Paper Vauban Siege elements

I am currently cutting and gluing a few sheets by Peter Dennis (Paperboys). The idea is to build all elements good to play a XVIII century Siege.

The zig-zag elements, all floor elements that require a base to stand onto, have been scaled up by 25%. The Paperboys floors are meant to be used for 40mm wide bases, mine are 50mm.

The earth ramparts are not scaled, so I will only need to cut the zig-zag a bit shorter than expected.

I have now started adding a Glacis for my Vauban fortress. Some photos below. I have tweaked some of the PaperBoys pages to make straight elements, 25cm long. I need now to design angled elements.
