The Nielsen Chuff Pipe
May we present the “Nielsen Chuff Pipe”, designed to give a really loud chuff when fitted on an Accucraft Superior, but the basic design could be adapted and altered to suit other Accucraft locos. Although the drawings state the size ratio, the drawings shown here may not be exactly to size in you browser - Therefore Frede Nielsen has produced an Adobe .PDF file which is available to anyone interested in using this design of chuff pipe for their loco.
Measurements in Millimetres.
