This was just an experiment to see how difficult to be to bend some mild steel flat bar gently around the wide axis.

So using a 1mm slitting disc in a 115mm Angle Grinder I made a few part cuts:


Then put one end in a vice and pulled on the other:


The MIG/MAG welded over the cuts:


Attacked it with a 40 grit flap disk:


Quick spray of primer:


and some black satin:


The actual stuff is a bit beefier (40mm x 8mm rather than the 30mm x 5mm of the demo), but given the ease of the test bend (and the fact that the bend required is very shallow (radius probably something like 4m) I think that ought to work:


Now let's try it for real!
