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!
