There's numerous other YouTube videos describing the build process. So, no need to duplicate. However, there are a couple of improvements I've made to the design.
First, the thread-removed nipple on the end of the all-thread so the rod mates with the business-end turnbuckle body thread. This keeps the rod from moving around as one attempts to loop wire over the wing nut.
Secondly, I've welded two nuts on the "turn" end of the all-thread which acts as a nice handle and will accept a screw driver or other tightening-assist rod for torqueing.
Third, the tool end is held in-place by a locking nut allowing for easy adjustment of tool orientation and/or changing to different-use end bits.
