How to trim a board with a hand-held circular saw

Device for cutting boards with a circular saw

This guide is very easy to work with. The base with the ruler is fixed to a workpiece, for example, to chipboard. You can fix this by using several options. In the first method, part of the cut sheet will be located on the side of the saw blade; in the second method, under the base on which the guide ruler is fixed.

The length of the sheet is 2 marks on the side, which corresponds to the specified cutting methods, at the distance where the cut is located. The distance between marks should be maximum. It is important to consider the thickness of the disc. The base of the ruler is mounted on two signs and secured with clamps. The depth of the clamping jaws should ensure their installation so that at the end of the cut the saw can move freely from the letter.

If the guide ruler is long, then the cross-section is not very convenient. Therefore, it is advisable to make a design that is shorter. For example, for cabinets that are 60cm wide, you will need to make a guide that is 1m long.

Such devices are only suitable for working with materials that have a large width and length. You cannot cut a board into flat rods of this design.

End antiseptic: the best choice

A lot of means have accumulated to combat cracking and rotting of the ends. As a rule, their action is aimed at creating a moisture-impermeable film at the end, which prevents its evaporation. As a result, the difference in drying speed is leveled out and the material does not crack.

The following means are used:

inexpensive oil paints;
paraffins and waxes;
a mixture of lime and drying oil;
a mixture of chalk and tree resin;
bitumen resin or mastic.

The above methods work, but have a number of disadvantages:

The created film does not allow moisture to pass through and does not breathe, which leads to disruption of normal drying.
The lack of an antiseptic effect can lead to preservation of the infection inside and its explosive growth.
Paraffins and waxes melt in the sun and are easily scraped off by friction.
Bituminous mastics and resins look unsightly, emit an odor and burn.
The surface treatment is short-lived; the products are gradually washed away with water.

The use of folk remedies and various cheap substitutes does not provide the proper level of protection. They cover the surface of the end from moisture and clog the capillaries, but do not provide antiseptic protection and do not have a fungicidal effect.

Only special products for processing ends are distinguished by effective and balanced action. Here you can also find a variety of compositions that can be intended for temporary protection, these are so-called transport impregnations, or for permanent protection of finished products. As a rule, such drugs combine several active ingredients at once and have a complex effect:

The material is impregnated with a mixture of antibiotics and fungicides penetrating into its deep structures to suppress bacteria and mold fungi.
They deliver compounds that prevent the subsequent development of new fungi and bacteria.
They create a film on the surface that acts as a membrane that reduces the penetration of moisture. As a result, drying proceeds evenly, and shrinkage deformation does not lead to the formation of cracks.

An example of such a product is the GOODHIM TOR GBS end sealing primer. This product is excellent for large-sized lumber and is used by professional builders for processing the ends of logs, edged boards, rounded and laminated veneer lumber. The advantage is the low price and the presence of a double effect: antiseptic and against cracks.

Finding a good end protection product is not difficult. Today, there are many domestic and foreign brands on the shelves, the products of which are worthy of consideration. Let's take a look at the most interesting of them.

How to make a simple guide and removable device with your own hands?

Diagram of the bearings of the circular saw assembly.

It makes sense to make a simple reference book. To make cuts with a portable circular saw, you can purchase an expensive guide at the building's supermarket, or make a few homemade projects in a workshop if you need to cut a large number of sheets. However, you should know that there is a simpler solution - to make a device from scraps that are not used.

A simple homemade miter template for a circular saw

To make your own saw manual, you need to select a factory edge strip of plywood or hardboard 25-30 cm wide. The strip is fixed along the cutting line so that the base of the tool moves along the flat edge. If foam padding is used to protect the saw blade, it must have cutouts for the jaws.

You can also make a cutting device for this type of saw. A clean and even intersection in some cases is quite difficult to do with the introduction of a circular saw. It's almost impossible to fully control the tool, and pieces of material fly off more often than not, leaving behind chips and jagged edges. So it makes sense to try to make a cross-cut design out of a few pieces of wood and an angle of aluminum.

To plan or not depends on your machines

After the boards have acclimatized in the workshop, you can choose one of two options. Either first level one face on a planer and thicknesser the other to make them flat, and then proceed to straighten the edges, or straighten the edges, leaving the faces untreated. We recommend the first option, since some methods of preparing the material work better when the faces of the boards are cleanly planed.

However, the choice may be dictated by the capabilities of the available machines. For example, you cannot process a 200 mm wide board on a planer with a maximum planing width of 150 mm. And by sharpening both sides of the board in a thickness planer, you will not make them flat, but only parallel to each other. In this case, make one of the edges of the board straight by first sawing it evenly on a saw to the required width, level one face using a planer, and then plan the board to the desired thickness in a planer. If the required width of the workpiece is greater than the length of the knives of your planer and jointer, then simply saw it lengthwise into two or three sections, sharpen them and process them with a thickness planer, aligning the edges. After the plots become straight and rectangular in cross-section, connect them again into a shield, gluing them with edges.

How to make a manual template yourself?

Guide bar for a circular saw - this can be made from improvised means by cutting a flat sheet of wood.

When you need to make long cuts with a similar saw, you will need to spend a significant amount of time to make all the measurements necessary to set the mowing line guide and markings exactly to match the width of the base of the structure.

To simplify this procedure, you need to cut a template from fiberboard that is equal to the width from the edge of the tool to the inner edge of the saw blade. The template is then cut to the length of the tool base. To use the template, you need to align its edge with the cutting mark in the product, and on the other side attach a straight guide and secure it with a clamp.

You then need to repeat this procedure on the second cut mark on the other end of the workpiece that is being cut. Such designs can be made for circular saws or electric saw blades.

Means of protection

To protect wooden structures, special chemicals are used. They are produced in the following substances:

in the form of aqueous solutions;

Treating wood with an aqueous solution

In the practice of home craftsmen, the simplest method of wood processing is used. It is immersed in a bath with a solution of iron or copper sulfate for a day. Or they are soaked in used hot oil. A simple, fairly effective method of protection is treating a wooden fence with turpentine or tar. The main thing in the fight against wood destroyers is to create an environment in which they cannot live and reproduce.

Fungi and insects love moist air coming through the pores of wood, which can be closed and clogged. This will create unfavorable conditions for the existence of tree pests. To protect wood products that are constantly exposed to moisture, a special composition has been developed - liquid glassine. It contains antiseptics and herbicides.

The solution easily penetrates into boards and wooden posts, displacing water from there. Then it polymerizes and tightly closes the cracks and pores, without letting in either air or liquid, without which life becomes impossible for wood pests.

How to make a crosscut from a manual circular saw at home

Hello dear readers and subscribers of Andrey PLA's blog. In this article I will tell you how to make a cross-cutting device from a hand-held circular saw for your home purposes, while spending a minimum of money on production. A hand-held circular saw is a good helper in your household, with which you can do “very big things”!

I consider it inappropriate to focus attention on the term “circular”, since everyone already has first-hand knowledge of what this device is, and there are enough thematic materials on my blog. I will try to tell you what saw and convey as much useful information as possible for a visual presentation.

pendulum;
combined;
With a broach.

The pendulum trim is the following design. The basis of any machine is the bed. The table is fixed on it, which in turn is made on a rotating mechanism with a ruler. This device solves the problem of setting the cutting angle with its adjustment.

The cutting angle can be adjusted by moving the work table to the plane of the bed. The saw element is strengthened by a lever and spring-loaded by a hinge. Using a pendulum, the saw moves in the vertical direction.

As for the combined model option, the cutting angle can be changed if necessary in two directions. The device is the same as in a pendulum saw, only an additional hinge is added to the design. As for changing the cutting angle in the horizontal plane, it can be changed in the horizontal direction, which in turn is opposite to the mounted drive.

a saw with a broach makes it possible to move the cutting element both around the axis of the hinge mechanism and in the direct direction along the cut. This was achieved thanks to the installed guides (pictured below).

For convenience on a cross-cutting machine, operators use a special device for cross-cutting on a circular saw, which is called a miter box. A simple design, which consists of a tray for boards, a clamping piece of plywood or a second material, clamping fixing elements (clamps, etc.). How does this device work? I will try to answer this banal question simply and clearly.

The board is placed in a tray and pressed against a sheet of chipboard. Fixed with a clamp and a hand saw, circular saw, or grinder, the workpieces are sprayed through special side slots. Often, a miter box is used to cut material at an angle of 45-90 degrees in home workshops on Tsirkulyarki. Using this device, you can quickly cut the board into a pallet or board.

After all the information, you have an idea of what cross-cutting is and why it is needed. Next, I will tell you how to make a cross-cut trim using a hand- held circular saw using scrap materials with your own hands.

The base of the structure was a box made of chipboard. It has a “U” shape. Confirmants are knocked down and fastened together. To prevent this shelf from moving, it is attached to the work table (workbench) with clamps.

The base under the dust is screwed onto the shelf from above. Fastening is also carried out by confirmants. We ensure that the planes are perpendicular, since the saw blade will be aligned along the edge.

I make sure the sole is aligned along the edge. This will prevent shifting and fidgeting. We screw strips of chipboard onto the sides with self-tapping screws. In this way, the positioning of the sole is achieved.

the saw is fixed with clamps and clips. You can make wing clamps. This is the device for cross-cutting on a circular saw in this version. This device is popularly called “Foreman”.

Next to the base to the table we fix the “table” base. The only drawback is the reduced cutting depth of 15mm. Therefore, you have to place the profile as close as possible to the saw blade.

After making a test cut, we obtain a cutting line based on the stop. Thus, I was able to construct a circular cutter with my own hands. This design of the device copes with the task one hundred percent. If you still can’t design this type of equipment or simply don’t have time to do it, you can use the services of renting a circular saw with a trimmer at affordable prices in specialized workshops.

Another good tool for working with wood is a thickness planer. What is it? It can be divided into two types - manual and in the form of a full-fledged thickness planer. As a rule, the manual version is needed only to transfer data from the drawing to real material and workpieces.

As for the thickness planer, it, in turn, is more functional. In addition to transferring information, you can carry out full processing of workpieces. Such equipment is purchased by furniture factories and can also be found in everyday life during the construction of private facilities. This is what a surface planer looks like with a circular saw and a trimmer, I attach a photo below:

As for the usual planer device, it consists of three parts. A supporting stand with a dimensional ruler, a clamping device and devices for applying markings to the part. They are usually made from hardwood material.

How to treat a wooden fence

When building fences, homeowners often choose wood. This is a very aesthetic building material, although its service life is not as long as, for example, a brick fence, metal profile or chain-link fence. The owner is faced with the question of how to treat a wooden fence and extend its useful life. Proper wood processing allows you not only to protect against the destructive forces of nature and wood pests, but also to make it even more attractive.

Wooden fence treated with special means

The advantage of sawing logs with a chainsaw

Spraying onto boards can be done using tools such as an electric chainsaw and additional accessories designed to simplify the work. When choosing certain products, you need to focus on the amount of work expected. Stationary sawmills are expensive and are purchased only if you plan to organize a business to create boards.

READ Can a Miter Saw Cut Metal?

The most accessible tool for the job is a chainsaw. Such devices have several advantages over electric ones:

the chainsaw can be used anywhere, regardless of the availability of an electrical outlet;
the tool is suitable for working in conditions of high humidity;
professional chainsaws are significantly more powerful than electric ones;
You can use the chainsaw continuously for an hour.

To cut logs into boards, a special frame is used together with a chainsaw, which is attached to the device and allows you to create boards of the same thickness. A device is also needed to secure the log in one position. In addition, you will also need a guide.

HOW TO cut boards smoothly with a HAND circular saw!!!

Since household gasoline saws are NOT designed for heavy loads, you should use professional tools when sawing logs. When choosing, pay attention to devices with a power of more than 7 horsepower. Before work, the fixed frame is adjusted in accordance with the selected width of the boards. To create a frame, you can use legs from a school desk or metal corners.

Specifications

If you have realized the need to purchase this equipment, then you should carefully familiarize yourself with the main technical characteristics of plunge-cut saws. They may differ slightly in their design and performance properties.

When choosing a saw to solve your problems, the main attention, first of all, needs to be paid to the power of the installed electric motor. In most models that are available on the market, the power unit present in the design of plunge-cut saws is designed to operate on a 220 V network.

This makes it possible for even a home craftsman to use this tool. When choosing equipment, you should also take into account the fact that the speed at which the workpieces will be processed depends on the power of the electric motor with which the saw is equipped. Additionally, the hardness of the parts, relative humidity, and the depth of cut should be taken into account.

The main technical characteristics of the saws are the following:

maximum depth of cut. This parameter largely depends on the feed unit, the diameter of the saw blade, as well as the angle of inclination of the cut. For plunge-cut saws it can vary from 45 to 90 degrees; power of the installed electric motor; distance from the blade to the edge of the support platform; saw parameters

The maximum and minimum diameters should be taken into account, taking into account the seat size and thickness; drive shaft rotation speed. In order to reduce weight, manufacturers use gear transmissions of torque from the engine to the cutting tool in the design of such tools; diameter of the pipe for connecting the chip vacuum cleaner; weight of the structure.

As an additional characteristic when choosing equipment, cutting speed should be taken into account. This parameter depends mainly on the density of the workpiece, as well as the parameters inherent to the saw blade

In order for the processing of wooden workpieces using a plunge-cut saw to occur quickly, and the final result to be of high quality, it is necessary to choose the right tool. To do this, you should know the main types of tools, as well as be able to understand the symbols on the saw blade.

Long sawing technique

The most difficult stage of the process is making the first cut. To do this you need:

install a leading ruler, which consists of two boards that are fastened together at an angle of 90 degrees;
after this, it is necessary to place the sawn log on the supports and fix it;
then it is important to check whether the log is level;
at the next stage it is necessary to secure the leading ruler to the supports using self-tapping screws;
After this, you can start creating the first cut.

Processing of wooden ends

The cut must be processed immediately after constructing the structure. While log trunks retain their natural functions and require at least a year to dry completely before processing, the ends need immediate protection.

When impregnating logs, you should pay attention to the order of this procedure, and also take into account that the wooden beam must be able to breathe and evaporate moisture. Therefore, if you are working on the external parts of a wooden structure, then you cannot carry out internal treatment of the premises.

End protection is carried out in several stages and requires special tools:

Before using the material to cover the timber, it must be given a smooth, even surface using a chainsaw or other tools;
The next stage is sanding the wood section. By sanding, the timber is cleared of irregularities, stains, and mold, giving the wood a smooth surface. Darkened wood is removed before painting.
Applying material or impregnation to protect the end.

Mike VIZ:

Hello, you have already seen this circular in your frame several times. Is it AEG or another company? Can shoot a review, I choose myself dust, I would like to hear advice from an experienced person on what to pay attention to.

Features of sawing logs using a chainsaw

Creating additional equipment for sawing logs is quite simple:

To create a support, a frame is used, which can be created from the legs of a school desk. The most suitable pipes are with a square cross-section of 20 × 20 mm.
When constructing the frame, it is necessary to create 2 clamps and secure the crossbar at one end. This element must have holes for tie bolts. A protrusion for the tire is created in the middle.
In order to cut a log lengthwise, it is necessary to construct a support frame, the width of which must be at least 8 cm in length.
For ease of operation, a handle should be welded to the frame.
Before carrying out work, you must carefully check whether the frame is securely fastened to the tire.

Using a homemade tool is quite simple. Before sawing, you need to install 2 sawhorses - they will be used as a support for the log. In addition, a metal strip or flat board , which will serve as a guiding element.

Lightweight nozzle

Such devices are often used, but they should only be used when creating boards for fences or sheds. This is due to the fact that the attachment is secured to the tire only on one side.

Setting up a circular saw before work

Before you start sawing, you need to install the blade and make sure it is firmly in place. The casing should open and return to its original position without any resistance. It is also worth checking whether the riving device is positioned correctly. After this, run the dust for 10 seconds in idle mode to make sure that it is working properly.

To set up a circular saw, you need to adjust the desired position of the guide pin and cutting blade using a caliper. When checking the position of the teeth in front and behind the disc, the difference should not be more than 0.05 mm. You also need to install the riving knife and blade so that they are on the same mowing line. Special washers are used to fine-tune them. To ensure that the tool and table vibrate less, you need to tighten the mounting bolts well.

Fence restoration

However, a painted fence is also not durable. After no more than 4 years, it should be subjected to new treatment, and possibly replacement of wooden poles. Begin by removing the old cracked paint with scrapers or metal brushes. After which you need to make sure that there are no rot spots on the wood and that it is not damaged by insects. Instead of damaged boards, new ones are installed and treated before applying paint.

Extending the life of the fence is ensured by proper maintenance. Regular inspection allows you to identify any damage that has occurred, repair it in a timely manner, and also replace fence posts. Do not place trash, grass clippings or brushwood close to the fence. If well maintained, a wooden structure will please the owner for many years.

What can you do with a hand-held circular saw?

Manual circular saws are suitable for performing a whole list of jobs:

trimming several wooden blanks at once, which lie in the same plane;
trimming wide boards for which pendulum dust cannot be used (you will need a parallel fence)
trimming boards when laying floors;
trimming workpieces at an angle (you can use a guide or do without it)
longitudinal spray of workpieces at an angle;
sampling a quarter in a board or timber;
cutting sheet materials with the introduction of a guide;
cutting organic glass and plastic;
using a hand saw as a stationary one by mounting it to a table.

You're lucky: there's no warping

If the selected board falls into this category, you can consider that the deal is in the bag. Regardless of the length of the board, you can quickly get a straight edge using a planer and jointer . If you don't have one, use a circular saw to file down the rough edges of the board.

A straight edge on this type of board can also be achieved using a router. If the face of the board is not planed, use a guide board that has a smooth face and a straight edge, attaching it to the top of the workpiece, as shown in the photo below. Use a guide cutter with a top bearing. Install the guide board with a slight indentation from the edge of the workpiece - this distance corresponds to the volume of material that will be removed during processing. If necessary, make two passes.

When using this method, press the straightest edge of the board against the rip fence to avoid kickback. Having filed the opposite rough edge of the board (photo on the left), move the longitudinal fence, turn the board over so that its new edge faces the fence, then file the second rough edge (photo on the right).

If the sides of the board are planed, fix the guide (it can be a flat board or a homemade or purchased tire) on the workpiece so that when moving along it, the router removes a layer no more than 1.5 mm thick in one pass (photo below) Make as many passes as required to obtain a straight edge.

With the router sole on the guide board, guide the cutter bearing along its edge. Remove no more than 1.5 mm of material in one pass. Use a cutter with an upward or downward helix, or a straight cutter whose blades are longer than the thickness of the workpiece.

Grind a small chamfer on the edge of the face facing the cutter - this will prevent the workpiece from getting stuck when it is fed.

A straight edge can be made on a router table, but it requires a little more advanced setup. First, clamp a straight or spiral cutter into the collet of a router fixed to the table and set the cutter overhang to be slightly larger than the thickness of the workpiece. Adjust the front of the rip fence so that no more than 1.5 mm of material is removed in one pass. Place the back of the rip fence flush with the cutter blades. If the rip fence does not have separate front and back parts, use a clamp or double-sided tape to attach a piece of laminate plastic to the back half of the fence with a thickness corresponding to the layer of material being removed (photo on the right).

How to cut a board smoothly with a circular saw

Unlike a pendulum saw, which is stationary, a circular saw is more difficult to make an even cut. This will not be a problem if the board or beam is narrow, but when sawing a wide workpiece or when making longitudinal cuts, you need to know how to make the cut as precise as possible. To do this, you need to follow the following sequence of actions:

There should NOT be anything underneath the piece of material you will be sawing. The circular saw blade should not be cutting anything else. For example, we would never place a board on a concrete floor - use a sawhorse or a cutting machine table instead.
Mark the line along which the saw blade will go. Use a tape measure, ruler or square for this.
Adjust the cutting depth. The blade should barely protrude beyond the workpiece. For example, if the thickness of the workpiece is 40 mm, the cutting depth should be 45-50 mm.
Check the condition of the protective cover. It should rise gently when the saw is lowered onto the workpiece, and immediately close the working part when it is raised.
As you begin to cut, look at the front right edge of the blade and align it with the mark on the material.
Look at the right kerf guide of the circular saw for right angle cuts, and the left one for 45 degree cuts.
Start cutting the material. Keep an eye on the guide at all times to ensure an even spray.
Keep the saw blade flat on the material at all times.
Push the dust hard enough to cut it, but don't push it too hard to overload the motor. The hardest woods should be cut with minimal force.
After finishing cutting, make sure that the safety guard returns to the closed position.

Preparing the workplace for work

You need to remove all unnecessary items from your desktop. There should be no tools, keys or consumables. In addition, you need to ensure a free approach to the table. The floor in the work area must be dry to avoid accidental slipping. The machine must be grounded.

READ How to Set an Angle on a Miter Saw

There are also requirements for the operator’s work clothes. Clothes need to be tucked in so that there are no flapping ends. If you have long hair, tie it up and hide it under a hat. Wear safety glasses and a respirator. It is recommended to use hearing protection as the noise level can be quite high when using a circular saw.

Before you start dusting, you need to check it for defects in the saw blade and make sure that it is fastened properly. Check to see if the riving knife is installed correctly and then check that the guard is working properly.

If the saw has a short cable, you may need an extension cord so that you can comfortably move around the work area. It is advisable to use a circular saw with a soft start function so that the tool does NOT jerk when starting.

Professional equipment

Now let's talk about professional equipment. Let's consider the cross-cutting saw ZUBR ZPTP-255-1800. The tool is used for cutting wooden parts and thin-walled metal. Why combined? This is because it can be used to both trim workpieces and work like a circular machine.

Main advantages of the model:

Mobility;
Compactness;
Functionality;
Safety system.

This machine combines a crosscut and a circular saw at the same time. The adjustable head position allows for high quality cuts. The machine allows you to make longitudinal cuts at any given angle. The equipment is equipped with a locking mechanism for turning on the drive and raising the protective casing. This model has the ability to connect an industrial vacuum cleaner to keep the workplace clean.

You can buy a circular cross-cutting machine for around 15 – 20 thousand rubles.

Another good option from all the gray mass of equipment is the Makita MLT100 table miter saw.

It is used both in everyday life and in professional production in workshops and workshops. The design of the machine allows it to be moved on a special trolley and can be easily mounted in a designated place on a workbench. The sliding table allows you to work with large workpieces. The table can be rotated both to the side and forward. The long service life of this equipment is increased due to the high quality of parts and materials used during assembly.

Allows you to make cuts both vertically and at a specified angle. The high precision of cutting parts is due to the presence of clamps, guides, scales with degrees and a ruler. The equipment combines a cross-cutting machine and a circular saw at the same time.

A separate advantage is the presence of an engine speed stabilization system, which in turn plays an important role during the initial start-up of equipment.

Electric brake included. There is a connector for connecting a dust removal device, useful for large volumes of work.

Proper operation of a circular saw

A hand-held circular saw is one of the most important tools in woodworking. It significantly increases the speed of working with wood or plastic, sheet materials, boards and timber. Most often it is used for cross cutting, but this tool can also be used for sawing along the grain of wood. In this article we will describe in detail the range of uses of circular hand saws, their setup before work, operating techniques and safety rules.

Safety tips when using the saw

Before starting work, run the circular saw idle. As you cut the material, observe the following rules and recommendations:

When starting work, you must stand on the left side of the machine so that if the workpiece is accidentally thrown out, it will not hit you.
Make sure that there are no nails, pins, pieces of dirt or concrete in the workpiece or on its surface that could interfere with the cut.
It is prohibited to pass objects over a running circular saw.
If there are knots or cracks in the wood, you need to move slowly when approaching them.
When changing the saw blade, be sure to unplug it.

Hacksaw - simplicity and safety

A hacksaw is a simple tool that is quite suitable for the job. And although the cutting speed is low and considerable physical effort is required, such a saw is the most acceptable option for home use.

It is not difficult to cut wood correctly with a hacksaw. The main condition for a high-quality cut of the material is to make the cut correctly. To simplify the task, you can use a regular flat block, which is used as a guide.

The question often arises of how to cut a board smoothly with a hacksaw at an angle. For this purpose, a special carpentry device is used - a miter box. Moreover, it will help not only to make a cut at the desired angle, but will also allow any beginner to cut the board smoothly.

You can also saw off the timber with a hacksaw. The only problem when working with such a workpiece is that you have to put in a lot of effort.

The last option is to use an angle grinder with a wheel with teeth installed for the work. But since the “grinder” is not intended for cutting wood, this method can only be used as a last resort: attempts to cut a board can result in serious consequences. It’s better to use a hacksaw - it’s labor-intensive, but safe.

How to adjust the dust for an even cut?

The saw blade must stand strictly perpendicular to the support platform. This can be seen both in the position of the disk and in the degree scale on the adjusting arc. If the disk is at an angle:

The locking screw is released.
The platform tilts to the desired position.
The screw is fixed.

You should be more careful with tightening. On some models, if it is too heavy, the thread can be stripped or the head can break off.

Then it depends on how and what generates dust.

How to cut an unedged board?

Trimming the wane of a board a manual circular saw can be done in two ways:

How to trim a hand-held circular saw quickly and accurately

By marking with a pencil (marker, sharp tool, etc.).
Along the guide. To do this, a block, corner or factory guide rail is attached to the board with clamps or self-tapping screws. Dust, presses the edge of the saw platform to the guide.

Cutting along a guide usually produces a smoother cut.

We also recommend reading a useful article with reviews of the most popular and best circular dusts for the home.

Why does it cut crookedly?

The disc cuts the line it is directed towards. In this case, the tool should be held or pressed against the guide firmly enough so that it does not move to the side.

If, despite all efforts, the cut turns out to be crooked, the reason is a waste disc. A scorched disc with blue spots on both sides may begin to wobble at the slightest heat. If the teeth on one side are normal, but on the other they are knocked out or blunted, dust may be introduced in one direction, no matter how hard you try to hold it.

Straight edges start in the shop

When purchasing lumber, select the best boards possible, paying particular attention to the grain pattern and how it will look on the finished product. You can purchase unplaned material, either having two planed faces or planed on both faces and on both edges. The latter option, being more expensive, often solves the problem of obtaining a straight edge. However, even such boards can warp. Warped boards, although difficult to work with, can also be a good material. A flat board with curved edges (photo on the right) can easily be processed to straight edges by following the decision diagram.
