[Al (astral highway)]

Hello, one of the chief considerations and challenges for me in the design of my project is a far lighter case and chassis than during the last trial. It was simply too heavy to be practical.

I am intrigued by the possibility of joining together Perspex pieces to make a case that could enclose a copper sheet chassis. Is Perspex/ polycarbonate tappable to take a screw or could I use self-tapping screws? Please treat me as knowing very little about the tools and terminology and tools related to assembly with screws, etc; I won’t be offended!

Ideally the structure should be capable of taking a reasonable load - perhaps 3-4 kg. I will separate the EHT power supply and encase that separately.

Thank you !
