A Garratt In Miniature
Doing things the easy way

From the start, this project was going to be a mammoth task, with lots of head scratching and hours of wondering. As I have a full set of drawings for the full size locomotive, I had a good start on the construction. Having spent the good part of two months learning TurboCad, work was started on translating the full size drawings to a usable 5″ gauge set. The main reason for using CAD was to enable a bit of cheating on the project!
Some model engineers will cringe at this sort of construction and the use of a laser to cut metal, but when you are presented will hundreds of curves, holes and intricate shapes which need hacksawing, milling and filing – I know what I’d rather do! And besides, the hacksaw I use tends to only cut curved lines, although i’m sure its not operator error!
Once into the swing of TurboCad, I found it a very easy program to use and one i’d recommend. It exports to .dxf, which is a standard drawing format used for laser cutting.
