Hi MJ,
I'm looking at Gantenbrink's diagrams on his site, in the section 'publications'. The junction of the KC shafts is where their projections intersect below the KC. The upper points are where the projected lines intersect the casing. (Notice Gantenbrink actually uses ceilings of the passages for these projections). Similarly Cook uses the intersection of the QC shafts below the QC as a junction ; from this point to the door he makes 121 cubits for a vertical height of 77.
My understanding was that KC shaft lines intersect casing at same vertical height 154 (2 X77) above base. But now the idea is that Gantenbrinks data for casing line is wrong. What is current consensus for these intersections?
