How to cut rounded outside corners with a miter saw.

Want to know how to cut a quarter turn without a miter saw? If so, then you've come to the right place. Rounded corners are best cut with a miter saw. However, that doesn't mean you can't cut it if you don't have one.

In this article I will teach you how to cut a quarter turn without a miter saw. I will also teach you what tools you need to cut rounded corners. You will also learn how to do it correctly and efficiently.

So without further ado, let's waste some more time titrating and learn how to cut a quarter turn without a miter saw.

Just like other DIY projects, you need essential tools to cut round shapes. I will mention all necessary for this project. However, you must use these tools according to the method you are using to cut a quarter turn without a miter saw.

  • a tape measure
  • Winkelsucher
  • carpenter's pencil
  • A high quality speed square
  • A square box
  • Multi Angle Miter Cutter
  • A circular saw (if you don't want to use a miter box)
  • A hacksaw or handsaw (if you can't afford a power tool)
  • Clamps (to hold the part)

At what angle do I cut a quarter turn?

Your quarter round angles are based on your needs and requirements. However, most projects require 90 degree connections. For such an angle, you need to cut two pieces at 45 degrees. I already covered how to cut a 45 degree angle without a miter saw in my other article.

If you want more details, you can read my article. Anyway, back to the point, you need to make a proper 90 degree angle when combining the two pieces of wood.

Always remember that angle measurement is extremely important in woodworking. Even if your cut pieces are off by a few degrees, it will ruin your entire project. This masalah is great not only for quarter turns, but also for finishing and shaping crowns. So you have to be extremely careful when making your 45 degree cuts.

Note: In this tutorial we will try to learn how to cut a quarter turn without a hacksaw in four different ways. You can use any of the techniques mentioned to efficiently cut round or round pieces.

1. Cut round pieces with a handsaw

The first technique I'm going to teach you is using a handsaw. It's one of the easiest and most effective ways to cut trim pieces or quarter circles. If you are a total beginner, this technique will take some practice to master.

You can definitely make 45 degree angle cuts with a hacksaw with ease.

You can also use a hacksaw for better results. Quarter rounds are available in different sizes. More commonly, 8 foot and 16 foot lengths are available at most hardware stores.

I recommend finding the right length for your needs. This makes the job easier and prevents you from assembling multiple pieces that could spoil the perfection of the project.

Anyway, here's the correct way to cut a quarter turn with a handsaw.

Step 1:

Get the right size round tiles for your walls.

Step 2:

Take your tape measure and carefully measure the length of the baseboard.

Level 3:

Using your tape measure, mark a line on the amount of wood you need.

Step 4:

Use an angle finder or speed square to correctly mark the 90 degree and 45 degree angles.

Step 5:

Lay the round piece on the ground with the flat side facing down.

Step 6:

Grab your hand saw or coping saw and start cutting the wood along the line.

Be very careful when cutting and don't rush into anything. Because if you hurry, you're likely to miss the line.

As I mentioned before, even a small mistake leads to a complete disaster. Your piece will look terrible because there will be a significant gap between the two pieces.

Therefore, when cutting the pieces of wood, you need to put the saw on the pencil line and carefully cut.

3. Use a miter box to cut the round corner pieces

How to Cut Outside Corners with a Miter Saw (2)

The next method I'm going to teach you is quite interesting. You can use a simple miter box to cut the round pieces. This technique doesn't require much skill as you just need to know how to properly use a miter box.

Here is the correct way that can help you cut the quarter turn pieces with the help of a miter box. You can easily cut at a 45 degree angle with this technique. In addition to round quarters, the miter box can help you cut baseboard corners, trim, and other types of parts.

Here's the correct way to cut quarter turns with a miter box or hand miter saw.

Step 1:

Measure the piece perfectly with a tape measure and a thin pencil. Carefully draw a line on one end of the wood and move to the other side.

Step 2:

Place the workpiece in the miter box.

Level 3:

Place the saw blade/saw in the 45 degree angle slot

Step 4:

Begin cutting the wood to the exact length. Use the pencil mark line as a guide to trim the corners cleanly.

4. Use a circular saw to cut the rounded corner

The next technique that can help you cut the quarter round or baseboard piece is to use a circular saw. Now, some of you may not agree, but a circular saw can help you in many situations.

I know the quarter turns are very small and unlike the baseboard you will have a little trouble cutting with your circular saw.

However, it is still possible and I will teach you exactly how to do it without any problems. So, without further ado, let's look at how you can make quarter turn 45 degree angle cuts with a circular saw.

Step 1:

Measure the length of wood you need with a tape measure and mark the exact line on one side of the quarter turn.

Step 2:

Use a clamp to hold the frame in place, otherwise it will move and could affect accuracy.

Level 3:

Match the correct blade to your circular saw. You can use any exotic wood blade with 60 or more teeth.

Step 4:

Set the blade depth correctly. Make sure the blade is titrated more than 1/4 inch deeper than the quarter round thickness.

Step 5:

Start cutting the frame. With straight cuts there should be no complication. That's because straight cuts are extremely easy and almost anyone can easily cut a straight piece of wood.

However, if you're making slanted cuts, you can use your speed square to help your blade. As I mentioned earlier, the angle is only useful for angled cuts, and it's not required for straight cuts.
