How does it sound and feel when you walk on it? How warped was it? And was it spongy?
Yeah, I was sweating it too with no help whatsoever.
I don't know if I mentioned it before but I also used UTILITY grade 3/4" oak so EVERY piece was crap.
The shims were used to fill the transition spaces between sheets of plywood. It was a big puzzle. The deepest points were around 1" lower than the highest level. I set a long level from the plywood sheets to the high points and then filled in the space underneath with shims. Then I screwed them into the floor. I left only about 1 inch of space between each row of shims.
The subfloor was NOT spongy. It was warped but very solid. One pillar just didn't sink and the others did.
The whole reason for this is because the housing association paid TWICE to have the place jacked up to level the floor and each time did nothing. So I did it myself.
Then I just rolled blue underlayment over everything.
Then I fixed EACH piece of oak with wood glue or filler or routing out a new joint. Then I used a yellow hand floor nailer with a mallet. I used long 2 inch floor nails.
It is AWESOME though. Totally quiet. I just used a paint roller to apply a lowes finish that is supposed to mimic the look of oil.
