Greenhous Build 3: Framing an End-wall for a Polycarbonate Glazed High Tunnel

This is some video of framing a portion of an endwall for a new greenhouse we're building for someone. This 1,000 square foot greenhouse will have 4-layer 8 mm polycarbonate. The framing relies on 14 gauge galvanized steel. The endwalls and purlins use 1-9/16" square tubing.
