Starting on it properly and using the article by Adrian Gray in NG&IRM Review issue 42 as a valuable reference, it was clear this was going to test my soldering skills somewhat. It contains a myriad of tiny little pieces which often need to be attached adjacent to each other. My little used Graskop RSU came to the fore - in fact I defy anyone to build this kit without an RSU.
The kit was advertised as complete/unbuilt but unfortunately someone had rather crudely pressed out the rivets on all the etches but not really done anything else. I filed the rivets off the solebars and replaced them with tiny brass rivets pressed out of some brass shim and soldered on with the RSU, but it was clear this was not going to be practical for the rest of the kit. In the end I just ran over the rivets with my GW Models riveter and vowed to make it a very rusty finish. Construction followed the instructions and tips from Adrian's article. The hardest part was fitting the wheelsets, couplings and trying to represent the door pins and chains.
The bogies are scale width and supplied wheels are to 14mm gauge - it could not be built to anything wider. Even with drilling the bearings I could not get enough room to fit the axles so I ended up shortening the axles (by grinding one end). The wheels/axles need fitting at the same time as the whitemetal axleboxes which need to be soldered in - which is not easy. I ended up using pop rivets to fix the bogies to the body as this enable most of the brake gear to be represented. Fitting the brakes was quite a challenge too.
The bogie platforms are far lower than my standard coupling height. Internet searching showed this to be a problem on the prototype too and provided a potential solution of an additional platform as shown in wagon 74 on the Festiniog railway here: http://www.festipedia.org.uk/wiki/File:74.JPG.
I adapted a pair of my round couplers to pivot in a rectangular brass tube with a phosphor bronze centering spring and fitted a new brass platform above. Milliput was used to fill the gap each side.
Although it provides reasonable sideways flexibility it doesn't flex up and down so it will not run reliably over the whole of the PLR without occasionally uncoupling. I fear it may be banished to a siding and allowed to rust - it will need a bit more weathering if it is to match wagon 74!
Door pins and chains were attempted in very fine brass wire and fuse wire but probably don't bear close scrutiny. Perhaps the banishment siding needs to be at the back of the layout.
