To turn on a 45 degree Dewalt miter saw, begin by plugging the saw in and connecting it to a power source. Ensure that the blade guard is in the full upright position for safety. Check to make sure the blade guard is properly adjusted, as an improperly adjusted guard can cause the saw to jam.
Make sure the saw is properly and securely clamped down and ready for use.
Once the saw is properly installed, locate the switch at the rear of the saw. Rotate the switch to the “On” position to get the miter saw engaged. When the switch is in the “On” position, the blade should begin to spin.
The next step is to determine which angle the blade should be set at. Increasing the blade angle will increase the miter angle. Use the angle scale to set the blade at the angle you desire, typically 45 degrees.
Once the angle is adjusted, carefully adjust the bevel and height settings.
Finally, start the saw and make the desired cut. When you are finished, make sure to turn the switch to “Off” and unplug the saw to ensure it is not accidentally turned on while not in use.
Why are my 45 degree cuts not lining up?
It could be due to a variety of factors such as the quality of the saw blade being used, miscalibration of the saw, incorrect measurement or alignment of the material being cut, or any other number of reasons.
A thorough inspection should be conducted of the saw and its components, the material being cut, and the instructions or plans being followed to try to identify the cause of the misalignment.
If the saw is found to be operating properly and is well-maintained and calibrated, it may be necessary to recheck the accuracy of the measurements of the material, making sure that all lines are square and that cuts are being made at the correct angles.
The accuracy of the cuts may also depend on the quality of the material being cut as well as the sharpness of the saw blade, so any signs of undue wear or damage should be addressed. In addition, if the material comes with any imperfections not visible to the naked eye, such as knots or other deformities, these should be taken into consideration, as they can easily cause cuts to be misaligned.
Last but not least, if the problem persists, it may be worthwhile to consult with a professional carpenter or joiner who can provide further advice and lend their expertise to the project.
How do you calculate miter angle?
To calculate the miter angle, you will need to first determine the angle of the two pieces of wood you are looking to join together. The miter angle is the angle between the two surfaces that will intersect.
To find this angle, you will need to use either a protractor or a combination square. With the protractor, you can measure the angle directly. With the combination square, you will need to measure the interior angle of both pieces of wood, then subtract one from the other to determine the required miter angle.
Once you have that, you can then use a mitre saw or hand saw to cut the angle in order to create a perfect mitre joint.
What’s the 45 degree rule?
The 45 degree rule is a way for filmmakers to position the camera in order to create a more interesting composition. It encourages filmmakers to position the camera so that two imaginary lines, drawn from two different points in the scene (such as the top right and bottom left corners of the frame) form a 45 degree angle.
This creates a more dynamic framing of the subject or objects in the scene, adding depth and drawing the eye to certain areas of the frame. Additionally, the 45 degree rule is used to draw an audience’s attention between two characters, or two different parts of the scene, to create tension and draw the eye around the frame.
The 45 degree rule is a simple but effective tool for framing shots in a more interesting and dynamic way.
How much length does a 45 degree cut add?
A 45 degree cut is used when making miter cuts, which is cutting a corner of a frame or any other structure. The exact length that a 45 degree cut adds to the length of the material depends on the size of the frame that is being mitered.
Generally, the length of the cut should equal the width of the frame. To calculate this, you would multiply the width of the frame times 1.414, which is the hypotenuse of a right triangle. For example, if the width of the frame is 8 inches, the length of the 45 degree cut would be 8 x 1.414 = 11.
312 inches.
How do you know what angle to cut?
When it comes to knowing what angle to cut, it really depends on the project and material you’re working with. Generally speaking, most cuts made using tools such as a saw or router will be 90 degrees (straight cuts), however there are a few key factors to consider to determine the best angle for the job.
The first factor to consider is the type and thickness of the material. For example, if you are working with a thicker material, you may need to adjust the angle slightly in order to create a cleaner cut.
The second factor to consider is the project, as different angles can be used to achieve different results. For example, if you are cutting angles for joinery or making intricate patterns, you may need to adjust the angle accordingly.
Ultimately, the best way to determine the best angle to cut is to consider the material and the project, and to experiment until you find the right angle for the job. Additionally, it’s always a good idea to practice on scrap material beforehand to ensure that you get the desired results.
Where is the lock on my miter saw?
The lock on your miter saw is located on the back of the saw. It is typically a small red lever that is used to release the blade so that you can move it to a different position. It is important to note, however, that you should always use the lever to lock the blade in place once you have set it to the correct position.
Locking the blade in place will ensure that it will not move out of position while you are sawing, which can result in dangerous accidents.
Does the DWS779 have a depth stop?
Yes, the DeWalt DWS779 12″ Double Bevel Sliding Compound Miter Saw does feature a depth-stop. This allows you to precisely set the length of the cut, so you can make multiple cuts of a specific length quickly and easily.
The depth-stop is adjustable, so you can change the length of the cut as needed. Additionally, the depth-stop is mounted directly on the saw so you know the cut will be precise every time. The DWS779 also includes additional features such as carbide-tipped blades for increased cutting performance and a dust collection system for a cleaner work area.
Is the DWS779 a good saw?
The DeWalt DWS779 sliding compound miter saw is overall a very good saw for a home workshop or professional shop. This saw has a 15-amp motor that gives it plenty of power to make accurate cuts. The exclusive back fence design cuts up to 2×14 dimensional lumber at 90 degrees and 2×10 at 45 degrees, so it can handle large pieces of lumber.
The cam lock miter handle with 10 positive stops allows you to quickly and accurately adjust the miter angle. The integrated XPS crosscut positioning system provides adjustment-free cut line indication for improved accuracy and visibility.
This saw also comes with a dust collector that keeps the sawdust off your workpiece and out of the air. All in all, the Dewalt DWS779 is a great saw with plenty of power and features to make even the most intricate cuts.
What is the difference between Dewalt 779 and 780?
The Dewalt 779 and 780 are both 12-inch sliding compound miter saws, but they do have differences. The 779 model is corded and runs on a powerful 15 amp motor, while the 780 is powered by a brushless motor and is thus cordless.
The 779 model is available in an extended version that includes built-in XPS LED worklight and a capacity of up to 16” in depth and 12” in height. The 780 also has an extended version that adds a blade cover, 18-inch capacity in depth, and 12-inches in height.
Additionally, the 780 model is equipped with a dual-bevel design for increased accuracy, the efficient motor delivers a longer run-time, and it has a dust collection port for efficient cleanups. Lastly, the 780 model has an adjustable pass setting on the bevel turntable and a durable aluminum base for added stability.
Does Dewalt miter saw have trenching feature?
No, the Dewalt miter saw does not have a trenching feature. Although the Dewalt miter saw is a great tool for creating angled cuts and is known for its accuracy and power, it isn’t specifically designed for trenching.
To do trenching, you’d need a dedicated trenching tool, such as a trencher. Trenchers are designed to dig trenches with a single pass, which makes them much more efficient than using a miter saw. There are different types of trenchers available, so you could choose one based on your needs.
Some of the features to consider include, engine type, power and performance, cutting depth, and other features.
