When carrying out heat-insulating and finishing work in which polyfoam is used there is always need for its cutting. For this purpose use special purpose tool – the cutting torch. If it is absent, make independently.
Where to take the cutting torch for polyfoam?
The cutting torch for polyfoam – quite simple tool working by the principle of burning of material. It can be bought in shops of construction materials. It is the best option if the large volume of works are necessary. In case the cutting torch is necessary for 1-2 days, it is simpler to make it independently as next time this tool can be necessary in many years. But it is possible to use also such option: to rent the cutting torch in one of construction companies, previously having called and having found out whether they will give such opportunity.
How to make the cutting torch for polyfoam with own hands?
It is the simplest to make the cutting torch for polyfoam on the basis of the device for burning out on tree. In work the nikhromovy wire which heating up is required will cut polyfoam. Process of production of the tool is simple: for burning out get the spring suitable on diameter on the standard metal pin. It has to fit this part tightly. Insert the straightened wire from nichrom into spring. It can be found in any hair dryer for drying of hair. Turn on the device for burning out and when the spring heats up, get to work with polyfoam.
For cutting of this material it is possible to use also the 60 W soldering iron. It is necessary to choose such tool in which instead of usual sting the lamellar knife is used. After heating it without effort will cut polyfoam or any thermofusible synthetic material. Work with sheet polyfoam requires the steady basis on which fix the soldering iron. It will provide quality of the machine cut. As support it is possible to use heat-resistant plastic, piece of plywood or board. In the lower part of the basis it is necessary to make low legs. They are necessary in this design. Closer to one of the parties of support fix vertical rack from metal tube. On it two brackets into which insert the soldering iron have. The bracket cloth is longer, the further from vertical rack the soldering iron is located. Insert copper plate into section of his lamellar sting. The edge of knife is sharpened at a small angle. Extent of heating of the cutting element is defined by practical consideration. Such cutting torch is very convenient for work as with sheet material, that and with figured molding. It is necessary to consider that width of the machine cut will be at least twice bigger, than thickness of copper plate. It needs to be considered when performing finishing work.
