I've published an instructable for the rest of the project here
. This is also entered into the hurricane lasers contest.
This is my first instructable, and my first contest entry, so if I've done anything wrong, I appologise.
This idea (and the asociated tool design) was part of a GCSE tech project (tip for anyone doing a resistant materials exam; making your own specialised tool gets marks!)
The rest of the project is documented in this instructable
On my project, I decided that I wanted to have a roller shutter, like on old roll-top desks. However, to manufacture a traditional roller shutter would have taken too long. Therefore, I came up with the idea of using corflute (or correx, corriboard, etc). This has other advantages too:
It is recyclable
It is relatively easily cut
It can, if wanted, be signwritten
It is availiable from old "For Sale" signs
The technique I used could also be used to produce a neat curve from corflute.
