I have never thought of using a form tool for repetitive shapes. My question is though, in the picture it looks like the form shape is larger than half and "passes" the centre point and would be kinda rubbing as the work rotated "up" not cutting as it were on the "down" side? Or is that just perspective?

Phillip,

The tool does indeed extend past center. I do it that way because it's easier to grind and set up the tool. To keep it from rubbing on the backside, I just cheat it off center a couple of thousandths. Doing it this way leaves a nice, clean radius without the tit at the center you would get with the tool on dead center.
