Thank you
I made "some" progress. This is an internal roof panel I should have explained before.

When you are working a series of outside-inside-inside-outside corners, you need to anticipate your flange movements- and in your case you will see puckers outside the steps where metal wants to gather up- and tight/tearing areas where it wants to stretch.
And that is what you got.
So, as you force the metal down into your steps, you also have to work at the 90deg angles to those steps, and it becomes a bit of a tangle until you see what is coming, and work ahead of the disasters.
So - not an easy straightforward part, but it is one that others have done, successfully, here on this forum.

Previous material was old scrap, its a thinner gauge and a softer material.
Next pictures are scrap also but of the actual material im going to use. 0.9mm. Its quite tough material but I think ideal for roof structure.

Bart, That is pretty impressive, Great Job.

Just for interest, The panel your making has a double step, where as the sample has a single, where the hinge bolts up to, Why is that and what vehicle are making those for.
Did you end up making those rear beavers for the Torana, and how well did they fit up.
Cheers

The rear panel is close to finish, I've been saying for ages but getting the number plate recess right is a challenge

That's quite a pronounced bead. Can you show how you made it. Nice stuff.

Made up the mdf guide when feeding into pullmax. I was going to mark a line to follow and free hand it but chickened out
