Nope, just found the link yesterday.
I've tried building one using trevor marshalls plans using aluminum tape and foamcore board that I had laying around. It was failure because the foamcore was not rigid enough.
The next plan was to make my own square tubing using sheet metal and a homemade sheet metal brake using some angle iron and a hydraulic jack that I had lying around. The brake worked fine for bending small pieces, but didn't do so well with a 36" piece of sheet metal. So back to the drawing board.
I've always thought using a downspout was possible but I haven't found smooth downpipe (without the fluting) at the local hardware stores, yet.
