Figure 13 shows details for a 1¼" PVC pipe to hold the feeding tubes inside the barrel for the Stewiacke Warm-Box Milk Bar. This pipe provides a safe place to insert the feeding tubes so they do not get tangled with the mixing shaft. The PVC pipe is about 36" long. It has a notch cut at one end to form a leg of about 1¼" in length. The notch exposes the one-way valves on the milk lines to milk at the bottom of the barrel. The pipe attaches to the side of the barrel with a plastic clamp and stainless steel hardware.
