Cutting steel pipes at an angle of 45 degrees. How to make a pipe sweep at any angle. Cutting pipe at forty-five degrees or another angle. Marking of pipes of round section

19.04.2020

Pipes are a widely used building material. They are used in the installation of various systems. A common thing during the installation process is the situation when pipes need to be joined at an angle. However, the technology for the production of such works is not quite common. To create such a connection configuration, cutting the pipes at an angle is required. Consider how such operations are performed and what cutting methods exist.

Considering the methods of work - cutting straight or at an angle - one should take into account the different material of the products being processed. So, sleeves made of polypropylene or thin copper are easier and easier to cut than thick-walled steel pipes.

Plastic products of small diameters are cut at the desired angle using special scissors. In this case, you can control the angle with a conventional protractor.

It is very common to cut pipes in the process of working with these installation elements. A popular tool for such cases is the so-called grinder. This tool cuts straight and at an angle.

The most common installation need is cutting water or other pipes at an angle of 45º. Let's find out what devices can be used for cutting at this and other angles.

Paper pattern for pipe

To perform a relatively accurate cut, you can apply a simple technique, where an ordinary sheet of paper acts as a kind of pattern. For example, A4 printer paper is well suited for creating patterns. Previously, the sheet is marked under the square using a ruler. The diagonal of the square should be equal to length circumference of the pipe to be cut. Excess parts of the sheet are cut off.

The easiest way to get a marking line on a pipe for making a cut at an angle of 45 degrees. A regular sheet of paper is used, which is superimposed on the pipe body in the cut area

Bend the sheet diagonally, aligning opposite corners.
Rotate the resulting triangle so that the hypotenuse line is perpendicular to the axis of the pipe.
In this position, wrap the pipe surface with paper, aligning the extreme points of the hypotenuse together.
Make a cut mark with a marker along the line of any of the legs of the triangle.
Cut the pipe along the marked line.

In this way, it is quite convenient to mark and cut pipes at an angle of 45º in the diameter range from 32 to 63 mm. For greater convenience of marking, it is recommended to take thick but soft paper. You can also use paronite and similar materials.

Cutting angle calculation programs

The technology of cutting according to patterns allows you to get different cut angles. But to form a pattern at angles other than 45º, it will already be necessary to perform mathematical calculations and, according to the calculated data, cut out a pattern from paper or similar materials. True, there are computer programs designed to save the master from making calculations. Patterns for cutting pipes such programs are printed on a printer.

This is how the window of a computer program that calculates the cut angle for a circular section looks like. According to the results of the calculation, a pattern is drawn, which can be printed by a printer. A template is cut out according to the pattern

A simple calculation program, created on the basis of MS Excel, allows you to calculate and draw up a pattern for almost any values of pipe diameters and required cutting angles. All the user needs to do is enter the appropriate values in the "Outer Diameter" and "Cut Angle" cells. Based on these parameters, a pattern will be formed, which can be sent for printing.

An example of a pattern obtained by the calculation method in the popular Excel program. The calculation of the points of passage of the curve is carried out on the basis of only two specified parameters - the diameter of the pipe and the required angle of cut

The disadvantage of the program is that it does not take into account the thickness of the pattern sheet, which leads to minor inaccuracies.

Pipe cutting miter box

There is a simple tool, often used in everyday life, mainly for woodworking. It's called a stool. So, the same device is suitable for cutting pipes, and at different angles. The miter box is commercially available, but if you wish, you can always make it yourself and adjust the design to the desired pipe diameter:

Take a wooden board with a width equal to the diameter of the pipe, 400-500 mm long.
Take two more boards of the same dimensions, but increased in width by the thickness of the first board.
From three boards, assemble a structure in the form of an inverted letter “P”, where the first board is installed as the base.
In the central part of the structure, mark out a rectangle, the two sides of which run along the inner borders of the side boards.
Divide the rectangle diagonally and along the lines obtained on the upper edges of the side boards, make cuts down to the base.

In this way, a template for cutting at an angle of 45º is made. But with the help of a protractor, you can mark almost any corner and make cuts for a pipe cut for a specific angle. The advantage of the miter box is that the tool is suitable for repeated use. Working with the tool is acceptable up to such a degree of wear of the walls of the slots, as long as they can provide high cutting accuracy. It is recommended to make tool walls from a material of higher strength than wood.

This looks like a possible design of the miter box - a device thanks to which it is also possible to cut pipes at different angles. However, the miter box, as a rule, is convenient to use for cutting pipes of small diameters and with a small wall thickness.

The advantages of the method are obvious - simplicity, ease of manufacture of the instrument (miter box), economy, versatility. The disadvantages of working with this option of equipment is the need to adjust the dimensions of the miter box to the pipe diameter, provided that an accurate cut is made. That is, for each pipe you have to make your own tool.

Also, using a miter box, you can cut a pipe only with a hacksaw for metal or a secateurs (for plastic products). To work with thick-walled metal pipes under the cut with a grinder, this tool is not suitable.

Simple cutting tool

Metal products of round and rectangular shapeshaving sufficiently thick walls, it is convenient to cut at an angle using uncomplicated equipment of electromechanical action. The cutting element of such a tool is a cutting disc or circular saw, mounted on the motor shaft. In turn, the electric motor with a cutter is part of the entire equipment, which includes a work table, a pendulum support, a clamp.

Electromechanical device for cutting tubular elements, including at different angles. It uses a disc cutter and a simple mechanical system for fixing the pipe in different positions

To install the pipe at the desired angle, followed by its fastening, an ordinary clamp and two metal corners are used. One corner (short) is attached to the base of the swivel mechanism - the pendulum. The second corner (long) is in a free state.

Pipe laying and cutting procedure:

The required cutting angle is set by the rotary mechanism (for example, using a ruler and a protractor).
The found position is fixed with clamping screws.
A pipe is laid between the short and long corners and pressed with a clamp screw.
Voltage is applied to the motor.
By applying a slight pressure force to the cutter disc, the pipe is cut in the right place.

The advantages of this technique are fast work, accurate cut, the ability to process a large number of pipes in a short period of time. Disadvantages: restrictions for use in domestic conditions, increased noise, work with pipes of only small and medium diameters. In addition, the process of cutting with a tool is performed stationary at a distance from the installation site, which is not always acceptable.

The nuances of working with a rectangular section

To perform cutting of products of rectangular section, it is recommended to prepare template cuts of corners in advance. They are easy to make from a metal corner, having previously marked with the same protractor.

Cutting rectangular pipes (profile elements) at the desired angles is usually done using templates. Such templates are made from metal corners of different sizes.

Marking can be done at different angles. To use a template in business, it is enough to attach it to a rectangular pipe in the right place and mark the cut line. Then, with any suitable tool, cut along the intended line.

Precision cutting machines

Among branded devices that could be used in everyday life for cutting at an angle, you can pay attention to Italian-made equipment. band saw machine Mini Cut from MASS is a small-sized device with a manual clamp, for working not only with pipes, but also with angles, bars, profile elements.

Convenient and productive machine for cutting pipes of small and medium diameters. The cutter is made on the basis of a strip steel blade, which can be installed to perform a cut at an angle

The machine supports setting the cutting angle from 0 to 45º. The procedure is carried out using a tape blade at a speed of 45 reciprocating movements per minute. The device is equipped with a 370 W electric motor, which is powered by a household network. The maximum allowable diameter of the cut round pipe is 65 mm.

Industrial models (on the example of BSM)

There are special machines for industrial use to perform precise miter cutting operations. A good example is devices manufactured under the BSM brand. The machine tool manufacturer is the German company Rexinger. True, the machines of the BSM series are designed exclusively for working with polypropylene pipes of sufficiently large diameters. Processing of products such as PP, PVC, PE, PVDF is supported.

Industrial machine for cutting tubular products from polymers. Designed to work with products of large diameters, but has equipment for processing pipes from 50 mm. The machine provides cutting in a wide range of angles

The cutting tool of the machine is a band saw, thanks to which the cut is made at angles from 0 to 67.5º. The accuracy of the process is ensured by the laser cut recognizer. Despite the configuration of the device for products of large diameters, a special table can be used, with which pipes of small diameters (50 - 200 mm) are also successfully cut. A wide range of BSM devices is produced.

The use of thermal methods

In addition to mechanical methods, thermal methods are often used, where welding or cutting machines work as a tool. For example, an oxy-fuel cutting torch or a conventional welding machine (DC/AC). With the help of such devices, thick-walled metal pipes are available for cutting. However, it is extremely difficult to obtain a perfectly even, high-quality cut using electric welding or gas autogenous welding.

Cutting technology using electric welding and autogenous welding is widespread. The technique does not provide high cutting accuracy, but this factor is often not decisive when installing pipes.

Usually, after thermal cutting, the products are subjected to additional processing. The cut line is aligned, the values of the required angle are adjusted. This approach is not economically viable, as it is accompanied by additional costs for machining. As a rule, a thermal cutting technique is used in the conditions of the industrial and production sphere. True, housing and communal services also often resort to this technique.

Thermal cutting is also used to work with plastic material. There are devices - thermal guillotines. The sharp thin blade of such devices is heated to a high temperature, after which the cut is performed.

Thermal guillotines support cutting at an angle, and this is their advantage. However, to work with more rigid materials than polyvinyl chloride, wood, chipboard, these devices cannot be used.

Video: how to cut a pipe

The video presents calculations and shows a workshop on how to cut a pipe at angles of 45 and 90:

For each individual installation case, you can choose the most convenient and least expensive cutting method. The specific choice depends on the material of the pipe, its diameter, wall thickness. Using simple marking methods, you can get a fairly accurate angle at which you want to cut the workpiece. At the same time, referring to a complex calculation technique, it is possible to cut at non-standard angles with high precision.

When installing a pipeline, it is often necessary to cut the pipe at a certain angle. Accuracy plays a big role in this task. There are several easy wayshow to cut a pipe at an angle.

An incorrect cut of the pipe will lead to the impossibility of mounting the structure of the form that was originally conceived. For example, if you plan to rotate the system by 45 degrees, then you need to cut the pipe at 45 degrees. To complete the task, you will need marking tools and a grinder (it can be replaced with a hacksaw).

Paper corner marking

Paper sheet marking is one of the easiest ways to complete a task. Requires a square sheet. It folds exactly diagonally. The resulting template for cutting pipes must be wrapped around the product so that the long side runs parallel to its cross section.

Then on the smaller side an angle of 45 degrees is formed. It remains to mark the cut line with a construction pencil or marker on a sheet of paper.

Marking method using a container of water instead of a pattern

This marking method is suitable for small diameter pipes, which are planned to be cut at a certain angle near the edge. First you need to prepare a deep container with water. It marks the planned angle of inclination. Now you need to carefully immerse the end of the product in the liquid, tilt it to the mark, and then pull it out.

As a result of such actions, a clear line of contact with water will appear on it, it must be highlighted. On it, the pipe is cut at an angle. This method is best suited for jobs where multiple markings are required.

Using the PC program

To implement this method of marking pipes for cutting, you will need a computer with special programs. First you need to draw up a drawing, which indicates the transverse dimensions of the product, as well as the planned cut angle. You need to get a virtual template.

Print it out on your printer. And here it is worth understanding that the larger the diameter of the pipe, the more sheets will be required to print it. Then you need to carefully cut out the details of the drawing from all pages and glue it, it is best to use stationery tape for this. It remains to attach the template to the pipe and apply the markup.

This method of solving the problem is highly accurate. All necessary programs can be downloaded on the Internet, they are free to download and use. There you can also find a template for cutting pipes at an angle. All you have to do is print it out and cut it out. To perform marking, the pattern simply wraps around the pipe.

How to cut a profile pipe at an angle

The marking of the profile pipe is different from the round one. Its manual execution can lead to significant errors. The best way to solve the problem is to create a cutting template from the same profile, but with a larger diameter.

You will need a small piece of profile pipe. On it, using a goniometer, mark an angle of 45 degrees. Now, with the help of a grinder, it is necessary to cut off part of the workpiece along the marked line. The edges of the cut must be sanded, defects eliminated. It remains simply to insert the original product into the template for cutting pipes at an angle. Then you need to apply markings along the cut line of a larger profile. And already the pipe itself is cut along it.

The text describes how to cut a pipe at an angle of 45 degrees. When the markup is already completed, it is recommended to use the grinder. It will help you make a straight cut. You can replace it with a hacksaw. It will also be possible to cut the product by welding, but experience in handling the tool is needed, otherwise there will be irregularities.

Now in hardware stores you can find special tools for cutting pipes. But it is easier and cheaper to make a template yourself.

Quite often, when performing various construction or repair work, it becomes necessary to cut the pipe. It can be plumbing work, laying pipelines or installing heating systems, but in any case, you need to know how to cut the pipe evenly. Some features of this task will be discussed below.

45 degree cutting

One particular example of this situation is the need to cut a metal pipe at an angle of 45 degrees. Such material cutting is often required when laying plumbing or heating systems. In this case, you have to deal with steel pipes. For these purposes, conventional pipes of cylindrical section are usually used. If we are talking about the installation of some metal structures, then profile pipes of rectangular or square section are more often used. The main problem here is that in order for the elements to be joined to match, the cut must be as even as possible, which means that special attention should be paid to marking the material.

When cutting at an angle is required, a simple square sheet of paper can be used as a marking template. It must be folded strictly diagonally, and then wrap the pipe with a template. In this case, it is necessary to carefully ensure that the side of the sheet, which is located closer to the end of the pipe, is perpendicular to its central axis. Next, using the marking material, a series of dotted lines is applied, and after the marking is completed along the entire circumference, the template can be removed.

If you have to cut a profile pipe, then it is advisable to make a special template from the same pipe, but with a larger section. In this case, you will have to use measuring devices only once. For marking, you will need to use a protractor or a construction square. After sawing off the template, the pipes to be cut can simply be inserted into it and marked. This approach will significantly save work time and cut profile pipe at 45 degrees will be convenient.

As for what to use when carrying out work, here it is worth choosing the most suitable and familiar one. It can be both simple and a grinder with a cutting disc installed.

90 degree cutting

When it becomes necessary to cut at 90 degrees, the situation is even simpler. In the case of cylindrical elements, the same sheet of paper with which the pipe is wrapped can be used as a template. It is important to ensure that the edge of the sheet is even and coincides around the entire circumference. After marking, the cut element is fixed and the cut is made.

The video shows the process of cutting a pipe at 90 degrees.

How to cut a profile pipe straight

You can cut a profile pipe in much the same way, but here it will be easier to use a square. The device is alternately applied to each side, for which the cut element will need to be rotated, and markings are applied. Next, the pipe must be fixed motionlessly and you can start work.

Any suitable tool can be used for sawing. If you have to cut pipes a lot, then it is advisable to make full-fledged templates from scraps. In this case, measuring and marking work will have to be done only once.

Cutting large diameter pipes

When it is necessary to cut a large diameter pipe, a number of special devices and tools can be used. This may be required if, for example, a pipeline needs to be repaired.

Bulgarian. The use of a grinder is justified in terms of the availability of the tool and the relative cheapness of the work. However, in this case, you should not count on greater productivity, in addition, carrying out work in this way is associated with considerable risk.
Roller machine. Such devices are also often called pipe cutters. In fact, such a device is the same angle grinder, but more adapted for this type of work. The machine includes a special frame, where the element to be cut is fixed, as well as a holder with installed cutting rollers, which perform direct work. It is important to understand that each machine must be purchased for specific tasks, that is, for the size of the pipes.
Gas cutting. This option is most often used when working with large diameters. The cutting is carried out by means of a high-intensity flame, and the resulting waste is blown out by the pressure of the gas. The method can be considered the most practical and effective.

There are other options for carrying out the task, such as the use of plasma, waterjet or laser cutting, but in private use they are practically not used.

How to cut a cast iron pipe

If the pipe is made of cast iron, then in order to cut it evenly, you will have to apply certain knowledge. The fact is that this material is characterized by high fragility, which means that before cutting off such a pipe, it is necessary to determine the algorithm of actions.

We mark it in the same way as steel pipes.
In the place of the cut, you need to put a wooden beam as a support.
Next, you need to cut a few millimeters around the entire circumference.
After that, a chisel is inserted into the groove and a sharp and swipe hammer.

As a result, it will split along the line, forming a fairly even cut point, which, if necessary, can be further processed.

How to cut along

Another frequently asked question is how to cut the pipe evenly with a grinder along. Here the algorithm of actions will be approximately the same as for transverse cutting. It is important to pay attention to marking. You can, for example, use paint thread, which is usually used when marking walls. In this case, it is necessary to firmly fix the pipe. The sawing process itself must be done carefully and slowly, since when sawing long elements, there is a high probability of slipping cutting disc from the marking line.

How to cut thin wall pipes

Another type of pipes are thin-walled products. They are usually made from non-ferrous metals such as aluminum or copper. cutting thin-walled pipes is characterized by greater complexity, since the probability of deformation of the element is high. In this case, you can use some kind of filler, such as sifted sand. As a tool, you can use a grinder, a hacksaw for metal or a special machine. It all depends on the specific situation.

Cutting metal pipes is a rather time-consuming, but do-it-yourself process. At the same time, work with round pipes does not fundamentally differ from cutting a profile pipe. The main thing to remember is that when performing work, you must follow the safety rules.

During various works, home craftsmen are sometimes faced with the need to mark and cut pipes at forty-five degrees.

There are a large number of industrial production devices for cutting pipes at different angles, but the cost of such devices is quite high. The article will consider ways to mark pipes for a 45-degree cut at home, without the use of expensive fixtures.

Marking and cutting profile pipes

Marking a profile pipe at first glance seems to be a fairly simple matter. However, rounded corners with manual marking will give a serious error. For this reason, it will be more convenient to make the simplest device for marking a profile pipe. Cutting metal pipe at 45° With the use of this device, it becomes much easier.

45 degree pipe cutter is a piece of U-shaped steel profile, cut at an angle of 45 degrees. The dimensions of the profile are selected in such a way that the pipe to be marked fits freely into it. To make this device, you will need the following tools:

goniometer;
Scriber for metal;
Angle grinder (Bulgarian);
cutting disc;
File.

Such a device for cutting pipes is made quite simply. It is convenient to use for cutting a large number pipes, for example for frame welding.

A blank about 20-30 centimeters long is cut out of the profile. Using a goniometer, an angle of 45 degrees is marked at one of the ends of the segment. After marking, with the help of a grinder, the profile is cut. On the resulting template, it is necessary to check the accuracy of the angle. If necessary, the template is finalized with a file.

Cutting a pipe at forty-five degrees using such a template is greatly simplified. The pipe blank is inserted into the template and marked with a scriber. When marking, it is necessary to control the length of the workpiece. After that, the pipe is cut according to the marked marks with the help of a grinder.

The pipe is cut along diagonal lines on both sides, after which straight marking lines are cut. This pipe miter cutter saves time and money.

Marking and cutting pipes at an angle of circular cross section

When it is necessary to cut a round pipe at an angle of 45 degrees, the fixture discussed above may not be suitable. Cutting the pipe at 45 degrees in this case is done according to paper patterns wrapped around the workpiece. The template for marking can be downloaded.

Such patterns are printed from special computer programs. Also on the Internet you can find and print ready-made patterns for the most common pipe sizes. Whatever method of pipe cutting is chosen, it is necessary to monitor the accuracy of marking. This affects the accuracy of the cut.

How to cut a profile pipe at an angle

Now in hardware stores you can find special tools for cutting pipes. But it is easier and cheaper to make a template yourself.

When carrying out work on the installation of gas or water mains, it often becomes necessary to change the direction of the line, while the pipeline is cut off and then welded at the desired angle. Most often, the direction changes by 90 degrees, and the question arises - how to cut the pipe at 45 degrees in order to accurately connect the joints when welding.

You can cope with the problem at 45 or 90 degree angles of the cut edge with the appropriate knowledge and techniques that will help save not only time, but also materials during the work. At other angles of turn, it is impossible to solve the problem with the help of a ruler and a sheet of paper - you will have to call computer equipment for help.

Fig. 1 How to cut a pipe at an angle of 45 degrees

45 degree cutting

Usually, in order to rotate the pipe by 45 degrees, fittings are used, bends with a rotation angle of 45 degrees, made of the same material as the pipes themselves, if the pipes are steel, then the turns are welded from steel. For HDPE pipes, there are electric-welded or cast bends at 45 degrees (note that compression fittings with such an angle of rotation in Russia is almost impossible to find).

But, if you still need to cut a round pipe made of steel or different kind plastics, then for this you need a template for cutting pipes at an angle, the shape of which is calculated manually or by machine. The task is greatly simplified if at an angle of forty-five degrees it is necessary to cut off a square metal profile.

For cutting to hastily you can use a regular sheet of paper folded diagonally, with which you mark the surface for the future cut. Using folded paper, proceed as follows:

carried out on a straight surface of the profile in the place where the cut is performed, strictly perpendicular to the line;
apply a diagonally folded sheet of paper to the side surface with a sharp end to the line so that the upper edge of the paper triangle is flush with the upper side of the metal profile.

Rice. 2 Homemade template for cutting a pipe at 45 degrees

draw a line with a pencil along the side of the sheet at an angle of 45 degrees, after which the paper corner is applied to the other side and circle it with a pencil (it is better to use a thin marker).

For sawing, you can use a grinder with a disc for metal, drawing a thin line along the marking at the beginning, and then gradually deepening it until the edges are completely separated.

When working with an angle grinder, the following factor must be taken into account - when the edges are completely cut, the disk can be damaged by an acute angle, which will lead to its failure, and in the absence of protection on the angle grinder, even to injury to the worker. Therefore, it is advisable not to cut the corner edges to the end, but to leave a narrow groove and then break off, subsequently grinding the protrusion.

Making a template for trimming a metal profile

If you need to cut a large number of pipes, you can make a template from a metal profile of a larger diameter on a paper sheet using the above method. The angle of inclination is checked with a protractor or a construction square - in this case, the two edges of the trimmed parts of the template are connected.

When working on the part to be cut, a template is put on in the right place and pressed tightly, the marking is applied with a sharply sharpened scriber when tracing the template contour. The part is cut in several passes with a gradual deepening of the groove.

Rice. 3 Cutting a metal profile with a miter box

DIY pipe cutting miter box

Using a template is not very convenient - you have to make a cut along the line, holding the grinder on weight, which leads to large errors. In the presence of welding machine you can make a simple miter box - grinder guides for the disk, preventing it from going to the side.

To do this, use the previously made template, in the side of which a hole is drilled and a nut is welded. When working, a home-made miter box is put on the profile, a bolt is screwed into its nut and the device is pressed against the profile surface. A grinder with a disk for metal cuts, slightly pressing the disk against the side surface of the device. It is clear that during prolonged work, the edges in the miter box gradually grind off, and although the process occurs simultaneously on all edges, some errors will appear over time. Therefore, the device is better to be made of hard wear-resistant metal in order to increase its service life and get a more accurate tool.

Instruction

Prepare an angle template that will help you easily make an accurate cut of a piece of wood at an angle of 45 degrees. This device is a profile in the form of an inverted letter "P"; on its sides through slots for a hacksaw are made. Usually they are located at angles of 45, 60 and 90 degrees. More complex miter boxes are additionally equipped with arbitrary fixed slots, or they have a swivel design - it allows you to set the saw in the optimal position.

Buy ready-made carpentry tools from a hardware store with a wood, metal, or plastic tray. For a beginner, this best option. If desired, you can make a simple miter box from three planed boards or plywood strips (thickness - about 1.5-2 cm).

Drill several holes in the walls of the future miter box, apply wood glue to the ends and assemble the box (tray) of the miter box. Fix the corner template with screws. The walls of the tool must lie strictly parallel to one another; the bottom and each sidewall make up clear perpendiculars.

Mark a 45 degree angle with a pencil, add additional groove lines if necessary. In order not to be mistaken in your calculations, use a protractor.

The most important thing is the cuts. It is recommended to perform them with the same hacksaw, which will subsequently be cut in the finished miter box. Start sawing without strong pressure on the working tool, hold its blade. First cut through one sidewall, then the opposite.

Start processing lumber. Secure the miter box to a workbench or desktop with a clamp (clamps for fixing parts) or screws. Then make a mark for the future cut on the rail (board, plinth) and put the workpiece in the box. Press it firmly against one of the side walls of the template, aligning the marks with the 45-degree angle slot.

Insert a hacksaw into the grooves of the miter box and cut the workpiece. The work of the saw will be limited to fixed cuts and you will get a smooth and precise cut.

When sawing skirting boards, make sure that the corners in the room are really straight. If the walls are very uneven, the angle of cut on the workpieces should be corrected. Measure the joints with a goniometer internal walls and divide the result in half (the joint of the plinths "in the moustache"). To make an accurate cut, it is recommended to make grooves with a given angle in a homemade miter box. Another option is a magazine rotary tool that allows you to change the angle from 0 to 180 degrees in increments of about 15 degrees.

This tool is a profile in the form of an inverted letter P. On the sides there are slots in it for sawing at an angle of 45, 60 and 90 degrees. More complex corner templates or miter boxes have fixtures for exposure various angles sawing.

For the inexperienced master the best option will be the purchase of a finished miter box in a hardware store. At home, it can be made from three planed boards or plywood.

The tool can be assembled by fastening together pre-prepared parts. The corner template box must be secured with wood glue or screws. The side walls of the miter box must be strictly parallel to one another. The horizontal bar must create a strict perpendicular with the side ones.

Step 3: Mark cuts at different angles for sawing laminate, architraves, etc.

The application of slots will affect the accuracy of the work performed in the future. Therefore, this process must be approached with particular diligence. It is desirable to make cuts using the same hacksaw with which the work will be performed.

Step 4: Preparing the material to be cut at a 45 degree angle

It is necessary to fix the finished corner template on the desktop with a clamp. Next, mark the future cut on the workpiece. Next, you need to combine the workpiece with a 45-degree slot inside the miter box and press firmly.

The hacksaw must be inserted into the corresponding grooves of the corner template and the workpiece must be cut. The grooves will limit the movement of the saw and the cut will be carried out in the right direction.

The subtleties of working with a miter box and various materials

When sawing elements such as baseboards, it is not always worth making a 90-degree cut. After all, the walls in the room can be uneven. Before sawing the skirting board, it is necessary to correct the cutting angle.

Thus, the article described and characterized the process of sawing wooden materials with the help of a chair.

In various situations, masters of the household level often come to the question correct markup for precise cutting of tubular blanks at an angle of 45 degrees. Today there is huge selection tools, both for household and industrial process of cutting pipes at any angle. The cost of such devices is quite high.

How to cut a pipe at an angle

It is proposed to consider methods for marking workpieces for cutting at an angle of 45 degrees at home without the use of professional expensive equipment.

Pipe marking and cutting

Pipe Miter Tool

The process of marking the trimmed workpiece itself seems to be a fairly simple matter. But it should be noted that the rounding allowed in the manual marking process will create an irreparable error after cutting, which will lead to inconsistencies and the formation of defective products. In order to eliminate such defects, it is required to make a simple tool for clearly marking profile parts. At the same time, cutting products at an angle of 450 is greatly simplified.
A regular U-shaped steel profile cut at a 45 degree angle will be a reliable tool for precise pipe cutting. At the same time, the size of the profile for the ruler must be selected so that it becomes possible to easily locate the cut profile pipe in it.

To perform such a tool marking the correct angle, you must also have the following additional tool:

goniometer;
Scriber for metal;
Bulgarian;
cutting disc;
File.

How to cut pipe at an angle

Making a measuring tool for cutting pipes is easy. To do this, it is necessary to cut a segment 20-30 cm long from a profile blank. Using a protractor, at any end of the segment, mark an angle of 45 degrees. Next, cut off the profile with a grinder. The resulting pattern needs to be tested for accuracy. In case of deviations, file the measuring device with a file.

Using such a marking tool made with my own hands, the process is greatly simplified, especially with a large volume. To mark, it is only necessary to place the cut profile pipe in the device made, draw the correct angle using the scriber. In the marking process, the length of the products is controlled. Next, you need to cut the pipe clearly along the marking lines using a grinder. It is worth noting that at first the pipe is cut along diagonal marks on both sides, then straight marked lines are cut. These templates for cutting pipes at an angle of 45 degrees will save a lot of time and money.

In case of cutting round pipes at a 45 degree angle, a tool made for rectangular pipes is not quite suitable. For more accurate - streamlined drawing of the cutting line at an angle, it is recommended to use a paper pattern that is wound around the workpiece.

Patterns are developed in modern world using computer programs.

The cutting line changes depending on the angle and diameter of the pipe specified in the program. Common patterns can be found on the Internet or remember our painted rulers from school.
