I Have A Pole Barn That Is 4 Inches Out Of Square I Would Like To Know How To Put My Roof Trusses On So They Will Be Square So That When The Ply Wood Goes On I Don"t Have To Block It When It Does Not Fall On 4 Foot Centers.

What's the dimensions and what way are the the trusses running and did you check the diagonals to see that it's 4" out of square?

Are the trusses 16" centers or 24" centers?

I would say just start from the center, - - make sure it's perpendicular to one wall, - - then just work from that truss out, in both directions, - - the only ones that will be off are the ends.

Tony.

I assume the trusses are running the 32' way. So mark your first and second 24" truss layout and then pull your tape at a diagonal to the other side until you you hit 32' 3/4" and that will be your mark that sets the trusse square from one end to the other.

This is a funny post - like Tom said, you can't. You have to set the trusses square in order for them not to be out of square and avoid sistering for nailing the roof deck. The only thing to do is pick where you want to have the out of square trusses once you get to the end of the roof. You could start on one end and set them all square all the way to the other end and then deal with the two end trusses being out of square, or as Tom said, start in the middle and deal with them on both ends. Tom's way splits the out of 'squareness' in half. For example if the framing is out of square by 4 inches, starting in the middle means your last trusses on each side will be 2 inches out of square.

HOW WOULD I IF THE 6BY6 POLES ARE ALREADY SET?
As others have posted - the roof can be put in square but somewhere the 4" have to be accounted for.. like Tom and Mike have said - 2" on each end is most probable. I guess hindsight is 20/20 and it should've been put in square to begin with :)

How about padding the 2 oposing corners 2" each and make it square
If it is a poll barn pad the corners and then run your 2 x 4's and install siding.

Man, if you haven't started it's simple, we work on block worse than this everyday.
Set your birds mouth to the straightest side.
Lay out from both ends and leave your 4 inches in the middle. Am I really supposed to be telling these tricks???
Dont pad out anything. Just run it; your probaily not running soffit right?
Also, trim all your tails pulling off the birds mouth regaurd less of overhang.
The rope and come along are a good idea too.

Even if you are running soffit it wont matter. It'll look good.

Or, find out where your out(out of square), stiff leg your beam, pull the nails out of the beam and slip your gas powered trim saw behind it and cut a notch in the post. Get'er done!
