plumbing wall

[dug]

So I'm out working this morning, plumbing and securing the third wall we stood up last night and discovered a problem. The first two went incredibly smooth. I made sure they were perfectly square, then tacked on a couple pieces of sheathing and stood them up. The floor is very level and they were perfectly plumb. I was confident the rest would go the same but after checking with a plumb bob this morning wall 3 was a little more than 1/8 in. out (racked) Pretty consistently throughout the 30 ft. wall. Still scratching my head because the wall was dead square, I measured at least 3 times.

My question is- can I pull it square with a cum-a-long with the 2 sheets of sheathing on (I really nailed these down, as I stated, my confidence was brimming), Or do I rip them off? My gut feeling says rip them out , but would like to hear from someone more experienced.

Anxiously awaiting answer before I destroy 2 sheets of OSB.

Thanks!

Why not give it a "little" try, as opposed to a "big" try.  Hook up that comealong and pull some; see if the rack starts coming out while at same time not starting to pop your nails.   If that works, a little more pull, another check, etc, etc.

I had a wall that because a 2x6 warped over time caused the outside to bow out over 1/2".  The wall is completely sheathed and nailed well (like yours).  A little bit at a time and it's now straight.

good luck

I would think that since the OSB is there to "lock things in place", a cum a long is going to help reduce the 1/8" distance but would not neccessarily correct the problem.

Two sheets of OSB can't set you back more than $15.....but I would also mention that 1/8" isn't all that bad either?

I guess I really didn't answer your question though?  

If you want super-precision, then I would probably rip the OSB off and fix.

Thanks for the suggestions. Since posting I did some more measuring and it's probably closer to 1/4 in. out (hard to get a good read in the wind)- too much for me to live with. You are right, 2 sheets is no big deal, I guess I'll just pull them off.

get the crowbar, wood will move alot, I was able to shift and move stuff up until my top plates were on.
