This is the feeder we built in 2005 after trying many hay feeder designs. The ends have been replaced, but othewise it's still working great. The does have pushed the sides inward some so it can be snug tumbling the bales inside.

In 2012 we did some revamping; check out our new feeders on this blog. The new feeders are free standing and moveable, they have 4x4" square holed panels which means less waste.
