Got me a hot-air welder, a 4x8' sheet of 1/4" HDPE, a bunch of 3/16" x 3ft. wht. HDPE welding rods,bucked out all the pieces on my table saw and with the scraps I welded up this contraption to see if my very first corner-weld would hold water. Well, it did... for 3 days till I dumped it out, then satisfied my plastic welding apprenticeship was successful. What a pile of shit that notion turned out to be.
