Time to go Stage II!

Used a router to round some of the edges. The end piece of the plenum will be welded to the main body with a cleaner butt weld, leaving a nice rounded edge along the rear corners.

With the plenum end piece hammer formed and some priliminary finishing done, I clamped the piece to the buck to perform some stress relieving to take the spring out of it.
Before the stress relieving, when I would remove the piece from the buck, it would try to spring back to it's original form of a flat sheet. After the stress relieving process, the piece more closely conforms to the shape of the buck when it's removed.
The stress relieving involved heating the piece with a torch to around 180-200 degrees F.

The buck got a little toasted, but it has served it's purpose very well.
Now to fit the end piece to the main body.

Donny when are we going to see this Bad Boy at the track?
I'm not making any predictions. This sort of fab stuff is something that comes very slowly for me. I don't want to make any quick, wrong steps. It would be disastrous if I had to scrap a piece at this point.
