Professional optical workshops geared up for this size generally use polishing machines whose mirrors do not need to be manhandled on and off the machine into another stand for testing , but stay in -situ with a tilt down turntable for testing and not under threat of damage every time they are moved.
I would be a little nervous over all the maneuvering given a mirror this size will have to be tested 100's of time during polishing and figuring ... Its quite a task thats been taken on there.
