cutting a fresnel
It is easy to cut acrylic fresnels with a thin abrasive cutting disc on a Dremel Mototool, or similar device. Make sure you have complete sealed eye protection: Tiny sharp acrylic particles go everywhere, and stick to your clothes and skin. It is very easy to accidently rub them into your eyes, which is very painful!

Use cutting oil or some other lightweight oil, like 3-in-1. Makes it more difficult for the saw to grab the lens and shatter it, plus it keeps the plastic swarf from flying around.
