On the whole issue of 3.5" gauge versus 5" gauge, I've heard several people comment that they tried building a 3.5" gauge loco, then tried a 5" gauge loc and found it easier - but might this not be because of the experience gained in building the 3.5" gauge loco? Has anyone out there started in 5" gauge and then gone to 3.5" gauge, and if so, what are your opinions? Yours (working in 3.5" gauge and finding it just fine), Rich. PS You commented that you had looked at the Sweet Pea design, but this is available in 3.5, and 7.25" gauge as well as Sweet Violet and Sweet William. MODEL ENGINEERING DISCUSSION LIST.
