minimal workspace for grinding lenses

What is the minimal workspace one needs to grind telescope lenses? I have
some idea of the process as a result of reading Strong's book, Procedures
of Experimental Physics, a couple of decades ago. On the other hand, someone
contemplating grinding lenses in a small apartment has to find a way to do
it with a minimum of space. It occurred to me that instead of walking around
the work, one might be able to mount it on some kind of rotating platform.
That would probably do a lot to reduce the space requirements, but I'm
not sure what kind of rotating platform would be consistent with the
requirements of telescope lens making. Does anyone know?

Apart from that, there must be a lot of other improvements that can minimize
space requirements and other requirements such as a water supply. If one
runs a hose to a bucket, maybe one doesn't have to empty the bucket too
frequently and one can then work in a garage without plumbing. Is that
the case?

If the work can be set up in a bathtub, leaving enough room to stand next
to it, one has a water supply. I don't know what kind of work platform
(including the rotating base for the work) would fit in a bathtub and remain
steady. I also don't know if one needs to cover up the work when one takes
showers or if one needs to remove it, but that seems like one possible work
site in a small apartment, and one where it is easy to clean up the mess
caused by the work, and where one can still use the work area for its
normal functions.

Ignorantly,
