 Cutting Plexiglass with A Jigsaw

So, you have all the tools in your hand. It’s time to learn how to cut plexiglass using a jigsaw. Follow the steps to learn more;

Step 1: Set the Plexiglass on a Stable Surface

First and foremost, choose a stable surface that supports the plexiglass while cutting. Make sure the plexiglass doesn’t fall. If you are cutting edge of plexiglass, use a workbench or table as a workstation. Or for cutting in the middle, use sawhorse as a workstation.

Then, lie your plexiglass over the workstation. Secure the plexiglass with a clamp-on guide along with the workstation. Make sure the plexiglass doesn’t slide or wobble.

Step 2: Mark the Cutting Line

Take a ruler to measure the line you are going to cut roughly. Now mark along the line with a marker. It is better to use a dry-erase marker as you can erase the line later. In case of curved shape, use a round or stencil to mark as you want.

When you mark over the plexiglass, you basically mark on a brown film paper. This paper comes with each plexiglass to protect the glass from scratching. However, make sure to draw the line accurately.

Step 3: Safety Preparation

Remember, plexiglass can easily chip when you cut. Make sure that the small pieces don’t harm you. So, wear safety glasses, masks, leather gloves, and earplugs before you start. For more safety, you can use masking tape over the cutting line.

Step 4: Start Cutting

Before you start the tool, make sure to plug the saw into an extension cord or wat outlet.

  • Cutting Straight line

At first, hold the trigger down and the guide plate against the surface of plexiglass. For cutting straight lines, start cutting slowly from the edge. After you cross the centimeters, the blade will begin to heat up.

Now you can cut more easily. Don’t start with high speed initially. It may break the plexiglass and your jigsaw, as well. When you see the blade begins to pull away from the cutting line, simply turn off the jigsaw. Start again slowly and then increase the speed.

  • Cutting Curved line

If you plan to cut shapes with twists and turns, start by drilling a hole. Use a drill bit that is compatible with the glass. For cutting the curved line, you will need a sturdier plexiglass jigsaw blade. Otherwise, the jigsaw blade cannot take the twist and turns.

After making a hole, insert the blade into the hole. You must start the jigsaw at full speed from the beginning. Elsewise, the blade may bend or damage. With the full speed in the blade, use steady pressure to cut throughout the sheet. Follow the cutting line. Make sure the jigsaw doesn’t jump off the sheet.

Step 5: Turn Off the Jigsaw and Clean Up Edges

Once you are done with cutting plexiglass with the jigsaw, turn off the machine. Remove the brown film paper and masking tape from the plexiglass. Now, if you see any rough edges, sand the edges with a fine-grit paper. Finally, your plexiglass is ready for use as you wanted.

Q: What is the easiest way of cutting plexiglass?

A: Though jigsaw works too well, it is better to cut plexiglass with hand using wheel scope. For any basic cutting shape, scoring, and then snapping is easier.
