A circular saw is a fundamental tool in the world of wood projects. It takes special blades that are used to cut curved shapes with ease. With the following tips, you will learn how to use a circular saw effectively and safely; while keeping it well maintained so that it can serve you for many years. I have used the same tips and my saws last more than ten years!
Setting just the right depth for the blade
For a circular saw to work more efficiently and safely, you need to set the blade to a proper depth. Set the blade as shallow as possible and do not allow it to protrude too much. If you set it too shallow, it will be more dangerous since it will be too exposed when cutting. Additionally, when the blade is too deep, the saw will most likely bind and kickbacks.
Keep your blades sharp
You should not compromise your safety for anything. When you notice your saw gnawing through the board instead of smoothly going through, it is time to replace it. If also you see smoke as you work on the wood, the motor is being overworked and it is time for a new blade. Being too adamant to replace dull blades will only shorten the life of your circular saw.
Be keen about how the cut piece falls off
The easiest way to avoid binding is by allowing the cut offs to fall freely or move away. Ensure that you are supporting the board throughout when cutting to avoid splintering.
Rest the hot blades the right way
Do not rest the circular your saw blades on cement or steel surfaces. These surfaces can dull the blades due to chipping of the top grin. Instead, settle the blade on a plastic surface or on plywood.
Avoiding kick back troubles
To avoid experiencing kickback problems, avoid cutting boards that are supported on both sides. As you get closer to the end of the cutting, the board will bow down pinching the blade in the cut, causing either or both the saw and the board to kick back. This can be very disastrous not to mention the mess it makes on the board.
Know how to cut right along a straight line
This requires practice in order to do it right. Cutting along a straight line takes less effort to keep the blade on track when the blade well aligned. However, if you wander away from the line, do not insist on steering the blade back on the same line. Instead, stop the blade from spinning, withdraw the saw and start all over again.
Here is how to make rip cuts the right way
A table saw is much better for making rip cuts when compared to a circular saw. However, if you do not have a table saw, I can share a trick of making a rip cut using a circular saw. The trick is holding or securing the board in place as you make the rip cuts. Clamping is not a good way of securing the board. A better option is to use finish nails and remove them through the rear side once you are through.
Keeping the blades clean
Clean blades perform better and they do not dull quickly. Letting sap and other things accumulate on the blade will make them work inefficiently. Always remember to use brass or nylon brush to clean the blades after use.
