Oh there was no way to get a Jack to lift the old beams, at least no Jack I could have gotten would have been tall enough. From my basement floor to that joint it’s like 12-13ft.
The floor feels pretty solid now. I probably should have checked the rest of the house. We luckily have a drop ceiling in the basement
That's why you use a long 4x4 on the jack, duh. OR, you can cut the 4x4 to a length that you can wedge under the joist and jack it up as you hammer the 4x4 in a more straight angle. You really don't even need a jack.
