Pole barn question

Thanks LD1 that sounds like a fast and accurate way to set the post. So I just square up the two front post and make sure they are 24' apart. Then take two tape measures and attach one to say the left post and and one to the right post. Walk away and when you get to 30' on one and 38.5 with the diagonal one x marks the spot. Do the same for the last post. That sound right.

You got it. Except there is a difference between 38.5' and 38'5".

Same for the last post but also double check the back 24' measure as well.

Only issue is that 38'5" is an outside number. And its hard to measure to the outside point of the corner post that is already set. Its easier if someone holds the tape on the inside of that post. (or screw the tape to the inside corner through that little hole in the end of the tape.)

In this case, you would just subtract the diagonal measure of that post from your 38'5" number.

And the X that marks the spot, isnt the center of the post, rather the outside corner.

And some other things to consider, since I dont know how you are building or what future plans you have, but if you ever want walls, I assume you will nail girts to the outside of the posts. IF thats the case, you may want to make the posts 3" short of the 24x30. That way if you add walls, the actual outside of the building will be 24x30

got it and thanks for catching the measurement. Rick

I would strongly suggest that anybody wanting to use pressure treated lumber for anything above grade, especially trusses, NOT DO THIS!!!! Since the new treatment method began to treat the lumber, it is now wetter then ever before when you buy it. As it dries out, it twists more then ever bofore, and the boards actually shrink like crazy. I've seen it become over an inch shorter in less then a year. If you need 100 boards, you better buy 150 because odds are good that half of them will twist on you before you can use them. I never use 4x4's or 4x6's for anything anymore. The odds are almost 100 percent that you will not have one of them over 8 feet long that will remain straight in a years time.

I've had one 2x4x8 AC2 treated come in that weights the same as 4-5 untreated 2x4x8, it's crazy... store the lumber in the shade if you can too, if it's out in the sun, the sun side up is gonna dry super fast and you're gonna have a lot of hockey sticks.
