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 tools required are: Small Vice, Small Hacksaw, Screwdriver, Pliers, Wire Cutters, Centre
Punch, Hammer, Files, Drill and Drill Bits. A
solder torch is required to solder the Boiler.
The constructor will
also need to screw, glue, saw, drill, file and
cut various small, mainly brass, parts.
