These can be a source of 8/4 or thicker Oak sometimes.... One neighbor had given me an old set of stocky bed posts that came in handy from time to time.
Here was my wife's lamp. The original weighted metal/concrete base just disintegrated, so I made a strong oak platform from a couple of bed posts:

I had some oak post-stock pieces that were laminated nicely such that they resembled quartersawn / rift-sawn grain almost all the way around. I made a couple of octagonal tool handles which were well received:

I also used some up-cycled oak to set up a nice set of custom stair steps from the garage to the kitchen. Much better than the MDF that was there when we bought the house used.
*OR* Just break down the oak, stack it, and feel secure knowing you'll use it one day
Enjoy,
Chris
