Some years ago I saw an article in one of the model railway magazines in which the author had repositioned the motor and built a new gearbox from Squires gears, spindles and driven by a biro refil tube. I had saved this article to get round to copying. Now I've got the gears and spindles and can't find my copy of the article. does anyone else have knowledg of this subject and can you help me with the details please.
