I think you're doing fine. Nothing will support the floor like a wall. I have seen often, that a main girder will run down a hallway under one wall, and the wall on the other side will still have enough load to cause the joists to sag 3' from the main girder. Support issues will drive you nuts. Most building inspectors and firefighters hate those basement jacks. Be careful using them. When you raise that big jack in the center, the two basement jacks could fall on you.

Be extremely careful, this is the kind of work that can get you seriously hurt.

Oh! welcome to the forum Nathan.

Default Looks good

When you look at where the beam is compared to where the load bearing wall is you should be no more than a 45 degree angle.

That is rule of thumb anyway, like the cone of compression in soil.

Just make sure those hangers you are putting in have the correct fasteners, no screws.

Good luck on your project,

Well, $300 later and about 9 hrs by myself and jacking has comenced....

I'll post the results on Monday, pics included....

Looks like my 3 setups are getting all joist except the one under one wall, so one more 20 ton'er on the end of one 4x6 beam and that should do it.

Metal post just hanging there by two nails. So I secured the joists under the kitchen wall and let everything back down onto the metal post, allbeit everything (floor joists) are still .5 inch higher than the were before I started...as evident in this pic of the previous DIY'er wall header staying attached to the jacked joists.

The house may have been built a little off. Raising the floor to level when the house was built with a sag in the floor will bring this kind of thing up.

OR

Has there been a repair done in that area previously? If so, they may have masked the problem and now that you are fixing the problem correctly, the previous repair has become another problem for the list!

Dominos. Fix one thing and that breaks another.

Doing it right, like you have been doing, will eventually make all of it right.

Press on.
