The area where the floor supports are located is in a crawl space with uneven ground. The joists are obviously level. I'm using doubled up 2x6 as a supporylt beam with 2 Home Depot extendable support posts. On the ground surface, I'm using, approximately 12x12, 3/4" thick steel plates as footings. Due to the uneven rock crush floor, it is basically impossible to get the steel plates level.

Can I flip the support poles upside down so that the base is on the level ceiling and the adjustable threaded ends are on the uneven steel plates on the floor?

Yes, you can flip them, but if it's stone just shuffle it around to get it close to level as possible first.

I should add, stone is under a couple of layers of plastic from the radon mitigation system. Its also quite compact and not easily manipulated.

So, can I flip, or should I try to level the steel plates? (Though I've already tried the former)
 
based on that pic...if both plates on the pole, are fixed...what good will flipping it do?

looks like there is room on the 'floor' to reposition the big steel plate...maybe a flatter area?
 
How uneven is it? Can you drill and tap the steel plate to match the bolt pattern of the base plate? Bolt the post down and then use metal shims under each corner as needed.
 
i would put some wood between the post base and the steel plate just because steel on steel can slip but it you get it perfectly level than i guess you would be fine

The upper plate toggles to accommodate uneven or unleveled surfaces. The bottom plate requires a level surface to seat properly.
 
Because I know you want one more guy to chime in.... I would flip the post - it's actually more standard practice to have the screw at the bottom and then a concrete floor is poured around it.

Once you've got weight on it there will be no slipping.

Let's get this thing going man! What's left to do before filling?
