How to work with a circular saw in wood

The choice of tool depends largely on the individual needs of the person. But to help yourself with such a question, you should know the basic technical characteristics and capabilities of saws in general:

Schematic diagram of a manual circular saw.

Power. This characteristic affects how the circular saw will work, its efficiency. The power of the motor is directly proportional to the diameter of the cutting disc, that is, on strong models you can install discs of larger size. It directly depends on how deep and strong a cut can be made

This is not unimportant when working with hard materials. If this characteristic is neglected, the saw will get stuck in the wood or jump over knots. It is also worth saying that this indicator affects the duration of operation. But right away I would like to note the fact that powerful models have a significant weight

Number of rotations. This parameter affects the ability to work with dense materials

High RPM gives a good cut finish. High-revolution circular saws do not necessarily have a powerful motor. There is no dependence. Cutting depth. Much depends on the motor. The more powerful it is, the deeper the disk will work, as it will be able to be larger in diameter. Depending on the type of tool is selected and the size:

• consumer saw. cutting depth of 4-4.5 cm;
• Semi-professional saw. cutting depth of 5-5.5 cm;
• professional saw. cutting depth of 6-7 cm;
• industrial production. depth of cut in 14 cm.

Different types of circular saw blades.

The latter option can be found in factories, as there are machines designed for mass production. Accordingly, it would be impractical to place such a machine at home.

Cutting depth adjustment. Not all saw models have this feature. But it can also recess the edges of beams as necessary. This option can be presented in a “revolver handle”, which is very convenient. Cutting slope adjustment. This parameter is chosen individually, based on one’s own requirements. Today, most models have such a tilting mechanism

But if we judge objectively, the presence of this function in domestic applications is not so important. It is more necessary for professionals than for amateurs

Choice of cutting blade. Depending on the working material, the cutting part is selected, too

Each blade can separately handle wood, plastic or laminate. But it cannot cut all these materials at once. If you neglect this condition, there is a chance of machine breakage

And it is good if the disk itself is broken, but after all the engine can break down and repair of such equipment. a pleasure not from the cheap. It is also important to pay attention to the size of the outer and inner planting diameters, because not all manufacturers produce a large number of some discs. But the accuracy of the landing diameter is just obligatory. For advice on this matter can be obtained from the store. The manufacturer. In the development of modern construction market problems in the choice of such tools should not arise You can pay attention to both domestic firms, and foreign. In this case, the brand will largely affect the price of the product

Therefore, if finances are limited, it is better to pay attention to Russian manufacturers

Pressure spring

Anyone who frequently uses a circular saw can fully appreciate the usefulness, and even necessity, of this attachment, which ensures absolute cutting precision. especially when cutting narrow boards and planks. while allowing you to keep your fingers at a safe distance from the saw blade. With this spring the part is pressed to the parallel stop without risk of jamming.

It is possible to make such a spring yourself using the same circular saw. As the workpiece is suitable wide plank of hard, thin-fibered wood with the length of 40 to 50 cm. Slat bar is cut at one end at a 45 degree angle. Then make several parallel cuts in the beveled end piece. The result is a kind of comb. Though each of its teeth (about 5 mm thick) is rather soft and elastic on its own, the comb of 15-20 such teeth provides a reliable elastic support.

Kontrapora

Clamp the clamping spring to the circular saw table so that the beveled end edge is parallel to the circular saw blade. Place the second slat as a reference support at right angles to the clamping spring. The spring clip holds the spring firmly in place so it cannot be displaced. The presence of the compression spring does not in any way preclude the use of a protective cover over the saw blade.

The oblique comb at the end of the wide strip holds the workpiece against the parallel stop.

What you need to know about circular saw construction

All amateur and semi-professional models are virtually identical in design. Expensive professional units are equipped with additional elements and functions, but if you do not plan to open your sawmill, you do not need such a tool.

One of the main structural elements is the base plate. It is used to attach the tool directly. Despite its external simplicity, this element is very important. Base plate can be made of aluminum alloy and stamping.

Stamping is cheaper. Such plate is quite strong, but any more or less strong mechanical effects, even the usual fall, will lead to deformation of the product. And you can’t get good cuts from a saw with a deformed base plate. And you are unlikely to be able to straighten it yourself. Stamps have less rigidity than their cast counterparts. So if you have a sufficient budget, it is better to buy a plate with a cast support. The only disadvantage of such products is that they can splinter if dropped

However, here already all depends on the care and responsibility of the user

Almost all saws have a support stand. This element makes it possible to make parallel cuts with relative accuracy. Almost all modern models have a parallel stop. Such a stop is attached at the front, but there are also such models that allow you to attach it both to the back and to the front.

If you have very delicate materials to saw, the base plate must be fitted with a special attachment. Such attachments are usually included by the manufacturer. Professional models have support plates equipped with a special groove that allows working with the guide bar. This element allows you to achieve the highest possible precision. But the guide rails are not usually included, so you have to buy them separately.

How to use the circular saw correctly

Thinking of buying a circular saw arises when you need a lot of work to cut a log or planks along the material. Naturally, to dissolve the boards, if desired, you can use a saw. hacksaw or jigsaw. Craftsmen will manage virtuosely! But if you need to saw in straight lines, then you will need a circular saw specifically for such work. This electric tool is used for cutting wood, plastic and soft metal as well.

Compacting an electric circular saw.

It would seem that the question of how to use a circular saw is quite simple and the answer is clear. But it is not that easy.

What you need to know about the circular saw?

“Circular saws are made simply. They consist of a base plate and the actual saw. Base plate is made of duralumin alloy or pressed iron sheet. Using a simple circular saw a circular saw; 5.2 video how to choose. There are three types of circular saws: stationary, manual and combined.

Even before you start, you need to find the deepest cutting depth. This is a major consideration when selecting a hand held saw. It makes sense to ask for what purpose you need the tool: for professional or household use?

Also the size of the tool matters in this case. As a rule, a medium-sized circular saw is preferred. because of its maneuverability and ease of operation. For a significant amount of work related to battens and thin boards in the construction of the house, a stationary circular saw of larger dimensions will be required. For thin laths, the smallest tool is suitable.

Single-phase circular saws with 220 Watt power can easily cope with cottage and household chores.

For larger workloads three-phase (380 W) power tools are needed. According to safety rules, they must be earthed.

Types of circular saws

For household needs are quite suitable manual options, capable of transverse, longitudinal and oblique cuts. They are easy to maneuver, lightweight and relatively inexpensive.

Some models allow making a cut not only from the face, but also in any place thanks to a special immersion function. Thanks to the possibility of tilting relative to the plate, such models cut material at different angles.

The base plate of such a tool is made by stamped method (suitable for household purposes) or cast (for professional tool).

Large jobs require a stationary circular saw with a box-type frame. They were used before. Modern models are made very compact and can be placed on work surfaces, such as workbenches.

Professionals need more massive tools that are placed directly on the floor of the room. They can influence the cutting depth thanks to the sliding table. Blade remains stationary while working. How to make a table for a circular saw with their own hands? See photos and videos of their own circular saws. This greatly expands the possibilities of the circular saw.

If work is often carried out with a variable workload, combination saw blades are the right choice. They differ from handhelds in that they have special mounts in their body, allowing stationary operation on any horizontal surface. In this case the saw is clamped with the blade upward.

Benefits of electric circular saws

Various types of circular saw blades.

There are saw models that control the tool’s load during operation, protecting it from overheating, and are capable of controlling the speed of the mechanism.

Most circular saws are equipped with an overload indicator and their motor brushes. Changing discs is very safe because of the built-in quick braking system and locking the machine’s motor.

A number of electronic saws allow the number of revolutions to be measured as the blade moves during sawing. This feature allows you to work not only with wood, but also with plastics and some soft metals.

advanced models have an electronic soft start system. It makes these tools quickly gain speed at a steady speed.

It is very difficult to cut oneself because such models have a protective cap that protects from the saw’s teeth. It comes away from the blade smoothly and without jerking when you start sharpening. A number of these types of tools are equipped with a pendulum shroud and feed roller.

Many models for both professional and home use have special outlets to connect a vacuum cleaner. Despite the reduction in maneuverability, such a tool lasts longer, because the number of negative factors is significantly reduced.

A little about the available teeth

When selecting a saw for the job, the characteristics of the teeth must be taken into account. In this video I show how to make a homemade guide for handheld circular saw. This is necessary because a particular material requires a different type.

Circular saw blades with standard teeth are used for soft wood and plywood.

For hardwood or chipboard, special carbide teeth are suitable. In addition to the special shape and a larger number, they have a bit of a tungsten carbide tip.

For dressing work, such as ripping boards, a blade with a small number of teeth (up to 24) is the right choice. The fewer the teeth, the bigger the size. This makes the blade faster to cut, but the cut will be coarse.

For a clean cut fit discs with teeth to 36-48 units. Working with hardwood material or boards with nails would require a 54-piece trapezoidal blade.

The inclination of the teeth can be positive, the kind that cuts wood. Disc with and negative tilt are used for clean cuts in aluminum and plastic.

What can be done with electric circular saws

Electric circular saws allow you to work with wood and wood-based products in different ways, which depend on the type of tool you choose.

Types of work with a hand circular saw

The following types of work can be done with a hand circular saw:

Circular saw selection

The circular saw must meet the requirements of safety technology, to be clear in use. The tooth profile and number of teeth on the saws must be appropriate for the type of work to be performed. The blade should be flat, with no surface distortions. Before starting work check flatness of blade with ruler. For a straight cut line the sharpening of the saw is decisive. Sharpened saw teeth should not shine at the corners. The presence of a glossy finish indicates insufficient ground metal. Burrs, bends and twists should not be present on the cutting edges of the saw, the presence of such metallic formations spoil the wood.

The equipment is equipped with a strong and sturdy support base of cast aluminum. The operator will not encounter the problem of the blade jamming, because the device has a wedge-shaped blade. safety when working with such tools is of paramount importance, in this case the protection against accidental start is ensured, which is made possible by the use of a fuse.

Working rules for circular saws

Working with hand and stationary circular saws requires observance of a certain sequence of actions, which we will consider below.

Manual models

If it is necessary to work with a manual circular saw, then at first it is necessary to pick up a saw disk corresponding to the forthcoming type of work, to make adjustment of the depth of cutting and inclination of the equipment. Depth of cut with a circular saw is set according to the following principle: the tooth of the circular saw blade should protrude from the workpiece either up to the half or completely.

• secure the workpiece to the workbench using clamps (do not hold the workpiece by hand);
• place the tool on the workpiece so that the saw blade does not touch it;
• start the machine’s engine and wait for the tool to reach full speed;
• holding the device firmly in hands, make sawing by pressing the sole of the hand saw to the workpiece;
• When you have finished sawing, make sure that the hood is back in its original position, and then turn off the machine.

Important! Never leave the machine unplugged with the start button locked. The saw will start up when the mains are switched on and could cause injury to persons in the vicinity.

Stationary models

To start working with the circular saw unit, proceed as follows.

• Look for a circular sawblade of a suitable diameter for the material to be machined and install it on the shaft of the machine. Use a dial gauge or an ordinary caliper to check the distance from the saw blade to the guide slots of the table. Check the clearance at the beginning and the end of the blade. The maximum discrepancy should not exceed 0,05 mm.
• Adjust the blade to the desired height above the workpiece. The saw must be no higher than the height of the cutting attachment.
• Set the parallel stop at the desired distance from the saw blade. On this distance depends width (length) of the product, which will be obtained after sawing the workpiece. It must also be strictly parallel to the grooves on the worktable (displacement of no more than 0.05 mm).
• Set the riving knife. It must be approx. 5 mm from the cutters and in line with the saw blade. It’s easy to check with a ruler between the tool’s cutters.
• Turn the machine on, wait for the engine to reach full speed, place the workpiece along the parallel stop and then, while pressing it against the table and the stop, make the saw.

Denise Lynn’s Dream Book

The saw can symbolize a. fit. Or it could mean building something new. In general, this is a very good omen, foreshadowing work, creation, construction of something new.

Sawing also means. pruning trees. Are there areas in your life that should be thinned out to allow new shoots to break through? This sign may refer to emotional wounds from the past that have begun to heal, but still make themselves felt. Analyze other symbols and situations to pinpoint areas that you should heal as soon as possible.
