According to the recent postings* to the list it seems that the best way to
support the
mirror for grinding , polishing and testing is to support it in its
flotation cell.
Everything else is more or less good approximation giving usually good
results but sometimes causing  unexplained ( unexpected) problems.
( The thinner the mirror the more pronounced are support problems.)


I would appreciate very much list opinion and comments  on this.
