If more than one coil is required for each feeder line, the auger ends will have to be brazed together. Auger Brazing If the auger needs to be spliced or lengthened, locate the brazed joint closer to the power unit to minimize feed flow restriction in the line. To align the auger for brazing, lay it in angle iron and clamp securely. Rotate the auger to allow both the inside and outside edges of the augers to be brazed. Place the ends of the auger against each other. DO NOT SCREW ONE AUGER INSIDE THE OTHER- -This restricts the feed flow. Figure below and the associated chart specify how far to lap the augers. A bronze, flux-coated rod is recommended. The joint should be well filled and smooth so that it does not wear against the tube. Allow the joint to air cool. File the auger edges, as shown, to avoid damage to the auger tubes. Also, file off any brazing that extended beyond the outside radius of the auger flightings. Auger Brazing
