I'm working on the roof skin I posted about and doing it in sections as Peter suggested. What I'm finding is that I'm having difficulty turning the edge of the fairly low crown panels without everything going to hell. Rear roof section requires that I turn down 90 then turn back up 90.
Lack of tooling is one problem. I've got a proper anvill ordered from Hoosier to help with turning the panels on the wheel. My cheapo bead roller with a tipping roll stretches it to much (maybe can be cured with better setup IDK) so I've been blocking in the first line and turning it down that way. I should add that I get the shape of the roof skin right first before I do this. That has been surprisingly easy it's the turning and dealing with the damage that has been hard.
So after blocking it in and creating the line, and correcting/planishing everything (takes a long time) the piece needs more shape. I know that is from stretching from blocking the line and turning it with the sheet metal pliers. I have yet to be able to turn the line shrink where needed and be good. By the time I correct the shape, block in and planish/finish the line I have a large amount of time in a seemingly simple piece. But I have been able to get it all in control and back in shape.
Then I attempt to turn the edge 90 degrees up again, this is where I lose control of it. I have been doing it as Peter did the door shut in Vid #8. I can turn it and create the line, but I lose control of the edge and not able to keep it uniform as I do this. When I do get it turned over I can get the lines correct and planished, and keep the correct profile on the bends but the top (actual roof part) goes to hell and usually shows way too loose. As does the top edge profile. I can correct it some by shrinking/stretching the upturned edge but can't get it back to the proper profile. I can get the edge of the top profile back in shape but as I go deeper into the panel is where it goes to hell. I'm about ready to trash my third piece (Lord knows how many hours in those) as it is way too loose (stretched). I have tried to correct it on the wheel but can't get back to where I was originally. Once it has those two turns in it the only way I can get any shape in or out is by stretching/shrinking the upturned edge. Wheeling doesn't seem to do much until the entire panel seems to be stretched to much. It's very frustrating, and I know there has to be a better, much faster way.
So any advice would be appreciated. Specifically on turning the edges without doing so much damage.

rails. When you turn the flange back up 90 degrees (approximately) after first turning it down 90 degrees(approximately). I made multiple mistakes while trying to do that the first few times which lead to me posting this. I am making progress as I am understanding the mistakes I made (not bending it exactly at the radius, trying to correct that afterwards, allowing the angle between the top of the roof and the first bend to change, lots of mistakes.) I'm not good at describing this stuff exactly but maybe you can understand. I've gotten both of those pieces done and looking satisfactory. Working on the sides now. Thank you for all the help and advice. I'll take some pictures and upload them to show some of this. Right now though I'm making progress and feeling better about it. I'm just extremely slow, which is frustrating as well but I know you gotta crawl before you can walk.
