Well its finished and I think looks looks rather nice all built to the diagram in Peter Tatlows excellent book. The added "extras" to the ends are the strapping at to top of the end beams and the righthand handrail, neither of which are specified in the build instructions. Cost £55 for the basic kit, Markit wheels £8+ and Haywood buffers £6.75 all up rather expensive. So the real question, was it easier building the chassis first, before joining it to the body, which was the purpose of the experiment. In many ways yes, access to the chassis components is definitely easier when you can work from above and below but also there are very few components which cross over from the body to the chassis. Would it work if there were significantly more , I'm not sure.
