body metal is quite thin.

After the manufacture of the tip, a load is put on the pin, which is limited to the back of the tool. This can be done by welding, or use threaded emphasis. The second method is more predominantly, as it will allow the use of loads of different weights depending on the required force at the end of the reverse hammer.

Brief instructions and tips on the use of tools

Again, to clearly understand how this happens, the easiest way to watch the video. If this is not possible, then the procedure for working with this device is approximately as follows:

• The tip is fixed on the deformed area of ​​the body;
• The details of the cargo are aligned to the desired position;
• If the effort is not enough, then the load changes to a heavier.

When stretching a relatively large section of the metal, you can weld several goals on one line and pass through them the pin. To do this right, it is advisable to watch the video on this topic. Then this pin is hooked, which is welded to the device and is pulled together with the metal, aligning it to the desired state. When using this method, you should be careful, since welding of a large number of washers can excessively pull the metal, and ruin the body part.
