For example, if you look at the joist the junction box is attached to you can see about a 4' strip I had to shim. That dip was 3/16". Put that next to other joists that might have been 3/16" high and you can see how 3/8" over 16" between joists can cause a problem.

What about "water putty" pretty cheap and looks pretty safe too, I mean if you want a lot of filler stuff.

This task looks like one that I would start, then get frustrated, put everything back and then forget about it!

Oh never mind, I see that the site says "Durhams is not made for load bearing repairs" I don't know if it counts in a compression application like you are doing.
Take a look anyway, it looks like neat stuff. I saw some at OSH, pretty cheap.

What is the finished flooring going to be? Hardwood, carpet.....?

Unless you hare coming up with large variances, such as 1/2" or greater, I think you may be overthinking this too much. If you glue your subfloor down I think you will be able to make up a lot of that. 3/16" is nothing especially if it doesn't run the full length of the joist.

To remain competitive, I also have twin 3 year old girls that could sleep through an earthquake. We just brought them home as I was putting a porch on the front of our house. To the dismay of my wife, I kept right along sawing and nailing and they never missed a wink of sleep. The hard part now is just getting them to go to sleep.

The OSB is there to accomplish what?

OSB is to stiffen up 2x8's that are spanning nearly 14'. When I started, they wobbled and deflected noticeably. And while I understand that is partly due to the removal of the subflooring, the subflooring was questionable itself and wasn't glued. Now, those joists are MUCH stiffer with the OSB. I'm also going to put in some solid 2x8 bridging at each end and down the middle. Overkill? Maybe. But if the floor moves, at least I know I did everything I could to prevent it.

Background is, I put 3/4" T&G hardwood over 14' span 2x10's with the 5/8" subfloor on my 1st floor and those joists still move. And when they move, the floors make a "cracking" sound the first couple times you walk on it. Very frustrating to look at $3500 worth of wood flooring you just installed and wonder if you could have done more/better prep.

It might be overkill, but I'm going to do everything I possibly can to make sure it's as solid as can be, as level as can be and hopefully when I am done it will be as quiet as can be.

Oh, and on the kid issue, I do continue to work after she goes down, but only if I am sanding, planing, drilling, that type of stuff. I avoid nailing or making "impact" noises or anything that will have my air compressor kicking on and off. She'll sleep through a lot, but since I'm in the room right next to her, those things will wake her up.

Have thought about it, but I'm kind of stubborn, and the wife is very understanding and doesn't give me a hard time. If I was less stubborn and had a wife nagging me I'd be doing exactly like you said. Or at least paying someone else to finish it!

When I was adding insulation to the attic, I had to work around tube and knob electrical wires. I decided that instead of burying the wires in fiberglass batts, I would cut rigid foam and put them under the wires, then cut fiberglass batts to fit around that. It took many (after hours) hours to get even a quarter of the attic done. Similar to your current project but minus the headspace and add a few dessicated rat corpses. I gave up, I just took the rest of the batts and tossed them on top of the already laid (and completely insufficient) batts that were already there. It was hot, dusty, itchy, cramped, unfulfilling work and I just said "F this!". I could have paid someone to do it, but forget it. I went from what I thought was an elegant solution to a brute force method, which works just as well, but now all my stupid tube and know wiring is hidden!

You really should have removed all the knob and tube wiring from the space.

Removing the nob and tube would have been quicker than what you went through to insulate around it.

Well the T&K removal was not a project for the time being. I was illustrating how "creative" we DIYers can be.

The T&K is fine if undisturbed (or so I hear) Any new wiring is obviously done with romex stuff. I did rewire my workshop to romex from t&k, but that's because the walls and ceiling were not finished.

I needed the photo to follow what you were trying to do. I agree with the fellows that said to sister in 2 x 8's. They are a heck of a lot stronger than OSB when flexing. Don't forget the PL Premium. Sure, select the straightest ones you can find, but I don't see why they need to be any straighter than the ones my house was built with.

Don't get me wrong, I LOVE DIY creativity. A good deal of my work has to do with correcting this creativity for the next homeowner.

Why arenít you just jacking this sagging floor up and supporting it from below?
