Steps to Cutting 45 Degree Angles
Amateur carpenters sometimes shy away from circular saws because they seem difficult to control. Part of the intimidation factor is the lack of familiarity with the tool. But once you understand how a circular saw works, you’ll see that it’s actually quite easy to use. And once you get the hang of it, you can use your saw to make all sorts of different cuts, including 45 degree angles.
Here’s a step-by-step guide on how to cut 45 degree angles with a circular saw:
1.Start by making a mark on your board at the desired angle. A 45 degree angle will be half of a 90 degree angle, so you can use a protractor or a square to make your mark.
2.Next, set the depth of your blade. A good rule of thumb is to set the blade at 1/8 inch deeper than the thickness of your material. So, if you’re cutting through a 2×4, you would set the blade at 1/8 inch deep.
3.Now it’s time to make the cut. Place the board on your work surface with the mark facing up. Then, position the saw so that the blade is lined up with the mark. When you’re ready, start the saw and slowly guide it through the wood until you reach the end.
4.As you guide the saw through the wood, be sure to keep your elbow close to your side and maintain a steady grip on the handle. Also, be sure to keep an eye on both your hands and fingers — you don’t want them anywhere near the blade!
5If everything goes according to plan, you should now have a perfect 45 degree angle cut in your board. Now that wasn’t so tough, was it?
Now that you know how to cut 45 degree angles with a circular saw, you can use this knowledge to complete a variety of projects around the house. With a little practice, you’ll be able to cut through lumber like a pro in no time.
