a)  Backward Cone assembly, shown rotated top forward.

b)  Backward Cone assembly, with the carbon fiber cones rendered as transparent to show the water channels of the cooling rings (far side).   The cone itself is stepped, unlike the forward cone, impeding the routing of the square brass tubing which runs to the cooling rings.  Also, HDI clearance for the ring 1-2 water-lines as they passe over ring 4B is extremely tight, forcing a transition from 1/8" square tubing to 3/32"X 3/16" rectangular tubing, and back again.

c)  Diagram of the Backward Cone Latch assembly, of which there are two (top and bottom).   The carbon-fiber micro-rod inserts or retracts the plunger into or out of the conical slot of the tabbed half of Ring 3B as shown.  Three registration shims control the engagement alignment.  The shaft is loaded by a jacking screw assembly at the other end, mounted on the edge of the cone, where it is accessible (views a, b).  The Cone Latch assemblies run up the middle of the water lines, straddling the edges of the Cone Halves as well as penetrating through two ridges to maintain the larger bend radius required by the micro-rod.  The micro-rod enables a non-linear push-pull latch design by virtue of its combination of flexibility with high column strength.
