How to Cut a Beveled Edge Mirror

Cutting a beveled edge on a mirror requires specialized tools and techniques. Attempting this process without proper equipment and safety precautions can lead to serious injury and damage to the mirror. This guide provides a comprehensive overview of the necessary steps involved in achieving a professional-quality beveled edge.

Necessary Equipment

Before beginning, gather the following essential equipment:

Wet tile saw with a diamond blade specifically designed for glass
Safety glasses
Heavy-duty gloves
Hearing protection
Dust mask or respirator
Measuring tape
Pencil or marker designed for glass
Straight edge or ruler
Polishing compound (cerium oxide)
Polishing pads (felt or foam)
Clean, soft cloths
Water source

Safety Precautions

Safety is paramount when working with glass. Implementing these precautions is crucial:

Always wear safety glasses to protect eyes from glass shards.
Wear heavy-duty gloves to prevent cuts.
Use hearing protection as the saw can be loud.
Wear a dust mask or respirator to prevent inhalation of glass dust.
Ensure adequate ventilation in the work area.
Keep the work area clean and free of clutter.
Never force the saw; let the blade do the work.

Preparing the Mirror

Careful preparation is essential for a clean, accurate cut:

Clean the mirror thoroughly with glass cleaner to remove any dirt or debris.
Measure and mark the desired bevel width and angle on the back of the mirror using a pencil or marker designed for glass.
Use a straight edge or ruler to connect the marks and create a clear cutting line.

Setting Up the Wet Tile Saw

The wet tile saw is the primary tool for creating the bevel. Proper setup is crucial for a successful cut:

Ensure the diamond blade is sharp and specifically designed for cutting glass.
Fill the saw's reservoir with clean water to lubricate the blade and minimize dust.
Adjust the blade angle to match the desired bevel angle.
Test the saw on a scrap piece of glass to ensure it is cutting correctly.

Cutting the Bevel

Cutting the bevel requires a steady hand and consistent pressure:

Place the mirror firmly on the saw's table, aligning the marked cutting line with the blade.
Turn on the saw and allow the blade to reach full speed before starting the cut.
Push the mirror slowly and steadily through the blade, applying consistent pressure.
Avoid forcing the mirror; let the blade do the work.
Once the cut is complete, turn off the saw and allow the blade to stop spinning before removing the mirror.

Polishing the Bevel

Polishing the bevel smooths the edge and removes any sharp or rough areas:

Apply a small amount of cerium oxide polishing compound to a felt or foam polishing pad.
Rub the pad along the beveled edge in a circular motion, applying moderate pressure.
Continue polishing until the edge is smooth and free of any imperfections.
Wipe away any excess polishing compound with a clean, soft cloth.

Cleaning and Inspecting the Mirror

The final step is to clean and inspect the mirror for any defects:

Clean the mirror thoroughly with glass cleaner to remove any remaining polishing compound or debris.
Inspect the beveled edge carefully for any chips, cracks, or imperfections.
If any defects are found, repeat the polishing process or, if necessary, recut the bevel.

Troubleshooting Common Issues

Addressing potential problems helps ensure a successful outcome:

Chipped edges: Reduce cutting speed and ensure adequate water lubrication.
Uneven bevel: Ensure consistent pressure and a steady hand during cutting.
Scratched surface: Use a clean polishing pad and avoid applying excessive pressure during polishing.

Tips for Best Results

Following these tips can improve the quality of the beveled edge:

Practice on scrap pieces of mirror before attempting to cut the final piece.
Use a sharp, high-quality diamond blade specifically designed for glass.
Maintain a consistent speed and pressure throughout the cutting process.
Use ample water lubrication to minimize dust and prevent overheating.
Polish the bevel thoroughly to achieve a smooth, professional finish.

Alternative Beveling Methods

While a wet tile saw is the most common method, other techniques exist for creating beveled edges on mirrors:

Hand-held beveling tools: These tools are suitable for smaller mirrors or touch-up work.
Professional glass shops: Consider professional services for complex bevels or large mirrors.
