What is a Miter Saw?A miter saw, also known as a chop saw or tenon saw, has an adjustable blade that can cut the wood at different angles. It’s used to make precise cuts for molding and joinery work.
In a miter saw, there is no sign for a 135-degree angle cut. So how do you cut it?Obviously, there is a solution. So, let’s see this.
Formula to Cut 135-Degrees on a Miter SawFor making 135 degrees angle, we need to cut a 22.5-degree angle first. For cutting an obtuse angle, we can use two different formulas. By using the obtuse angle from the formula, we can get the desired 135 degrees wood angle by making an inside cut and joining the two pieces of cutting wood. Suppose X is the desired angle (135 degrees), and Z is the angle that we will get from the below two formulas: Formula-1: 180-X = Y Z = Y/2 Let us apply Formula-1 and prove it. 180-135 = 45 and 45/2 = 22.5 which is the angle for the miter saw. Formula-2: X/2 = Y Z = 90-Y Let us apply Formula-2 and prove it. 135/2 = 67.5 90-67.5 = 22.5 which is the angle for the miter saw. So, the two examples prove both formulas work, and we can get the 22.5 degree that requires for 135 degrees angle cut. Now let us go through the detailed process for cutting 135 degrees angle.
How to Cut 135-Degrees Angle on a Miter SawThe first step in cutting your angle is setting up the tool properly. Position your miter saw so it will be exactly 22.50 degrees from one pointy edge of the board you are trying to cut (which we refer to as “the object”). You should see two points protruding out behind the back wheels of your miter saw which represent 0 degrees and 180 degrees laterally – these are called the “blade guard.” Once you have your miter saw set up, use the bevel gauge on the front of it to find a 22.50-degree angle. Place one side’s edge against this pointy edge and then draw an arc with your pencil that extends out over the blade – do not let go of either end! Now put the other side of your bevel gauge to that same peak (a different point) and see if they are at a 90-degree angle relative to each other. If so, you’ve got yourself a 22.50-degree miter saw cut in perspective for more or less any kind of project you need it for! Step by Step Guides: Follow these steps until perfecting cutting angles becomes second nature:
- Measure the angle you need using a protractor or bevel gauge
- Set up the miter saw and line it to where the cut will happen, then make sure that is set correctly
- Mark your measurement on one side of what you’re going to cut (so if doing a 22.50 degree cut like we just did, mark at even 23 inches)
- Line up with edge so it’s not longer than 45 degrees off from perpendicular – this ensures accurate cuts! This can also help prevent “kickback,” which happens when the wood moves back toward you once being hit by the blade. “Matching” angles is important because all these measurements are based around 90 degrees; for example, if someone needs another ten degrees off of a 90-degree angle, it would be from the other side so that they match up
- When you’re sure everything is lined up right and ready to go – start with your saw’s blade touching what needs to cut
- Move quickly through the wood while holding at a stable position; once done, move away as soon as possible. Let the blade stop spinning before doing anything else!
Safety PrecautionsThe most important thing about using any power tool is safety. If you can’t do something safely then DON’T DO IT AT ALL! As long as you keep these precautions in mind when operating this powerful machine then there shouldn’t be too many problems:
- Always wear protective eyewear like goggles or glasses if cutting wood, or a mask if cutting metal.
- Stand clear of the path to prevent bodily injury from flying debris.
- Never cut near power lines or any other electric cables – if you’re unsure whether it’s safe, then don’t do it.
- Place wood scrapers nearby so that all your excess material can be safely collected rather than left on the floor and potentially cause slipping hazards for co-workers or others entering the workspace.
