As said on another thread, why make things harder? A 3 point cell, with the 
supports located at a radius of about 40mm will suffice. No bars needed. If 
you really want details on fabricating a 6 point cell, you can look at 
http://www.starastronomy.org/TelescopeMaking/MirrorCell/index.html for one 
example.

Clear skies.
