Here is another 'new' topic, on which I would appreciate your opinions. I am a relative newcomer to model engineering. I have no engineering background. In the distant past I have scratchbuilt models in 0 gauge (2-rail electric) and some wagons in Gauge 1. I have a Myford ML10 in reasonable condition and a small bench pillar drill (rough!). For the best part of the last three years I have been doing some restoration work on a Dore Westbury Mk.1: surgery on the motor, fitting new lead screws and nuts, devising different ways to attach the handles top the lead screws, making a drawbar, making a machine vice kit. It has been a long learning exercise! I now have some digital read-out bars that I have not succeeded yet in fitting....I do wonder if these are really worth the hassle. I want to get started on a locomotive. Until recently I reckoned that I would tackle something in 3½-inch gauge, but the vast majority of the received wisdom has advised against this size. So, what I would be interested to read on this discussion group is your views for and against 3½-inch and 5-inch gauge, oh and while we are about it, we could add 2½-inch gauge.
