Default Radiator Shroud

I am new to metal shaping but looking to learn, just hope an old dog can learn new tricks.

A radiator shroud is my project. The shroud will have on 90-degree bend on the top and bottom and the sides will have a double 90 to create a mounting flange. Guessing the 90 bends would be made last. In the center is 15-inch circular hole for the fan blades. Around the 15-inch hole I need a 2-inch wide flange at 90 degrees.

Started with a smaller sample but after receiving my shrinker/stretcher my sample was to small to use the s/s so I cut in two so I could practice. Started rolling and stretching. At about 75 degrees the flange that I was stretching started cracking. Not sure if my technique and or material are wrong. Have been reading about material for drawing on this site. The sheet I a have is cold roll.

This could be made in aluminum or steel, am leaning towards steel.

My only knowledge of metal shaping has come from watching videos online. David G’s video has been mentioned many times on this site so I have ordered his video.

To sum things up I need an intervention by those in the know.

Thanks Kevin
