of Trevithick's Dredging Engine. In 1806, following on from his
'Puffing Devil' in 1801 and the Penydarren Locomotive in 1804,
Trevithick built a steam dredger for use on the River Thames
using his 'strong steam' engine. model is similar to the full
size original engine on display at the Science Museum and is
designed to operate as a live steam model. It can also be
operated by compressed air if you wish. Pressure: Less than 5psi
Double Acting Cylinder Dimensions: 220mm long x 150mm wide x
310mm tall (to top of chimney) Boiler Capacity max. Boiler
Heating: Solid Fuel Tablets. The kit requires no machining but
the boiler does require some soft soldering. The two brass end
caps need to be soldered into the brass boiler tube and two M6
nuts need to be soldered onto the boiler body. It should not be
too difficult to build by anyone with average tool No machining
or previous model engineering experience is necessary. Assembly
should be easily within the scope of anyone familiar with the
use of normal tools. The to
