Minimum mirror thickness for "traditional" mirror

Hi all,
I have a 12.5" mirror that is 1.3" thick, or about 32.75mm. I was hoping to mount this in an older "tradional" mirror cell in an OTA that can be rotated any direction. Is this mirror too thin for a traditional cell (i.e., without nine point suspension and a sling)?

Thanks for the help.

Steve,

You may already know this but you can Google "mirror plop" and download a simple application that is designed to help one design mirror cells. It will give you some insight into how much your 12.5" mirror will deflect using your "traditional" mirror cell.
