That's an interesting idea, I never thought of doing it like that. As to the live center, the picture I posted may not show enough to show the live center but it's there. I bought one early on as I didn't much like the idea of using a dead center.
A club member suggested I finish out the fillet by getting it close with a normal turning/facing tool, then finish the profile with a round file. I then rounded the edge of the flange by cutting a couple 45's on the edges and smoothing with a flat file.
End result seems perfectly adequate, but I do want a better way to do more. I have started making a beefier mandrel to go in a collet chuck or 3/4 jaw, maybe I'll get better results with that. I want to have this down pat before it comes time to do steam drivers. Next loco project is already in the pipe (Allen Mogul).
