results.The number of attempts was not always the fault of the template, I had to heat the card to form them and sometimes the heat didn’t produce the effect I wanted. However, with patience I obtained the components I wanted to finish the basic form.
K.A curved piece of 30 thou plasticard completed the roof of the cab and a 10mm strip of the same stuff created the exposed wall of the coal bunker.
L.The original locomotive had flanged boiler wrapper sections so to replicate this on the model I used 30 x 30 thou plasticard strips glued to the boiler.To get them parallel I made another paper template.
M.The smoke stack is made from a circular plastic collar from a light fitting. It required delicate heating to reform it into the oval stack shape for the loco.
N.The smoke deflectors were made from 30 thou plasticard cut to shape using a card template so that they would be identical.
O.I added ribs of 60 thou plasticard to form the pilot beams at each end of the soleplate. I used three sections to give the coupler mounting position then tapered the pilot beams from the centre to the edge.
2. Details
As this locomotive is 7mm to the foot any details I wanted would have to be either imported or handmade.
A.Whistle
The whistle is made from brass tube and plate soldered together. A copper wire has been added to simulate the operat- ing rod.
B. Headlights
The headlights are made from brass tube and plate soldered together.The plastic lens was added after the light body was soldered to the bracket.The exhaust for the turbo alternator can be seen in front of the smoke stack.
C.Steam traction motors and steam pipes There are four steam traction motors on the model, each was constructed from brass tube and plate. Each has a support pedestal that connects it to the bogie frame.
The steam feed and return pipes are aluminium bar. Each is connected to the appropriate bogie centre and the steam chest just under the cab.The ash pan can be seen just in front of the steam chest.
D. Foot steps, poling pockets
and hand rails
The Footsteps were made from brass rod and the step boards are wooden strips cut to shape.
The poling pockets are copper wire bent to shape.
