Thanks Steve for posting this. As my shaping progresses, I've gathered tools and an increased ability to digest situations. These discussions help us all. While sometimes tipping or thinning aren't possible, I like knowing if and when the effort makes sense. Previously, I'd been using an edging tool, pliers and adj wrench. I especially like not having to spend time and money when what's in the drawer works!!

I know you guy like pictures. Here is a little more on the process to complete this panel. The first bend was on the orange line, then the red line. Followed by stretching in the are by the purple marks. Shrinking in the white area completes forming the arch to the panel.

The area inside the purple lines represents the general shape after the shrinking. I creased the blue line, and started tipping the lower part up. Linear stretching was required to make the new flange lay flat.

Last step was to tip the flange along the top, which is part convex and part concave. This gets a little confusing because when the flange starts to get up past about 30 degrees it is obvious that the panel will be twisted if you continue. If the bend line is a smaller radius than the edge of the flange, the edge will need to be shrunk. (Shown I red). The blue part of the flange has the edge at a smaller radius than the bend line radius, so stretching is required along the edge. Since the panel is rather small and the flange radius is also small my shrinker stretcher only worked for the first part of the flange. From that point on I used a hammer and off dolly technique to shrink and a chisel head hammer and hard steel surface to do the linear stretching.
I wish I had taken step by step pictures,but hope this helps explain the process.

Roughed out a couple more panels, cut out blanks bent in the break, stretch or shrink to match the original part. Pretty straight forward at this point. Need to be trimmed and welded to other parts later.

Tapered, twisted, radiused, time for a little planning. A few quick measurements and trace out some paper patterns to get the information needed. Since the bends are not straight I used my tipping wheel. Two of the bends are layed out on the back side, the other one on the front.

I like to work the tipping slowly (many passes) and this case I worked the pink & blue together. Tip one a few degrees then flip the panel over and tip the other one. This allows the offset and the radius to evolve without distortion. The third bend could also be tipped along with the pink bend. The flange formed by the third bend had to be shrunk to match the original part. Can't remember why I cut and welded the one area.

More later

Nice work Steve. It looks like it is taking a number of skills with a number of tools to accomplish. It is going well. Nice work!

Steve, since this is roof structure, will any of it be visible?

Kerry
Good question!
Not a lot will show, but it does in the door jamb. The one surface is exposed from the windshield back along the roof and then down the B pillar to the quarter panel.
The customer was concerned about fit of the door and drip rail. Also proper spacing from fiberglass to proper bonding.

I was concerned about those items but also strength. So I copied the factory shape the best I could.

Nice work Steve your approach to fabricating a complex piece by dividing it up into smaller segments shows a lot of planning ahead on your part. The factory most likely had problems getting it right. What method will you use to make the required welds. You must have a lot of clamps.
