Thanks Steve (and to everyone else who clicked the 'like' button; I'm glad someone is following this!). Another vehicle on the go - and you can blame Modelzone for this as well - is rather more involved and pushed at the very end of my modelling period. This suitably Western Thunder friendly image should give you all an idea.

Paul Bartlett, as is so often the case, has a gallery (and my heartfelt thanks - this resource makes modelling wagons much, much easier):

The raw materials are a Bachmann 'TTA' chassis - in fact from one of a pair of heavily reduced Modelzone special edition spoil carriers - and an ancient Tri-ang model of the Clayliner tank. Why on earth Tri-ang chose this prototype I cannot begin to imagine since there were fewer than 20 of the things and they operated of a reasonably restricted flow between Burngullow and Sittingbourne, or from Burngullow to the Potteries. Still, they make for a nice blue tank wagon and it isn't impossible that they made their way in ones and twos on occasion. Besides, they were air-brake only and this makes an interesting change as a project. So far as the tank is concerned, all I have done so far is to remove the stickers and the tampo printed lettering before glue the tank together and filling all the various sink holes and making good the joins. I have also removed the pedestal and made a new one.
It's the chassis that needs the work, however. Monobloc tanks are subject to phenomenal amounts of variation in terms of things like spring hangers, vee-hangers, brake levers and the positioning of various components although the solebars, W iorns and axleboxes are reasonably uniform. I've only really got as far as the vee-hangers so far but I'm quite pleased with them so here we are. These are mounted on the outside of the solebars (Tri-ang got these about right) so had to be changed. I fretted them up from scrap etch - three layers, soldered together. The holes were marked out on a 20 thou' plastic template since this is easier to mark out than brass and the template superglued on top.
The lousy image above shows the sandwich and the now discarded template; The holes in the brass were done using the trusty Dremel. I'm only doing the one, if I wanted a rake, an etch would be called for. Below is one of the vees fitted with pins (I used the vee itself to mark out the solebars for drilling):
Finally, here's the finished item:
As you can see, the next step has to be the spring hangers before the links between them and the springs break and disappear from repeated bending.
