[modeleng] A level lathe

I am sure we have all seen lengthy discussions on the best way to ensure 
that a lathe is level.
Why?

I dont believe that they need to be level at all.
I have a lathe that came off a Royal Navy Cruiser, and the one thing I can 
guarantee is that, at times, the sea isnt level!

The main thing is to ensure that the bed is not twisted in any way,  and the 
headstock and tailstock in line, whether or not that line is level with the 
surface of the earth or not, makes no difference.

If it did, vertical borers  etc wouldnt work. Or rather, wouldnt give 
accurate results, which they do.
The same would apply to face milling or fly cutting with a vetical mill.


Does anyone agree or disagree with me?
