Great to see chips Steve.
The method you used to mount the mandrel, using the collet itself should work but for some reason doesn't. I did the same thing resurfacing the mount for a collet chuck. I turned a heavy piece down to give a 1 inch spigot, then grabbed that with the collet chuck. You would think this should remove all runout, but when I ground the taper for the lathe spindle mount I still had 1 thou runout. No idea where it crept in.

Free advice is worth exactly what you payed for it.
