Can anyone in the Pretoria / Jo'burg area help me with a 30cm x 30cm piece of 1.0 to 1.5mm stainless steel sheet (or know where I can get a small piece of sheeting like that)? I want to make up an exhaust outlet deflector as the exhaust blows directly onto the pannier rack crossbar, heating things up very nicely. The galvanised steel prototype (made from a piece of guttering) has started cracking and I must make up something more permanent.
