When we made tapered coffee pot spouts in Denmark and other small
tapered objects we would first coat the item in rouge powder wet
with alcohol both inside and out, applying a thick layer to the inner
surface and the edges. We would make the cone somewhat longer than
the final spout would be then close the smaller end we would fill
the ‘spout’ with lead then bend to the required shape before
carefully melting out the lead. Which generally just fell out once
the surface had melted. No problem! If you look at my Ganoksin blog
’On your Metal’ there should be a very smart method for making a coil
of chenier using the drawbench. Taught to me by an old London
silversmith.
