Knife for foam with your own hands. Cutting foam at home - knife or homemade machine? Nichrome cutter do it yourself

In construction I. finishing works By right, it takes a worthy place of foam. Its insulating and noise absorbing characteristics allow you to apply in the finishing of facades, country buildings, industrial enterprises. The design of the material consists of foamed particles that fill the gas cavity at molding. The cost of the material is not high, it allows you to apply it in any fields of activity, volume letters on advertising, information shields, etc.

Basic methods of cutting foam

The most best option for the thermal insulation of the structure is the foam. Usually, this goals are chosen not a dense structure, due to low cost. This causes inconvenience when cutting, the structure of the cells lifts, and with a small force you can break the design with your hands. The tool for cutting foam has various modifications, for sale ready-made options, you can also make a design with your own hands.

It is important to understand that the foam structure categorically refers to the impact of certain liquids. Acetone or gasoline destroys the structure of foam, the product will have to be reappeared. Temperature operation modes are no more than 50 °.

Cutting foam at home is performed by many undergraduate tools. For example, when working with small billets is the most simple way is the use of a stationery knife. The process occurs inaccurately, because The blade is quickly stupid, for better processing a knife can be heated.

Each of the devices has the advantages and disadvantages, it is important to mention the characteristics of the foam, to choose the characteristics of the foam, select a tool for cutting foam in size.

1. In business stores, you can purchase a special tool - a knife with a heating blade. The work of this adaptation is made from themselves, in order to avoid scaling and injuries. The main disadvantages of the cutting knife that they can cut the material of a certain thickness, for smooth operation, you need to competently place the product, spend time at this time.
2. A variety of heating knife can be a soldering iron with a special nozzle. Differs more high temperatures Heating, when working, it is necessary to be careful, the molten drop when entering the skin does not deliver joyful sensations.
3. The shoe knife for cutting foam is used with a long blade of up to 40 cm. The knife tip remains blunt, and the wide blade must be perfectly sharpened. Adjustment and sharpening produce every 2 meters of cut products. The process will be accompanied by a screech, you can exclude the unpleasant sound with headphones.
4. Thicker products can be cut with a tree with small cloth. The smaller the level of the teeth, the better the quality of the output part, however, the jackets and squeezes will still be present. The method does not require the application of special products, it is often used with long rectilinear foam cuts.
5. The most popular way is cutting foamflast string. The performance of this method is equal to industrial equipment, it is enough to build a small design. The string is used when working with foam of various grain and density.

Some cases, for the lack of any of the above from cutting tools, requires electrical intervention. Bulgarian is used with a minimum thickness disk. The work implies the presence of increased noise, garbage from particles of foam throughout the territory.

The processes of the work of the insulation of one residential premises can be performed by a manual type tool. The wire for exposure to the foam is used on a special stand pre-prepared. The design consists of nichrome wire, it is easily manufactured with your own hands. The connection scheme consists of two mounts, cargo for tension and power to the network. In cases where the production volumes are improved, special machines for processing foam.

You can buy them in specialized stores, and also make yourself.

Classification of machine tools

The design features of the aggregates do not differ from each other. In each of them, cutting occurs due to the rolled wire, fixed in a certain position. Some of the modifications have up to six adjustable strings, it allows you to produce more mass work. Foam cutting machines can be with a rotary table, a stationary fixed cutting element.

The devices are divided into several categories:

• equipment with software control that allows you to cut the figures of elevated complexity;
• portable cutting elements;
• transverse or horizontal cutting types.

The most complex designs in design allow you to work immediately above several planes of the product. Performance of foam cutting devices is designed for industrial purposes, for one approach, some models can process over 10 meters.

Foam cutting devices with their own hands

Home insulation materials are always available on sale. The foam glue is best on a flat wall, but when the protrusions are detected, it will have to adjust the shape of a foam. The cutting of the foam is performed both by purchased equipment and manufactured independently.

To build a structure, it is important to choose the parameters and drawings. The type of work also depends on the design and its size. The cutting of foam at home is carried out from the primary means, the main thing is to correctly pick materials. It is important to comply with the safety requirements, when cutting it is possible to slip the product, damage limbs.

In the process of heating the foam, evaporation is released, if inhaled, they may damage the worker's mucosa.

Homemade thermal knife for cutting

Adjust the shape of the insulation products, cut small products and blanks is possible by a thermal knife. For cutting foam, you will need:

• Croon type battery with output voltage 9 volts, or a totality of finger products.
• The nichrome fishing line is stretched between the plates, the length is not more than 10 cm.
• Multiple wires are connected to the ends of the wires to the battery.

The simplest cutter is possible to collect from undergraduate means, it will help to remove the chamders of the corners, perform the necessary fit of the parts from the polypropylene. You must install the power button, which will activate the device, this is done for convenient, safe operation.

Nichrome cutter do it yourself

Making with your own hands implies the presence of certain means. In order to qualitatively assemble a tool for cutting foam, you will need:

• nichrome wire, it can be purchased in the stores of radio components of the required size;
• 12 volt reduction transformer, as a computer power supply unit or charger Car battery;
• long needle;
• reostat, which makes it possible to regulate current strength;
• electric wires suitable for connecting length.

The device can be mobile or fixed on the table. The frame is made of wood, the wire is installed at a height of 10-15 cm, on adjusting screws. Screws that carry the fastening of nichrome wire must have a suitable length to adjust the height on necessary level. On one side of the screw hangs out the load to pull the wire for the direct level of the cut.

The impact of the current leads to the splitting of the wire, the foam is easily subjected to temperature effects. The edges are searched, it prevents the decomposition of the material structure. The cutting of foam begins after the appearance of a red shade on the wire, there is no need to bring incandescent to a high level, in these cases the width of the cut will be too large.

When performing the procedure, use personal protective equipment, mask, gloves. In the process of melting processing, there is a release of toxic vapors.

Cutting is made indoors with good ventilation or on the street.

Constructive features and principle of operation

The string when heated expands, adds to a length of up to 3%, the cutting cutter will not be high-quality, therefore a special mechanism is added to the design. When actions with a low frequency it is possible to apply the spring, it will gradually pull the wire to the desired state. Mass use implies rapid stretching, so it is better to use a suspended weight to one side of the string.

The foam cutting device is powered by energy sources with output voltage from 12 to 36 volts. Most good option You can select a laboratory transformer. The device is able to withstand high loads, produce smooth adjustment of the output voltage.

Specialized machines and prices for them

Made machines are supplied for mass production. There are modifications with six cutting elements, which allows you to quickly cut a large volume of foam in one run. Laser machines perform architectural purposes, capable of cutting various forms, materials in thickness.

Machines have excellent characteristics, may have functions of simultaneous processing of many elements, they have high performance. The price of devices is high, it is necessary to know exactly what kind of cutter is used.

FRP 01.

A simple design allows you to modify the device for various forms and dimensions of foam blanks. Foam cutting devices of different types Allow a number of actions. Implemented the possibility of cutting of robust parts, curly elements, insulation plates and signage.

Cut is performed by a machine by connecting to CNC. The cutting program is supplied complete, has various settings. The price of such a device begins from 110 thousand rubles, it is important to check before buying the functionality, reliability of the structure.

PSP "Contour"

There are modifications of machine tools for the production of elements. various shapes. The machine for cutting the expanded polystyrene is controlled in manual, has a simple design, rich functionality. Power consumption is not high, component details collapsible, which allows not worrying for transportation.

The cost of equipment begins from 40 thousand rubles. The main difference between market models from hand-made, these are carried out tests for safety, reliability of parts.

Independent manufacture machine for cutting

A full-fledged machine can be made at home. For the manufacture of the machine, a tabletop and frame of the desired width, as well as other details, is selected. The machine is made to cut foam plastic with their own hands from the primary means, by analogy to the smallest nichrome modification. There are several modifications and buildings of machine tools implemented in accordance with the terms of the parts.

Manual cutting polystyrene foam

Of all the above methods, manual cutting of foam plastic is not as expensive, the abundance of methods allows to affect foam products in accordance with the tasks delivered.

1. The easiest and without good way is cutting with great sharpened knives. The tip of the knife is left blunt, in the width of the knife must be distributed oil for lubrication, the speed of this method is not large, the cutting of small volumes is used.
2. Hot rune allows you to quickly produce work, but harms health.
3. Cutting a cold string is similar to the exposure of the saw, it is only necessary to make a productive design.
4. Cutting with the help of knitting.

Professional methods imply the use of the finished tool. High-quality and fast cutting is performed by using suitable devices.

Homemade machine on the table

If there is a large table and workplace, it will significantly save time and strength, because when applying manual ways The material cries, deteriorate. The homemade machine and its design cutting of foam plastic is performed by using a nichrome string.

The power supply is used suitable, which gives from 12 to 36 volts. The use of the network voltage is available, but only there is a wire coated with nickel, this method causes a blow to a current, which is significantly felt by a person.

Machine for curly cutting of foam

Complex geometric shapes can be treated with a special machine. The device allows you to make your own curly cutting of foam. The design is performed according to the same principles, only the nichrome wire is stretched vertically.

The mounting mechanism is suitable on the one hand, which makes accessible to move the product on the table top.

It has long been a typical construction in the fly. It is noticeable when visiting low-rise construction zones. Each house is individual, unique. But each home ownership requires insulation, if it has not been provided in the construction process. It is unlikely that foam producers will produce plates individual size With a small order volume. Have to cut. But how to cut foam in the device of thermal insulation of the building with their own hands?

Foamed expanded polystyrene foams are easy to handle cut. Before cutting the foam at home, you need to decide on the necessary accuracy and purity of the cut. After that select the necessary device for cutting foam from the following:

• saw (knife);
• string;
• thermosak;

There is no definite answer to the question: "What is better to cut?" as long as there is no certainty in volume and linear dimensions processed parts.

Foam milling is not in mind the extremely low mechanical stability of the material.

Just cut

When carrying out work on the insulation of the foundation, underground communications, overlaps under the tie, facade under the stucco, the special accuracy and evenness of the cut is not very necessary. Moreover, if the building has a simple facade configuration. In this case, you can use hand tool For cutting foam: knife, hacksaw, metal string.

Their use will lead to the loss of the pellets on the boundary of the cut and the formation of not a completely smooth edge. The presence of not tight fit of the slabs can be bonded by filling out the void by the mounting foam.

Straight cutting with a knife with small jar is justified with a thickness of a material in 50 mm, with a hacksaw, you can cut the insulation with a thickness of up to 250 mm. You can use a knife with a knife for cutting foam. Handsaw with fine tooth acquire in a construction store.

For ease of use of a string for cutting foaming (you can use old strings, for example, a guitar having a spiral navigation) is set to its ends. wooden handles. Cut the insulation reciprocal movements, as if they act as a two-handed saw. Large plates can be cut together. In this case, the cut sheet must be fixed.

Before cutting the foam, the cutting edges must be treated with liquid lubricant. This will create a certain comfort when working (improve gliding, reduce the noise).

Figure thread for foam using this tool is extremely difficult.

We use thermal knife

Cutting of foam plastic with its own hands with the use of thermionedly is justified with a plate thickness up to 50 mm. To cut off a polystyrene piece, a hot knife is promoted with an average speed, which provides the quality of the cut without breaking the fragments and melting edges.

Acquisition of a longer blade for this device is not entirely beneficial. With manual cutting it is impossible to draw a strictly perpendicular to the surface. Sheet's end will have a SCOS, which is extremely uncomfortable when installing. In order to better cut a thick sheet, it is necessary to cut the cut from two sides, blocking the hot knife half of the thickness or a little more.

We make and use thermosak

For cutting of foam, with its own hands, devices having a thin hot element are most often used. General principle Actions of any thermowel for foam one.

The heated element produces the separation of the material with the subsequent sealing of the open volumes. Applying thermosals for foam, we get a perfectly smooth cut, which is very important for high-quality warming work.

The acquisition of the factory apparatus for cutting foam plastic is economically impractical.

Only if it is not decided to do this professionally and constantly. In most cases, when cutting out curly elements is not required, you can use a homemade cutter for foam.

Make a cutter for foam with your own hands is quite simple and quite inexpensive. After completing the work, it will not lie by the dead cargo, take the place. It can be collected and disassemble as necessary. In the absence of need, its components can be used for other purposes.

Before making a cutter for foam, you need to cook everything you need:

• workpiece for the working surface;
• nichrome wire;
• laboratory adjustable transformer (LATR);

Chrometed nichrome wire You can use without a lowering transformer, but it increases the danger of electric shock.

• electric wire, fastening for it,
• springs for tensioning threads;
• adjustable mechanism.

In the manufacture and use of the device, follow the rules for the device and operating electrical installations.

Produce equipment for cutting foams Start with markup and trimming of the working surface. Its geometrical sizes determine in accordance with the size of the cut plates. Better if the table surface is more sheet area.

Install the racks (supports) with the ability to adjust. To do this, you may need a small device in the form of hexagon sleeves with internal thread. They will make it easier to adjust the height of the cut. Wire for cutting is stretched using springs. We pave and fix the electrical wire on different sides of the thread. The other end of the cable is connected to the Latra (in the absence of a latre, it can be replaced using an autotransformer to charge the car batteries). The device is ready to work.

Cutting foam at home should be carried out in compliance with security measures. During temperature processing, a toxic smoke is released. Therefore, we cut the parts from the foam or on the street, or use respiratory protection tools in the workplace equipped with exhaust ventilation.

The use of such a foam cutting device allows you to maximize the process of preparing insulation fragments.

Apply automated complexes

Issirs architectural design also require insulation. In order to preserve their expressiveness, there is a need to manufacture complex elements. How to cut similar details? More affordable option - Processing insulation milling. But the foam milling is not carried out for the reason that the milling pieces of the material bursts with its rotation.

Tight expanded polystyrene has a higher mechanical strength and is well milled. It makes everything you like: letter, digit, graphic element of any complexity. At least a hedgehog. Cutting the penurex is recommended at large angular velocities with a medium linear feed. To install the manufactured fragments on the facade uses Cerezite.

Laser cutting of foam plastic is the most advanced technology that combines a hot cutting tool and the accuracy of the automated system. Laser cutting of polyfoam allows you to produce parts of any complexity with the highest accuracy at a minimum level of waste. Laser cutting of foam plastic provides an absolutely smooth surface of the cut, using a hot beam of directional light, moving at high speed. For him there are no restrictions on the thickness of the material and the complexity of the element.

The choice of equipment for cutting used for foam plates and for extruded expanded polystyrene should be conscious. Answer technological requirements for finished products and be economically justified.

Polyfoam - lightweight, durable, good thermal insulation material, with which it is very easy to work. But he has one unpleasant feature: usually it is made in the form of plates enough large sizeswhich during the work has to be cut into pieces of smaller sizes. No matter how sharply the knife and saw were sharpened, it would be carefully cut with their slab, since the structure of the foam is destroyed, why it does not cut, but it cries. Therefore, for cutting you need to use a special cutter for foam.

Polyfoam, like any material requires cutting, it is for this that you need a cutter.

The simplest homemade cutter for foam

Such a cutter is not difficult to make your own hands. To do this, it is enough to take the finest guitar string and 4-5 big batteries For electrical lantern. By connecting sequentially all batteries into a single element, it is necessary to connect to its ends and fasten the heating string, closed the electrical arc. Thanks to the electric current passing, the string will be heated.

Image 1. Cutter scheme that allows you to cut flat sheets from a foam block.

In the place of contact with heated to the desired temperature, the string leaf of the foam will be instantly melted, divided into two halves, whose slice will be fused and smooth. But for normal cutting, the string should be warmed up to a temperature not less than 120-150º. When working, determine whether the string was sufficient enough, no work will be difficult, since with a cutting of foam plastic on the string there will be small bubble pieces. The longer such pieces remain, the lower the temperature of the string. But if they are not at all on the string, this means that this kind of thermal thermal is heated more than necessary.

Such a primitive cutter for foam plastic is able to easily cut 2-3 large layers of the material. But with large amounts of work, the batteries quickly sit down, therefore, in such cases, a cutter operating from the power grid is used.

Options for self-made electric plates for foam

Conditionally similar devices can be divided into groups:

• cutter for linear cutting of foam;
• cutter for figure cutting foam;
• cutter with a working metal plate.

But despite this separation, all the cutters have one common part.

For their manufacture, it is not without a lowering transformer.

Such a transformer must be calculated for a minimum of 100 W. The secondary winding should be calculated on the voltage of 15 V and have a cross-section of the winding wire no less than 1.5 mm.

Cutter for linear cutting of foam

Image 2. Scheme of the vertical cutter: 1 - cutting nichrome wire, 2 - load, 3 - frame, 4 - work surface.

Such adaptations are mounted from the working surface (you can use the table surface) with two vertical risers attached to the stands with two insulators connected to two contacts connected to the downstream transformer and stretched between the detectors of the nichrome filament, and also missed through one of the stands freely hanging cargo (image 1).

It works such a foam cutter very simple. Passing through the nichrome thread electricity It heats it, and the suspended load supports the thread in the stretched state, not allowing to be saved, because when heated it is quite stretched. Sometimes instead of the suspended cargo to pull the threads, use the spring attached to one of the risers.

The heated thread is easily cutting the body of the moving foam, turning it into flat sheets, the thickness of which depends only on the distance from the surface of the table to the stretched wire. All you need to do is withstand the uniform feed rate of the foam on the surface of the table.

For vertical cutting of the formation, another cutter design uses, in which the cutting wire is stretched vertically (image 2). To the working surface of thick plywood or chipboard (on the diagram is indicated by the number 4) the frame is attached, preferably cooked from metal profileBut it is quite suitable and made of wooden bars (3).

The frame design provides for the presence of a paw holder, to which the nichrome wire (1) with a suspended cargo at the other end (2) is suspended using an insulator, passed through a hole drilled in the working surface. Since the nichrome thread will be heated, the hole is better to make more and isolate the wooden parts, inserting a metal hollow tube of the hollow diameter into it, through the cavity of which and bring the end of the wire with the cargo.

Such a cutter for the foam not only easily cuts large pieces of foam on the blocks of the desired dimensions, but also allow, if necessary, cut squares, triangles, semicircles and other curly hole if necessary. To do this, it is enough to pre-conduct a marker on the surface of the foam line of the cutting line.

Figuction cutter cutter

If you need to cut the sheets of large size or thickness, which are impossible to place on the desktop due to the sizes, then in such cases a manual electric cutter is used, converted from a manual jigsaw or a labeling hacksaws, in which the cutting canvas is replaced with nichrome wire.

Image 3. A manual thermosal scheme: 1 - cutting nichrome wire, 2 - screw with nut and washer, 3 - textolite handle with a thickness of 4-5 mm, 4 - electric shuffle.

Such an electric cutter is not difficult to make it yourself. At the same time, for the convenience of figured cutting, you can make several working instruments. of different shapes (Image 3). The jigsaw or plumbing knife is removed, the cutting web is removed, and the electrical wire (4) is supplied to the handle (3). Despite the fact that the voltage will not be too high, still a handle, like other metal elements, is better to exhibit at least with an ordinary tape. Instead of the cutting cloth to the subordinate electric cable With the help of screws and nuts with washers, nichrome wire is fastened, curved in the desired manner (4).

As an option for a device of such a cutter, you can also use the device for burning on a tree or a pulse soldering iron. Such a cutter will be even more convenient, since the electrical wire is initially provided in the design of these instruments. To turn these devices into an electric marque for foam, it is enough to replace the heating instruments into them with a bunny nichrome wire, giving it the desired shape.

Such manual cutters are convenient because with their help you can not only cut the sheets of foam, but also cut into them all sorts of deepening, cavities, to remove chamfer, in a word, not just cutting the foam in pieces, and the real works of art.

Heat and sound insulation construction materials on the market are presented in a wide range, it is foamed polyethylene, mineral and basalt wool and many others. But the most common for insulation and sound insulation is extruded polystyrene foam and foam, due to the high physico-chemical properties, ease of installation, low weight and low cost. The foam has a low thermal conductivity coefficient, a high sound absorption coefficient, resistant to water, weak acids, alkalis. Polyfoam is resistant to the effects of ambient temperature, from the minimum possible up to 90˚С. Even after decades, the foam does not change its physicochemical properties. Polyfoam also has sufficient mechanical strength.

Polyfoam has even very important properties, it is a fire resistance (when exposed to fire, the foam is not smolder as wood), environmental purity (as the foam is made of styrene, then in the package can even be stored in food products). Foams do not arise fungi and foci of bacteria. Practically perfect material for insulation and sound insulation during the construction and repair of houses, apartments, garages, and even packaging for food storage.

In the shops building materials Polyfoam is sold in the form of plates of different thickness and sizes. During repair, it is often necessary for the sheets of foam of different thickness. If there is an electric foam cutter, you can always cut the sheets of the desired thickness from the thick plate. The machine also allows a figured foam package from household appliances Move into the plate, as in the photo above, and successfully cut the thick sheets of foam rubber for the repair of furniture.

How easily the foam on the homemade machine is cut, clearly demonstrates the video clip.

If you wish to make a cutter for foam and foam rubber, many stops the complexity with the supply voltage supply for heating the nichrome string to the desired temperature. This obstacle is overcome if you understand the physics of the question.

Machine design

The base of the fixture for cutting foam was a sheet of chipboard (wood chipboard). The size of the plates must be taken on the basis of the width of the plates of the foam, which are planned to be cut. I used the door from furniture with a size of 40 × 60 cm. With this size of the base, it will be possible to cut a foam plate with a width to 50 cm. The base can be made of a sheet of plywood, wide boards, secure the string of cutting directly on the desktop or workbench.

Stretch the nichrome string between two nails limit laziness homemade Masters, so I implemented simple design, ensuring reliable fixation and smooth adjustment of the height of the string in the process of cutting over the surface of the base of the machine.

The ends of nichrome wire are attached for springs, dressed on the screws M4. The screws themselves are twisted into metal racks pressed into the base of the machine. With the thickness of the base of 18 mm, I picked up a metal rack with a length of 28 mm, at the rate, so that the screw did not go beyond the bottom side of the base, and with the maximum twisted state, it provided a thickness of the cutting of foam 50 mm. If you need to cut foam or foam rubber sheets with more thickness, it will be enough to replace the screws longer.

To presses the rack in the base, a hole is drilled in it, a 0.5 mm diameter is less than the outer diameter of the rack. In order for the racks easily can be scored with a hammer in the base, sharp edges from the ends were removed on the sandpaper.

Before twisting a screw to the rack, the groove was driven by its head, so that nichrome wire during adjustment could arbitrarily move, and occupied the desired position.

To diligee in the screw the groove, first its threads need to be protected from deformation, putting the plastic tube or wrap with tight paper. Then hold the drill in the cartridge, turn on the drill and attach a narrow feet. A minute later, the groove will be ready.

To eliminate the savory wire, due to extension when heated, it is fixed to the screws through the springs.

The suggestion was suitable for the spring from the computer monitor used to tension grounding conductors on a kinescope. The spring was longer than was required, had to make two of it, for each side of the fastening of the wire.

After the preparation of all fasteners, the nichrome wire can be fixed. Since the current during operation is consumed significant, about 10 A, then for a reliable contact of the current-wheeling wire with nichrome wire, I applied the method of fastening the twist with compression. Thickness copper wire When current 10, it is necessary to take a cross section of at least 1.45 mm 2. Select the wire section for connecting nichrome wire from the table. In my disposal there was a conduction with a cross section of about 1 mm 2. Therefore, each of the wires had to make 1 mM 2 from two cross section connected in parallel.

If the electrical parameters of the nichrome wire are not known, then you must first try to connect a low-power electrical appliance, such as an electric light bulb 200 W (flows about 1 A), then a heater per 1 kW (4.5 A), and so increasing the power of the connected devices while nichrome Wire cutter does not heat up to the desired temperature. Electrical appliances can be connected in parallel.

The disadvantages of the last scheme of connecting the nichrome spiral should include the need to determine the phase for the correct connection and low efficiency (efficiency), electricity kilowatts will be expensive.

Foam cutter is a fairly simple tool that works on the principle of burning material. It can be bought in building materials stores. it the best wayIf a large amount of work is to be. In the event that the cutter is needed for 1-2 days, it is easier to do it yourself, since the next time this tool may need after many years. But you can use this option: to rent a cutter in one of the construction companies, after calling and finding out whether they will provide such an opportunity.

How to make a cutter for foam with your own hands?

The easiest way to make a cutter for foam based on the wood burning device. In the paper it will take a nichrome wire that heating will cut foam. The process of manufacturing the tool is simple: on a standard metal pin for burning, suitable spring-sized diameter. It should make this item tightly. The spring is inserted with a straightened wire from nichrome. It can be found in any hair dryer for drying hair. Include the device for burning and when the spring is heated, proceed to operation with foam.

For cutting of this material, you can also use a soldering iron with a capacity of 60 W. You need to choose such a tool in which the plate knife is used instead of the usual sting. After heating, it can easily reduce the foam or any heat melting synthetic material.

To work with the leaf foam, you will need a steady basis on which the soldering iron is fixed. This will provide the quality of the cut. As a support, you can use heat-resistant plastic, a piece of plywood or a board. At the bottom of the base, you need to make low legs. They are needed in this design.

Closer to one of the sides of the supports fasten the vertical rack from the metal tube. It has two brackets in which the soldering iron is inserted. The longer the bracket web, the farther from the vertical rack is a soldering iron.
A copper plate is inserted into the cut of his lamellar sting. The knife edge is sharpened at a small angle. The degree of heating of the cutting element is determined by the experimental way. Such a cutter is very convenient for work as with sheet Material, that and with figure molding. It should be noted that the width of the cut will be at least two times greater than the thickness of the copper plate. This must be taken into account when performing finishing works.
