Does anyone know a good free online book on how to work with aluminium? Or a complete online course, like on YouTube. I've searched myself but I don't quite know what's worth spending time reading/watching. I'm interested in something that gives info on types of aluminium, probably even melting and moulding it, tools needed and how to work with those tools.
3D printing is still some 50 years aways from my country, and so I have to resort to different construction materials and methods for my robotics projects. I already know how to work with wooden boards (made several items of furniture in my house), but wood is not enough for a robot, not at my level of skill. I've seen some interesting robots with parts carved out of wood, but I'm no carver/skulptor, I just know how to work with boards and make them fit one another. I see aluminium is a commonly used material, and I have some toy constructor sets for kids made of aluminium, but I'd like to learn how to create parts rather than improvise from parts meant for other stuff.
