Parallel focus for circular do it yourself. Circular to do it with your own hands: drawings, video, description Homemade parallel focus for the mill and circular

Disk saw is most often used for accurate, smooth sawing Woods I. wood materialsBut it can also be useful for trimming light metals and plastic. She should have a circular saw guide: a tire and carriage, parallel emphasis. Buying a tool, worth paying attention to this attention. Power and the number of revolutions per minute - labor productivity, quality of work, the ability to saw solid materials depends on these parameters.

Homemade desktop mini-sower

Circular hand saw - mandatory tool In the domestic master of self-respecting owner. For successful work It must have a guide tire for a circular saw. Considerable meaning of saw disks, the quality and sharpness of the cutting depends on their thickness and size of the teeth. The less tooth, the cleaner will be the surface that is processed.

Well equipped workshop has a manual electric tool that has a guide bus for disc saw, with your own hands made and configured for successful work. As well as a special connection for vacuum cleaners and bags or sawdust containers. This is very practical solutionbecause when long sawing does not have to stop every minute to remove workplace. Such a saw is manufactured by Bosch for professionals. In addition, it has the ability to adjust the angle of deviation from the vertical and the depth of the cutting.

Correct tool selection

Before buying, you should make sure that the selected tool provides the necessary cutting depth vertically and at an angle. An additional aspect that can facilitate normal operation is the length of the cable. If the conditions are not favorable to use the extension, you should select a saw with a long cable.

The proposed saws of the known manufacturers are equipped with a device for easy disk replacement, which further simplifies work. This is an excellent electric tool that can be used with small repair work Houses or in the garden.

For those people who like to make, this mechanism is simply necessary. Thanks to its small sizes, he always has a place even in a small domestic workshop.

Multifunction tool fixtures

Beginner masters doubt that with the help of manual mechanical tool You can make a cut in a straight line. It is true if you cut on the markup, but you can easily facilitate the work, applying a purchase or homemade guide device,

Manual woodworking tools, especially modern design, sometimes affect the number of auxiliary devices that help in performing the sawing material. The simplest an auxiliary device is an ordinary focus on the base of the saw with the line pointer, which will be broken.

The most popular addition is short guide with adjustable extension length. More complex designs have another roller on such a guide so that the movement of the saw is in contact with the edge of the material.

Sometimes they put indicators showing laser cutting lines and other devices that have the same disadvantages. All these mechanisms serve for information that the saw blade went out of the cut line. All simple mechanisms indicate the inaccuracy of sawing.

Why then all these systems that do not allow an amateur to perform a simple incision? Where is the error of this approach? All known woodworking machines for professional wood processing have a parallel clamping device for the constant clamping of the material being processed and a rigid lock. Often this emphasis moves. For professional instruments On sale there is a guide tire for a manual circular saw intercol, which can be applied to another overhead mechanism.

Then the tremor in the muscles of the forearm does not affect the direction of the cut, because it is controlled by a hard focus. Someone will say that surgeons do not use stops and know how to make complex and accurate operations. Probably and it is, but they have more susceptible to mechanical processing, And perfect straight lines do not matter.

To reduce the cost of purchasing a guide tire for a circular saw, you can make it with your own hands. Thanks to this homemade, the only thing that will need to be worried about the cutting process is to reliably press the saw until it stops and slowly move it forward. Materials required for manufacture, devices will be found in each workshop.

For example, a panel from thick-layer plywood width should be greater than the width of the base of the saw, for five centimeters. Length depends on the billets that will have to cut. Optimal dimensions:

• length is about 1 meter;
• width - 50 cm.

The stubborn bar must be the same length as the length of the guide device. The width must ensure reliable gluing with the surface of the panel - at least 3 cm or even much wider. The height of the plank is not less than 12 mm. Optimal size Stop: 100 cm x 3 cm x 1.5 cm.

One comment when choosing a rail in a supermarket - it should have one thin side of the smooth. How to check it? Put the rail to a smooth table and check if there is no bulge or gap. It is this smooth surface Rake will provide a straight line of cutting.

When all materials are collected, you can start making a parallel stop for the circular saw with your own hands. First you need to measure the distance between the saw and the edge of the panel in the direction of its long part. To the resulting result, add some 3 cm. This size will serve for the axial line removed from the edge of 2 cm.

Then measure the width of the base of the saw and draw the second line. This size is needed to highlight the sawing area. The space between the lines indicate the pencil so that it does not cause doubt that this area is turned off from work and is intended only for the movement of the saw. When all sizes are stacked, start mounting the rails:

1. Wash the rail glue and attach along the second line intended for the stop.
2. Press the clamp to ensure reliable gluing.
3. Leave for 12 hours so that the glue screamed complete strength.

When everything is securely fixed, you need to calibrate the device by making the first cut. To do this, set the saw until it stops, trying to make the edge of the saw base be evenly pressed to the bar and smooth movement along the tire to perform the cut. It is this first section on a thrust guide that allows you to calibrate the device for further work.

When the focus is ready, you can safely use it to get a quick cut. On the material that needs to be cut, mark the cut line. Along this line, lay a new guide so that the working edge lay on the line - the saw will cut the material exactly in this place.

Carefully setting and making sure that there are no countertops from the other side of the material cut, the saw closely press to the eagle and moving along the guide, cut off the required material size. During the sawing, you need to slightly press the saw to the device and to the surface of the stop - this will provide a straight cut. It is necessary to move it smoothly and evenly. As a result, it turns out a flat cut line. When using a device for manual circular saws, it is worth noting two interesting facts:

In the domestic workshop of the joiner there is always a place for a homemade tracing saw from manual Circular. For its manufacture, you need to have a homemade guide line and carriage for circular saw.

For the manufacture of the ruler It will take several pieces of twelve-millimeter plywood and a metal profile of 10x20 millimeters. Lenelle length - 1.5 meters. Using the cutter with a diameter of 20 millimeters, the grooves for installing the profile for the entire length of the device. The profile is fixed by screws. In parallel, the profile lines at a distance of 12 centimeters are fixed by the rib of rigidity.

Next is made by a carriage for circular with your own hands from the same plywood. The size of the carriage is arbitrary and taken under the base of the saw. The carriage made a groove for the profile installed on the line. The basic sizes are selected in such a way that the carriages lay on the profile and ended in the ribbiness. In addition to the groove, in the carriage there is a slot for exit saw Disc.

Circular saw guide - Very simple, but reliably working device. In order to cut the sheets of the material, you need to drink the saw in the carriage with two screws, attach the guide to the material, aligning the saw blade with the cut line, turn on the saw and, moving the carriage via the ruler, cut off the desired workpiece.

The manufactured device can be done universal and apply it both with an ordinary manual and submersible saw. To do this, it is enough to remove from the line profile pipe And install a moving rail to which the saw is attached. For smooth movement of the rail, the grooves must be fine with paraffin.

Cutting lumber at an angle

To cut the material at different angles, you need to have a special device for the sawing mechanism. If there is no possibility to buy such a device, you need to think about how to make homemade fantasy saw. From a simple circular, applying affordable materials. In order for this device to have an angular emphasis, you need to have two structural nodes.

The first node is a rotary device. You can collect it from waste. To do this, you will need a slab size 100x50x2 cm for the base. To the base attached to the axis rotary table In the form of a semicircular with an angular markup - the so-called transporter for circular with their own hands.

The second knot is the saw desk. Its size is 100x25x2 cm. The saw table is made a rectangular hole for the output of the saw blade and the groove for the mobile rail, to which the saw is attached. The principle of work is as follows:

Electrolovka as a sawmill

Electric jigsaw may well replace the electric saw when sawing a small amount of sawn timer and small sizes blanks. To do this, make a guide for jigsaw with your own hands. The device is simple, even a novice master will be able to make it.

From the board with a length of 800 and a thickness of 20 millimeters to make a guide for the base of the jigsaw. To do this, at the edges of the board, attach two railings 10x10 millimeters on the screws. The distance between the slats is equal to the width of the base of the jigsaw. At the ends of the boards, strengthen the rails with a length equal to the width of the working part and a height of 10 millimeters. In these rails, drill one hole with a diameter of 8 millimeters for fixing spills.

Make a table with a size of 800x400x80 millimeters. For this K. plate chipboard At the perimeter to attach 60x20 millimeters rails. Install on it two pins M8 at the edges of the table length. They will be put on and fixed by the guide. In the center of the central axis, cut through the slot to exit the pubsik peck. To do additional window 120х40 mm for the output of the peel at the corner cutting material.

On the table to make a graduation with the help of the transport, noting an angle of 90 and 45 degrees. By markup, install a rotary resistant ruler. Device is ready and can be used in operation. To do this, it must be installed on the joiner's workbench.

Homemade universal slider

For all listed guides, one universal slider can be made, which will suit any device. The slider consists of metal profile and carriages on bearings.

This design consisting of homemade guides on bearings is very convenient: simple in the manufacture, convenient in operation, it will be suitable for any guide device. The carriage has eight bearings: four stubborn and as much lateral to fix the carriage on the tire. As a tire, a profile rail guide is used. Rail guides are particularly accurate, so they are used in the manufacture of furniture.

Without a circular saw, it is difficult to imagine a joinery workshop, since the most basic and common operation is precisely longitudinal sawing blanks. On how to make a homemade circular saw and will be discussed in this article.

Introduction

The machine consists of three main structural elements:

• base;
• sawing table;
• parallel emphasis.

The base and sawing table itself are not very complex structural elements. Their design is obvious and not so complicated. Therefore, in this article we will consider the most difficult element - parallel emphasis.

So, parallel focus is the moving part of the machine, which is a guiltle guide and precisely along it moves. Accordingly, the quality of the cut is dependent on the fact that if the focus is not parallel, it is possible or encouraging a blank or a saw curve.

In addition, the parallel stop of the circular saw should be a rather rigid design, since the wizard makes an effort, pressing the workpiece to the elimination, and if the stop displacements will be possible, this will lead to non-parallelism with the consequences specified above.

Exist various designs parallel stops depending on the techniques of its attachment to circular table. We give a table with the characteristics of these options.

Design of parallel stop	Advantages and disadvantages
Fastening at two points (front and rear)	Advantages: · Pretty rigid design, · allows you to stop the focus to any place of the circular table (left or right of the saw disk); · Does not require the massiveness of the most guide Failure: · To attach the master, you need to make a clamp of one end in front of the machine, as well as bypass the machine around and consolidate the opposite end of the stop. This is very uncomfortable when selecting the desired position of the stop and with frequently reference, is a significant disadvantage.
Mounting at one point (front)	Advantages: · Less rigid design than when attaching the stop at two points, · allows you to put the stop in any place of the circular table (left or right of the saw disk); · To change the position of the stop, it is enough to fix it on one side of the machine, where the master is located during the sawing. Failure: · The design of the stop must be massive to provide the necessary stiffness of the structure.
Circular Table Molding	Advantages: · Fast set. Failure: · Construction complexity, · Weakening of the circular table design, · Fixed position from the saw blade line, · rather complex design for independent manufacture, especially from wood (made only from metal).

In this article we will analyze the embodiment of the design of the parallel stop for the circular with one point of attachment.

Preparation for work

Before proceeding with the work, it is necessary to determine the necessary set of tools and materials that will be needed during the work.

The following tools will be used to work:

1. Circular saw or can be used.
2. Screwdriver.
3. Bulgarian (corner grinding machine).
4. Hand tool: hammer, pencil, square.

During the work, the following materials will also be needed:

1. Plywood.
2. Massive pine.
3. Steel tube S. inner diameter 6-10 mm.
4. Steel rod with an outer diameter of 6-10 mm.
5. Two washers with an increased area and an inner diameter of 6-10 mm.
6. Saws.
7. Carpentry glue.

Circular Stop Design

The whole design consists of two main parts - longitudinal and transverse (meaning - relative to the plane of the saw disk). Each of these parts is rigidly connected to the other and is complex designwhich includes a set of details.

Pressing force is large enough to ensure the strength of the design and securely fix the entire parallel focus.

From another angle.

The total composition of all parts is as follows:

• The base of the transverse part;

1. Longitudinal part

, 2 pcs.);
• Base of the longitudinal part;

1. Clip

• Eccentric handcoat

Circular production

Preparation of blanks

It should be noted a couple of moments:

• plane longitudinal elements are made from, and not from the pine massif, like other details.

On 22 mm drills a hole in the end under the handle.

It is better to do this with drilling, but you can just fill the nail.

In the circular saw used to work, a homemade mobile carriage from (or as an option can be done "on skouring hand»False table), which is not very sorry to deform or spoil. To this carriage in the marked place, you smash the nail and bite the hat.

As a result, we obtain a smooth cylindrical workpiece that needs to be treated with a tape or eccentric grinder.

We make a handle - this is a cylinder with a diameter of 22 mm and a length of 120-200 mm. Then we glue it into eccentric.

Cross part of the guide

We proceed to the manufacture of the transverse part of the guide. It consists, as mentioned above from the following details:

• The base of the transverse part;
• Top transverse clamping plank (with oblique end);
• Lower transverse clamping bar (with oblique end);
• Facial (fixing) cross-piece plank.

Top transverse clamping plank

Both putting planks - The upper and lower have one ends not direct 90º, but an inclined ("oblique") with an angle of 26.5º (if you are accurate, then 63.5 º). We have already observed these corners when sawing blanks.

The upper transverse clamping bar serves to move on the base and further fixation of the guide pressed to the lower transverse pressure plate. She is going out of two billets.

Both presses are ready. You need to check the smoothness of the stroke and remove all defects that interfering with even slipping, in addition, you need to check the density of the adjacent edges; Gaps and cracks should not be.

With a dense fit, the strength of the connection (fixation of the guide) will be maximum.

Machion of the transverse

Longitudinal part of the guide

The whole longitudinal part consists of:

, 2 pcs.);
• The base of the longitudinal part.

This element is due to the fact that the surface is laminated and smoother - it reduces friction (improves gliding), as well as more dense and durable - more durable.

At the stage of formation of the billets, we have already written them into size, it remains only to reflect edges. This is done with the help of the edge ribbon.

Additional technology is simple (you can even glue the iron!) And understandable.

The base of the longitudinal part

And also additionally fix the self-pressing. Do not forget to observe the angle of 90º between the longitudinal and vertical elements.

Assembling transverse and longitudinal parts.

Right here HIGHLY!!! It is important to observe an angle of 90º, since it is precisely from it that the parallelism of the guide with the plane of the saw blade will be dependent.

Installation of eccentric

Installation guide

It's time to consolidate the whole of our design on circular Machine. To do this, attach the bar of the transverse stop to the circular table. Fastening, as elsewhere, we carry out on glue and screws.

... And we consider the work done - the circular saw with their own hands is ready.

Video

The video for which this material was was done.

Parallel focusing for circular saws can be made by one of the options on the proposed drawings.

What is common in the homemade guide - This is the basis moving along the plane of the table relative to the saw blade, which is made of standard aluminum rolled (the profile of a pressed rectangular inequaline corner cross section from aluminum and magnesium alloys, profile number - 411158)

The size of the shelves of the used corner in section (mm):

Length - 70, thickness - 6
Width - 41, thickness - 10

Performance first

The length of the corner is 450 (mm). In a wide shelf, the corner is drilled on both sides of three through holes with a diameter of eight millimeters, with the same step between the centers. In extreme holes, press two pins 8x18.

Between the pins, the bottom of the table, the bolt M8 is inserted so that its threaded part passes into the groove, and the bolt head rested into the lower plane of the table.

On top of the table, a bolt M8, clamped with a lamb nut M8 or ordinary.

How does a parallel stop for a circular saw?

1. We release both lamb nuts.
2.
3. Press the lamb nuts.

Movement of the corner is carried out in the direction of the grooves. The pins are the guides of the stop and allow you to move it relative to the saw disk without distortion (parallel).

Second execution

The length of the corner is 700 (mm). At the edges of the corner, in the ends, drill holes for the thread M5 and apply it. According to the drawing, we produce two guides from the metal.

We attach them to the ends of the corner with screws with a cylindrical head under the hexagon (M5x25 GOST 11738-84). In the threads will lead the screws M5.

How does the parallel focus work for the circular saw of the proposed option?

1. Let's let go of lamb.
2. Move the corner B. right direction relative to the saw disk.
3. Push the sheath screws.

The movement of the corner is carried out in the direction of the end surfaces of the table. The guides attached from the ends of the corner make it possible to move it relative to the saw disk without distortion (in parallel).

On the table surface, we draw markup (ruler) for visual fixation of the position of the self-made guide.

In the next article, let us dwell in more detail on the working body (saw blade) and electric.

Parallel focus is an important adaptation when working with a circular saw. This device serves to perform the cuts parallel to the plane of the cutting disk saw and the edge of the material being processed. Usually, in a set with a circular saw, the manufacturer comes one of the variants of this device. However, the manufacturer's option is not always convenient for use and in most cases does not satisfy the consumer requests. Therefore, in practice, you have to do one of the options for this device for easy drawings.

There are several options for a constructive solution to this simple, at first glance, tasks. All options have their advantages and disadvantages. Select the appropriate design follows from those needs that occur during processing different materials on circular saw. Consequently, the choice of the desired decision should be taken seriously, responsibly and creatively.

This article discusses two simplest design solutions Creating an angular parallel stop for circular saw own hands According to available drawings.

Features

Common for these design solutions is a rail moving relative to the cutting disk on the plane of the saw desktop. When creating this rail, it is proposed to use a typical pressed profile of a rectangular unevenly polished corner cross section of aluminum or magnesium alloys. When assembling a parallel corner stop, other profiles of this section can be used with their own hands in accordance with the length and width of the table working plane, as well as the circular brand.

In the proposed designs, the drawings use the corner with the following dimensions (mm):

• wide - 70x6;
• narrow - 41x10.

Performance first

Reika is taken from the above-mentioned corner of 450 mm. For proper marking, this billet is placed on the working table of the circular so that the wide plank is parallel cutting disc saws. A narrow bar must be on the desktop with the opposite side of the disk, as shown in the figure. IN narrow shelf (41 mm wide) A corner at a distance of 20 mm from the end there are centers of three through holes with a diameter of 8 mm, the distances between them should be the same. From the line of the location of the laid centers, the line of the centers of three more through holes with a diameter of 8 mm (with the same distance between them) is observed at a distance of 268 mm. On this markup ends.

After that, you can proceed directly to the assembly.

1. 6 laid holes with a diameter of 8 mm, proper or emery paper Borrowers are processed, which are inevitably created when drilling.
2. In the extreme holes of each triple, two pins 8x18 mm are pressed.
3. The resulting design is mounted on the desktop so that the pins are entered into the grooves provided by the circular saw table design, on both sides of the saw disk perpendicular to its plane, the narrow bar of the corner is located on the plane of the desktop. All device freely moves along the surface of the table in parallel to the plane of the saw disc, the pins perform the roles of guides, prevent the stop of the stop and a violation of the parallelism of the circular disk planes and the vertical surface of the stop.
4. The bottom of the desktop in the grooves and the middle holes between the pins of the stop are inserted M8 bolts so that their threaded part joys into the slot of the table and the rail holes, and the bolt heads left into the lower surface of the table and was between the pins.
5. On each side, on top of the rail, which is a parallel emphasis, a barish or ordinary nut M8 is screwed to the M8 bolt. Thus achieved hard fastening Whole design to the desktop.

Operating procedure:

• both lamb nuts are released;
• rake moves to the desired distance from the disk;
• fix rack nuts.

The rail moves parallel to the working disc, as the pins, performing the role of guides, prevent the parallel stops from the parallel resistance relative to the saw disk.

This design can only be used if there is a circular saw of the groove on the desktop on both sides of the disk perpendicular to its plane.

Second constructive solution

The proposed below constructive solution Parallel stop for the circular saw, created with their own hands, is suitable for any desktop: with grooves on it or without them. The sizes offered in the drawings relate to a specific type. circular sawscan be proportionally changed depending on the table parameters and the circular brand.

The rail is harvested with a length of 700 mm from the corner specified at the beginning. At both ends of the corner, in the ends, the two holes for the M5 thread are drilled. In each hole, a special tool (tank) is cut into a thread.

In accordance with the drawing shown below, two guides are made from metal.For this, a steel equalone corner is taken with a size of 20x20 mm. Calculate and cut in accordance with the size of the drawing. On a larger bar, each guide is placed and two holes with a diameter of 5 mm are placed: at the top of the guides and one more in the middle of the bottom under the thread M5. IN threaded holes A thread is cut into the tack.

Guides are ready, and they are attached to both ends M5X25 bolts with a cylindrical head under the hexagon or standard M5X25 bolts with a hexagon head. In the holes of the carving guides, the M5X25 screws are screwed with any head.
