DEE
The Harry Wainwright
"D" class was built at Ashford works in 1901. It was a
development of the so called
M.3 class and was the beginning of the
new range of locomotives. It did some of the heaviest work until
1914
and in the first world war
1914-1918. In January 2001 the
"Gauge '1' Model Railway Association" published
"The DEE Book". And from there I
got the idea to
construct the twin inside cylinder 4-4-0 locomotive in G 1.
Construction
Report
The model building is finished
now
and it is completely dismantled for painting. Anyway the
report slightly shortened
is still here on the website. It is intended to give a
short description of
parts of the construction of the model
started on
02.01.02
 |
|
The start was in December
2001. The mainfraime (
stainless steel) with buffer beam, drag
beam and
completed and working axle pump is now mounted.
The
wheels are ordered in England (Mark Wood)
and still have to
be delivered. The finishing of the
cylinder blockis the next
job. In the picture is the
completed chassis.

The left picture shows
the finished twin-cylinder block
without front cover and with
trunk guides and connecting rods.
The lapping of the two valves
as discribed in the DEE-book
with half chambers was a hard but successful procedure
( about four hours time ).

2.05.02

|
The finished working chassis
with complete
inside cylinders, axle pump, lubricator and
front
buffer beam.

7.10.02

Now
the boiler: the silversoldering was
somewhat of a difficult
job. It is done now
and
the
test pressure with twice the
max. working
pressure was
successful.

yet
silversoldered.

Not yet finished but at
an advanced stage of the
building
1.5.03
There were many problems
besides the time needed: especially the tender axle boxes because
I had no
white metal castings
(therefore I had not the problem how to fix them to the side frames as
recently
asked in the gaugeone forum).
I had the opportunity and constructed real plate springs
and last
not least I made
ball-bearings for the axles. Now it's done and the finishing of
the
tender with hand pump and
gas tank is a
straightforward job I hope.

After a longer interruption it comes
true, 'the simple box on wheels' - the tender- is ready and is
going to be prepared for painting.

The painting is done. The model is finished, every part of
the locomotive works well
and
it is good to say, that especially the engine runs very smoothly.
A long way
from the beginning in February 2002 to the completion of
this nice model !
It
was a deduction and a challenge to build this beautiful small model as carefully
as possible. I can
recommend to everybody
to construct this model who has patience and endurance as well as the
necessary experience.
