What You'll Learn
Using a router or table saw
When beveling the edge of plastic with a router, safety precautions must be taken. Wear eye protection and ensure dust collection to protect your eyesight and lungs. Check your blades and ensure they are sharp to minimize vibrations and prevent cracking. Rout the ends first as end-grain has a tendency to split out.
To begin, loosen the collet or bit collar on the bottom of the router with two wrenches. Install a bevel bit with an end bearing and tighten the collet. Adjust the height of the bit so that the shoulder of the bevel sits just above the base plate, allowing for the most angled cut. Sand the edges of the plastic before routing to ensure a smooth surface for the guide bearing to ride on. Press the base of the router firmly against the plastic surface to prevent the router from tipping.
For a large bevel, a table saw set at 45 degrees can be used. However, this method can be tricky, especially for the ends. It is important to ensure that the saw blade is perfectly flat, as a warped blade can cause issues when angled. When using a table saw, it is recommended to cut shy of your line and then make mitered rips to your final measurement. This helps to prevent issues with the wood lifting or pinching.

Adjusting the blade height
When beveling plexiglass, a clear, impact-resistant acrylic plastic, it is important to adjust the blade height to ensure a precise and effective cut. Here is a step-by-step guide on how to adjust the blade height when beveling plastic edges:
- Locate the Blade Height Adjustment: On a table saw, the blade height adjustment is typically located under the table, on the side of the saw. This adjustment mechanism allows you to set the blade to the desired height relative to the thickness of the plexiglass.
- Set the Blade Height: Adjust the blade height to 1/2 inch higher than the thickness of the plexiglass you are working with. This setting ensures that the blade will cut through the entire thickness of the plexiglass, creating a clean bevel.
- Secure the Plexiglass: Clamp the plexiglass securely to your work surface. Use C-clamps to hold down a piece of hardwood with a straight edge, ensuring that the edge of the board is even with the edge of the plexiglass. Position the clamps back from the edge to provide clearance for the router base.
- Prepare the Router: Loosen the collet or bit collar on the bottom of the router using two wrenches. This will allow you to adjust the bit height and make necessary bit changes.
- Install the Bevel Bit: Turn the outside nut counterclockwise and the inside nut clockwise to loosen the collet completely. Insert a bevel bit with an end bearing into the router. Tighten the collet securely once the bevel bit is in place.
- Adjust the Bit Height: Adjust the height of the bevel bit so that the shoulder of the bevel is just above the base plate. This position ensures that you will achieve the most angled cut. Fine-tune the bit height as needed to match your desired bevel angle.
- Test the Setup: Before starting the cut, ensure that your setup is correct. Check that the plexiglass is securely clamped and that the bevel bit is installed correctly at the desired height. Make any necessary adjustments to the blade height or workpiece positioning.
- Perform the Bevel Cut: With the router turned on, slowly and carefully run the router along the edge of the plexiglass. Maintain a steady pace and ensure that the bearing runs along the middle of the hardwood edge. Repeat this process for each edge that requires beveling.
By carefully adjusting the blade height and following these steps, you can effectively bevel the edges of plastic materials, creating a precise and angled finish. Remember to always prioritize safety when working with power tools and wear appropriate personal protective equipment.

Using a buffing process
Buffing is a polishing method that can be used to finish the edges of plastic sheets. It is often used in conjunction with diamond polishing, where diamonds rotating at high speed pass over the surface of the material to create a shiny finish.
Buffing is done after the polishing process to enhance the quality of the finish. It is a low-stress method that is only used for specific specialty products. The price, material type, and intended use will determine if buffing is the best polishing technique for your project.
Buffing can be done by hand as part of a thorough hand-polishing process. This involves several steps, starting with milling the edges to remove saw cuts. The next steps are sanding through four different grits of wet-dry sandpaper, buffing with a cutting polish, and then a final buff with a fine finish.
Bevelled edges are often buffed and polished for safety, wear resistance, aesthetics, or to make mating with other parts easier. A beveled edge is created by grinding or sawing the edge at an angle other than 90 degrees. This technique is used in precision part manufacturing, metallurgy, carpentry, and automotive applications.

Adding bullnose edges
Bullnose edges are commonly added to countertops, tabletops, and cabinets. They are also used in tiling projects, such as backsplashes, shower walls, and flooring, to create a seamless and polished look.
To add bullnose edges to a plastic surface, you can use one of two methods:
- Router with a bullnose bit: This method involves using a router with a bullnose bit to cut and shape the plastic to the desired bullnose profile. It is important to use sharp blades and bits and minimize vibrations during the cutting process to prevent cracking.
- Laminating bullnose strips: This method involves laminating or gluing pre-fabricated bullnose strips to the edges of the plastic surface. This option may be more suitable for those without access to specialized equipment like a router.
When working with plastic, it is essential to consider the type of plastic and choose the appropriate tools and techniques. Some plastics, like acrylic or plexiglass, may require specific cutting and finishing methods. Additionally, safety precautions should always be followed when operating power tools.
Overall, adding bullnose edges to plastic can enhance the aesthetics and functionality of a project, providing a smooth and seamless finish.

Using a bevel bit
Beveling is a technique used to soften the edge of a material, often for safety or aesthetic reasons. When beveling plastic, it is important to use sharp blades and bits and to minimize vibrations to prevent cracking. Here is a step-by-step guide to beveling plastic edges using a bevel bit:
First, measure and mark the plastic to your desired size using a tape measure and marker. If you are working with plexiglass, which is a type of clear, impact-resistant acrylic plastic, you will need to cut through its entire thickness. Adjust the table saw fence to cut the plastic to the desired width. The table saw fence guides the plastic as it is being cut, ensuring a straight and precise cut.
Next, locate the blade height adjustment, usually found under the table on the side of the saw. Set the height to 1/2 inch higher than the thickness of the plastic. This will ensure that the blade cuts through the plastic cleanly and completely. Now, you are ready to cut your plastic to size with a square edge.
Once the plastic is cut to size, you can begin the beveling process. Clamp a piece of hardwood with a straight edge underneath the plastic, using C-clamps. This will provide a stable base for routing. Make sure to set the clamps back from the edge enough to accommodate the router base.
Now, it's time to install the bevel bit into the router. Loosen the collet, or bit collar, on the bottom of the router using two wrenches. Turn the outside nut counterclockwise and the inside nut clockwise to loosen them. Open the collet all the way and insert the bevel bit with an end bearing. Tighten the collet securely.
Adjust the height of the bevel bit so that the shoulder of the bevel is just above the base plate. This will give you the most angled cut. Start the router and slowly push the plastic through, allowing the bevel bit to cut the square edge on a bevel. Press the plastic down firmly against the table and fence to ensure a straight and accurate cut.
Finally, reset the fence as needed to cut any remaining edges that require beveling. With the right tools and techniques, beveling plastic edges using a bevel bit can be a straightforward process, resulting in a smooth and professional finish.
