    WOW PGH ! This looks superb. The 3/4 view with the buffer beam resplendent with bolt heads and rivets is the knock out !

    Thanks for sharing with us earthlings.

    Moving on to the two pairs of scratchbuild frames, the first job was to solder the inner and outer frames together

    The two sections were aligned with aluminium blocks machined into a "T" shape to fit both slots
    Next job will be adding all the bolts and rivets.
    With the addition of the etched chassis this build has now expanded to three locos, not sure yet which the third loco will be, but it will be Giesl fitted and possibly one of the Walkden "R"s - RESPITE, REPULSE or REVENGE

    After some deliberation the favoured prototype for the third Austerity is RESPITE, which is the one I saw and photographed most often in Lancashire and Cumbria.

    RESPITE at Astley Green
    RESPITE was ex works from Hunslet on 26/10/1950, arriving at Walkden Yard two days later. The name is a mystery. It was one of a batch of five obtained new from Hunslet by the NCB and delivered to Walkden Yard, the other four were named after Royal Navy battleships - RODNEY, RENOWN, REPULSE and REVENGE, but as far as I know there is no RN battleship or any other RN warship named RESPITE. It remained on the Walkden System until its closure, after the last train ran on 2/10/1970, working from either Walkden Yard or Astley Green loco sheds. It was fitted with an extended bunker c1959, which was removed and a Giesl ejector and underfeed stoker fitted in Walkden Workshops during November/December 1965. RESPITE was ex works in January 1966 in red livery lined yellow, replacing the previous black lined yellow. During this conversion it was unusually fitted with a small adjustable vent in the smokebox door, presumably a Walkden experiment copying the similar vent on locomotives fitted with the Hunslet gas producer system and Kylpor exhaust, but not repeated on any other of their Giesl fitted locos. Reproducing that on the model might be a challenge.

    After closure of the Walkden System RESPITE was stored at Walkden Yard until November 1972 when it made a 2 day trip by low loader up to the Ladysmith System at Whitehaven. Two years later in November 1974 it was damaged in a runaway, and then returned to Walkden Yard for repairs the same month. The repairs extended into 1975, but were completed by June when RESPITE was in steam at a works open day. Shortly after it was transferred to Bickershaw Colliery. The front part of the Giesl chimney had been patched up with a new section with square corners, the cast nameplates replaced with the name painted on flat steel plates and a new smokebox door provided without the adjustable vent. The last record I have of it working was in July 1978, on all my visits after that date it was out of use stored outside the loco shed.

    RESPITE and GWYNETH at Bickershaw in June 1977​

    RESPITE and GWYNETH were transferred to Resco Railways Ltd. in 1981 and parts from both used to construct the replica GWR 'Iron Duke' locomotive. The replica incorporated the boiler, cylinders and motion of GWYNETH, but only minor parts were used from RESPITE which remained largely intact. It was later sold for private preservation and is currently undergoing long term restoration at the Ribble Steam Railway in Preston.

    then there were 3......

    Did I really need 3 of these locos ? :confused:

    So far there's a total of 456 pins filed to represent bolts or rivets been used, and I haven't finished yet !

    Agreed. There is No Such Thing as "too many locos". Especially if they're a particular favourite, as well. :)

    Comparison of etched (top) and scratchbuild chassis. In retrospect I would have used the brass Slaters hornblocks on the scratchbuild frames had they been available when I started this project

    The triangular gussets between frames and buffer beams have been carried through from side to side and located in slots in the frame ends to ease assembly. In the etched chassis I've ignored the corner cut out for the 6" angle between frame and buffer beam and taken the gusset straight through along the back of the buffer beam, as the intended recipient for the final version of the etch didn't want to do the riveted angles and flanges in the corners. I've incorporated these in my test assembly by splitting the angles above and below the gusset. I don't think the lack of a triangular gap in the corner of the gussets will be too obvious in the finished loco.



    3. Chassis.jpg

    Moving back along the chassis between the frames, first is an angled plate representing the back of the cylinders, then the motion plate and a 3 part cross member just in front of the firebox. Dummy top slidebars and valve rods may be added later as a separate unit, and holes for fixing this have been provided in the cylinder and motion plates.

    The bolts on the buffer beam are as on the prototype, so don't line up with the narrower frames on the model.



    4. Chassis.JPG

    The riveted angles and flanges were added after the frames were assembled, so not really practical to use pins. Rivets or bolts were formed by half etching or a rivet press, and the parts fitted with an RSU. Some tidying up of solder joints is required, and the chassis will be grit blasted in due course.
