to make rounded cuts in the plexiglass. A jigsaw looks a lot like a bandsaw but it’s shorter and cuts in an up-and-down motion. You can use a jigsaw to make straight cuts as well as rounded cuts so it’s a good option if you need to cut a specific shape or a circular piece out of a sheet of plexiglass.  Use an uncoated blade with fine teeth to cut plexiglass. Keep a few extra blades nearby in case you need to replace it while you’re cutting. Use a sawhorse as a work station to hold the sheet while you cut through it. Lie the sheet so it’s secure and stable on the sawhorse. Check to make sure the sheet doesn’t slide or wobble before you cut it. It’s very important to have a guide to follow when you’re using a jigsaw, especially if the shape you are cutting is round or irregular. A jigsaw allows you to create a specific shape, but you need to have a good marking to use as a guide. Use a dry-erase marker to create the outline of the shape you plan to cut. A dry-erase marker makes it easier for you to erase the mark when you’re done or if you need to alter it. Sawing a sheet of plexiglass can cause splinters and tiny particles to fly in the air. These could damage your eyes if they get in them. Before you begin sawing, put on a pair of safety glasses. Make sure the glasses fit securely on your head so they don’t fall off while you’re sawing! The jigsaw will need an opening to fit into the plexiglass sheet, so start by drilling a hole with a drill and masonry bit large enough to make a hole that the blade will fit through. If you plan to cut shape with twists and turns, drill holes through the sheet at the tightest corners of the shape. This will help the jigsaw blade turn when it gets to those turns. If the blade of the jigsaw isn’t able to take the turns easily, it could bend the blade or break it. Fit the blade of the jigsaw into the hole you made in the sheet and turn it on. A jigsaw blade moves slower than a band saw or a circular saw, so it must be brought to full speed before you start using it to cut.  If the blade isn’t at full speed when it makes contact with the plexiglass, it could catch and bend or possibly break and damage your jigsaw. It’s possible the blade could snap and injure you, so use caution. Apply steady pressure to keep the jigsaw from jumping off of the sheet. Follow your guide markings closely and slow down to take any turns. If you hear or feel the blade catching or stalling, slow down and back up to allow the blade to get back up to speed, then continue to push the saw through the plexiglass.

Summary:
Use a jigsaw Place the sheet of plexiglass flat on a sawhorse. Mark the sheet with a dry-erase marker to guide the jigsaw. Put on safety glasses to protect your eyes. Drill a hole to fit the jigsaw into the sheet. Insert the saw blade into the hole and bring the blade to full speed. Push the jigsaw slowly to cut through the sheet.
