He then dropped to a more realistic level of presentation, starting with a single turnout, extending track in both directions along the main line, adding another turnout to create a crossover, adjusting curvatures, saving various stages as new templates.
After a break for refreshments, we moved on to discussion of practical trackbuilding. Unfortunately most of Richard's jigs had apparently been mislaid during his escape from a waterlogged Traction Engine Rally at Bedford the previous night, but I was able to provide a range of examples (all in pristine condition). The main part of the demonstration followed on from the Templot start - put double-sided tape onto a printed Templot turnout, add sleepers cut to appropriate lengths, then chairplates and appropriate rails.
There was also some discussion and demonstration of alternative approaches - using Association base and templates for PCB sleeper-based turnout, and using milled bases for Easitrac-type turnouts. We finished with a brief discussion of tiebars/TOUs, with the moving sleeper method being recommended.
Plans for the near future:
Next meeting, Sunday 17 November, has been replaced by an MRC Open Day, 2FS and N gauge, with all members of the London Group invited to come along and "play trains" for a while. Copenhagen Fields, Lambourn, Llangerisech and the Central Shop should all be present.
Sunday 19 January will thus be the next conventional meeting. Provisionally scheduled as a "Show and Tell" session - bring along your current projects to talk about them, or just have a general chat.
PS Apologies - uploaded photos weren't displaying earlier. I think the problem is solved now - they don't do justice to the examples of trackwork on display, but they are (I hope) better than nothing.
