Now I am wondering if I can cut a few of the 1x boards and do some shimming/leveling that way?

Man, life can really pile on the BS at times.

Experience is gained by solving the big problems. There are a few ways to fix it.
You won't get anything usable unless you start answering questions.
What direction do the floor joists go?
How much plywood have you installed now?
Does the floor sag or is there just a hump?

I missed your question from last night, I was a bit wound up.

The hump (curb) is the center line of the house, the floor joists run perpendicular to the hump, it's where they rest in the center of the house. This hump is only a problem (I think) where the hallway crosses over. So, there is a hallway at the top of the stairs, then you turn left, step through a 36" doorway, this is where the hump is, in that 36" doorway.

There is a slight sag to the floor but it's mostly the hump. I would say that this damn hump is about 14 to 18 inches wide and 36 inches long (again, the width of the doorway).

The plywood stops about 2 feet short of the hump. I have a piece all cut and ready to go but then I figured I should ask the question about flooring, good thing I guess.

Sorry for the rant last night, my wife is getting depressed from living in a fixer upper for the past 6 or 7 years.

Cut and remove the 1" x? floor boards over the hump.
Place a 4 ft 2x4 under the floor from side to side along side the floor joist. Glue and screw.
Add 2x4s like that on both sides of the floor joists.
Put 1" floor back down between the joist on top the 2x4s.
Cover with 1/2" plywood.

Sorry about the bite, but you can't think well, while you are frustrated.

Jaz and Samfloor: We see this from time to time in new house construction when people install engineered beams flush with the floor and hang wet floor joist off them. The floor joists shrink and we have a hump. It's usually just a matter of playing with plywood thickness over the beem. My wish is that house framers would put the beam in 1/4" low and make sure the plywood spans the beam.
