Re: Shielding material other than pcb
I have used inverted baking pans as chassis ( and shields),and salvaged copper window screen for shielding.
In a pinch, one can make shielding from the protectors used on screen or storm doors.
(I had to make a replacement HV cage for a TV set out of the storm door protector. Worked fine.) I have even seen a magazine article on 1/4" screen mesh being made into a chassis!
