I'm thinking about using these for floor support

[Dburr1014]

Yes, I would crank them up some too. Not too much all at once, slow and steady, over a few days if you have to.

Exactly. I would remove the shims and set a 6 foot and a 4 for level on the floor. Fine the lowest corner and start there. Worst case (3) jacks will need to be adjusted. The jack catty-corner the the lowest corner will not need to be adjusted.

We raised my brother’s entire sagging house this way (built 100 years ago) from the basement and with a steel beam under the second floor. In some places, inches! The prior owner removed hip trusses to finish the attic into a 3rd floor and loaded 2nd floor non bearing walls with the roof weight. Insanity.

These posts aren't very advanced. To crank them, I'd first have to jack up the beam that they support to the new height, From there I can spin the plate on the top of the post to raise up to the new position.

I have a piece of 3/4 ply that I can cut to the stand footprint and place it under for weight distribution, but jacking up the floor is my preferred solution.

I was hoping to avoid going under that floor... again.

Although, I guess there's probably more than one way to get it done.

LOL. I was thinking something similar:

“Why is it nobody ever has time to do it right, but they always have time to do it again.”

Which is why my preferred solution is to crank the floor jack. I'm just not thrilled about having to climb back under the floor.

I did it correctly the first time. Apparently, it wasn't enough.

Far as I'm concerned, this is still the 1st time. Leveling and adjust, you're doing it right, just not done. Doesn't sound like you're being lazy either, nobody would be excited to get back down there. You're on the right track, keep it up.

No nut on the thread to just turn? The center of the thread should spin in the plate.

I wasn’t specifically referring to you. Just that the saying that was posted reminded me of a similar saying.

None of the ways you are considering are wrong. There’s more than one way to skin a cat.

But jacking up the floor is probably the best long-term solution as the floor clearly has some sag in it. Definitely sucks to crawl underneath again, but at least it looks to be operating room clean compared to some of the houses I’ve been under.

Fair enough. I guess it would be the second time if the tank was full and running.

Nope; the threaded shaft has a nut and is welded to the plate. I'll have to use a bottle jack to lift the beam that the jack supports. Then I can spin the plate up to the new height, drop the nut down to the neck of the post and release the bottle jack.

I'll try to post some pictures. Its difficult because I'm focused on the work and not stopping to use a camera.

We're cool.

 

[BeanAnimal]

Hold the threaded shaft with a pair of channel locks or pipe wrench and turn the nut with a wrench. Bottle jack will work as well if that is easier for you. Jack the beam close to the post.

UPDATE:

Here is where we are....

This is the completed work. I raised the jack posts as suggested. In doing so, the wood frame which was holding up the floor in its old position came free as it wasn't bearing any weight. So I decided to relocate it in the center between the floor posts.


This is the jack with the floor raised into position. As you can see, the floor posts have moved. This was corrected.



As you can see, the space is significantly less.


This is the bubble (left to right). Looks good!


Unfortunately, from front to back, it still looks like this (please zoom in):

So after all of this work and no shims, I'm wondering if I've really accomplished anything. I guess, if nothing else, I can sleep at night knowing that the weight is thoroughly supported.

I'll level the tank and post pictures shortly.

 

[Dom]

Darn it; I forgot the light under the floor. Guess I'm going back under one more time.

Looks like good work. Should be stable

Nice work.
The 2 Jack's farthest from the wall can come up some, equal amount.
That should fix front to back.

I would actually take your level on the floor itself and make sure it’s not your stand just to be sure.
