My obsession with<\/span> interest in all things ex NBR continues.<\/p>\n

Last year I bought a selection of NBR underframe sprues from Parkside for scratch building wagons (this was before the Silhouette Cutter was even on the horizon. At the same time I also got a couple of ends from the 8 ton Jubilee van kit with a view to making one of the later Diagram 40B vans. Unfortunately when I compared the drawings the later vans whilst having the same style of ends were not only taller but wider too.<\/p>\n

So the ends went in the spares box and were forgotten about. That is, until last weekend when I happened to be reading the chapter in Vol 3 of LNER wagons and realised that the first few vans that the NBR built to D39B were not only low roofed but the same width as the earlier Jubilee vans – Bingo!<\/p>\n

The next problem was that although I have a few drawings they are all of the taller vans. Tatlow to the rescue. Although there isn’t a drawing, there is a pretty good square on side view photo, so I scanned and imported it into Inkscape. I resized it using the wheel base as the known dimension and essentially drew over the top of the photo.<\/p>\n

I have in mind to do some outside framed vans starting with and NER G1 van and decided that the external framed door on this one would act as a proving ground for doing them in layers. Initially I drew the doors as 6 layers of 20thou – 2 backing, 1 plank detail and 3 for the framing. Once I had snapped them out and compared them to my existing Parkside 8 ton Jubilee vans I came to the conclusion that 6 layers was too thick. I left out one of the backing layers and one of the framing layers and then proceeded to assemble the doors.<\/p>\n

On the other van \u2018kits\u2019 that I have done I have done sides and ends in 3 layers and have sized the inner 2 side layers shorter to allow the ends to fit inside the outer layer of the sides. I had to do it a little differently on this one because the Parkside ends are chamfered to a 45 degree angle. To get around it I made the 1st<\/sup> inner layer 0.5mm shorter than the outer side and the next one another 0.5mm shorter than that.\u00a0 It was a great idea but fell down in practice because it was difficult to spread Butanone on the layer and then accurately place the next layer central with a 0.5mm gap at either end so the next ones that I do will have a removable registration tab on them.<\/p>\n

I managed to get them together in the end and then using a broad diamond file (from the ladies manicure counter) I filed them to an angle that fitted against the ends. I took care to mark each side and end where they fitted together to make sure that they went back as I had filed them to fit.<\/p>\n

In the end I was really pleased with how nicely they fit against the ends bearing in mind that I had drawn the parts from a scaled photo.<\/p>\n

I had drawn the curved ended bottom runner and the plates that look a bit like birds feet in 20 thou to give them a bit more strength (I also cut some from 10 thou just in case). That left the runners themselves which are very much like pulleys. I hit upon the idea of putting a length of 2mm styrene rod in a pin vice and then using the blunt point of a round file to score\/pick at it to make a groove around it that would sit on the runner. I then used a scalpel to cut of the runner by rotating the pin vice and I was quite impressed at how cleanly the \u201cpulley\u201d was cut off.\u00a0 Since then I have thought of a refinement \u2013 grind a curved cutting edge on a piece of 0.8mm piano wire instead of the rather crude file point.<\/p>\n

Next I assembled runners and the door stops etc. on one side and glued it to the ends\/floor. At this point I thought I was onto a winner when the spares box also revealed a pair of spare Parkside sole bars but sadly they were too long and although I could have cut them down the wheel base was wrong too.<\/p>\n

Enough of the talk on to the pictures.<\/p>\n
