How To Cut A Smooth 45 Degree Angle
Self-made miter box
- 1. First, you need to assemble the box of the future tool. To do this, it is necessary to drill holes in its side walls, for future fastening with screws and, having smeared the ends of the parts with glue, connect them in such a way that both walls are strictly perpendicular to the bottom and parallel to each other, after which we fix them with screws.
- 2. Using a protractor, mark an angle of 45 degrees with a pencil, if necessary, add additional mowing lines for the grooves. The most critical part is the cuts, it is best to make them with the same hacksaw blade as you will be cutting products. It is necessary to cut by holding the blade, avoiding strong pressure on the tool, first we cut one side, then the other.
- 3. We start processing the material. With a clamp or screws, we fix the miter box on the working surface. At the place of the future cut on the plinth or board, we make a mark. How to cut at an angle of 45 degrees becomes clear if you press it tightly against the side wall and align the mark with the slot on the template. We insert the hacksaw into the groove and cut the workpiece, while the work of the blade is limited to cuts, which allows you to cut as smoothly and accurately as possible.
- 4. Before sawing the skirting board, make sure that the corner of the room is really straight and, if it is not, you need to adjust the cutting angle of the workpiece. To do this, measure the inner corner of the junction of the walls, and divide the result by two. If you do not have a professional rotary miter box that can change the cutting angle by the required amount, then to achieve the result, you need to saw additional grooves at the desired angle in a homemade miter box. This way you can cut the skirting board for the most accurate alignment.
Now you know how you can cut a workpiece at a 45 degree angle. Perhaps the time has come to move from theory to practical action. The team of the mebeldok.com portal is sure that everything will definitely work out for you. stay with us!
How to use the miter box
A miter box will help you cut the plinth at a 45 degree angle. By the way, do you know how to use the miter box? The specialists of our portal have prepared for you a step-by-step.
How to cut at a 45 degree angle
Often, during repairs, you can face a situation when it is necessary to saw off a piece from a part, at an angle of strictly 45 degrees. Usually, this is needed to connect two parts at right angles, 90 degrees, such as: door trim, plinth, pieces of furniture and much more. An experienced craftsman, professionally engaged in repair work, can often do without special devices, and practically by eye is able to cut the necessary part evenly and clearly. But if you are a novice repairman, and you have a desire to do the work as efficiently as possible, without damaging expensive parts, then you just need to purchase a miter box. a special device that allows you to saw off material at a given angle without any special tricks.
To work, you need to have: a miter box, a hacksaw, a protractor with a pencil, a workpiece made of wood, a screwdriver with screws or a clamp.

How to cut the corners of a ceiling plinth
This is an instruction manual on how to cut the corners of a ceiling plinth. Considered options for solutions, such as.
Pipe cutting at an angle of 45 and 90 degrees
If you need to cut the pipe at an angle of 45 degrees, which is more often required when laying water, heating pipes. Steel, cast iron pipes that are cylindrical in shape are often used. In installation work, rectangular or shaped pipes are used. However, the angle grinder must be properly cut to allow easy connection later. Therefore, you should carefully mark the pipe.
Some craftsmen try to mark the place of the cut using a tape measure, but we warn you that the result is likely to be negative. And for a positive result, consider the following professional recommendation.
Take a sheet of paper or cardboard, preferably A4, fold it diagonally and wrap it around the pipe where you plan to cut it evenly. The edges of the paper must be in perfect alignment with each other. And the side of the paper that is closer to the end of the pipe was perpendicular to the axis. Then mark the cut line in a circle.
If you need to cut exactly at an angle of 90 degrees, then solve the problem quickly using paper or masking tape again. Wrap around the pipe so the ends match. Make even lines and saw off.
How to cut a profile pipe straight?
Masters advise using a square when cutting a profile pipe. To do this, apply the square in turn to the sides, and turn and mark with smooth movements. After action, fix the pipe and cut. Prepare yourself a template that will come in handy in the future and save time. It is better to produce an angle grinder, so the cut will be smoother.
How to cut a cast iron pipe?
When working with a cast iron pipe, keep in mind that it is a brittle material. Therefore, we will point out a way with which it will be possible to cut such a metal without damage.
Before starting work, make notes for the cut as you would for steel pipes. Place a piece of wood for support. Run an angle grinder around the circumference of the pipe making small cuts. Then take the chisels, insert them into the groove and hit hard with a hammer. Be aware that bakelite-based cutting discs are used to cut cast iron pipes.
If you do not have an angle grinder at hand to cut a cast-iron sewer pipe or other purposes, use a metal hacksaw, chisels or special pipe cutters.
How to cut a gas pipe?
Cutting a gas pipe is dangerous, so it is best to entrust it to professionals. But if you are confident in the strength, then take an angle grinder, welding, hacksaw, gas welding to cut the metal.
- Shut off the gas riser before work. Then release the rest of the gas from the pipe. To do this, set fire to the gas in the burners and wait for it to go out.
- After the steps taken, cut. Using the welding method, the metal base burns out when exposed to high temperature. The result is fast and effective. But remember that cutting or rooting gas pipes again takes experience.
How to cut a pipe straight angle grinder?
When dealing with construction or plumbing tasks, you need to know how to cut the pipe straight from an angle grinder. In the article, we will consider quick and easy ways of how to properly cut an angle grinder pipe so that the result is perfect.
Methods for cutting large diameter pipes
There are a number of reliable tools for cutting large diameter pipes such as sewers. Next, we will consider some of them in detail:
- An angle grinder is an inexpensive and affordable option, but it is considered not the safest when working with such materials. Once you decide to use this method, then be careful and use protective equipment.
- A roller machine (pipe cutter) is such a tool adapted for such manipulations. The device is attached and material removal begins. The clamping force is adjusted using mechanical devices. It is important to note that the models of the machine differ in shape, so consider the ratio of dimensions to the pipe before use.
- Flame cutting is the most popular option for cutting larger diameter pipes, sheet metal. The cut occurs due to the action of a high intensity flame, the metal melts and leaves the cut zone with a gas flow. This method is convenient and effective.
How to cut a pipe lengthwise correctly?
A quick way to cut a pipe lengthwise with an angle grinder:
- Focus on the markup.
- Use for such a case the painter’s thread, which has found distribution when marking walls.
- Before starting work, fix the pipe and with small movements, carefully saw the pipe.
- Better not to rush, but delicately and slowly process the parts of the pipe, so the cutting wheel does not jump off the marking lines. Remember safety.
How to cut thin-walled pipes?
Thin-walled pipes are made of non-ferrous metals: aluminum, copper. Such work should be done delicately, since there is a high probability of deformation of the material. Fillers such as sand are used for cutting. Actions can be carried out using an angle grinder, a special machine.
Summing up, we emphasize that cutting metal pipes is a complicated process, but anyone who wants to can enhance it. With the advice of professionals, you can easily handle cutting pipes in a variety of sizes and materials. Also remember to use a file or emery paper to clean the edges of the pipes after cutting. And the most important thing to remember when starting such actions is safety precautions. Wear a special suit (casing), mask or goggles when getting started. Hands should also be reliably protected from sparks, so use thick gloves.
Place the miter box on a workbench or on a surface to be filing. Then place the skirting board in the miter box. Bring the end of the skirting board to be trimmed to the slot of the miter box, which contains the required angle. Fix the skirting board firmly in the miter box to prevent it from moving. Insert a hacksaw into the slot and cut the plinth at the desired angle.
If not much trimming is required, then it is easier to saw down the plinth according to the markings applied. This is more time consuming, but also gives excellent accuracy. To do this: Using a pencil, a ruler and a protractor, mark a 45 degree angle on the plinth, for which first measure the width of the plinth and set aside the width of the plinth from the end along the length. After that, draw the line, combining the vertex of the corner with the deferred point. Use a hacksaw to cut the skirting board according to the markings.
The lowest accuracy is obtained by the method of filing the plinth “by eye”. It is allowed to use it only as a last resort. Proceed as follows: fix the skirting board on the work surface, sweep the angle of 45 degrees “by eye” and cut it with a hacksaw for cutting. Please note that in this option, the adjacent part of the skirting board will need to be filed in place, in accordance with the angle obtained “by eye”. All these methods are suitable for filing all kinds of skirting boards: wood, plastic, as well as for skirting boards made of foam.
The diagonal of a polygon is a line segment that connects two vertices of a figure that do not adjoin each other (i.e., non-adjacent vertices or that do not belong to the same side of the polygon). In a parallelogram, knowing the length of the diagonals and the length of the sides, it is allowed to calculate the angles between the diagonals.
Cutting with a miter box
What is a miter box? This is a special tray made of wood, aluminum or plastic with provided grooves to guide the saw at the desired angle.
Here is a quick guide to using such a carpentry tool:
- Training. We take the product and put it in the tray. Align in the position in which it will be installed on the ceiling.
- Cutting. With the other hand, insert the cutting tool into the groove. It can be a knife or a hacksaw. And we cut it boldly. The device will not let you miss the intended place.
45 degree tile cut
You should know: the blade for metal is also suitable for cutting foam.
- Treatment. Wooden skirting boards may need to be filed further to level the cut edges. Plastic or foam can be tweaked with a knife, the main thing is that it is sharp enough.
Tip: Do not press on the product when cutting. Styrofoam can crumble, and the tree can split altogether.
It’s so easy and simple to use the miter box
Features of cutting various angles
We have disassembled the general technology of how to cut off ceiling plinths.
How to cut ceiling skirting boards in the corners? The secret of a high-quality incision is in making cuts both on the outside and on the inside. The inner cut matters if we make the outer corner.
Usually they use professional equipment. miter saws or industrial electric rotary hammers. But home renovation advocates can get by with conventional tools. The main requirement is that at the end of the work, the result should be a clearly visible texture for the cornice, reflected on its front or back side.
The product is installed around the perimeter of a rectangular room. Trimmed to trim right angles. Therefore, we will consider how to cut a skirting board at 45 degrees.
External floor corner view
In this case, using the miter box, we are not a mode of internal, but external edges. The rest of the operation is similar.
How to make a miter box at home?
If the above methods are not to your liking, you can make a miter box at home yourself. A miter box is a device that resembles a tray in its shape, which has a U-shape.
It is equipped with saw slots for cutting material at a certain angle. The dimensions of the parts are not very important, but the wider our homemade device is, the wider and more accurate we can cut wide slats.
Everything needs to be done wisely, you should not overdo it either, because if the width of the miter box exceeds half the width of the hacksaw, it will be inconvenient to saw.
You can do the markup using the methods described above, then use small pieces of plywood and a hacksaw. And in order to hold everything together, you can use self-tapping screws or even super glue. However, all this is more complicated and will take much longer, although it will provide the most accurate result (of course, if you do everything right).
However, if for some reason a situation arises that it is impossible to get the tool in the shortest possible time, you can use improvised tools, such as a ruler, protractor or even tiles, with which it is easy to create a template with the necessary markings or even completely recreate a miter box at home.
Diligence Produces Results
If you still have any questions, then the visual in this article will help to resolve them.
By carefully following the recommendations and taking into account the peculiarities of the material with which you work, you can give your ceiling beauty and originality. Choose the method that you like and go ahead! You will succeed (read also about the advantages of PVC skirting boards).
How to connect with a door trim
You know neatly how to make a corner on a plinth, but that’s not all. The room most often has doors. By the way, they must be installed before fixing the baseboards. So, you still need to correctly dock the skirting boards with the platbands on the door. If you just cut it straight, it turns out rough. There are plugs for plastic. not the most elegant way, but quite acceptable. Wooden ones can also be trimmed by cutting off the “face” obliquely. Also “not ice”, but already something. And what to do with MDF skirting boards, because the saw cut from them is unpresentable? There is a way to make a beautiful junction with the jambs. You will need to make two cuts at an angle of 45 degrees (see photo below).
How to properly arrange the joint between the skirting board and the door jamb
If the edge is not even, we first cut it off strictly perpendicularly. With respect to the aligned edge, make a 45 degree cut. A small cut off piece will be useful for us to design the junction. We make the second cut at 90 degrees relative to the first, but if we lower the perpendicular from the angle, we also get 45 °.
How to make a neat jamb fit
Now we take the first cut piece, attach it to the just made cut with the long side. It turns out a beautiful rounded cut. If there are chamfers, grooves on the plinth, they match perfectly. In the case of woody patterns, you cannot be sure that the lines match. Anyway, such a joint between the skirting board and the door casing is much more aesthetically pleasing.
Platband is an overhead frame inherent in the opening of a door or window. This is a decorative piece made in the form of curly strips. There are also carved platbands, their difference is that they are made of wood and are often decorated with abundant carvings. The role of the frame is not only decorative, it allows you to slightly eliminate such unwanted blowing in the area of the gap between the wall and the window or door frame, by overlapping.
Ways to cut the platband at 45 degrees without using a miter box
The easiest way is to use an ordinary protractor, which is in every house where a school-age child lives. It is not so difficult to make markup with its help.
The cut itself is also important. To avoid the formation of cracks, it is recommended to use a hacksaw not for wood, but for metal. Yes, this method takes more time, but for that the cut will be much more accurate and smoother.
When the markings are made using the protractor, you need to position the platband on a horizontal surface so that the front side is up. It is recommended to make a cut along the entire plane of the casing.
If there are no stationery nearby, you can use a regular tile with which you can draw a 90-degree angle. By dividing it into 2 halves, we get a 45-degree angle template that can be used for marking in place of a miter box.
If there is a ruler, the task is simplified several times at once. You just need to take a leaflet A-4 and draw a square, then draw the bisectors of the corners. To make it more convenient, you can take a small board and attach it to one of the corners, which will allow you to fix the structure. Well, then you need to attach the platband and start sawing.
How to cut the skirting board in the inner corners: an action plan step by step
Begin installing the skirting boards in one of the corners. If this is your first experience, choose the part of the room where something will stand. Not always, it’s over, the first pancake is lumpy, but it’s still better to insure yourself. To make the corner on the baseboard neatly, work slowly. One was sawed off, checked, adjusted. Let’s move on to the next one. It is better to fasten after two adjacent corners are assembled. But you should not postpone the assembly too much.
Trimming skirting boards in corners requires some skill. But having made several joints yourself, you can beautifully design complex corners.
How to use a miter box to cut skirting boards? Place the device in front of you, preferably on a table, but also on the floor. It does not matter which side to turn it, it is symmetrical. Insert the bar into the profile, turn it so that it will stand against the wall. When washing down a floor plinth in a miter box, the “wall” is the wall that is farther from you. Once again: press the plinth strip firmly against the back wall in the position in which it will be installed. Insert a hacksaw into the desired slots. You can start sawing.
Trimming parts at an angle using a protractor
You can trim the part at an angle using a protractor. This is a measuring tool that is easy to use, and which is designed precisely to measure angles or make the necessary markings on certain parts. The protractor is applied to the part, the angle is marked and the markings are made with a pencil. Using this marking, it will not be difficult to cut the workpiece at the desired angle.
How and what to cut a plastic skirting board
All of the above applies to MDF and wood skirting boards. Cutting them with an ordinary hacksaw is not a problem. It is advisable to take a blade for metal, since it has a smaller tooth and the saw cut is smoother, you will have to work less with sandpaper. With plastic, the situation is different. when you try to cut a piece, some thin-walled skirting boards crumble and break.
Cutting plastic is not very convenient because of the thin walls
To cut normal quality plastic skirting boards you can use:
- Hacksaw for metal.
- angle grinder (angle grinder) with diamond disc.
- A revolving miter saw. Before cutting, speed up the disc and only then start cutting.
- A jigsaw and a file with a fine tooth. Here you have to try. select the speed and file.
- Sharp knife.
- Metal scissors. In any case, it is not difficult to make straight cuts with them.
Only personal experience will help you decide what is more convenient for you to cut a plastic floor plinth. If you have a miter saw, try using it. It is not a problem to try the angle grinder with a diamond disc a couple of times. If all this does not work well, try a hacksaw, jigsaw, or knife. There are, of course, special scissors for plastic, but they are too expensive to buy for a single use.
Accessories for the design of corners and joints of PVC skirting boards
In plastic skirting boards, you can design corners and joints using special fittings. There are external and internal corners, plugs and connectors. Basically, they allow you to assemble the desired configuration. Each manufacturer makes its own fittings. for its own profile, colors. But the principle of their use is the same.
How to shape the corners of a plastic skirting board
The first rule is that all cuts are made straight. Strictly perpendicular. The marks in the corners are set at a distance of 1-1.5 mm from the corner. The fact is that the rigidity fittings have their own jumpers. For them, it is necessary to retreat a couple of millimeters, but no more. Otherwise, a gap will appear or skirting boards will pop out of these corners.
This is the result of the assembly
Epic 45 degree tile cut. Perfect outer corners.
I must say that not everyone likes the look of plastic corners. You can make a corner on a PVC skirting board in the same way as described for wood or MDF. The only difficulty is that you have to be careful with plastic. it breaks down from excessive efforts. There is one trick. before cutting the plastic skirting board, add a little polyurethane foam on the back side and wait for the polymerization to begin. It will be tougher, easier to cut, less deformation. If the foam subsequently interferes, it is not a problem to remove it, but to cut it is, indeed, easier.
First joint in the room
The first plinth should be cut as close to the edge as possible. Carpenters have their own jargon and they say “cut” the corner. It does not matter what you call it, it is important that in the miter box we set the bar so as to make a cut at the very beginning. For the cutting line, we push the bar a short distance, for a start, you can 1-2 cm. Cutting a smaller piece is more difficult, so save the savings “for later” when at least some skill appears.
In the miter box, place the plinth at the far wall “facing” you. This makes it easier to check if you are cutting / sawing correctly.
Then you need to make a corner on the plinth like this:
- We put the plinth in the miter box, press it against the wall opposite us. We expose it in the mounting position. how it will stand against the wall.
- Insert the hacksaw into the desired slots (see the picture below).
- Move the bar so that it goes slightly beyond the cut line.
- Cut off.
- We take the second piece of plinth, repeat the same operations, but change the position of the saw on the miter box to the opposite. We insert the bar on the other side. Be careful here, otherwise you will have to redo it several times, since the connection will not work.
How to cut a floor plinth in a miter box correctly: for external and internal joint
We got two pieces cut for joining in the inner corner. To make the joint perfect, we try on the details in place. Most likely there are some flaws. We take sandpaper with medium grain, remove everything that interferes with docking. Then, with small grain, we achieve a tight joint without cracks and gaps.
When joining the skirting boards in the corner, use a transparent silicone sealant. Before installing the fasteners, a layer of silicone is applied to the cut. Immediately after the plinth is fixed, remove the excess that appeared outside. We clean up to an absolutely clean surface. This way of connecting the skirting boards in the corners looks more neat, dirt and dust does not clog into it.
Miter box for skirting boards
A carpenter’s miter box is a device for cutting at a certain angle. It is used with a hacksaw. In principle, you can make a miter box yourself by assembling a guide from the boards and making cuts in the walls. There are various models on sale ranging from 15 to several hundred dollars. They differ in capabilities, materials, although all are called “miter box”. Professional models are made on the basis of a good hacksaw, have a scale that allows you to set the saw as it should. With such a tool, it is not a problem to set any desired cutting angle in order to properly cut the skirting board for a perfect fit.
Professional carpentry miter box. a tool with a wide range
The simplest miter box is a plastic U-shaped profile, in the walls of which slots are formed. These slots are used as a hacksaw guide. They do not allow the web to deflect. In any case, there are two cuts. straight and at 45 degrees. Some may have a couple more options.
How to cut a plinth at 45 degrees? One way is to use a miter box
Sometimes a hacksaw is included, sometimes not. Usually the ones included are not very good. Any hacksaw can be used, picking up a blade for the material that is planned to be cut. It is important that the blade moves freely in the slots.
If there is no protractor, miter box or ready-made corner pieces available, you will have to look for a suitable template. Of course, the template must have the correct angle. It is applied to the workpiece and the workpiece is marked with a pencil. This is one of the easiest ways to achieve the desired result.
