Re: Working with Lexan

We have used polycarbonate in our electronics enclosure for the last 3 years and have never had a problem with it. We used 1/4" thick for a base to hold our electronics down and 1/8" thick for doors.

To stop melting polycarbonate, slow down your hole saw.

When drilling "lightning" holes in polycarbonate use more smaller diameter holes as it will keep other robots from finding the hole and hitting your electronics.
