WD, I did lay out the first rib on the concrete floor , got a little brush and filled an old P nut jar with some T2 ... brushed it on each side of the puzzle’ connections , and assembled the whole thing flat on the floor , left it to dry overnight ... checked it this morning and now it feels like one solid piece

... I’ll just repeat this process till all the ribs are assembled , and in the meantime , start getting ready to slice those foam blocks ...
But as things happen ,strange things , I was talking to the roofers who were fixing the house roof (Isaac damage) and they said they have pallets of the blue foam and use a “s**tload” of that stuff all the time “ ... so a new resource , may have opened up for foam acquisition ... only thing now , is they want me to make them some portable “Deer camps ", on skids , so that they can haul to a hunting spot and leave it .... so we never know where this will lead huh ??? Funny , they asked if I wanted a whole pallet of foam ... Hmmm??? What could we do with a pallet of foam
