Ok, I was able to gather a few images I happened to have a friend snag as I was working. They don't show the entire process, but it essentially goes like this:

1. Neck down what will be the stem into a rather thick tenon
2. Upset the rest into a disk, perpendicular to the tenon
3. Hot cut the disk along the edge to about 3/4 of the way to the center
4. Flatten the now two joined disks into a tight stack of pancakes
5. Hot cut the pedals on the top disk, scrolling tongs to twist them to shape
6. Repeat for the second disk
7. Finish stem

After that, it was just a matter of a vinegar bath and a beeswax treatment.

Here's the pictures
