What can be done from a circular disk
Kitchen knife from a circular disc
Greetings to those who like to tinker with it, I propose to consider a high-quality kitchen knife, which any chef will be happy with. The starting material for the knife was a circular saw blade. The blade was hardened, the blade was sharpened so hard that the knife easily cuts the paper. The manufacturing process is not complicated, but you have a lot of sanding work to do, so having a belt sander will be helpful. If you are interested in the project, I suggest studying it in more detail.!
Materials and tools used by the author:
List of materials:
– saw blade (better than the old model);
– wood for the handle;
– brass, textolite or G10 for bolster;
– brass rod for the pin;
– epoxy adhesive;
– pickling acid;
– heat-resistant cement.
Knife making process:
Step one. Cut out the main profile
First you need to pick up high-quality source material. The author used a saw blade for such purposes. Before making a knife, it is important to check the steel for hardening, as in modern discs, the steel can be bad, and the knife will turn out to be unsuccessful. Well, then draw with a marker on the disc the desired profile of the knife and cut it out. For cutting, the author used an ordinary grinder.
Step three. Bevels
We proceed to the formation of bevels on the knife, but for this we first make the markings. It is important for us to draw a line along the blade, which after grinding will be directly the blade itself. It can be carried out with a special device, or using a drill of the same diameter as the thickness of the workpiece. And so that the line is clearly visible, paint over the metal with a marker.
Then you can start grinding, in this case we need a belt sander. The author holds the workpiece with his hands, and so that the steel does not overheat, we wet the blade in water from time to time. When working, make sure that the bevels are symmetrical. The blade after work must have a thickness of at least 2 mm, otherwise the steel will burn out during hardening.

Step four. Heat treatment
We start hardening, the author decided on the jamon line on the blade, with it the blade looks unique. To obtain such a line, we need heat-resistant cement, we coat the upper part of the knife with it. Where this coating will be, there the steel will then differ in color.
That’s all, now we heat the blade to a red glow and dip it into the oil. To avoid unpleasant surprises such as cracks and deformations, the oil must first be heated. After hardening, we check the blade with a file, there should be no scratches.
After hardening, we must make the tempering of steel to give it spring properties. As a result, the blade will be able to withstand high bending loads, it will also break if thrown onto concrete. We release the blade in the oven, the temperature should be around 200 ° C. As for the time, it is usually about 2 hours, you need to make sure that the blade is covered with a straw-colored bloom, this will talk about the release of steel.
Step five. Etching
To get the jamon line, we need to pickle the steel. To begin with, polish the blade very carefully to a shine. The steel must also be well degreased, otherwise the reagent will not react with the steel. We lower the blade for a while in acid and watch the process, waiting for the desired result.
After etching, we treat the blade with soda or another reagent to neutralize the acid. Then the knife is washed under running water and now we have a wonderful blade ready.
Step six. Blank for handle
To make a handle, we need a piece of beautiful wood, as well as G10 material or sheet brass, if desired, for making a bolster. To begin with, we make a bolster, cut off a piece of the desired size and make a slotted hole for the knife shank. If there is no router, you can work with a drill and flat files.
Also, a slotted hole must be drilled in the bar, from which the handle will then be made. You can drill a number of holes and then combine them. That’s all, now we glue all these parts on the knife shank. We use epoxy resin as glue. The steel must be well degreased for good adhesion. We clamp the whole thing with a clamp and leave it to dry.
Step seven. We shape the handle
When the glue is completely dry, you can now set the desired profile for the handle. We cut off the excess on a band cutting machine or a hand jigsaw. Next, we modify the handle with wood files and sandpaper. The wood must be brought to a perfectly smooth state, so the handle will be pleasant to the touch, and you will also get an expressive wood pattern.
When the handle is ready, saturate it with wood oil or wax. Such an impregnation will perfectly protect the wood from moisture, which is important for a kitchen knife. And also the oil emphasizes the natural beauty of wood.
Step eight. Completion
That’s all, the knife is ready, it remains to sharpen it. For such purposes, it is very convenient to use sharpening stones or a manual machine based on sharpening stones. The author has sharpened the knife to the state of the blade, he easily cuts the paper. Of course, such a knife will cut perfectly greens and other products.
In general, if the knife is not left to sour in the sink, it will last quite a long time. At this point, the project can be considered successfully completed, I hope you liked it. Good luck and creative inspiration if you decide to do this again. Do not forget to share your ideas and homemade products with us!
Frame for a mirror or photograph
It will take a lot of discs, scissors, paints, glue, thick cardboard, colorless transparent varnish.
First you need to cut a frame out of cardboard in the shape and size of a mirror or photo. Then cut the discs into pieces of different shapes. squares, irregular quadrangles, rhombuses, triangles.
Take glue and stick it on the frame of the figure so that there is a distance of one or two millimeters between them. As a result, you will get a mosaic of iridescent geometric shapes on the frame.
When the glue dries, and the figures cut from the disk stick well, use black ink or paint to carefully and carefully go through the joints of the figures. After that, the frame is covered with transparent varnish, allowed to dry and attached to the wall with a mirror or photograph.
Mirrored frames made of discs look mysterious and original.
If the apartment has interior doors with glass, glass can also be laid out with a mosaic of disks. In this case, the joints between the pieces do not need to be painted, but simply cover everything with transparent varnish, then there will be a feeling of light and space.
Crafts from disks. how to make them yourself? 110 photos of ready-made ideas!
The time of CDs has almost passed, many still have a large number of them. music, with films, cartoons, with outdated computer programs. with images of heroes of fairy tales and films, flowers, graphic pictures.
They sparkle and shimmer with all the colors of the rainbow on the one hand, on the other. they have beautiful drawings. The hand does not rise to throw them away. and it is not necessary, from them you can make a lot of original, beautiful and useful things for the home.
In addition, it is very simple to work with them. they already have the correct circle shape, which in some crafts will only need to be slightly changed in order to give the future product or decoration the desired look. At the same time, they are easily cut with ordinary office scissors and are glued to the surface of almost any material.
It happens that some home interior items have lost their appearance, there is no way to replace them with new ones, or it is simply a pity to throw away an old favorite thing that has served faithfully for many years. Discs help give things new life.
For example, they can decorate an old mirror, making an original frame from pieces of different shapes and sizes, sparkling and shimmering in the rays of sunlight from a window or in the light of an electric lamp with all the colors of the rainbow.
You can make a beautiful frame for a photo, decorate the edges of the drawers of the cabinet with a mosaic of pieces of disks.
How to decorate a suburban area with disks
Creativity and imagination. space. For example, you can make a flower bed out of old car tires and wheels by decorating the outer surface of the tires with a mosaic of shiny pieces.
Or you can cut a peacock out of a rubber tire, and make the tail from whole round discs. for this they need to be glued in pairs with shiny sides outward, and then make them a large triangle-tail, gluing the glued blanks in pairs with an overlap.
On a country fence made of discs, you can depict a huge iridescent caterpillar. You can paint the discs under the ladybug. red paint, make black spots and draw a head, and plant them on fruit bushes and trees.
Household items from disks
The disks will make an excellent hot stand. In this case, the disc will play the role of a base, you need to pull a nice cover made of fabric onto it, and the stand is ready.
It will be original to update the coffee table top with cut pieces of discs. To do this, cut them, fix them on the countertop with a plasticizer in random order or make a pattern from pieces, and then pour a thin layer of transparent varnish on the countertop, making it even.
The coating will be durable. The table top will sparkle and shimmer beautifully.
Two discs and a thick tree branch can be used to make a holder for women’s earrings.
The core of the rack is made of a smoothly processed branch, turned along the diameter of the hole in the center of the discs, one disc will be the base, the second shelf, in it. make holes and insert the earring arches into them.
Clock from discs
An option is to purchase a clock mechanism with hands or take it out of an old clock, lay a clock of any configuration on the wall with disks, stick them in the wall, and strengthen the clock mechanism in the middle.
Wall decoration with discs
On the wall in the room or in the kitchen, you can put an interesting composition out of disks with beautiful pictures, selected by theme. Or you can use them to create your own picture.
To do this, you need to take the disks and paint their shiny side with black ink, when the ink dries, outline the lines of the future image along it, and then go through them with something sharp. a thick needle, a special scraper or a sharp knife with a thin blade and a sharp tip.
Iridescent lines on a black background will look very beautiful. you can draw anything: unusual birds, flowers, abstract drawing. And hang the disks on the wall in no particular order.
Decorating the kitchen with discs
In the kitchen, the disks can turn out to be an unusual “apron” in the desktop area. It will look extremely original, and in terms of working properties, the disks are not inferior to tiles. they are just as easy to wash from splashes of fat and juice of vegetables and fruits.
The principle of working with them is the same as with frames for mirrors and photographs. just stick on the wall.
Whether for a room or a kitchen. you can make a mosaic panel from discs by sticking pieces of the desired shape and color onto cardboard, and then covering the composition with transparent varnish.
Christmas decorations from disks
Due to the fact that the discs in the rays of light shimmer with all the colors of the rainbow, beautiful snowflakes will come out of them for the New Year’s holiday. they are easily cut with scissors, you can cut the most intricate pattern. You can hang snowflakes both on the tree and on the walls.
You can cut discs into small pieces, thickly paste over a regular ball with them and hang it from the ceiling on a thread. it will rotate and sparkle, reflecting the lights of New Year’s garlands.
The application can be very different. From the disks, you can make an interior curtain in the likeness of a bamboo. to collect disks on long threads. They can make an ultramodern necklace, a fridge magnet, a vase, a candlestick, a stand for ballpoint pens and pencils, a box, you can even decorate a summer bag with them.
Unnecessary CDs are an excellent material for creativity, a means of spending leisure time. making certain little things out of them, and the opportunity to decorate a house or dacha in an original and unusual way, without spending a lot of money.
Which discs should be used for circular
The performance and quality of work to a large extent depends on a properly selected disc for a do-it-yourself circular from a grinder, a hand saw or assembled from separate mechanisms. It should be remembered that discs are different for wood and metal. Even if thin, soft aluminum is to be cut, the blade must be fitted appropriately. Cutting wheels have smaller teeth. There are universal disc options that are applicable to work with both wood and metal.
There are differences and discs designed for longitudinal and cross-cutting wood. Rip sawing is carried out with a cutting attachment with large sparse teeth. But transverse cutting will be of better quality in the case of using discs with fine, frequent teeth.
As for the material and method of manufacturing discs, they can be monolithic and carbide. Monolithic are made from a single piece of high-carbon steel. Such nozzles are inexpensive, but at the same time they have a significant drawback: they quickly become dull and need sharpening and wiring.
Circular discs can be for wood and metal
Tungsten carbide wheels are made from cobalt and tungsten soldered tool steel. They are more durable, but the price for such products is much higher.
Parallel stop for circular do-it-yourself
A parallel stop is a mandatory device on a circular table; without it, it is almost impossible to make an even cut. You can make it yourself as follows:
- A U-shaped profile should be made of three strips of laminated chipboard, inserts must be placed and fixed inside, which will give rigidity. As a result, you get a square section.
- A guide channel is made of two parallel rails, which is bolted to the end of the table in a position perpendicular to the saw blade.
- Then an inverted T-shaped structure is made from MDF, which is screwed to the stop and inserted into the channel.

Parallel stop for circular can be made independently
Important! The width of the channel should be such that the side of the T-shaped element fits snugly into it.
To fix the stop with a self-made homemade circular, it is convenient to use original slots. Threaded bolts, nuts and wooden washers are suitable as a locking mechanism; you will need a hole in the lower plane of the stop. Tightening the bolt helps to securely press the stop against the table top. This design allows you to quickly and easily set the required cut sizes.
Making a carriage for a circular do-it-yourself
The functionality and high-quality work of a stationary circular is largely influenced by the availability of devices. One of these is the carriage. It is completely easy to do it at home, but the implementation of facing and sawing off material at an angle of 45 ° will be much easier.
You can make this device for circulars from a sheet of plywood as follows:
- plywood is cut out a bit wider than the circular table;
The carriage for the circular can be made with your own hands
- in the lower part, guide bars are attached to it with glue or screws, the distance between which should be equal to the width of the table;
- from above in a similar way, using screws or glue, stop bars are fixed.
With the help of guides, the carriage is fed along the table onto the saw blade, which makes a through cut on the device. The height of the sides, which should be larger than the protruding saw blade, allows you to maintain the integrity and rigidity of the carriage. If the task is to cut at an angle of 45 °, it is necessary to use an additional bar, which in this device is a removable element. Cutting is done by pressing the workpiece against an angled bar.
In order for the plywood surface of the carriage to be easily cleaned of sawing waste, it must be varnished in several layers.
The plywood should be slightly wider than the circular table
How to make a do-it-yourself circular shaft
In the general design of the circular shaft, the shaft is the main element that forms the whole machine. To make it, you will need steel round timber of grade 45. But you can only make this important part yourself only if you have your own lathe available or you can access it. The diameter of the workpiece must correspond to the dimensions of the saw blades to be used.
The main standard sizes of the bore of the discs:
- 16 mm;
- 20 mm;
- 22 mm;
- 30 m;
- 32 mm;
- 50 mm.
From the above indicators, the size of the shaft for the circular is selected.
For the manufacture of the shaft, you will need steel round timber of grade 45
The most common hole diameter is 32 mm. It is such a seat that the discs with different sizes of the outer diameter have. Alternatively, you can make a thinner shaft to be able to perform “jewelry” work. Then an adapter will be used to use large discs. In this way, it is worth complicating the design of a home circular only in those cases when it will be used by a professional.
Saw blades are installed between two flanges and pressed with a nut, which is screwed onto the thread made on the edge of the working surface of the shaft.
Important! The thread must be left-handed. During the inevitable jerk when starting the circular, the nut in this position will tighten, and not vice versa.
Bearing seats are determined taking into account the dimensions of the latter. The middle part of the shaft has the largest diameter. If the indicator is significant, an additional load on the belt will be created during rotation. To get rid of the problem, reaming will help, which will lighten the heavy part of the shaft.
The diameter of the workpiece must match the dimensions of the saw blades
Manual circular as the basis of a homemade design
One of the most popular tools on the basis of which homemade saw designs are created at home is a circular saw (hand circular). This electromechanical mechanism makes straight cuts in wood materials as well as in soft and thin metal using a circular disc. The tool is quite simple, it has all the basic elements available that allow you to make a circular saw out of a circular saw with your own hands.
The circular saw consists of the following parts:
- electric motor;
- one or two handles;
- protective casing;
Hand circulars make straight cuts in wood materials, as well as in soft and thin metal
- holding platform (for the possibility of exposing the disc);
- riving knife (prevents the saw blade from getting stuck in the wood).
Hand circulars stand out among other similar tools and some technical features. For example, the depth and angle of the cut can be changed directly in the course of work. Plunge-cut saws provide special opportunities. They can be used to make isolated fragment cuts of the required size.
Accuracy and quality of circular sawing depends on the number of teeth on the disc and on their sharpening angle. With a large number of teeth, the quality is higher, but productivity is slightly reduced.
When making a circular with your own hands from a hand-held circular saw, you need to pay special attention to the engine power. This is very important when intending to carry out significant amounts of work. The total weight of the saw is also important. Lightweight models suitable for occasional cuts.
The depth and angle of the cut can be changed directly during the operation of the circular
Determining the parameters of a do-it-yourself circular at home
The primary task is to choose the capacity of the future stationary circular. Usually, devices with a power of up to 850 watts are recommended for home use. If it is not supposed to carry out repair work, but to build, for example, a bath or a summer house, as a result of which it will be necessary to saw a lot of material, then a 1250 W motor can be used. A device with a higher indicator is not recommended, since such powerful circulars require not only a solid table stand, but also fixing the latter to the floor by fixing or concreting.
The cutting depth is an important characteristic. In home devices, it should not exceed 8 cm.In fact, this figure is quite enough for sawing boards, plywood or wood-based panels.
When making do-it-yourself mini circulars or a full-scale sawing structure, be sure to take into account the speed. If it is supposed to simply cut boards for the manufacture of certain wooden elements, then you can limit yourself to a motor with a low or medium frequency. If you need perfectly straight and clean cuts, then it is better to use a high-speed motor. The optimal indicator for a household power tool is considered to be a frequency of 4500 rpm.
For circular, you can use the engine from the washing machine
Be sure to take into account the height at which the trigger button will be located. The place of its placement should be convenient for pressing.
Important! The control panel of a homemade circular saw must be accessible.
Structural elements of a DIY wood sawing machine
To make a stationary machine for sawing materials at home, you first need to know what structural elements it consists of. Whether it is a do-it-yourself machine from a manual circular, a grinder, or a tool assembled from disparate elements, the set of basic parts is the same.
The surface of the table must be made even, for a better product at the exit
The main elements of stationary circular installations are:
- Table for connecting and fixing mechanisms. If the circular is powerful and massive, it is better to use a metal table. Options from chipboard, wood, plywood are suitable, as long as the surface is smooth.
- Shaft. The most important detail. When making it, they use a lathe separately. The dimensions should be calculated accurately, this will avoid beating.
- Casing. This element ensures safe use of the circular saw.
- Engine. When using a grinder or circular saw, it is part of the power tool.
Helpful advice! If the design is supposed to be prefabricated, then when creating a circular with your own hands, an engine from a washing machine will be the most successful option.
In the design of the circular, there must be moving parts of the drives, and a button must be installed in the power supply circuit to stop the engine in emergency situations.
Circulars of any fixed type consist of main parts
How to make a circular with your own hands: preparatory stages of work
Before you put an end to the question of the advisability of making your own circular, you need to personally get acquainted with several similar devices, watch videos on the Internet. During observations and views, special attention should be paid to the main elements, details, methods of fastening. To understand how to make a circular, you need at least theoretical knowledge.
The manufacturing process can be implemented in two ways:
- a set of elements of the future design is available, you only need to complete the assembly;
- the components of the circular must be purchased.
In the case of the latter option, the task becomes somewhat more complicated, since parts and mechanisms are most often bought in different places, but they must correspond in terms of technical and functional characteristics.
DIY circular making scheme
Helpful advice! It is necessary to acquire elements for the future design of the circular only after a detailed drawing of the installation has been developed.
Without a drawing, it is impossible to take into account the dimensions of the elements and select a complete set. Quite often, this stage (drawing work) is omitted by home craftsmen due to the lack of execution skill. This is not worth doing, since it is quite enough to draw a saw. At a minimum, this will make it possible to visualize the future unit. It is extremely important to imagine what will happen in the end.
Only after the drawing or sketch and all the necessary elements are available, you can proceed directly to the assembly process.
