Hi Jem, Unless you like watchmaking, bigger models are easier to build. Smaller parts are generally harder to hold while putting on the high cutting forces needed in metal work. If you have a few parts beyond the size of your equipment, chances are local industries or other club members will have larger ones. I've found that if you show up to the back door of a machine shop at lunch time with a tray of coffees, and tell the guys what you're up to, they're generally glad to help, as long as you're not in a rush. When I was in the toolroom, training, we loved jobs like that for Friday afternoons.

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. > > Best wishes, > > Jem Harrison > Basildon > > > MODEL ENGINEERING DISCUSSION LIST. > > To UNSUBSCRIBE from this list, send a blank email to, > modeleng-request@xxxxxxxxxxxxx with the word "unsubscribe" in the subject line. > MODEL ENGINEERING DISCUSSION LIST.
