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.
