    Thank you for the video. It would be great if you did more videos showing the fabrication/construction of your weld up-buildings.

      CM pro or Construction Master Pro. You can buy the actual calculator at Home Depot or get the app and always have it on your phone.

      Do you have your columns up already? They need to be up so that you can get a measurement between them. In a perfect world, they should all be the same measurement but you need to measure between each set of columns and write that measurement on the column with your soapstone or paint pen. Once you know those measurements, you can watch the video and it will walk you thru the steps. If you’re still not sure, let me know each distance and i will figure it and let you know

    Great video- I have a question- I believe you said you measured inside your welded columns . Is there a reason you didn’t measure outside or outside ? Just trying to understand I was a little confused
    Thx in advance

      i measure inside to inside because my rafters will sit on the inside of my columns(as they should). If i was going to set my rafter on top of my columns, then I would need to measure from outside to outside of the columns. I would never actually build a barn that way but to make the rafters come out to the length that i would need them, thats the measurement i would need to start with. No matter which way you choose, remember to measure MULTIPLE times and verify your measurements before you cut your rafters.
