Glen Belcher from Cornerstone Tupelo in Tupelo, MS brings us this PVC pipe truss.
Glen used four 1″×8′ PVC pipes secured to 1″ PVC end caps on a wooden baseboard for the uprights. For the upper and lower supports, he used 1/2″ PVC pipe connected to 1″×1/2″ reducer fittings (8) that were cut in halves and fitted together to make 90° angles. For the cross supports, he used 1/2″ PVC attached to the uprights with pan head screws. (Note: PVC is very flexible making it hard to keep the uprights straight.)
