yeah- whatever is needed- in the pic you can see the end is a tighter scroll/bend so I used a jig like yours- 'ceptin I welded 2 small pieces of Pipe on to a piece of angle and worked the scroll shape in it.

Needed a gradual bend so I experimented with the 4" Pipe.

The Mrs. made this little Firepit and the scrolled feet were bent this way.
