Wood table ideas

[BK911]

Hey guys, bought a couple of wood chunks to make a pair of tables for the cabin.
Not sure exactly how to make the base.
Saw where some have used black iron pipe, and some have used rough cut ~4" logs at each "corner".
Also saw where somebody used a ~12" stump in the middle.
These things are HEAVY, so want something sturdy.
Any recommendations?

I like the stump in the middle idea.
