Construction starts with the running gear. After separating the W-irons, axle boxes and solebars from the sprue, some cleaning up will be needed. According to the instructions the builder locates the axle bearings in the holes in the W-irons, and attaches the axleboxes to the rear. When this was attempted with waisted bearings there was too much slop, and shouldered bearings were found to be a better fit. It was, however, a bit fiddly to get the axle boxes to line up correctly; they need to be vertical and line up with the shackle on the leaf spring (which is on the W-iron moulding). If the model was being built with a compensated or sprung chassis, this design might be a considerable aid to the modeller. |
Wheel bearings inserted into the W-irons |
The next stage is to attach the W-iron mouldings to the back of the solebars. The solebars have a circular pip lining up with a hole in the bar at the top of the W-iron mouldings. The top edge of the solebar and W-iron units may need some cleaning up with a file.
The solebars can now offered up to the floor. I found that the solebars were longer than the floor. I trimmed the length, but it is important to make sure that the axles will be parallel and equidistant from the centre line of the floor. Later in the build I realised that trimming the solebars was a mistake – the body fits around the floor and the headstocks should be a little clear of the end of the floor. |

The headstocks are tackled next. The instructions suggest that scale couplings should be fitted to the headstocks at this point. In order to fit the scale couplings I was using it was necessary to slightly elongate the hole for the coupling hook to pass through, however care is needed as the enlarged hole significantly weakens the headstock.
After attaching the headstocks to the ends of the solebars, I fitted the buffers. There are small collars that fit onto the buffer shanks. The collar is threaded onto the buffer shank and then the buffer shank is inserted into the buffer housing moulded on the headstocks. |
The assembled underframe before the brake units are fitted |
The body consists of four parts, two sides and two ends. These are assembled around the floor. On the inside of the body parts there are ridges, these should fit against the floor, not sit on top.
These wagons were fitted with Morton brakes, but brake rigging only on one side of the wagon. The kit is designed with locating pips on the brake rigging unit, these are supposed to fit into holes on the underside of the floor. Two sets of two brake rigging units are supplied with the kit. The units on the underframe sprue appear to be for DC brakes, those on the body sprue are the correct units to use (but only one is used).
I found that the holes were too far from the solebars, and that the brake blocks fouled the wheels. To correct for these problems I removed the locating pips and positioned the brake rigging unit by hand. I also needed to file the back of the brake blocks to ensure the wheels would turn freely.
The two brake levers are the next parts to be fitted. These needed some slight cleaning up. Finally a piece of plastic rod is fitted between the V-hangers and the back of the pivot in the rigging units. |
