In the past I've seen teams such as the 488, 254, and 968 use ABS plastic as the material for their electronic boards.
In
this thread 488 describes using .25" ABS. I looked on McMaster, and the stuff isn't exactly cheap, and as always weight is at a premium.
I've never worked with ABS before, but are there any properties which make .125" ABS not viable as the backing for an electronics board, in comparison to .25" ABS? Does it bend and then crack? Or is it simply not as rigid?
In the past we've used 1/8" lexan, and filled it full of holes. But again, we're looking to go lighter. I seem to recall a post by either Cory or M. Krass or perhaps some other individual from one of the above teams detailing how ABS was the only material which was light enough and pretty enough for their liking.
Thanks!
[EDIT]
On second thought, I think this might be in the wrong place. If it is, my bad.
Also, it is darn near impossible to find out how much this stuff weighs. "ABS weight" on google does not return anything even remotely close to the weight of plastic whose full name is Acrylonitrile butadiene styrene.
The sad part: it took me several seconds to realize why I got the results I did.
