Quoting Chuck Hards <chuck.hards@gmail.com>: Silicone adhesive comes to mind.
There are materials and techniques available now that will allow you to restrain the mirror more firmly without introducing stress.
I seem to recall mentioning primary mirror movement at the start of this thread.

As part of an ongoing project to minimize cone error in a GEM mount, for my 10" Newt I have things isolated down to mirror flop. You follow the flop rotating the scope from east to west RA and a Zhumell laser collimator. Does anyone have any recommendations on how to temporarily but safely suppress mirror flop in a 10" Orion Newt? I'm assume that the cell simply needs to be removed and the clasps holding the mirror in place tightened. On the otherhand, I understand that the free-flop movement is there to prevent stresses from building up in the mirror. - Kurt
