David, I assume you mean 1/4 galvanized pipe, not 1/4 gallon pipe. Before I changed to dual lance, I did make my own lances and covered them w/heater hose for insulation. I prefer the dual lance. I also have straight nozzles, 45 degree nozzles, & kick-back nozzles ( used for the vertical part of the plenum you cannot see). You an make the different angles you want w/45 and 90 degree fittings from the parts house.
