McDIY moving 20+foot 4x12 Header Alone, See description below.

I had to take a break from solar projects to focus on a barn that needs a lot of attention before it's too late. Here I am moving a header to make the best use of the door openings after remodel. I do almost every by myself because none of my 'people' live close enough. Also it is usually done manually with scraps and recycled materials. Although I do try to use mechanical leverage when ever possible as seen here with the ratchet straps.
First I had to support the gable end truss so I could cut away the vertical studs from the header. Then had to jack up the header and support so I could remove the studs from below. Next supported the to posts with diagonal bracing to keep it all from falling over while I moved the header. I put a couple of 1/4-20 bolts under the header to help it roll. It moved fine the first day but then I decided I wanted to move it another foot the next day. This is where I ran into the problem that kept snapping the drywall screws I used and anchor points. There was a screw that got hooked on the double top plates of the interior wall. Once I cut that off it moved pretty easily again.
I don't suggest you do anything I do in my videos. They are only for entertainment and an example of how I do things for and by myself when I don't have help or a crew. You are responsible for your own actions and safety.
