to make it smooth for floor covering. Can I use 4X8-7/16 OSB what they call wafer board. The carpenter used this same stuff but 3/4" to replace some of the rotten 1X4’s I am just trying to save money this house has cost me way to much already and I am running out of money fast. So if anyone has a idea of what I can use over this sub flooring that would be cheap please let me know. One carpenter suggested 4X8-1/2 CDX plywood and then rent a floor sander to smooth the ruff spots. I don’t know so if you have any good ideas please let me know and let me know about using the 7/16" OSB.
Also before I put down over-lay would it be wish to put down 15# felt between sub floor and over-lay ? There are a few spot in the 1X4’s with gaps no more than 1/8" I was thinking of this to block any air, etc., etc.,
I d determine what will be your final floor covering before I decide . You might be able to go as thin as 3/8 ply. But your final flooring may decide. Raising the flooring to much you may have troubles for clearances,such as entry doors ,dishwashers, refrigerator etc GL

Although OSB will work, your better choice is plywood
