1. A thin-walled fuser roll core assembly, comprising:
a metallic core cylinder having a wall thickness between about 0.5 millimeters and about 2.0 millimeters, an end region, and having an axial and a radial direction;
a drive gear having an internal diameter sleeve for fitting over an end of the core cylinder and a key for forcing rotation of the core cylinder;
a keyway in the end region of the core cylinder for receiving the drive gear key, said keyway having a terminus;
a means for redirecting axial oriented stress at the terminus of the keyway to a radial direction.
