The blog which I have made as part of my latest project is almost completed. It's up at the moment so feel free to have a look, and comments will be appreciated. The blog is a make tutorial and this one has been based on bending sheet metal. I've documented the processes which I went through so that anyone else can replicate the process when they are using sheet metal.http://www.ipd.dundee.ac.uk/users/mclark/blog/
