Simon and Roger,
Thank you both very much for your kind comments.
Next instalment :-
Canopy supports added from angle section styrene with roof support beams from the same material. Hand brake tube is a piece of tube from point control wire in tube, engine exhaust is cut, bent and soldered up from brass tube and arranged to exit from the back of the loco.
The roof is constructed from styrene sheet and curved by taping to a convenient sized container (beer can?), filling with hot water for a couple of minutes then draining and filling with cold water to set in position. The engine compartment grille is a piece cut from an item bought from a local hardware shop many years ago, designed to fit on a frying pan to act as a splatter guard when cooking your sausages/bacon etc. Small rivets are formed using a rivet press from behind, the larger ones are short lengths of styrene rod glued into drilled holes.
Axle box and horn block detail is built up from odd sections of styrene sheet and strip, springs are coils of soft copper wire, these are placed on the under frame, then touched momentarily with a soldering iron to melt slightly into the plastic. Using this method of fixing the springs ensures more detail is retained, as opposed to gluing which tends to run into the separate coils and fill them up.
Painting next!
