I think internal reinforcing and design of the base to keep unsupported spans to a minimum.

Good point Dave however I have the electrical coming down from the ceiling.  I have gone to a bit of effort, not much, to get power cables out of the way in this new shop and the grinders, drill press etc are all wired from under the bench.  I have outlets for portable tools on the front of the bench which saves cables trailing over/through the work in progress on the bench.

Cnczone has an insanely long lived thread on concrete bases and concrete-epoxy.

Dick, that stuff sure would be the way to go for a really, really serious job but somehow I suspect the retirement funds might not stretch to that!   :med:

John,  

I am well intro retirement myself.

Some of these guys are looking into the damping properties of concrete/epoxy in the iron casting cavities of existing parts.  You (and I) are, I hope, beyond this obsession (Quorn anyone?).

Concrete is absolutely an option for a lathe/mill/shaper.
