Important notes for sawing acrylic sheet with a fretsaw
The saw blade will warm the acrylic as it is sawing and cause the
fretsaw blade to stick.Use a few drops of water on the blade as
you are working in order to keep it cool and running free. Ensure
that you use a medium saw blade( not too fine or coarse )
