Ice Box "Cabinet" Install

Well, I was hoping to get further this weekend, but when the outside temperature is in the 30s, EVERYTHING must wait for epoxy cure, even when using "fast" catalyst.

So the ice box cabinet is "in", that is, "secured in place". Final permanent installation of the foam insulation will come later this week. Anyway, here is what happened...

Final foam fitment.
At this point there is 3.5 inches of foam insulation in the outer layer of the cabinet, which is an R-value of about 18.

Cabinet Base
The cabinet base sits between the bottom of the cabinet and the galley floor. It provides for a three inch kick space for all sides that face the interior.

Ice Box floor "section". Holes are ventilation. Starboard water tank underneath.
A "corner" of the floor was cut and secured to where the ice box will sit.  The base mentioned above will rest on this piece. It was cut about a quarter inch shy on the perimeter which allows the final galley floorboard to "joint in" underneath the ice box base for a nice flush secure fit. Floor boards can be removed without messing with the ice box.
Underneath the base: drain plumbing (left), lower securing bracket (right)
Plumbed underneath the ice box bottom, inside the base, is the plumbing for the ice box drain, which is 1/2 inch PVC. A fiberglass angle bracket secures the bottom of the cabinet to the 1-1/2 inch coosa board floor supports, using 5/16 bolts. Otherwise would be exposed plywood is painted (Bilgekote white) to get some sort of sealed coating on it (not for looking 'nice').
Final assembly inside the boat. Not much room to work with!
The plywood panels were lined with radiant reflective mylar in the shop (I just cut up some of those cheap emergency heat blankets). I then moved them into the boat where they were "glued and screwed" in the final assembly.
Cabinet secured in place
In addition to the angle bracket underneath, the cabinet is secured to the boat by way of five 5/16 inch bolts through the 1-1/2 inch coosa board bulkhead immediately forward of the box. The bolts are recessed in a counterbore from the forward side of the bulkhead into tee nuts previously set into the cabinet panel during construction.
