Make sure the surface is clean and clear of any objects that could impede your work or potentially mark or damage the sheet. Use an even and stable structure that doesn’t wobble.
Use a dry-erase marker so you can erase it after you cut the sheet.
You can also use a scoring tool to make your cuts if the blade is sharp enough to cut the plexiglass. The deeper you can make your cuts, the easier it will be to snap the board.
Be careful when you pick up the sheet so it doesn’t bend or warp before you’re ready to snap it.
Be sure the entire portion that you plan to break off is hanging over the edge of the work surface.
Be careful not to tighten the clamp so much that it puts a dent or divot in the sheet.
You can use 1 hand to brace the sheet while you push down on the sheet with the other hand. If the sheet doesn’t fully break along the line, use your utility knife to cut along the groove and break off the piece.
The fewer number of teeth on the blade will minimize the amount of dust or debris that cutting the plexiglass will produce. There are blades specially designed for cutting plexiglass that you can use as well.
Use a dry-erase marker so you can easily erase the markings if you need to make adjustments.
Make sure the sheet is secure and doesn’t shake or move.
Cutting the sheet before the saw has reached full speed could cause the teeth of the blade to snag on the sheet and create a jagged or choppy cut.
If the saw is stuttering or catching, you may be pushing the saw too fast. Stop pushing to let the blade get back up to speed and then continue to push the blade through the sheet. Make sure the 2 halves are balanced on the sawhorse so they don’t fall to the ground when you finish cutting through the sheet.
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.
Check to make sure the sheet doesn’t slide or wobble before you cut it.
A dry-erase marker makes it easier for you to erase the mark when you’re done or if you need to alter it.
Make sure the glasses fit securely on your head so they don’t fall off while you’re sawing!
If the blade of the jigsaw isn’t able to take the turns easily, it could bend the blade or break it.
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.
