This thing is a 12" monster. I only have a 4' level to use as a straight

the floor.

The bed is level.

FWIW, in operation it doesn't matter *at all* if the tables are level, as long
as they're parallel to each other. If you can make one of them dead level,
though, it makes it easier to tell when they're parallel: if you can make
the other one dead level too, then they must be parallel. With a machine as
large as yours, it may well be much easier to check for level than for
parallel -- as long as your level is accurate.
