How to Saw Reiki Hand Circular

A hand-held circular saw, which is simply called a circular saw, is a convenient tool for cutting and cutting lumber.

In the kit with it, devices are usually delivered that help the master in work.

But the same devices can be made or improved with your own hands. Yes, and work experience sooner or later will lead to the emergence of completely home-made adaptations (as they are called), which, with all the plainness, can significantly facilitate sawing and save time.

Parallel emphasis

The usual parallel emphasis for circulars is a good example of how a minor addition can be of great benefit. Almost every hand saw is equipped with a parallel stop for longitudinal cutting of a given width. This is a really useful device.

The staff emphasis has one drawback. For safety reasons, it is set to values ​​that allow cutting with a width of less than 20–25 mm. This is done so that the emphasis does not interfere with the movement of the saw blade guard. But it is enough to fasten a wooden block with screws to the parallel level of the standard stop. and its capabilities will increase, while the minimum cutting width will not be limited in any way.

Note! We must remember safety. when making cuts of less than 15 mm, the bar does not allow the protective cover to close the saw blade.

An emphasis for cross and angular cuts

The transverse cutter is also often used. With its help, cuts of boards pass quickly and precisely at an angle of 90 °. This emphasis is also used for facing boards. Its base is a 10 mm thick plywood sheet. A guide bar or rail is fixed on it with glue or self-tapping screws with a height of at least 20 mm. An emphasis perpendicular to the guide and made of the same bar is fixed on the bottom side of the base.

The excess part of the base (from the guide to the saw blade) is cut off. Since this distance is different for each model of manual circulars, the adaptation is always done individually. It is usually fixed with clamps to the processed material.

Advanced craftsmen make their mounting devices from wooden washers, one of which has the form of an eccentric. The clamp is carried out with the wing nut on the screw. Such a clamping device allows you to very quickly fix the emphasis on lumber of different widths.

If you install the same block on the other side of the guide, but fixed at an angle of 45 ° to the first, and then cut off part of the base at a angle of 45 ° with a saw, you will get an angular universal stop for cuts at both 45 ° and 90 °. A more universal design of the angular stop will be obtained in the case of ensuring the rotation of the bar. And compliance with the angle can be monitored by a protractor mounted on top. It should be noted that the manufacture of a protractor for circulars with their own hands is a more difficult task.

Saddle stop

If you have to saw a circular saw many identical bars, then it is worth spending time on the manufacture of a simple saddle stop. Its use will more than return the spent minutes. The saddle stop is especially effective when cutting thick bars, for which the disk requires two cuts from different sides.

The emphasis saddle has a U-shape. The base is a board 25 mm thick, its width is exactly equal to the thickness of the sawn timber.

Side surfaces of 10 mm plywood are attached to the base. The width of the sidewalls should be greater than the width of the beam in order to provide support to the circular platform until the saw blade comes into contact with the beam.

The saddle is put on the beam at a distance from the marking of the cut, corresponding to the working distance to the saw blade, and is pressed against the beam through the side clamps with clamps. Using a sidewall as an emphasis for a saw site, cutting is carried out. If the thickness of the beam is such that one cut is not enough, then it is turned over and another cut is made. The position of the stop does not change.

Guide rail

For cuts of large and long sheet lumber on the table, a long, self-made long guide rail for a circular saw will be useful.

The basis in this case is (8–10 mm) a plywood strip with a length exceeding the dimensions of the sheet being cut. The tire itself can be wooden (a bar 15–20 mm thick) or metal from a profile of a U-shaped section. The tire is fixed to the base with glue or screws. On one side of it should remain a narrow edge of the base, sufficient for fastening to the sheet with clamps. On the other hand, the first cut is made with a saw along the base. After that, the edge of the base will exactly coincide with the passage of the circular disk. When working, it is combined with the marking on the sheet, the emphasis is fixed and the sheet is sawed.

Edge emphasis

This is already a rather complicated device, requiring time and accuracy in manufacturing. It allows you to cut parallel to the edge of the material being cut. It will be useful to make a drawing before starting work, so as not to miss the size. In fact, such an emphasis is in the set of a circular saw, but its small length does not always ensure an even cut. The large size and the desired strength require the manufacture of the support base of plywood with a thickness of at least 15 mm. From it, you can also make a stubborn bar.

Stages of manufacturing an emphasis:

  • at the base, longitudinal grooves for the keys are made;
  • hardwood dowels are mounted on a stop bar;
  • between the longitudinal grooves, another through groove is made to fix the thrust bar during operation;
  • a hole for a circular saw blade is cut out at the base;
  • on the sides of the base are placed restrictive straps for installing the circular and clamps are provided for its reliable fastening.

When the emphasis is installed on the material to be processed, the stop bar moves in the grooves of the base to the desired distance and is secured through the through slot with a thumbscrew. In order not to suffer each time with a ruler, you can fix it (or a piece of roulette) on the basis of the stop along the guide grooves.

Useful Tricks and Tips

There are such small devices that even a shameful tool to consider. At the same time, they help a lot when cutting. These are tricks of experienced masters.

Blank template

When cutting a large number of identical parts, you can use the first of them as a template for cutting subsequent copies. It is only necessary on one side of the first sample to fix the thrust piece with a width corresponding to the distance from the edge of the plate to the cutting disc. By installing such a template on the material being cut, many identical parts can be made without marking.

Adjusting bars

The simplest part that facilitates the installation of any emphasis and the guide along the marking is a small section bar. Cuttings are applied on it, the distance between which is equal to the segment from the end of the sole of the saw to the saw blade. Two of these bars will help to establish any guides quickly and accurately on the required indent from the marking line. It remains only to fix the guide.

Material tear protection

Protection can be any bar, the width corresponding to the thickness of the cut workpiece. If it is fixed at the place where the saw blade exits from the material being processed, it will act as a limiter and will serve as protection against tearing and chips.

These devices are not limited to a set of useful homemade products that facilitate the work with a hand saw. These are the easiest to manufacture. Others take time and skills. But craftsmen even make such a device as a protractor for circulars with their own hands. It would be a desire.

Parallel emphasis is an important tool when working with a circular saw. This device serves to perform cuts parallel to the plane of the saw blade and the edge of the processed material. Usually, one of the options for this device is supplied with the circular saw by the manufacturer. However, the manufacturer’s option is not always convenient to use and in most cases does not satisfy the needs of the consumer. Therefore, in practice, you have to do with your own hands one of the options for this device according to simple drawings.

There are several options for a constructive solution to this seemingly simple task. All options have their advantages and disadvantages. Choosing a suitable design should be based on the needs that arise when processing various materials on a circular saw. Consequently, the choice of the right solution must be taken seriously, responsibly and creatively.

This article discusses two of the simplest design solutions for creating an angular parallel stop for a circular saw with your own hands according to the available drawings.

How to Saw Reiki Hand Circular

Features

Common to these design decisions is the rail moving relative to the cutting disk along the plane of the saw table. When creating this rail, it is proposed to use a typical extruded profile of a rectangular unequally angular angular cross section of aluminum or magnesium alloys. When assembling a parallel angular stop with your own hands, other profiles of a similar section can be used in accordance with the length and width of the working plane of the table, as well as the circular marks.

In the proposed drawings, a corner is used with the following dimensions (mm):

First performance

A rail is taken from the corner mentioned above with a length of 450 mm. For proper marking, this workpiece is placed on the circular work table so that the wide bar is parallel to the saw blade. The narrow bar should be on the desktop from the side opposite to the disk, as shown in the figure. In a narrow shelf (41 mm wide) of the corner at a distance of 20 mm from the end, the centers of three through holes with a diameter of 8 mm are marked, the distances between them should be the same. At a distance of 268 mm from the line of location of the marked centers, a line of centers of the centers of three more through holes with a diameter of 8 mm (with the same distance between them) is noted. This marks the markup.

After that, you can proceed directly to the assembly.

  1. 6 marked holes with a diameter of 8 mm are drilled, burrs, which are inevitably created when drilling, are processed with a file or sandpaper.
  2. Two 8×18 mm pins are pressed into the extreme holes of each triple.
  3. The resulting design is placed on the desktop so that the pins fit into the grooves provided for by the design of the circular saw table, on both sides of the saw blade perpendicular to its plane, a narrow angle bar is located on the plane of the desktop. The whole device moves freely on the table surface parallel to the plane of the sawing disk, the pins act as guides, prevent skewing of the stop and violation of the parallelism of the planes of the circular disk and the vertical surface of the stop.
  4. From the bottom of the working table, M8 bolts are inserted into the grooves and middle holes between the stop pins so that their threaded part fits into the slot of the table and the rack holes, and the bolt heads rest on the bottom surface of the table and are between the pins.
  5. On each side, over the rail, which is a parallel emphasis, a wing nut or an ordinary nut M8 is screwed onto the M8 bolt. Thus, rigid fastening of the entire structure to the desktop is achieved.

Operating procedure:

  • both wing nuts are released;
  • the rail moves to the required distance from the disk;
  • fix the rail with nuts.

The rail moves parallel to the working disk, since the pins, acting as guides, prevent distortions of the parallel stop relative to the saw blade.

This design can be used only if there are grooves (slots) on the desktop of the circular saw on both sides of the disk perpendicular to its plane.

The second constructive solution

The construction solution of a parallel emphasis for a circular saw, created by yourself, below, is suitable for any desktop: with or without grooves on it. The sizes proposed in the drawings relate to a particular type of circular saw, can be proportionally changed depending on the table parameters and the brand of the circular.

In accordance with the drawing below, two guides are made of metal. For this, a steel equal-angle bracket with a size of 20×20 mm is taken. Turned and trimmed in accordance with the dimensions of the drawing. On the larger bar of each guide, two holes with a diameter of 5 mm are marked and drilled: in the upper part of the guides and one more in the middle in the bottom for the M5 thread. A thread is cut in the threaded holes with a tap.

The guides are ready, and they are attached to both ends with M5x25 bolts with a cylindrical head for a hexagon or standard M5x25 bolts with a hexagonal head. M5x25 screws with any head are screwed into the threaded guide holes.

Operating procedure:

  • the screws in the threaded holes of the end rails are loosened;
  • the rail moves from the corner to the cut size required for work;
  • by tightening the screws in the threaded holes of the end guides, the selected position is fixed.

The movement of the emphasis rail occurs along the end planes of the table perpendicular to the plane of the saw blade. The guides on the ends of the corner of the parallel stop allow you to move it without distortions relative to the saw blade.

For visual control of the position of the home-made parallel emphasis on the plane of the circular table, a marking is drawn.

How to Saw Reiki Hand Circular

Without a circular saw, it is difficult to imagine a carpentry workshop, since the most basic and common operation is precisely the longitudinal sawing of workpieces. About 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 the cutting 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 complex element. a parallel emphasis.

How to Saw Reiki Hand Circular

So, the parallel emphasis is the movable part of the machine, which is the guide for the workpiece and the workpiece moves along it. Accordingly, the quality of the cut depends on the parallel stop, because if the emphasis is not parallel, then it is possible to jam the workpiece or the saw curve.

In addition, the parallel emphasis of the circular saw should be a fairly rigid structure, since the master makes efforts by pressing the workpiece against the emphasis, and if displacements of the emphasis are possible, this will lead to parallelism with the consequences indicated above.

How to Saw Reiki Hand Circular

There are various designs of parallel stops depending on the methods of attaching it to a circular table. We give a table with the characteristics of these options.

In this article, we will analyze the option of creating a design for a parallel stop for a circular with one mounting point.

Preparation for work

Before starting work, it is necessary to determine the necessary set of tools and materials that will be needed in the process.

The following tools will be used for work:

  1. Circular saw or jigsaw can be used.
  2. Screwdriver.
  3. Grinding machine.
  4. angle grinder (Angle grinder).
  5. Jigsaw.
  6. Hand tools: hammer, pencil, square.

In the process, you will also need the following materials:

  1. Chipboard.
  2. Plywood.
  3. Solid pine.
  4. Steel tube with an inner diameter of 6-10 mm.
  5. Steel rod with an outer diameter of 6-10 mm.
  6. Two washers with an increased area and an inner diameter of 6-10 mm.
  7. Self-tapping screws.
  8. Joiner’s glue.

Circular stop design

The whole structure consists of two main parts. longitudinal and transverse (meaning. relative to the plane of the saw blade). Each of these parts is rigidly connected with the other and is a complex structure that includes a set of parts.

How to Saw Reiki Hand Circular

The main technological solution of this emphasis is the principle of jamming with an eccentric and tight pressing of two transverse guides with an oblique end face.

How to Saw Reiki Hand Circular

Fixation occurs by turning the eccentric mechanism.

How to Saw Reiki Hand Circular

The pressing force is large enough to ensure the strength of the structure and securely fix the entire parallel emphasis.

The whole structure is not trivial and consists of a large number of different parts, each of which has its own purpose and size.

From a different angle.

How to Saw Reiki Hand Circular

The general composition of all parts is as follows:

  1. Transverse part
  • The base of the transverse part;
  • Upper transverse clamping plate (with an oblique end face);
  • Lower transverse clamping plate (with an oblique end face);
  • End (fixing) level of the transverse part.
  1. Longitudinal part
  • Plane sliding element (chipboard, 2 pcs.);
  • The base of the longitudinal part;
  1. Clamp
  • Eccentric
  • Cam handle

Making circular

Blank preparation

It all starts with the fact that it is necessary to cut the workpieces to the specified sizes.

How to Saw Reiki Hand Circular

There are a couple of points to note:

  • planar longitudinal elements are made of chipboard, and not of solid pine, like other parts.
  • Two blanks of clamping strips are made with “oblique” ends (not 90º, but 63.5º).

How to Saw Reiki Hand Circular

Thus, we obtain the following set of blanks.

How to Saw Reiki Hand Circular

Eccentric clamp

We proceed to the manufacture of an eccentric clamp, which rigidly fixes the guide.

How to Saw Reiki Hand Circular

Two workpieces, 80×80 mm in size, are glued together.

How to Saw Reiki Hand Circular

Press with a clamp and let the glue dry. In toga it turns out such a blank.

How to Saw Reiki Hand Circular

With a 22 mm pen drill, we drill a hole in the end under the handle.

How to Saw Reiki Hand Circular

In the center of the workpiece, you need to make a blind (not through hole) 5 mm long.

It is better to do this with the help of drilling, but you can simply fill with a nail.

How to Saw Reiki Hand Circular

The circular saw used for work uses a home-made movable carriage made of chipboard (or, alternatively, you can make a raised table “whip up”), which is not very bad to deform or spoil. In this carriage, we nail a nail into a marked place and bite off the hat.

How to Saw Reiki Hand Circular

Thus, an improvised axis of rotation of our part, called the "eccentric," was obtained (although in this case, the stuffed hole is located strictly in the geometric center).

How to Saw Reiki Hand Circular

Then, dressing the workpiece on an axis made of a nail, we begin to grind corners and excess material.

How to Saw Reiki Hand Circular

As a result, we get an even cylindrical workpiece that needs to be processed with a tape or eccentric sander.

How to Saw Reiki Hand Circular

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

How to Saw Reiki Hand Circular

The transverse part of the guide

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

  • The base of the transverse part;
  • Upper transverse clamping plate (with an oblique end face);
  • Lower transverse clamping plate (with an oblique end face);
  • End (fixing) level of the transverse part.

Upper transverse pressure plate

Both clamping strips. the upper and lower have one end not straight 90º, but inclined (“oblique”) with an angle of 26.5º (to be precise, 63.5 º). We have already observed these angles when sawing blanks.

How to Saw Reiki Hand Circular

The upper transverse pressure plate serves to move along the base and further fix the guide by pressing it against the lower transverse pressure plate. It is assembled from two blanks.

How to Saw Reiki Hand Circular

They are going to glue.

How to Saw Reiki Hand Circular

And additionally fixed with screws.

How to Saw Reiki Hand Circular

Lower transverse pressure plate

The lower transverse pressure plate is rigidly fixed to the base and serves to fix the guide by pressing it against the upper transverse pressure plate.

How to Saw Reiki Hand Circular

Like the upper bar, it also consists of two blanks.

How to Saw Reiki Hand Circular

We also collect on glue and screws.

How to Saw Reiki Hand Circular

Both pressure bars are ready. It is necessary to check the ride and remove all defects that interfere with smooth sliding, in addition, you need to check the tightness of the inclined edges; there should be no gaps or crevices.

With a snug fit, the strength of the connection (fixing the guide) will be maximum.

How to Saw Reiki Hand Circular

Assembly of the transverse entire part

The transverse stop bar of the transverse rail is directly fixed to the circular table.

How to Saw Reiki Hand Circular

A transverse base is attached to this strap.

How to Saw Reiki Hand Circular

We assemble the entire structure for glue and screws.

How to Saw Reiki Hand Circular

The longitudinal part of the guide

The entire longitudinal part consists of:

  • Plane sliding element (chipboard, 2 pcs.);
  • The base of the longitudinal part.

Plane Slide

This element is made of chipboard in that the surface is laminated and smoother. this reduces friction (improves sliding), and also more dense and strong. more durable.

How to Saw Reiki Hand Circular

At the stage of forming blanks, we already sawed them in size, it remains only to refine the edges. This is done using edge banding.

How to Saw Reiki Hand Circular

The technology of chipping chipboard is simple (you can even stick it with an iron!) And is understandable.

The base of the longitudinal part

The base consists of four longitudinal elements, as well as two vertical ones for mounting an eccentric.

How to Saw Reiki Hand Circular

If you expand on the details, you get such a scheme.

How to Saw Reiki Hand Circular

We collect previously sawn blanks on glue.

How to Saw Reiki Hand Circular

And also additionally fix with screws. Do not forget to observe an angle of 90º between longitudinal and vertical elements.

How to Saw Reiki Hand Circular

Assembly of the transverse and longitudinal parts.

First you need to mount the substrate (longitudinal element) with the upper transverse clamping bar.

How to Saw Reiki Hand Circular

We fix on glue and self-tapping screws.

How to Saw Reiki Hand Circular

Right here HIGHLY. it is important to observe an angle of 90º, since it is from him that the parallelism of the guide with the plane of the saw blade will depend.

Then we install a longitudinal base on the substrate.

How to Saw Reiki Hand Circular

Also fix on glue and screws.

How to Saw Reiki Hand Circular

Cam installation

An eccentric is installed between two vertical elements on the longitudinal part.

How to Saw Reiki Hand Circular

In the eccentric itself, you need to place a metal tube (future sleeve) with an inner diameter of 6-10 mm.

How to Saw Reiki Hand Circular

We fix it on glue.

How to Saw Reiki Hand Circular

In addition to the bushings on the eccentric itself, you need to make similar bushings on the vertical elements, although, as an option (worst), you can use larger washers.

How to Saw Reiki Hand Circular

Additionally, a thrust block should be installed for a better clamp.

How to Saw Reiki Hand Circular

Guide Installation

The time has come to fix our entire structure on a circular machine. To do this, attach the crosscut bar to the circular table. Fastening, as elsewhere, is carried out on glue and screws.

How to Saw Reiki Hand Circular

Install the moving part.

How to Saw Reiki Hand Circular

It remains only to verify the accuracy of the corners, and we consider the work completed.
