How to Use a Circular Saw

 A circular saw is an essential tool and valuable addition to any DIYer's toolkit. Its most popular use is to cut long, straight lines on lumber. Understanding its internal parts makes using a circular saw much more comfortable.

Trigger lock switch: A safety feature prevents the circular saw from being accidentally turned on when the trigger is inadvertently squeezed. This switch ensures that no one else can start the saw while it is running. Lock-out switch: It prevents accidental turning on of the table saw when the door is left open after you have finished with your work. A lock-out switch is provided in case of an unexpected shutdown, which blocks the machine from turning off by itself. This is very convenient if you are working on the project and have finished with everything but need to wait for the machine to cool down.

Drive shaft: The drive shaft of a circular saw contains the motor, which propels the blade along the table saw's length. Dowel: The cylindrical part of the blade that connects the blade to the motor. This also holds the teeth of the blade and provides the cutting angle.

Table Saw Blades: All good quality circular saws come with carbon steel blades. Carbon steel is rust proof and is highly resistant to corrosion. It also provides good strength, tensile strength, and ultimate cut strength. If you are looking for the best circular saws, it is advisable to go in for high carbon steel table saw blades.

Jiggers: A jigsaw is the other important factor in learning how to use a circular saw. A jigsaw cuts a pattern and is used to cut shapes. In this case, it performs two important functions. Firstly, it helps in cutting various shapes. Secondly, it helps in cutting large pieces into smaller pieces.

Wood Shaft: A wood shank or blade is fixed into the base of the saw. Wood shanks come in various styles. The common ones include mortise and tenon, crosscut and mitred shanks. Mitred shanks are steeper and deeper than the other kinds of wood shanks.

Electric Brake System: An electric brake system helps counteract the blade's force when it is being pulled or pushed. Electric brake systems can be fitted on the saw as a separate device or can be built into the blade. It provides the necessary braking force, lessens backspin, and extends the life of the blade. However, an electric braking system is more expensive and can be more difficult to retrofit onto the saw.

Skillful sawing: Even though it may seem very easy, manually cutting wood is not at all easy. It requires patience and accurate timing. As such, you need to get a decent amount of experience before you attempt to learn how to make circular saws on your own. Practice every day and assess how your accuracy and speed improve. Also, learn to sharpen your blade for every cut. It's also important to wear safety glasses and other protective equipment during manual sawing to reduce the risks of getting hurt from flying objects.

Make Cuts in All directions: You need to make cuts in all directions. Start by making cuts straight across your target line. Gradually make cuts going towards the left and right, and cut across to the right again. Straight-line saws are better than crosscut saws because they make accurate slices even without it.

Maintain a steady work piece: Your work piece should always remain perfectly still. A wobble or shift in the work piece will disturb the accuracy of your cut. If you are making a cross cut and the distance between your two saw blades is less than 0.6 mm, maintain a constant distance between the blades at all times.

Keep a blade guard in place: Your circular saw blade guard should be placed in position before starting the saw. This ensures that your saw remains sharp throughout your work. The blade guard prevents the blade from turning during your cut. Blade guards are usually available as a built-in accessory with a circular saw.

Use a table saw for general household purposes: Circular saws are primarily used for detailed woodturning or woodworking. A table saw is generally more powerful and faster than a stand-up model. For general household projects, a stand-up machine would be more appropriate. Overall, the best choice is to purchase a small-scale project and use a circular saw for most of the cuts.

Circular Saw Safety that You should Know

It is important to know the circular saw safety rules before you start using it. Beginners can safely use a circular saw to get some valuable results and safely manipulate it to reach desirable results as well. As with any power tool, though, it can sometimes be dangerous when not used correctly.

A safe way to begin using your circular saw is to stand back a distance from it. You should have a clear work area where you can see all angles of the blade and a good distance away from the blade with the workbench distance where you can keep a good distance from the blade itself. If possible, lean against a wall or block to create a safe workspace. If you are cutting something that is particularly delicate or where speed is an issue, lean to a concrete or wooden block.

Always hold the saw at a downward angle to your target. The goal is to make a clean, even cut line. If your angle is too steep or you are moving the saw too quickly for even a clean-cut line, the blade could accidentally flip over which could result in injury. Always follow the manufacturer's direction on how far your blade must move back to get to the clean angle.

If you have to stop abruptly to adjust the height of the blade, do so in a gradual and controlled manner. Make sure that there is no break in the blade depth. As you reduce the level of cut, gradually raise the blade depth until you no longer feel the need to tighten the adjusting screws. If you find yourself in this situation, lowering the saw along with the blade depth screws will help you return to a fully circular angle and complete the cut. Be sure to always look both ways before you make a complete reversal of direction.

Never rotate the blade at too high of a speed. Even with a circular saw, a sudden, violent pull or jerky action can cause the blade to reverse the direction of rotation and cut the person behind you. While the blade is rotating, the saw shoe will also be rotating and if the two do not match or are of different sizes, it is best to opt for a new blade and replace the old one.

When making adjustments to the cutting depth on a circular saw, always start at the opposite end of the table than the current position of the blade. Start by loosening the screw that holds the blade in its slot. Next, move the blade toward the open end of the slot. Keep working back and forth until the blade reaches the correct depth and is no longer binding up. If necessary, re-tighten the screw. This may take a few passes but after several tries, you should be able to get it right.

After making any adjustments to the circular saw blade, continue to use the same old blade. Do not switch blades until the hole is completely clean and any dust is completely removed. This allows the blade to catch any dust particles before they enter into the motor. Also, this prevents any potential injuries from occurring because the blades will not cut the person properly if the person is wearing a mask and mouthpiece. Remember that a poorly manufactured mask will not protect you and can even cause injury.

Circular saws can be very dangerous and cause many people to be seriously injured, even killed, when not used properly or when incorrectly used. These saws are intended for difficult jobs that require precise maneuvering around obstacles, but improper use and operation can cause serious injury. The best way to avoid having an accident is to know your saw's safety requirements and how it is used. Following the manufacturer's instructions and using your saw according to the detailed instructions provided with your equipment can save your life. Always make sure your saw is in good condition and has a warranty to cover any defects.
