ID students, take note: Eventually you may want to present a project in metal. Depending on the object you design, it may be easier to fabricate the object in wood, then paint it to look like metal. Alternatively, you could skin a wooden object in sheet metal, which raises the problem of fasteners--do you want to see exposed screw heads? You could use adhesive, but you've got to be pretty bang-on, and it might be tough to undo an error.
I'm a new fan of designer/builder Matt Jackson's YouTube channel, as he's got tons of useful fabrication tips on it. His latest is how to attach sheet metal to wood, using this interesting "reverse rivet" method:
I'm digging the look of the rivets and the simplicity of the method!
