The HR TPO has proved to be a great learning exercise. In other words lots of trial and error, recriminations, reworks and inevitably more time taken.
Towards the end of the month, as I was trying to finish the roof and starting to plan the underframe, I mulled over the thicknesses of brass I might have to use. Thinking of my experience at Missenden Abbey with 0.8mm nickel silver rods, the penny dropped and I ordered a job lot of nickel silver wire, rod and solid sections. I guess I’d been using brass for these items because that seemed to be the thing to do, though it’s a very long time since I used brass for bodywork other than in kits. But isn’t nickel so much easier to solder? What’s the advantage, for example, of brass wire over nickel silver?
TPO nearing completion
My focus will soon turn to bringing 14 coaches up to a consistent standard for photographing and exhibiting. In order to make up a realistic sequence of trains, I particularly need to standardise on draw bar hooks, couplings, buffers, gangways, underframes, bogies, and the general level of internal and external detail.
I’ve already done the difficult bit by creating a spreadsheet.
