This is VERY interesting site: http://tinplategirl.com/ From their homepage: At Tinplate Girl, we’re putting a new spin on what you can do with it. Here you can watch videos and learn all about tinplate and how to work with it, as well as find a lot of great projects to get you started making your own tinplate work! They have a lot of nice videos showing how to work with old cans or sheet metal. They also have plans for various projects, some of which are 1:20, others 7/8 scale. Here’s a step stool in 1:20
Or how about this ore car in 7/8?
No scale specified, but it could make for a nice model…
