Another reason this armour is used is that it is much lighter than tranditional spaced armour, so you can use it on fast reconnaissance vehicles and vehicles which are to be airdropped. Back on topic...
As for how to replicate it, can I suggest taking a paperclip and doing the following:
-The paperclip consists of 3 "U" shaped bends of wire. Cut it up so that you get 2 "U"s with even length ends- one larger than the other.
-Collect a number of the large ones and interleave them with the curved part facing opposite direction. This will give you a range of parallel metal bars with curved edges at the edge of the armour.
-Make verticals with thin strips of plasticard at either end of the plate.
-Use the smaller "U"s for smaller plates.
The nice thing about this is that it does not involve bending the wire. I will try and do a sketch to show you what I mean.
EDIT: grrr this does not work due to the black background, but if you click on this it will take you to the picture that does work. Can a mod fix this?
EDIT2: saving to BMP then resaving to JPEG fixed it, although I am not sure that that should be needed.
