Hello, I asked a question on this forum a few weeks ago about how to fix a hump in the floor. A few guys here told me to remove the 1x boards in the problem area and sister 2x6's onto the existing floor joists and then continue with my 1/2 plywood subfloor. I am in the process of doing that but I have a couple of questions. First, in one of the images below I used a piece of plywood to show that even after I took the 1xs off the floor is still uneven, almost 3/8 in 2 ft. Do you think I am going to be able to use hardwood flooring? My other question is how do I transition to the 1xs in the same row? In the other picture below you can see where I cut the 1xs. This will help fix the hump in one direction, but where the plywood has to transition onto the cut 1xs there will be a pretty good hump. I had thought about using a power planer to bevel this spot. Any help would be appreciated.
