On-line resource to learn 6:8:10 Squaring (Construction)

I'm planning to build a 30x24 pole barn, and have been thinking about keep it square. I know I can measure the diagonals (opposite corners), but I've been told 6:8:10 squaring is easy & best - I'm clueless.....

Can someone tell me what that is, if it is appropriate, or if there is a website that has the info available??

TIA,

Rudy So. Indiana

Rudy, I assume your advisor is referring to the ancient discovery that a triangle with sides of 3:4:5 (which includes 6:8:10) is a right angle triangle, i.e. the corner is square.

For a barn of 30x24 you can just as easily calculate the diagonal to be 38.42 feet.

Set your building line to square with the Pythagorean formula.. in your case 30 feet square = 900 24 square = 576 the sum total is 1476 . The square root of sum is 38.418745. This is the diagonal 38 feet 5 inches.

Enjoy your work..Having two hundred foot tapes will make your layout much easier. JR

Rudy, streach a string where you want the long side to be, anchor the string at both ends. Streach another string where you want the end of the barn to be. Measure and mark the string 3 feet from where the strings cross, on the long side measure 4 feet and mark being as accurate as you can. Now measure diagonally, the 3 and 4 foot marks must be 5 foot apart, if they are not then adjust the shorter strings not crossed end until it is exactly 5 foot between the marks, this becomes a 90 degree corner. This can also be done with 6-8-10 or 12- 16-20 feet.
