| The filler pipe is milled from 1/8" brass rod. First, taper to scale 6" over scale 6' feet and then mill
extra scale 1' at scale 6" for pipe end. Cut off and bend pipe end into shape. The retaining ring is built by using a #43

at 8.5 feet up (both scale measurements). The control arm begins as a scale 2"x6" 9' long. Miter the arm from 5' in to
scale 3" at the edge. Cut a kerf in top of the control stand to a depth of scale 1' for the control arm. Widen this
kerf with a sharp hobby knife until the control arm fits. Then, drill a #75 pivot hole down scale 6" from top and pin
the arm to the stand with .020 brass wire. Leave the wire proud to model the NBW. |
