Well I finally got around to finishing my protein feeder. Going to install at the lease this weekend bit thought I would post up some pics.
Made a pyramid to help direct the flow.
Cut the top out big enough to slide the 4" down piece into.
Here you see where I slid it down 2" to slow the flow down. Also used 3/8" rebar for a lip.
Here's a finished pic. It's sitting 40" off the ground.
