Figure 2a shows details of the inside of the
nipple side-panel of the Stewiacke Warm-Box Milk Bar. The panel is 31 7/8"
wide by 48" high. The openings for nipples are 31¼" above the
bottom of the panel. The frame consists of 2"x4" lumber on the sides
and 2"x2" lumber on the top. The side panel has three 4.5" holes
to facilitate insertion of 4-inch-PVC end caps for mounting nipples. The PVC end
caps are screwed to backing boards made of 8"x8"x¾" plywood.
Backing boards stand off from the side panel by means of ¾"x 1.5"
plywood. There is no insulation in the area of the nipples. However, there is
1.5" trufoam insulation above and below the nipple bar. The bottom of the
nipple side-panel has a 6" high piece of ¾" plywood for mounting
the electric baseboard heater.
