Leveling?

[Wongster]

I've reading about having to place the lathe on a flat bench to avoid the bed twisting. My bench is definitely not very flat and I wonder if I need to improve things a little.

Currently, the lathe and its chip pan just sit on the bench. It has not been bolted down.

If it is necessary, I'm thinking of getting a piece of steel plate as base and install 4 leveling feets on the 4 corners. But... would it bow in the centre after a while? I do not have a weighing device at home. On Proxxon site, the PD400 weighs about 45kg (don't know why it feels heavier than 45kg when I try lifting it up...).

Any thoughts?
