First he took a couple of those cheap metal barrels that the farm store carries and set them up outside his workshop. It was a hot day! Then he found a plastic lawn chair and set it up a safe distance away for me to watch from. (That's how I got my knee in this first picture.)
Out came the welding helmet for the next phase of welding the open ends of the barrels together, to make 2 long beds. Then he drilled some drainage holes into the bottoms.
As we were adding the hay, I scraped my arm pretty badly on the sharp edge of the cut metal. The next day DH solved the problem by re-purposing an old garden hose into an edge cover.
