PaulC,
I suppose there was no reason why we couldn't have met and said hello. I apologise for not making the effort.
I spent most of my spare time picking the brains of two modellers, both with attic layouts, one modelling Lisburn. They were able to give me a wealth of advice on soldering and the technique involved. They even took the trouble to bring me to Squires Stand and help chose the best soldering iron (which turned out to be sold out). Don't know who they were but they were very welcoming.
Maybe next time......
