  • Page 2: Section 1: Brief Historical Details

    SECTION 1: BRIEF HISTORICAL DETAILS For a detailed history of this large (156 engines) and long lived class Part Seven of 'The Locomotives of the Great Western Railway’ published by the R.C.T.S, is essential reading. From this kit any of the straight framed engines (the last 115 built) can be built from circa 1904 to 1951.

  • Page 3: Section 2: Chassis Details

    Having decided which chassis to construct you can now start construction by preparing the inside frames, (parts 1 & 2) If you are building a 'Bulldog’ with steam brake, first modify the rear of the frames by shaping to the half-etched line.

  • Page 4: Section 4: Frame Spacers And Assembling The Chassis

    A for compensation beam pivot - 1/16" C for steam reversing cylinder mounting pin (only if you are modelling a 'Bulldog’ with steam reverse) The last job on the frames is to emboss the rivets marked by half-etched holes as shown on the diagram.

  • Page 5: Section 6: Fitting The Flexichas Hornblocks

    Solder 0.45mm wire through frame holes B to form the brake hanger pivots. Use the upper of each pair of holes for a 'Bulldog’ with steam brake and the lower holes for a 'Bird’ with a vacuum brake. Remove the sections of wire between the frames.

  • Page 6: Section 8: Bogie

    SECTION 8: BOGIE There are several bogie options available and careful study of appropriate photographs is needed before you start. The options are: Many different rivet patterns - emboss those wanted Shallow or deep frame - shape the frame up to the half-etched line on the inside for the shallow frame Strengthening patches Splashers below the frame - remove for later period Swing hanger suspension or De Glehn type - omit the swing hanger castings for the De Glehn type...

  • Page 7: Section 11: Outside Cranks And Mechanical Test

    Any piece of 0.012" material placed on top of the frames will help ensure correct alignment. I found part 108 ideal. For a 'Bulldog’, first shape the rear steps to the correct profile, depending which lot you are building, as shown in the diagram.

  • Page 8: Section 13: Finishing The Chassis

    Note the cylinders are handed. For a 'Bulldog’ emboss the two rivets on each outside rear brake pull rod (parts 35). Now fit the brake pull rods (parts 30, 31 & 34) using 0.45mm wire as shown in the diagram. They are also attached either side of the steam brake cylinders.

  • Page 9: Section 15: Firebox And Boiler

    Solder the splasher fronts (parts 73/75 & 74/76) to the footplate edge so that their bottom edge is level with the bottom edge of the footplate side. Curve the splasher tops by rolling underneath a suitable rod or dowel on a soft surface - a piece of rubber sheet or carpet, and solder them in place.
  • Page 10 If you are fitting the three quarter cone (D3) boiler remove the rear section as shown in the diagram by scoring adjacent to the boiler band with a sharp blade and then breaking by bending. Then file clean the edge and drill two new handrail knob holes.

  • Page 11: Section 17: Final Detailing

    I hope you enjoy building and running your 'Bulldog’ as much as I have enjoyed researching and designing it. Finally I must thank Paul Garnsworthy for the superb drawing and Tony Reynalds for many of the exquisite patterns for the cab fittings and the boiler fittings.
