You can also do the same thing as Mensur said in Chimera (you have the advantage of the GUI there) using Tools->Structure Editing->Build Structure. You may also modify a fragment of your model to adapt to an alpha-helical conformation although that requires more effort. I'm not sure about the limitations of Chimera in comparison with Ribosome, I have never used the latter.
