Circular saw carriage with their own hands
Assembling the guides and carriages for your CNC machine with your own hands
Polished shafts are used most often and are inexpensive. Buying these elements is not difficult. They can be assembled and machined. Mostly made of solid steel.
The top layers are then subjected to induction hardening, which has a beneficial effect on the period of use and wear rate. Their perfect smoothness enables the carriage to run smoothly on the polished layer. You can use two hands to attach the shafts at either end without any problems.
But there are also many fake elements on the market that are made of low quality metal, because there is no chance of a precise on-site inspection.
- The base is not fixed. The shaft can only be supported on the basis of two fixing devices. This makes it easy to install them yourself, but they are independent of the table-top support. Because of this the possibility of defects during the processing of the product increases. Over time, lathe carriage guides roll off and warp.
- There is sagging at long intervals. Due to sagging, the shaft with a length of more than 100 cm is not used when machining for the machine. The thickness and length of the gross surface are also important. The best option is 0, 05, and even more advantageous 0.06. 0.1.
Homemade table saw
Manual circular saw. an indispensable tool in the home workshop of the self-respecting owner. For successful work it must have a guide rail for circular saw. Saw blades are of great importance, the quality and precision of the cut depends on their thickness and the size of the teeth. The smaller the tooth, the cleaner the surface that is machined.
A well-equipped workshop has a hand-held electric tool that has a circular saw guide rail, handmade and set up for successful work. As well as a special connection for a vacuum cleaner and bags or containers for sawdust. This is a very practical solution, because during long sawing you will not have to stop every minute to clean the workplace. This saw is made by Bosch for professionals. In addition, it has the ability to adjust the angle of deviation from the vertical and the depth of cut.
Choosing the right tool
Before buying, it is worth making sure that the tool you choose has the right depth of cut vertically and at an angle. An additional aspect that can facilitate normal work is the cable length. If conditions are not favorable for the use of an extension cord, a saw with a long cable should be chosen.
The saws offered by reputable manufacturers are equipped with a device for easy replacement of the discs, which further simplifies the work. It is an excellent electric tool, which can be used for small home and garden repairs.
For those people who like to make crafts, this mechanism is a must. Because of its small size, there is always room for it even in a small home repair shop.
What is a trimmer carriage for a circular mower and what is it for?
The carriage, or guide rail, is an auxiliary tool when working with the saw. It comes in different sizes and is required to cut wood pieces from small frames to large panels, such as furniture pieces. It provides the most accurate cutting, reducing the need for further adjustments to the product.
Such a useful accessory as a carriage for a circular saw, with their own hands to make sometimes easier than to buy a ready-made set. In this case, all dimensions can be precisely adjusted.
Characteristics of carriages
When buying or creating a homemade carriage, indicators are taken into account:
For the machine to last long and good quality, it is necessary to control:
- Length and width of cut.
- The direction and ease of movement of the tool.
- The density of the product used by the craftsman.
- Sequence of work, safety precautions.
- General purpose of the saw.

The common parallel stop for a circular saw is a good example of how a small addition can make a big difference. Nearly every portable circular saw is equipped with a parallel stop for making narrow cuts of a specific width. This is a really useful device.
The regular stop has one disadvantage. For safety purposes, it is set to a value that allows using it for sawing with a width of less than 20-25 mm. It is made to prevent the woodblock from obstructing the movement of the saw’s guard. But it is enough to screw a wooden block to the parallel bar of the standard stop and its capabilities will be increased, while the minimum cutting width will not be limited in any way.
Please note! Remember about safety. when making cuts less than 15 mm the block does not allow the blade guard to cover the saw blade.
Advantages and disadvantages of homemade circular saw carriage
When creating a carriage for a circular saw you can:
- Achieve optimal dimensions.
- Change the standard appearance, for example, make a radius carriage for curved shapes.
- Choose suitable materials: aluminum, wood, profiles, etc.д.
- Save money. use the tools you have on hand.
However, if you make the guide yourself, there will be a number of difficulties. In particular, it is necessary to have the appropriate knowledge of the process, purchase specific tools for the work, which may not be available to a non-professional carpenter.

Features of design
Immediately before work, you should understand what parts the sled consists of, how they are connected to each other. The structure will be discussed with the example of a tenoning slide for a milling machine.
Dimensions, weight and overall appearance
The size of the carriage is individual and largely depends on the particular saw, its cutting depth, and the purpose of use. Thus, the unit together with the tenoning guide can reach up to 800 kg. To avoid inaccuracies, experts advise making a design drawing.
Structure of the working tool guard
The tool guard is a separate structure with a spigot and bracket, a guide rail and a slide.
Tip! It is desirable to use a handwheel to control the movement of the protective ruler. Screws help to install such a shield and fix it at the top and bottom.
List and arrangement of controls
- Button to turn on, turn off the actuator.
- Mounting Handles.
- Handle clamping the spindle head.
- Spindle stop.
- Buttons for fixing the ruler bracket.
- Colored lights that give a signal.
The device components
The main part of the structure is the cast iron bed, the cast iron table with hard ribs and moving carriage. The guide, in turn, is a plate, clamping and ruler, bearings and constraints for the stroke.
Machine components and assemblies
- Motor with 2 speeds.
- Spindle headstock.
- Connecting mechanism.
- The tile under the motor.
- V-belt transmission.
When making the guided machine yourself, the craftsman must study the kinetic and electrical structure. The kinetic diagram describes the entire operation of the device. its parts and the relationship between them, the principle and sequence of operations.
The design is made according to the kinetic and electrical diagram
A wiring diagram is a graphic document that identifies all the elements of a particular piece of equipment. In general terms with the help of symbolic drawings this diagram shows the electrical energy conversion process, in particular for activating the saw carriage.
The sawmill carriage is driven by an electric motor with 2 speeds which is connected to the spindle via a belt. Thanks to this design, the latter is able to accelerate in 2.3 seconds.
Important! Almost always the motor has a protective mechanism that prevents overheating.
Movable Carriage for a Circular Carriage with Your Own Hands
The movable part of stationary household as it is called but also residential tools is referred to as the carriage. If the pass with circular saws, it helps to fix a small billet and get on its surface an even cut at an angle of 90 degrees, or any other. It is a common task to make a carriage by yourself. Further considered what is useful in the works and what is the correct sequence of operations, so that the carriage for a circular saw at home was fun, but not disappointing.
Before you make a carriage for the circular saw, which would allow to obtain a transverse as it is called angle sawing in small parts comfortably for the user, you need to stock up on the following toolkit:
- an already assembled table with a circular saw mounted on the inside;
- the dural U-shaped profile;
- milling machine;
- epoxy glue;
- Two wooden slats whose height allows you to put them inside the iron profile;
- sheet of plywood under the base of the carriage;
- boards (as stops);
- saw for trimming unnecessary parts of the product;
- screws to fix the parts;
- nuts or other small objects, which will be temporarily placed inside of the fixed profile.
This is a list of the materials and tools that are essential for the construction of a standard construction, which makes a rectangular cut. For sawing under angle 30 as it is named 45 degrees it is necessary to saw a “combined square” from a board or plywood. Now for the sequence of steps.
Before starting the work you must draw two parallel lines on the table at a similar distance from the cutting disc. The dural profiles are placed beside them. Let’s skip to the main steps.

Circular saw carriage | Craftsmen’s work
Metal products act as skids. the carriage slides on them at the time of sawing the workpiece. Along the marked lines the grooves are cut out with a router. Their depth equals the width of the profile.
After removing sawdust and shavings inside of the groove is applied glue, then placed a profile, previously bought over the width of the table (machine). To accelerate the process it is recommended to clamp the profile from the edge of the table with clamps, put a small block beforehand. When the metal and wood is quite “seized”, proceed to the creation of the carriage. It will move on the purchased skids.
Take the nuts and put them inside the profile. It is necessary to put bars in the profile, and glue plywood on them. After making sure that the bars move freely inside the profile, spread glue on them and put a sheet of plywood. Put a load on top of it, so that it pressed moderately to the junction area of the sheet and bars. Wait until it is completely dry.
Fasten the rails with screws. Every 10-15 cm, the number is determined by the width of the carriage. It is important that their length was sufficient to firmly connect the bars and the board, but did not go through.
Many carriages are ready. Now make sure that the product moves freely inside the profile.
From plywood or board cut two parts of similar size, which will be the walls of the product (stops). The rear wall is fastened with screws to the base of the carriage firmly, the front wall only by one so far. For convenience, the clamps are used again.

The user must make sure that both walls are set in parallel. After that, the front wall is also fixed with screws. Then the carriage with the stops is put into the grooves and checked for free movement. Then there is the option to turn on the circular saw and make cuts in the base and walls.
The Unusual PARALLELING STOP and the Circular Saw Carriage
Now it is worth making sure that the kerf carried out has an angle of exactly 90 degrees. For this purpose, takes a casual workpiece, placed in a carriage with an emphasis in the back wall, is included in the saw, made the cut. With a square, it will become clear if the work is done correctly or if there were irregularities.
The execution of the 2 points above gives a carriage that makes the cut of the wooden workpieces strictly at right angles. What to do if you need a corner of 30, 45 degrees? For this purpose, and there are so called combined square.
Its base is wood, the dimensions of which let you put it freely between the front and back of the carriage. The square is vertically divided into two halves. Then the upper right angle (for example under 45 degrees) and the upper left angle (under 30) are cut from it.
Now by fixing the square to the screws or glue at the front or back wall, of course, to diversify the angle of trimming blanks. The carriage became more multifunctional.
Of course, making a carriage by your own forces does not include impossible tasks, and to cope with the service is possible even for a novice.
Below are some aspects of the work, knowledge of which will help prevent slippage.
- It is better to attach a stop to the back wall, which limits the movement of the carriage and eliminates the possibility of injury. For this purpose a small piece is cut from a bar and fixed to the stop on the outer side in the place where the saw blade passes. If during operation the user loses his eye, this element will take upon itself a rotating disk.
- For a smoother carriage movement and reduced wear rate of the sled, it is recommended to wax the inner part of the profile.
- Another thing to think about is how to trim the protruding boards so they do not interfere with the sawing operation. Their length equals the base width.
- during manufacturing, pay attention to the fact that the disk protruded above it a height sufficient for cutting certain workpieces.
- Making a through kerf of the stops of the product, remember. its width can be a little wider than the thickness of the disk, so that the latter freely pass through it.
This to our customer remains what is worth knowing about making a homemade carriage for a circular saw. It is important to keep in mind that this is a tool that does not forgive mistakes, so consider what remains for our client to do aspects of his safety.
the riving knife prevents the blade from jamming during the sawing operation and prevents the material from squeezing the saw blade after sawing.
For safe and efficient sawing there are models that support the connection of a vacuum cleaner to the saw blade. Main purpose is to clean the workplace. Sawdust is blown away, thereby cleaning the place of cutting, as well as the air in the room from wood dust and shavings.
Often manufacturers do not equip their models with adapters for vacuum cleaners, so in this case you will need to buy an additional adapter.
Dust collector enables the sawdust to be “deposited” in a container in order to keep the sawdust in a clean and tidy closed room.
A special laser pointer is usually built into the body of the circular saw. Makes it easier to use and more accurate to cut.
The presence of a light makes it possible to use the saw in dimly lit rooms.
Rubber pads on the handle reduces the strain on the hands and eliminates the risk of the device slipping out.
For your safety, manufacturers come up with various additional features. For example, the most common is a blocking start. To start the saw, two buttons must be pressed simultaneously.

The nuances at work
In conclusion, here are a few subtleties that are useful to know if you want to make a homemade carriage for a circular saw:
- It is recommended to install a thick bar on the bearing wall in the place where the disk goes through it, which will not let the saw jump over the edge of the wall, which can lead to injury.
- In order to give the structure more glide, it is recommended to grind the slides with sandpaper, and periodically lubricate the grooves with a candle burner (made of paraffin or stearin). Sometimes wax is used, but it is not recommended to use it, because when it melts during operation, it will stick to the slides.
- Before applying glue to the parts, blow through the construction from wood dust particles and shavings to avoid unevenness after gluing.
- After sawing through the walls, make sure that the saw goes through freely. To do this, you can make the kerf hole slightly larger than the thickness of the disk.
Important. The craftsman, no matter how experienced he may be, should not forget that the circular saw is a machine of high risk of injury, so when making the carriage and working on the saw with it, you should always be careful and accurate and remember about safety.
Having made the end carriage in such a simple way in the conditions of the home workshop, the master will have at hand a handy, versatile tool, which will find use in most types of carpentry work.
Guides and carriages for CNC with their own hands: types, designs
The mechanics of every machine tool, whatever its purpose and type, includes components that are essential. Therefore, ignoring their parameters is unacceptable. It is generally recognized that such an important component for metal-cutting or woodworking devices are considered to be guides. They are decisive for error-free, cyclical operation.
So, anyone who has decided to build a machine tool, must ensure that it uses high-quality guides for CNC, a positive influence on the functionality of the device. You don’t skimp on accessories.
Basic types of guideways
Machine tools (factory and home-made) are designed and built using a wide range of different types of. This is due to their purpose. milling, drilling or turning work. They can be of two types.
They are used in the equipment of small capacity, not requiring special accuracy and high productivity. Such parts are used in table-top drilling and turning machines and woodworking machines.
The polished shaft, as a type of guide, is one of the most cost-effective. It is the most common.
IMPORTANT! It is made of high-alloy steel, induction hardened and subsequently ground. This treatment serves to prolong the operation time and the shaft is less subject to wear.
- They are fixed at the end points, there is no attachment to the bed, so there is no rigid connection to the table and there are machining errors;
- sagging with increased length, so a maximum of 1 meter is permissible. It is recommended to have an optimum shaft diameter to shaft length ratio (0.06-0.1) in order to achieve normal results.
They are designed with rolling bearings.
Linear bearings have greater clearance than the carriage of the guideways and are less stressed. But it has a number of disadvantages:
- low load capacity;
- low durability;
- making with a solid backlash;
- sensitive to dust and chips on the shaft.
Material for the production of bushings. bronze, brass, caprolon. If tolerances are respected, bronze friction bearings are as good as roller bearings. From time to time, if a plain bearing is worn out, it is adjusted to eliminate clearances. Therefore, the ball bushing is preferable due to the fact that it is available and interchangeable.
It is worth giving a brief characteristic of the other types as well.
- The slotted shaft is characterized by a special raceway for the bush balls. Characterized by greater stiffness and resistance to wear than a conventional shaft, it is used in mechanisms in which it is desirable to mount guides on the ends. In the construction of machine tools are used very rarely because of their high cost.
- The shaft is supported by linear cylindrical rails so that it cannot deflect under the load and its own weight. It is attached to the bed, fixing it securely. Despite the disadvantages expressed in the presence of a large backlash of bushings, their short life, the cylindrical guideways. a large load capacity. Different from linear bearings, the carriage responds differently to the degree of loading. With a small CNC machine tool that has a heavy spindle, there is a chance that accuracy will decrease.
- The purpose of profile guideways is greater accuracy. They are also attached to the bed. Thanks to special raceways, the loads on the carriage are distributed evenly over the surface, and the contact profile of the ball to the rail is an arc. Benefits include good load capacity and wear resistance, and backlash is minimized. The complexities of manufacturing such rails, adversely affect the pricing, they are expensive. This applies in particular to guidance systems from well-known brands with numerically controlled machine tools.
- Roller guideways have a flat raceway and recirculating rollers instead of balls on the pillar module, thus improving all aspects of the guidance system. They are used in machines that mill ferrous metals, steel and stone.
- “The dovetail is chosen for industrial metalworking equipment if increased mounting rigidity is needed. Dovetail guides are designed for sliding planar surfaces with a maximum contact area. They are made as a monolith with a bed. Because of the complexity and laboriousness of the manufacturing and repair process, hobby machine construction does not accept these guides.
Which designs are preferred?
Not everyone can afford to purchase, say, a CNC machining center for home production of small batch components, a lathe of the format type, or for turning operations. But a homemade CNC machine made by hand is realistic. The assembled unit in capable hands will demonstrate patterns of correct part machining.
Assembling the mechanics of programmable machines, usually use homemade linear guides, as there is no need for devices with circular motion. Let’s look at some of the designs used in this process.
Galvanized or chrome-plated tubes
They come in various diameters can be used as rods in the installation of low-power devices. surface grinders, drills or lathes. Grinded cylindrical rod carries a bronze sleeve.
Sometimes a slide is also made without it. The pipes have a low price and are easy to work with.
Although there are disadvantages: low resource (erasure of protective layer occurs after 15-20 passes, after that the steel wears more intensively); no proper level of strength at high loads.
A milling machine in which the guiding mechanism is based on a used dot matrix printer or “Amber” typewriter is effective. With this option will last a long time. It is not necessary to look for very wide bearings, their inner diameter should be equal to the diameter of bolts.
