I'd have left them done the wrong way and said I intended it to look that way!
I've watched guys run bead rollers and they make it look like child's play.... of course I'm also certain that there's lots of ruin sheet steel that were scrapped!
It's like welding or anything else we do.... it takes doing... over and over... or you have to be willing to empty your checkbook buying more steel...
I'm just glad you did it - were willing to post it up - and not be afraid to show you're learning like all of us have done. I've got barrels of stuff I've just thrown out... valve covers I've attempted to TIG vents in that are scrap... and.. oh well you get the picture.
