What you want to do with your Peugeot is what I'm thinking about doing with my LeTour.

Anwway, yeah, I would use the cutting disks (the larger size), then the grinding (I think silicon carbide??? of the top of my head-maybe I'm thinking about something else...) drums or the rougher grit sanding drums that you put over the rubber cylindrical thingy.

Or, hacksaw, then hand file, which is what I'd do (but then, I'm a silversmith, so I love hand tools)

Good luck!
