I have just seen that Dave Gingery died back in May. Many will have seen his books, which gave excellent and detailed information on many aspects of model engineering, workshop techniques. They are well worth reading, even though, quite naturally, they are American based, with US terms and, for example thread sizes mentioned. Easy enough to convert to English and British threads, or even them strange Millipede thingies if your so inclined! . alan@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx www.alanstepney.info Model Engineering, Steam Engine, and Railway technical pages. .
