Angles on a table saw can be determined by using a protractor. Also, trigonometry can also calculate the angle based on the radius obtained from a protractor reading. Other methods include: moving the saw to multiple locations and taking measurements while changing the blades or using a ruler and protractor.
– A measuring scale, i.e., centimeter or inches tape
– A high-quality framing square
– A drafting triangle
– A sharp pencil
– A magnifying glass is also recommended if your eyesight is weak or if you are looking for the best possible precision.
How to Determine Angles on a Table Saw?
1. Calculation of the table saw blade angle by using a protractor
The first technique for you to learn is calculating the table saw blade angle by using a protractor. To do this, you will need to make two calculations, one on each side of the blade. Then, move along the blade using either 2cm or 1 inch at a time until you have taken 14 measurements, depending on how accurate you want to be. You will then need to subtract the two sides together to get the angle of the blade.
2. Calculation of the table saw blade angle by using a framing square
To do this, you will need to measure two points on either side of the blade. Next, you will have to find out how far apart they are. To do this, you can use your measuring stick or try asking someone else how many centimetres. it is between these points. Next, you will need to take the square and put the edge across these two points. Then, unroll it to the edge of the blade and mark where it hits. Now, measure how far it went and multiply that by itself and you should get a result close to 90 or 180 degrees. This is what you will use for your angle reading.
3. Calculation of the table saw blade angle using a drafting triangle
This technique involves using a drafting triangle to get your angle calculated from both sides of the blade at once. To do this, you will first need to measure for half the width of the blade. Set your measuring accessory and stick it down on one edge. Then, take a pencil and mark where it hits the scale on the other side. Using the same method as before, you will need to find out how far away from your first mark. Set your triangle on this distance and use a sharp pencil to put an X on both sides of the blade. You will need to find the angle by sighting at the dot on your pencil and then reading down the other side. For accuracy, you will need to do this three times to make sure it is close enough.
Common Saw Angles
Here is a list of the common table saw blade angles:
0°: A 0° angle (flat) means that the blade is not tilted at all, or put another way, it is parallel to the ground. This is usually only a practical setting for ripping thin stock such as plywood. Commonly used with a rip fence.
15°: The most commonly used angle for crosscut work and general use. Requires a miter fence to be used correctly.
25°: A commonly used angle for cutting longer boards.
38°: A commonly used angle for cutting the end of longboards and ripping to longboards.
60°: Used to cut the middle of shortboards. If you want to cut the ends, then rip them instead.
80°: Not often used because it is a little extreme for most use cases. Used for cutting the ends of boards. It may require the use of a push stick for best results.
90°: The most commonly used angle for cutting shortboards into two pieces. Make sure to place a miter fence on top of your workpiece, or it will splinter easily. Requires a miter fence to be used correctly.
35° and 45°: These angles are rarely used because their use cases overlap with so many other angles. They are usually unnecessary.
Tips for Measuring Angles for a Table Saw
1. Make sure to use a large and magnifying tool to get the most accurate reading.
2. Buy a framing square that gives you much more accurate calculations than a standard scale.
3. If you are looking for the best possible precision, then keep winding your protractor or drafting pen until you get your tenths of a degree (0.1) reading.
4. You can use a table saw to cut to shorter lengths by using an exact length every time.
5. If you want to make sure that you are cutting at a precise angle, you will need to use a protractor. Ensure that the paper on which the protractor is printed cannot be seen through.
6. Make sure that your workpiece does not have any bowing because it could throw off your measurements, and it may even damage your table saw if it is warped enough.
These are the methods to determine the angle of a table saw blade, which is an essential skill for woodworkers. The best way to avoid mistakes in your woodwork is to make them on purpose. With these techniques, you can experiment and find out which one fits you best. Good luck!
Frequently Asked Questions
Q. How do you find the correct angle for rip cuts versus crosscuts?
A. It is important to note that the correct angle for an individual application will vary. However, in general, crosscuts are usually at a steeper angle than rip cuts.
Q. How do you make angled cuts on a table saw?
A. To make angled cuts on a table saw, you will need to use some guide. The miter gauge and miter fence are most common, which can be adjusted or locked into place for accurate cutting. You can also use a push stick, but it requires more attention to ensure that you are using it properly.
Q. What are the different types of saws?
A. Different types of saws include:
1. Miter Saw
2. Compound Miter Saw
3. Portable Table Saw
4. Jobsite Table Saw
Q. Name some top brands for table saws?
A. Some top brands include DeWalt, Bosch, Porter-Cable, Ryobi and others.
