I desire to cut a small window (camera port etc) into a larger
Lexan side window/door in my Skyranger

David,

When you are buying materials, make sure you get the right stuff. Most
aircraft glazing is acrylic and not Lexan. Even though Lexan is
superior in strength, it is not as clear, more flexible, and virtually
un-polishable. The glues etc. are different for each.
