Cutting inside corners of quarter round can be a daunting task, but it doesn’t have to be. With the right tools and techniques, you can easily achieve a professional finish. In this article, we’ll guide you through the process of cutting an inside corner of quarter round, providing step-by-step instructions and helpful tips. Whether you’re a seasoned DIYer or a complete beginner, you’ll find the information you need to tackle this task with confidence. So, gather your tools, grab your quarter round, and let’s get started!
Before we dive into the cutting process, let’s gather the necessary tools. You’ll need a miter saw, a measuring tape, a pencil, and a protractor or miter angle finder. The miter saw is the most important tool for this job, as it allows you to make precise, angled cuts. Once you have your tools ready, you can proceed with the following steps: Measure and mark the length of the quarter round that you need to cut. Use the measuring tape to determine the distance from the inside corner to the end of the wall. Mark this measurement on the quarter round using a pencil.
Tracing the Inside Corner
Step 1: Mark the Center of the Inside Corner
Begin by identifying the inside corner where you need to cut the quarter round. Use a pencil or marking knife to lightly mark the midpoint of the corner on the wall.
Step 2: Extend the Marked Center Point
From the marked center point, extend a straight line outward on both walls that intersect the inside corner. These lines will serve as guidelines for cutting the quarter round.
Step 3: Determine the Quarter Round Overlap
Place the quarter round against the guideline on the wall and mark the point where it overlaps the adjoining wall. This mark represents the distance by which the quarter round needs to be extended on the other side of the corner.
Step 4: Transfer the Overlap Measurement
Transfer the overlap measurement to the opposite guideline on the other wall. This point will indicate the end point of the quarter round cut on that wall.
Step 5: Trace the Quarter Round Shape
Position the quarter round against the guidelines and trace its contour onto both walls, extending the markings beyond the end points. The traced lines will form the cutting guide for the inside corner.
Adjusting the Scribe Tool
Once you have your scribe tool, it’s important to adjust it to the correct width. The width of the scribe tool should be slightly wider than the thickness of the quarter round molding. To adjust the width, loosen the thumbscrew on the side of the tool and slide the two arms apart. The arms should be positioned so that the tips of the scribing needles are just touching the inside edge of the molding. Once the arms are in the correct position, tighten the thumbscrew to secure them.
Next, you need to adjust the depth of the scribing needles. The depth of the needles should be set so that they will scribe a line that is deep enough to cut through the quarter round molding, but not so deep that they will damage the wall behind the molding. To adjust the depth, simply turn the adjustment knob on the side of the tool. The knob is marked with a scale that indicates the depth of the needles.
Finally, you need to check the scribe tool to make sure that it is cutting a clean, accurate line. To do this, place the scribe tool against a piece of scrap molding and scribe a line. The line should be straight and clean, with no ragged edges. If the line is not clean, adjust the depth of the needles or the width of the arms until you get a satisfactory cut.
| Step | Action |
|---|---|
| 1 | Loosen the thumbscrew on the side of the scribe tool. |
| 2 | Slide the two arms apart until the tips of the scribing needles are just touching the inside edge of the molding. |
| 3 | Tighten the thumbscrew to secure the arms. |
| 4 | Turn the adjustment knob on the side of the tool to adjust the depth of the scribing needles. |
| 5 | Check the scribe tool by scribing a line on a piece of scrap molding. The line should be straight and clean, with no ragged edges. |
Transferring the Markings to the Quarter Round
With the measurements and angles transferred to the quarter round, it’s time to accurately mark the cut line. Here are the steps to follow:
Step 1: Align the Quarter Round with the Pencil Markings
Place the quarter round against the inside corner of the wall, ensuring that the measurements and angles you transferred earlier align perfectly. The angled edge of the quarter round should follow the angle of the wall.
Step 2: Use a Protractor or Angle Finder to Mark the Angle
If necessary, use a protractor or angle finder to double-check the angle at the inside corner. Make sure the tool is aligned correctly and mark the corresponding angle on the quarter round. This mark will indicate where to cut.
Step 3: Draw a Cut Line along the Markings
Using a sharp pencil or fine-tip marker, connect the two marks you made in steps 1 and 2. This line represents the cut line where you will need to cut the quarter round.
Step 4: Transfer the Cut Line to the Back of the Quarter Round
Flip the quarter round over and transfer the cut line to the back using a pencil or marker. This will ensure that the cut is made on the correct side of the quarter round when you are sawing.
The following table summarizes the steps for transferring the markings to the quarter round:
| Step | Action |
|---|---|
| 1 | Align quarter round with pencil markings |
| 2 | Mark angle using protractor or angle finder |
| 3 | Draw cut line connecting marks |
| 4 | Transfer cut line to back of quarter round |
Cutting the Bevel
To cut the bevel, you will need to use a miter saw with an appropriate blade for cutting wood. The specific angle of the bevel will vary depending on the thickness of the quarter round and the desired fit. A good starting point is to set the miter saw to a 45-degree angle.
Place the quarter round on the saw table and align the edge of the board with the saw blade. Ensure the board is positioned correctly so that the bevel will be cut on the inside corner of the quarter round.
Hold the quarter round securely in place and slowly lower the saw blade onto the board. Use a firm grip to prevent the board from moving or kicking back. Cut the bevel smoothly and carefully, ensuring the saw blade follows the desired angle.
After cutting the bevel, check the fit by placing the quarter round in the corner where it will be installed. If the fit is too tight, you may need to adjust the angle of the bevel slightly. If the fit is too loose, you may need to add a small shim between the quarter round and the wall or baseboard.
Repeat the process for the other inside corner of the quarter round, ensuring the bevels are cut in the correct direction. By following these steps, you can achieve a clean and professional-looking fit for your quarter round corners.
| Step | Action |
|---|---|
| 1 | Set the miter saw to a 45-degree angle. |
| 2 | Place the quarter round on the saw table and align the edge with the saw blade. |
| 3 | Hold the quarter round securely and slowly lower the saw blade onto the board. |
| 4 | Cut the bevel smoothly and carefully, ensuring the saw blade follows the desired angle. |
| 5 | Check the fit of the quarter round in the corner. |
| 6 | Adjust the angle or add shims if necessary. |
Fine-Tuning the Cut
Once you have made the initial cuts, you may need to fine-tune them slightly to get a perfect fit. Here’s how:
1. Check the fit: Place the two pieces of quarter round together in the corner. They should fit snugly without any gaps. If there is a gap, you will need to cut more off the inside piece.
2. Mark the excess: Use a pencil to mark the excess on the inside piece where it overlaps the outside piece. This will show you how much more you need to cut off.
3. Cut the excess: Carefully cut off the excess along the pencil mark. Be sure to cut straight and avoid cutting into the outside piece.
4. Sand the edges: Use sandpaper to smooth the edges of the cut. This will help to create a clean and professional-looking finish.
5. Caulk the seams: Once you are satisfied with the fit, apply a bead of caulk to the seams between the quarter round and the wall. This will help to seal any gaps and prevent moisture from getting behind the molding.
Here are some additional tips for cutting inside corners of quarter round:
• Use a sharp saw blade to get clean, precise cuts.
• Take your time and don’t rush the process.
• If you are not sure how to cut a particular angle, practice on a scrap piece of quarter round first.
• Once you have cut the pieces, dry-fit them in the corner to make sure they fit properly before you apply any adhesive.
Positioning the Quarter Round
To position the quarter round correctly, you need to:
