Nah, it isn't going to shrink. But if fashion and too much extra cash dictate, fill it with epoxy..... :lol:

Steve,really, concrete boat,who ever heard the likes. We all know it would sink like a stone :lol: :lol:
.....OZ.

Steel is even denser, and we all know steel boats can't float! :)
(A 1" hole will make it all to too true, though, OZ!)
btw. "hydraulic" cement expands on curing. Used to fill cracks, etc. And bolting the base to a solid floor makes the fill irrelevant re. vibration. Though flilling it with anythling is a lot better than it was as a hollow casting.

This is a little smaller than a floor. :doh:
I've got cast in place steel containers for stands. They're solid.
Concrete filled steel lolly columns can be bought at local lumberyards. The cores don't fall out, even when cut. We've used sections of them for rollers for boats weighing tons. They don't even have fasteners through the sides as suggested earlier for the mill base repair. Or rebar, etc. Classic case of internet research and theorizing vs reality.
