How to use the circular saw guide

Fabrication instructions: circular saw guide

Circular saw guide rail. a fixture that ensures a straight cut. There are a total of two methods to help make a straight cut:

The first option involves fixing the tool on a workbench, with the workpiece moving along the guide. Quality of the cut will be high, but the size of the processed part is limited, due to the size of the machine. With the second method of machining, the parameters of the workpiece can be arbitrary. The main thing is that the crosscutting tool must be securely fixed.

Carpentry manufacturers produce a wide range of guide bars for circular saws. Parts are easy to use and comply with safety regulations. Construction drawing includes guide rail. In some cases it is possible to set the required degree of inclination of the cutter, it is possible to avoid backlash, jamming of the working element when it moves.

A factory-mounted carriage on a circular saw does a good job, but is expensive. This article shows how to assemble a saw guide bar with your own hands.

What it is?

Essentially, the guide rail is the rail that allows the handheld circular saw to slide forward and backward while keeping the tool from deviating from the cutting line. But a properly designed guide not only ensures a straight cut, it also reduces chipping where the saw and material come into contact.

Homemade guides have different designs and are made of different materials. For example:

  • plywood guide rail;
  • A guide rail made of angle bars;
  • aluminum profile rail;
  • a ruler made of a building rule;
  • outboard carriage on bearings.

The chair and outrigger carriage are the most difficult to make. A plywood guide rail or a profile rail is much easier by design, but this does not mean that a cut made with them will not be of the same quality. The difference between the varieties is mainly in their ease of use.

Additional functions of the guide rail

Such designs have a number of additional features that you should familiarize yourself with before using a homemade guide bar for a handheld circular saw:

  • Protects the material to be sawn from damage;
  • allows you to adjust the exact length of the cut;
  • speeds up the sawing process of the wood many times over;
  • clamps the wood securely to the work surface.

Step-by-step instructions

Here is a detailed process for making a simple saw guide rail.

Track marking

The slots for the slide must be clearly parallel to the circular disk. This is why you mark and trace the workpiece’s centreline with a pencil and ruler. Precise marking for good tools.

Additionally! If there is no backlash, the ruler should be pressed to the disk itself.

Milling slots for skids

When the main rail is ready, slots are made on both sides of it at an equal distance using a milling machine. Metal profiles (U-shaped) can be inserted into the slots to make the slots last longer and the runners move easily.

Making the runners

The slats are sawed from wood. Prefer hardwoods. maple, oak, etc. The slats must fit well, but not too tightly, otherwise the carriage will not be able to move. If this step is done correctly, the base of the sled will be easy to install on the work table.

For a cut at a non-standard angle, it will be necessary to additionally make a combination square

Mounting the base of the carriage on the skids

The slats are glued, then a plywood sheet is put on them. For the duration of the glue is placed on the plywood weighting agent, or it is fixed by any clamp. It is advisable to sand the plywood beforehand.

Tip! To prevent glue from leaking and getting onto the surrounding surface, the edges of the guide slats can be bound with tape.

Marking of carriage corners

The carriage is installed in the slots, and the craftsman saws the front of it. From this area 2 corners of 45 degrees are measured. After that the corners are sawed off on both sides.

Correcting the angles of the carriage

Fix the construction and make several test pieces to assess the functionality of the carriage. If the angles of the sawed slats are not right, the circular sled is corrected: its borders are trimmed. Then again a test cut must be made.

This procedure is carried out until the desired effect in the size of the cut, the vibration level, and the need to exert effort in the process.

Guide rail for circular saw: making it yourself

When using high-performance hand-held power tools, the quality of the work performed is always an issue. High quality depends largely on the professionalism of the master working with the tool. Therefore, in addition to the basic equipment of most electric circular saws, it is recommended to use additional accessories. These accessories facilitate the work and ensure high quality of work, even when operated by beginners.

The circular saw guide has many features that make working with the tool much easier. Among such important functions it is worth noting:

  • Ensuring high precision when cutting large sized material;
  • the guide allows you to ensure a correct cut with high precision;
  • When working with the device it is possible to perform not only cutting in a straight line, but also to perform work on curvilinear cuts;
  • the workpiece is easily and accurately cut in both the longitudinal and transverse directions when using the guide;
  • It is easy to machine workpieces to one standard with this fixture;
  • the device makes it possible to do the machining of several workpieces by one template;
  • Working with a guide rail provides a high degree of safety in the workplace.

Circular saw guide rail

A brand-name guide bar for a circular saw costs almost as much as the saw itself. Nevertheless, the device is very important. Why? When it is used, is it possible to do without it, can something replace it or make it yourself? The circular saw guide offers certain advantages while working. This article describes these advantages and gives answers to related questions. Here we look at how to make a guide bar with your own hands.

How to handle the circular saw

If you often have to saw large wood pieces, thick boards or boards of carpentry, you cannot do without the circular saw. But this must be handled skilfully. The slightest mistake can result in the saw blade turning too fast and cutting through the wood in the wrong way and either having to redo the job or start from scratch all over again.

Even a beginner can correctly cut a wooden workpiece with an ordinary hacksaw the first time, provided he has a steady hand and an accurate eye. These attributes are not sufficient when working with a circular saw. The saw blade is turning too fast for you to be able to readjust its advance on the workpiece at any time. Only with careful preparation for work and correct use of the circular saw can good results be expected. You also need a guide rail or guide ruler, i.e. a device that makes it possible to guide the machine precisely along the set line, without allowing it to deviate sideways.

During the preparation it is very important to choose the correct saw blade and depth of cut, both of them should correspond exactly to the structure of the material to be sawn and its thickness.

Required materials and tools

Before you start making the construction, you need to familiarize yourself with the list of necessary tools and materials:

Using a Circular Saw with a Guide Rail | Toolstop Guide

  • Wooden blanks: boards, plywood, laminate;
  • bars of wood with a thickness of 10 cm or more;
  • Self-tapping screws, screws, bolts or nuts;
  • a drill with drills;
  • Screwdrivers or an electric screwdriver.

Additional information! The above tools should be prepared in advance, so that they are at hand during the creation of the guide.

Purpose

People who have used a circular saw know how difficult it is to achieve a straight cut. Even though you try to guide the tool according to the markings, it is still trying to wiggle. If this happens, it turns out that time is wasted and the material is ruined.

Some people get out of the situation by fixing a pair of clamps on a ruler bar. But with a manual circular saw, this method is inconvenient, because the clamps catch the tool.

  • Always having to adjust the guide bar when it is in use. The tool is set with a small indentation from the cutting line, and then the blade goes exactly along the line. This method is suitable in the case of single jobs. It takes a long time to make many precise cuts.
  • The guide bar is designed so that the edge of the guide bar is exactly aligned with the cutting line. All that remains is to align the two strips and get to work.
  • High-quality bars are additionally glued with a soft tape to prevent chips in the material, such as fiberboard or laminate.
  • It is inconvenient to be able to saw and monitor the position of the rule at the same time. Overpressing or insufficient pressure will ruin the material. Circular saw with guide rail requires only moving the saw forward.
