A unique way to square up a foundation.

nailbender123 | Posted in Construction Techniques on September 22, 2015 09:32am

Bet you never seen this method before. I’ve used it for 35 years and it works every time.

Check out the video that explains it.         https://www.youtube.com/watch?v=B5iPfSUK1kI

I can’t get this link to highlight. Copy and paste please.

    Seems incredibly complicated.

      Yep, complicated, esp if it take 10 min to explain !

      30 seconds knowing trig and having a calculator (or even a slide rule or table of logs) and one has an accurate square anything.

        And I didn't watch all the way to the end, but it seemed to me like the scheme where you mark the middle of a string, attach its ends to the ends of one wall, then draw a line from the midpoint of the wall to the middle of the string, pulled out tight.  This line is a right angle to the wall.

        There are variations on this scheme using two tape measures.  (The old cloth ones with a loop at the end worked well for this.)  Or use a single tape, anchored at one corner, and draw an arc on the floor.  Do it again from the other corner and where the arcs cross is the centerline.

          Hello again. Im having trouble deciphering your las post.  ... "but it seemed to me like the scheme where you mark the middle of a string, attach its ends to the ends of one wall, then draw a line from the midpoint of the wall to the middle of the string, pulled out tight.  This line is a right angle to the wall." There is not a string you mark, you mark the line you have already snapped on the plate. (Are you a carpenter?) You don't draw a line you snap it. "This line is a right angle to the wall." What wall? No right angle has been created yet by the way you "explain" it.

        @junkhound

        @JunkHound. 30 seconds knowing trig and having a calculator (or even a slide rule or table of logs) and one has an accurate square anything.

         Why would I want to go to all that trouble? There is no more work than doing a 3-4-5 method. You have to snap all the lines for the plate as you do with any method which means you have to measure for dimenitions. Takes less than a minute to measure from the 2 corners to find center of the far wall and then hold the tape on the 10' mark (in this case because I used 20' as an overall measurement) and then mark 20'. Now snap the other 2 lines. Do a diagonal measurement to check for square. The only difference in the 3-4-5 method as far as time goes is the 2 measurements I take to find the center on the far wall.

         The simpler the method the easier.

      "Seems incredibly complicated." Now that's a bit of a stretch.

        Sometimes there's a tough crowd here, but they are OK.

        I don't know why sometimes newbies get hazed here.  I watched your video but it seemed complicated to me too and the truth is, I would probably shoot it with a laser.  I wasn't too interested because I most likely won't be squaring a foundation again.  Hang around, most everybody here are pretty good after they know you aren't selling anything.

          Sometimes there's a tough crowd here, but they are OK.

          Thanks Mark! I think it is because longtime framers don't want to consider that there might be a better way, or something new. 

           I'm not sure why some think it's complicated, they never explain why. Not every one has a lazer, especially a homeowner that are building it themselves. Like I explained in one of my replies, the only extra moves is measuring from 2 corners to find the center on the other wall. That matches exactly the center on the side you measured from.

           Thanks again!

    Video is what is complicated

    You must not be a framer, no framers use string lines. Framers use chalk lines to snap on the plates. If I made the video shorter, beginners woud be lost. Plus they don't know trig or have a lazer.  It is titled ...like a "pro"..

     Levels, pencils, hammers, hand saws, drill bit's, were invented long ago. Should we stop using them?

    I like this

    Thanks, your the first person i've ever met that knows this technique. After you snap your lines you just do a diagonal measurement. I've never been off more than 1/8" in hundreds of frames.
