Protein Feeder Lower Unit (w/ 5" Feed Ports)
Cut the bottom out of a 55 gallon drum. Leave a 2" flange on the barrel bottom.
Elevate the drum so that there is at least two feet under it.
Insert the funnel with the spout facing downward. Use a 2x4 (or like object) to set funnel FLUSH WITH CUT SEAM in the bottom of the drum. They are a little tight fitting by design.
Lay the drum on it's side and drill two holes from the inside out. Insert two self tapping screws from the outside inward. Spin the drum and repeat at 180 degrees. This will permanently hold the lower unit in place.
Turn the drum upside down and apply a bead of silicone calk to the seam of the drum and the lower unit. Allow to dry overnight. Install Protein Head (3 or 4 Way) to the lower unit.
Install Boss Buck Barrel Band to the drum. Make sure Barrel Band is positioned so that the three way unit will be evenly spaced between the three legs. Tighten barrel band down for rock solid positioning on your feeder drum.
Top off with the 3" Steel Boss Buck lid for optimal longevity and rust proof performance.
Add legs, round or square material is fine. Must fit over 1" tubing legs on Barrel Band. Feed height for best results is around 40".
