In this blog post, we will be discussing how to cut a 45-degree angle with a table saw. The steps are relatively simple and can be completed in just a few minutes. In addition, we will also provide a few tips on how to make the process easier and more efficient. With that said, let’s get started!
Materials
Before anything, you will need to prepare your materials. To cut a 45-degree angle with a table saw, it is recommended that you use plywood or MDF boards. These are the perfect choice because they are easy to work with when cutting angles. In addition, due to their smooth surface, there won’t be any splintering and tear-out.
Step 1: Determine the angle at which you need to cut
You will need to start off with a square or rectangular piece of wood that is the same length as the angled corner you plan on cutting. If using plywood, simply mark your desired angle on the wood and use a table saw or circular saw to cut it.
Step 2: Mark the board
With your desired angle marked, place the piece of wood that is now in its right position (with the desired angle facing up) on top of your other larger piece of wood. Use your pencil to mark where you will need to saw, but leave at least 1/4 in. in the mark. This will provide space for the blade to pass through without causing any issues with your cut.
Step 3: Secure wood in place
Use a clamp or just some weights to keep both pieces of wood secured in one spot so they don’t move during sawing. You can use either screws or nails, they are not recommended because when you are cutting angles on a table saw it is possible for them to jam into the blade and cause damage. If you do choose to use nails instead of screws, make sure that the heads aren’t pointing upwards so they won’t get caught on the table saw’s blade guard assembly. Then, begin making your cuts!
Step 4: Sand the edge
After making your cut, the edges of both pieces of wood will most likely be rough or jagged. Therefore, it is important that you sand down the edges so they are smooth and even. If you used plywood, there should not be any splintering because plywood has a smooth surface. However, if you used MDF boards for this project then there might be some splintering in which case you will need to sand down the board with some fine-grit sandpaper (80-120). After that, use a piece of 220 grit sandpaper to rub over the edges one time until they are completely flush and smooth with the rest of your surface.
Step 5: Finish off
Once you’re finished sanding down the edges, it is time to finish up! Use a stain or paint to match or contrast your project’s color, and there you go! You now have a board with two 45-degree angles cut into each corner.
How to make the cut?
To make your cut, you will need to adjust the blade height on your table saw. Depending on how thick the piece of wood is that you’re cutting at this time, you should adjust it accordingly. The higher up the blade sits, then the thinner your material needs to be. The smaller the angle that you are cutting at, then there is no need for a thicker board because it will take up too much space.
But if you are planning on making large 45-degree cuts (which I don’t recommend), then use plywood or an MDF board to prevent any issues with removing enough space for your wide project boards.
Will my blade get caught?
To prevent yourself from getting injured by accident, always make sure that you have the blade guard assembly up so your hands, arms, and legs are protected from any accidents.
What is a 45-degree angle?
A 45-degree angle is an inclination of exactly 90 degrees or 1/4 of a circle. On a flat piece of material that has been cut at a 90-degree right angle (1 x 90 x 90), it takes one unit to make a perfect square and two units to create a 45-degree line from each corner to the opposite side.
What Are the Advantages Of Using A Table Saw To Cut Angles?
There are many advantages when using table saws for cutting angles versus other implements such as circular saws or routers. Some advantages include accurate cuts, strong joints, and safety.
For accurate cuts, when making angles on a table saw the wood is placed in an already secure position which makes it easier to keep your hands away from the blade. When using circular saws or routers, it is easy for users to slip up if their measurements are not precise enough. However, with table saws, the board is fixed in place so there’s no moving it around or losing accuracy with measuring. You just have to move the blade itself.
Another advantage of using table saws for angles includes strong joints. Using most other tools such as circular saws will cause thin pieces of wood to split when they are being cut at an angle because they lack stability. With table saws, however, the wood remains in its natural state and is not weakened by any split pieces.
If the angle is cut correctly then binding becomes minimal or nonexistent. Lastly, safety with table saws for angles is a huge advantage because most other tools such as circular saws and routers don’t have blade guards or control mechanisms to help protect you from injuries.
impact on the wood industry: 45-degree cuts will become more common due to the rise of craft and hobby projects. this will increase demand for table saws which require more precision than other tools.
increase in demand: course materials such as plywood and MDF boards will become cheaper but harder to find (due to increased demand) add a note about MDF meaning “medium density fiberboard”. it’s like the middle ground between “cheap wood plywood” and “real hardwood”.
What are some common mistakes people make when cutting angles?
One of the most common mistakes that people make when cutting angles is not having a proper “zero clearance insert” in their table saw. This will cause your blade to get caught on the metal framing below it if you try to cut too low. Also, the rough handling of materials and a lack of care while cutting at an angle can cause pieces to split or boards to break if they are too thin.
Tips
If using plywood for this project, we highly recommend against using screws to secure the pieces in place because when making angles on a table saw screw heads tend to come very close to hitting/jumping over the blade. Therefore, use nails instead if possible. Also make sure that if you are planning on using screws, they aren’t too long because they could get caught by the saw blades.
Please note that when making cuts on a table saw, you will most likely get some splintering at the edges of your wood. If this happens, you can use fine-grit sandpaper to smooth out the edges and prevent any possible injury that could occur from sharp or jagged pieces of wood.
Conclusion
So, there you have it, your very own guide on how to cut a 45-degree angle with a table saw. We hope that this guide was helpful and that you are now equipped to tackle this task like a pro. Remember to always use caution when working with tools and machinery.
