I have made a feeder out of a 55 gallon drum put it on 12ft legs all up it cost me about $150.

Also made a bump feeder out of a 35 gallon plastic barrel and have a boat winch to get it up in the air as it holds about 150lb of corn

Going to convert the 55 gallon one so I can winch it up and down getting too old to run up and down a ladder with 50lb bags of corn on my shoulder

Here is a pic of the 55 from my tree stand.
