[Spridgets] Spring washers don't work !

[Kitterer Bob]

NASA - i.e. space assets do not use "fluid" lubricants, as far as I know they do not use any lubricants but for a very different reason.  When the assets go into space (vacuum) lubricants will out gas, these vapors will re-condense on the optics.  This deteriorates / makes optical systems non-useable.  There are almost no assets that do not have some type of optical system.  So lubricants are a major no-no.
