Replace the 24-tooth blade that came with the saw with a 50- to 60-tooth blade for cleaner crosscuts in solid wood, veneered plywood, and other sheet goods. Because a circular-saw blade cuts on an upward rotation, the bottom face, in which the teeth enter the cut, will almost always have a clean, tear-out-free surface. “A custom edge guide for your saw not only beats tear-out, but also makes it easy to align cuts. Start by building a jig based on the drawing below; adjust the width as needed for your saw. We made ours long enough for crosscuts in 4′-wide sheet goods. Make the base’s cutting side about 1⁄2” wider than the distance between your saw’s blade and the footplate edge below the motor.
Find the Proper Saw PositionThere’s no hard-and-fast rule regarding which direction to make the cut, but whenever possible position the saw with its motor facing toward the larger section of board that isn’t falling away when cut. Make Easy, Accurate CrosscutsMaking perfectly square crosscuts with a circular saw is easy, if you guide the saw with a layout square. Clamp the pieces, then adjust the saw blade to its maximum depth of cut, and saw through all the sheets at the same time.9.
If you’re not an experienced user, your best bet to make straight cuts every time is to use a circular saw guide like the Kreg rip-cut guide. It’s great for making straight rip cuts, repeat cuts, and most important of all, you get to make straight cuts every time as you push the circular saw along the slide. Follow the above steps, and you’ll make straight cuts with your circular saw every time.
circular saw cutting tips Related Question:
Which side do you cut with a circular saw?
When appearance matters, make cuts with the good side facing down, as circular saws can splinter the wood on the top side. Making your cut line on masking tape can reduce splintering. Start over if you see that you’ve veered off from the cut line instead of trying to curve your way back on track.
Why are my circular saw cuts curves?
A faulty circular saw is likely to have issues such as an unstable blade or a warped blade edge. The problem could also be the way you operate the saw. If you do not operate the circular saw properly, it will not cut straight. Let’s discuss several causes why your circular saw might not cut straight.
Why do circular saws cut upwards?
The saw’s motor runs the blade rotation in a way that the circular saw teeth direction points up as it enters the wood you’re cutting. It’s intentional to create the most stable, accurate, and safe cutting. As the blade teeth hit the material, they rip from the bottom through the top.
Why does my circular saw kickback at the end of a cut?
Overheating a saw blade can cause it to warp and result in a kickback. Buildup of sap on the blades, insufficient set, dullness and unguided cuts, can all cause an overheated blade and kickback. Never set a blade deeper than is required to cut the work piece 1/8 in. to 1/4 in.
Why wont my circular saw cut all the way through?
Here are some reasons your circular saw keeps stopping: Make sure your work piece is properly supported so it doesn’t pinch the blade which could also cause kickback in addition to stopping. Damaged, warped, loose or dull blade. Motor malfunctioning or overheating. Cable problems like frayed cord or weak connection.
Can a circular saw cut curves?
Circular saw technique The first tool that comes to mind for cutting curves is a jigsaw, but if the curve is gradual, try a circular saw instead. It’s surprisingly quick and easy to cut a smooth curve with a circular saw. This method is for cutting rough curves. Don’t try to make furniture with this technique.
Why is my circular saw stopping mid cut?
The circular saw stops in the middle of work when the blades of the saw are dull or damaged and are not functioning correctly. Moreover, it can also stop working when the motor of saw is not working properly. However, there could be some other reasons like cable issues, voltage issues etc.
What is the space between two protruding teeth on a saw blade called?
Gullet (handsaw) The space between a saw’s teeth, where the saw dust is carried out. It is an equilateral triangle, just like the file that shapes the teeth.
Which way should the teeth face on a circular saw?
The teeth should be cutting UPWARDS, in a clock-wise direction. You’ll also notice that when your blade is installed correctly, the teeth will be pointing upward. Remember: circular saws (as most saws) cut on the upward stroke.
Which side of the line should you always make cuts on?
Always cut to the outside of your mark line because you will have to round off your edges regardless. For thinner wood, a jigsaw can provide better results.
What saw blade makes the smoothest cut?
With fewer spaces between the teeth, crosscut blades remove less material, resulting in a smoother cut. It also means it takes these blades longer to move through wood. Crosscut blades are the go-to choice for finish carpentry and other applications that require precision and a smooth finish.
What happens if you put a circular saw blade on backwards?
You can run a saw blade backwards and it cuts pretty well. However it is not at all a good idea. The two big reasons not to do this is that saw tips are much more likely to come off if the saw blade is run backwards and that the whole saw blade is much more likely to come apart if it is run backwards.
Which way should saw blade face?
When installing a new blade, make sure the teeth are pointing downward to enable a clean cut through the workpiece. Upward-facing teeth can cause a severe injury to the operator.
How do you hammer a circular saw blade?
Place the blade on the anvil. Hammer down all ridges or lumps while using as few blows as possible to avoid expanding the metal too severely. If there’s a loose area, mark it and hammer between the mark and the blade’s rim to stretch out unnecessary tension.
How can you tell if circular saw kickback might happen?
Kickback happens when the saw blade binds or stalls suddenly in the wood and the saw gets driven back toward you. So the key to preventing this is to make sure your blade doesn’t bind in the wood.
