Figure 8 shows details for preparing a 200-litre
plastic barrel for the Stewiacke Warm-Box Milk Bar. A portion of the top is cut
away with a jig saw. A 1¼" hole is drilled near one edge of the retained
top to insert a plastic PVC pipe for the feeding tubes. A plastic bearing block
for the mixer shaft is attached to the inside and centre of the bottom of the
barrel with stainless steel screws.
