Measuring tape or ruler
Accurate measurements are crucial when cutting plexiglass. Use a measuring tape or ruler to mark the cut lines on the plexiglass sheet. A metal ruler or straightedge is ideal, as it provides a stable guide for marking and can also help ensure straight cuts.
Straightedge or T-square
A straightedge or T-square is necessary for drawing straight cut lines on the plexiglass sheet. These tools help ensure that your cuts are precise and accurate, which is essential for a professional-looking finished product.
Applying masking tape along the cut lines can help reduce chipping and protect the plexiglass surface during the cutting process. The tape also makes it easier to see the cut lines, especially on clear plexiglass sheets.
Marker or grease pencil
Use a marker or grease pencil to mark the cut lines on the plexiglass. These marking tools are easily visible on the material and can be wiped off or sanded away after cutting.
