How do you trim a sheet of Lexan plastic?

Answer 1

They say to score it with a razor and then snap it along the line but I used to make plaques out of plexi and I found that a slow speed jigsaw with a wood blade will allow you to make corners or shapes without fracturing the plastic. Just start off really slow with the blade barely moving and once the cut is started you can speed it up a bit but never full speed as the plastic will just melt.

I took two 2x4x8 and placed them on edge, spaced them 1/2" apart and used two pieces of scrap wood on the ends to keep them evenly spaced using sheet rock screws. The line on the lexan that I wanted to cut goes directly above this space between the 2x4x8. I then made my cut using a jig saw with a wood blade. As stated before make your cut slowly. Mine came out fantastic.

Answer 2

To trim a sheet of Lexan plastic, you can use a fine-tooth saw or a circular saw with a blade designed for cutting plastic. Make sure to secure the sheet firmly before cutting and wear proper safety equipment to protect yourself from debris. Cut slowly and steadily to prevent cracking or splintering of the material.
