BigIR assembly
Below includes a few pictures of my assembly process along with some updated notes and area that are going to be stumbling blocks for anyone trying to put one together

BigIR MK III Vertical with 80 meter coil
The antenna does well on all bands including 60 meters. The SWR is low enough that I don't need to use the antenna tuner

I bought this antenna used, but in new condition, at the moment I'm using 40 radials 11 meters long
