How to unwind a board with a hand-held circular saw. How to do it

Sawing logs into boards with a chainsaw: What you need for that

Some people have the opportunity to take a certain area in the woods to cut logs, but how do you cut a log into boards with a chainsaw if you have never had to deal with it? Those who have been engaged in logging for a long time can do it without any devices. it is enough for them to beat off on the trunk a longitudinal line for a trimmer and use it to cut a bar or plank.

But if you have never done it, you need certain devices, which we are now going to tell you about and also show a thematic video in this article.

How to cut fiberboard?

Depending on the thickness of the sheet of fiberboard you should choose a tool for cutting it. Better, of course, to buy a special machine tool, which should be able to cope with the material of any thickness. But for a single solution to the issue, for example, if you need to repair a couple of drawers in a furniture cabinet, no one will get precious equipment. Therefore, for such works, performed at times with their own hands, the subsequent tool will be suitable:

Hand circular saw ruler or how to saw evenly.

Very smoothly it turns out to saw with an electric jigsaw, if it has a laser illumination of the direction of movement. Perfect evenness is also observed when working with a circular saw. It must be said that the electric jigsaw and circular saw are quite popular tools in the household, so these methods are quite relevant and available to home handymen.

If the thickness of the sheet Fiberboard is not more than 3 mm, then it will not be difficult to cut a few parts and an ordinary sharp knife. It is not uncommon to find a milling machine in garages, so milling will come in handy for making small workpieces out of fiberboard. For uncomplicated rectilinear workpieces you can saw a sheet of fiberboard with an angle grinder.

In special cases, take the right tool for hire, which will cost inexpensive, or turn to specialized companies.

Sawing a chainsaw log into boards with a fixture

When it is necessary to cut a log lengthwise with a small power chainsaw, then you can’t do without a special device and skills. This is how the YouTube channel Carpentry with our own hands describes it.

Sawn timbers

The basis of the home-made sawmill is the carriage, which is welded from 25 mm sectional tube. Two guide nipples with a cross section of 30 mm are welded to the carriage. To fix the height of the carriage, two M8 bolts are put on each pipe.

Carriage with rails

The sliding part of the fixture is T-shaped. It is also made of 25 mm section pipe. Each stand has clamps, which fix the guide bar of the chainsaw.

Supports with clamps

To allow the chainsaw chain to move freely, 40 mm thick metal jaws made of 4 mm thick are welded inside the clamps.

Jaws in the clamp

The guide bar must run smoothly on the guide rails when sawing, that’s why rollers are fastened on all corners from below. You need inexpensive furniture casters made of plastic.

Carriage with rollers

Assemble the fixture before fitting it on the guide rail.

Assembled fixture

As a guide for the carriage one section of aluminum ladder is used. The carriage is mounted on top of the ladder and slides effortlessly along the guide rail with the rollers.

Carriage on ladder

The fixture is designed to work with a 3.1 kW Husqvarna 555 chain saw.

Husqvarna 555 saw

Choose a special chain for the longitudinal saw. It has a different chain pitch and cutting edge angle. The chain sprocket on the chain saw is matched to the pitch of the links.

Comparison of a rip saw chain

Sawing depth of a log depends on the size of the guide bar. No Husqvarna makes a bar with an optimal length of 55 cm, so you buy a Partner bar, and choose a chain with 68 links to fit it.

The Partner saw chain

To work, the device is mounted on a chainsaw. First attach the bar to the bar and fasten it. Then a carriage is put on the poles.

The ladder is attached to the log with brackets and planks.

Attaching the ladder

After installing the chainsaw with a device on the ladder choose the size of the cut and by this size set the height of the carriage on the guides.

Setting the size of the cut

The cut is made by moving the chainsaw carriage along the log on the guides.

Saws for logs

Types of equipment used

We will consider some options for carrying out works with their own hands and tell about the devices used, it is up to you to choose the solution that will be best for you in a particular situation.

Board sawing

Such type of work as a longitudinal cut of a board to size can be done in several ways:

• If the amount of work is small, a manual hacksaw can be used. True, you will need a special variant for longitudinal sawing, which differs in the shape of the tooth. Instructions for the work are as follows: it is necessary with the help of an angle and a tape measure to conduct a thorough marking, then outline a clear line for the trimmer, then the element is carefully secured so that in the course of work the board did not move;

The longer the length of the board. the more difficult it is to carry out the process qualitatively

Important! In manual processing, pay special attention to the vertical position of the cutting blade, otherwise the edges will turn out nervous.

• The second option is to use an electric jigsaw for wood. but it is also suitable for small amounts of work, while also the thickness of the board is limited, the marking process is similar to the above described. The work is easier to perform, because it is not necessary to apply physical force and monitor the verticality of the cut. the sole in the equipment ensures that the right angle is observed;
• Now consider how to evenly cut a board lengthwise with a circular saw. There are two variants of work: if the edges of the element are uneven, then the line for the trimmer is pre-drawn, according to which the cutting is done (most often this is done with unedged lumber), if one edge is flat, then the stop is set at a certain distance, and you just drive the tool, pressing the stop part to the end;

Sawing types of logs

Logs are sawn into boards in two basic ways:

Additional methods are also possible:

Radial Sawing. It is a type of sawing in which the axis of the cut goes through the core of the log and as a result the annual rings in the cross-section of the board form an angle of 76. 900 Lumber made with this cut has uniform color and texture. The sawn timber hardly deforms when it shrinks and does not swell when it moistens, since the dimensions of the wood change mainly by the beveling of the rings (across the fibers). In radially sawn logs, the annual rings are arranged with a thickness of. These materials are characterized by high productivity rates when compared to other types of lumber.

Tangential sawing is carried out along the tangential mowing line of the annual rings at a small distance from its core. The layers of the obtained boards are characterized by a pronounced texture and a bright wavy pattern of annual rings. Such lumber is characterized by higher shrinkage and moisture absorption rates than radial lumber. As a result, they will become very deformed when exposed to moisture. Such boards are in demand for use in dry conditions.

Rural (semi-radial) and mixed types of sawing have signs of two basic types of sawing simultaneously: radial and tangential. Therefore, they exhibit an average rate of shrinkage and swelling. Rural boards are characterized by straight lines of annual rings, which are arranged at an angle of 46. 75 degrees. To the layers. Mixed lumber is characterized by the fact that the line for trimmer mowing varies from straight at the edges (in width) of the board, to arched to the middle.

The central cut is made right in the center of the torso and contains the core. Bearing in mind the fact that the core of the trunk. Wood with low strength values, lumber that is cut in the center is characterized by a structure that is not strong in level.

How to properly saw with a wood hacksaw. Construction, repair, construction

It is impossible to imagine a professional carpenter or a carpenter without a wood hacksaw, and in everyday life it is used quite often. The widespread use of this tool has contributed to the emergence of its various types, designed for certain operations.

In order to choose a hacksaw properly, one should study its characteristics, imagine what exactly needs to be sawn with it and how often it will be used.

As with any common tool designed to do many jobs, wood hacksaws have several classifications.

By type of cut and purpose

Saws can be designed for cross-cutting, longitudinal (circular) or universal cutting. These types differ in tooth shapes.

Teeth of saws designed for longitudinal sawing of wood have a shape of oblique triangle. The angle between them is from 45 to 60°, which allows you to cut wood only in one direction, while ensuring a precise and straight line for the trimmer cut. They are most commonly used in furniture making.

Saws with teeth resembling an isosceles triangle are used for cross-cutting wood. Sharpening at an angle of 45-55° makes it possible to cut workpieces both in the forward and reverse direction. These saws cut most efficiently through dry wood.

Universal hacksaw has two types of teeth. triangular and semi-circular (with semi-circular more than triangular). As the saw moves forward, the long teeth give direction, and the wider triangular teeth widen the cut, allowing swarf and chips to escape unhindered. The smaller the angle between the teeth, the more accurate the cut.

Depending on their function, wood hacksaw blades can be classical, cupped and spiked. Gang saws are used for cutting wood lengthwise or crosswise. Hole saws are used for cutting holes. Grip saws are used to form elements for joining individual parts together.

Tooth size

Tooth size is one of the key parameters of any wood hacksaw. Sizes are defined as pitch, i.e. the distance between adjacent points. Depending on this parameter, saws can have teeth:

Hacksaws with fine toothing (2.0 to 2.5 mm).) ensure precise wood sawing and are most often used for cutting very small workpieces.

Saws with large teeth (4 to 6 mm) are used for cutting logs or beams.

Saws with medium tooth size (3,0 to 3,5 mm) are used for details with small dimensions.

There are also kinds of manual wood saws with teeth, arranged in groups of 6-7 pieces, separated from each other by gaps. This tool is used for raw wood. Gaps between the wood chips prevent them from clogging up the sawing channel.

Classification by construction

Structurally, wood hacksaws are made up of two types of saws:

Narrow hacksaw blades are used for cutting workpieces up to 10 cm thick. They are also used for pruning branches in the garden, sawing curved pieces, and other work. Structurally, these saws are narrow blades with triangular teeth connected to an L-shaped handle.

Standard hacksaw blades (GOST 2615-84) may have any type of teeth. They are often equipped with sets of interchangeable blades, designed to perform a wide variety of carpentry and joinery work.

The blades of hacksaws can bend greatly when cutting hardwood. Saws with blades equipped with a shank that serves as an additional ribbing are free from this drawback. However, its presence does not allow to make a cut deeper than the width of the blade itself.

A hacksaw with an award-winning blade looks like a planer. It has two handles and is used when grooves or clefts must be made. In this case, the depth of these elements can be different.

The beam saw is a blade stretched on a base made in the form of a large arc. It is connected to the handle with a threaded or tensioned connection, which allows you to use different types of blades during the work. In turn, this makes it possible to single-handedly perform the cutting of workpieces that have complex cutting lines.

On the market you can also find folding wood hacksaws. They are very light and small when folded, which allows fans of outdoor activities to take them with them on a hike or fishing. Such a saw has a short, pointed blade with small teeth.

Other varieties

There are other types of wood saws. Among them there are garden hand saws, equipped with a narrow blade, for the manufacture of which chromium steel is used. It has widely spaced tines that are angled toward the handle. It is convenient for those cases when the emphasis during the sawing process must be on oneself.

There is a two-handed saw that can be used to saw large logs or cut down trees. It must be operated by two people.

The chainsaw is a short, carbide-toothed chain with two handles on the ends. It is compact and suitable for camping trips. Can be operated by two or one person.

A modern and versatile tool is the electric wood sander, which can be used for a wide variety of tasks. In some cases it can be quite a substitute for a circular saw. Not only wood, but also plastic and metal can be sawed with it by changing blades.

Basic parameters

The effectiveness of a wood hacksaw depends greatly on its performance. The main ones are:

When choosing a tool, you need to pay attention to each element of the characteristic. Only in this case you will not regret the purchase.

Material of the blade

The blade of modern wood hacksaws is made of high quality tool (alloyed) steel with high m carbon and silicon (65G, 8KhF, U7U10). hardness should be no less than HRC 45. There are also some models which have a combined more wear-resistant blade with a cutting part (teeth) of higher hardness (HRC55 60).

Length and shape of the blade

On the domestic market you can find wood hacksaws in lengths from 250 to 650 mm in multiples of 25 mm. This parameter is set by GOST 2615-84 and depends on the distance between the teeth.

The teeth and their shape

saw’s capabilities depend on its shape and the size of its teeth. A large number of teeth on a certain length of blade means a fine sawing but a slow advance. Fewer teeth result in a coarser cut.

Wood consists of fibers, which separate when being sawn. They produce sawdust that needs to be removed. The shallower the teeth, the faster the kerf and cutting edge of the saw become clogged with fine sawdust or sawdust. The tines can no longer grip the full height of the wood. Sawing becomes more and more tiresome, mainly more unproductive. Large-sized tines, on the other hand, are almost never blocked, because the tips are farther apart.

Almost all saws have bifurcated teeth, i.e. their tips alternately bend left and right. The higher the pitch, the wider the kerf, the less the sawdust clogs and the less the saw jams.

Over time the saw teeth get blunt and need to be resharpened. Improper set-up has to be repaired. This is no easy task, even for an expert. That’s why we recommend to buy jigsaws with hardened teeth. They do not blunt as quickly, and are easier to sharpen than conventional saw teeth.

Simply lay the saw blade on the table and use the sharpening stone to double tap the cutting edge from top to bottom, then turn the blade upside down. The saw is sharpened and you can start sawing.

Steep teeth for a rip saw

Almost all hand saws including hacksaws and backsaws have their teeth set in this way.

Cutting edge of the teeth is vertical. Suitable for longitudinal cuts.

When sawing lengthwise the workpiece should protrude over the workbench well enough to make sawing easier.

The marking below the clearance indicates where the saw is deflected.

Circulation table

When building a table for a circular saw, the most important thing is to choose the right material. For household purposes you can build a table out of thick planks or plywood and put it in the garage. If you have to work with large amounts of materials, it is better to build the framework of a metal profile.

Any material used in the manufacture must meet the following requirements: be strong, reliable, resistant to vibration. as well as:

When setting up the table, grounding must be provided. If these conditions are not met, the circular saw, at any time can slow down because of a broken drive or a jammed disk. As a result. splinters, ruined parts, and even injuries to the operator. The circular saw blade installed in the table must not protrude more than one-third of its diameter.

For the simplest version of the table takes a sheet of plywood, cut a rectangle on which a long cut is made. On it will move the trimmer. On top of the width of the working plane of the circular saw itself screw 2 guides. They can be made of aluminum angle. Screw two stands to the plywood sheet from below. Their height should be equal to the depth of cut of the available saw model. The tool will walk on this resulting guide. From the way the guide rail is fixed, it is possible to make a precise cut at any angle. A simple table is ready.

Professionals saw parts of any shape with a circular saw, regardless of complexity. In order not to spoil the material and not to injure yourself, it is necessary to follow the rules of safety. If you listen to the advice of experienced craftsmen, properly set up the tool and arrange the workpieces to be sawn, then the output will be almost finished building material with the required parameters.

Cleverness is a good thing! However, I do not share this approach. It’s not safe. When building a skate park, we used the same homemade frame. As a result, the circular saw came out of there and started jumping around wildly on the floor. It’s a good thing no one’s feet got banged up. And turned it off we could only from the network, because the trigger had to be fixed.

Such ideas are certainly good, but I consider it my duty to warn people.

Thanks. that’s another reason I don’t remove the blade guard!. Although if for some reason it will fall out (although I can not imagine how it can do it in this design). the housing will instantly flip open, covering the diskTaking care of the wire, I screwed a hook from below. even if the saw falls out. it will hang on the wire Well, in general, I want to hang a socket with a switch below. it will not pull the plug many times out of the socket

The frame was made spontaneously, because it is quite difficult to saw straight rectangular thin bars “by hand” with a circular saw

Take the guard off the saw, it will be less clogged, you can’t see the wedging blade, I hope you didn’t take it off? I have a Makita hanging like that too, although I bought a piece of countertop and screwed the saw to a sheet of iron

No, the knife is not removedThe hood does not hinder installation or depth it just turned away, and did not notice that he clogged. the flow of air from the drive cleans it well (MakiTovsky drive moreover with slots for cooling. they further enhance the flow) Yes, and I had to write a napivki once. floors I do, in the grooves between the boards to embed

I see, my saw is just basically upside down, I remove the cover that covers the disc, there are 3 screws, and then in the upside down state is clogged and starts squeaking when the disc stops.
