Lid/Baseplate materials

[Flag Captured]

I used 5mm 6082 alu (from Aluminium Warehouse) in Overdrive/Banana Overdrive and that's not even slightly budged. It's nice but thick, and a lid wouldn't be nice from it. if you can get 5mm ti in, I doubt anything will crack that - even 3mm won't, but Nipper is scary and I'm told it's gone through 3mm ti so... yeah.

My best advice would be something like that with a HDPE over-layer, doesn't have to be thick but does provide a bit more protection than just a sheet of something on its own but it's totally dependant on your design. Also +1 to what Nick says, Shard turned HW2's top plate into a banana (2.5mm stainless) just because it wasn't recessed behind the back panel...

The key thing I'd say is you want enough flex to absorb the impact, but enough strength to not be damaged by it if that makes any sense whatsoever
