Guys, can I please ask you to limit off-topic posts. Freelists, who host this list, do monitor all their lists and WILL cancel any list that they feel is not keeping to the subject for which it is intended. The occasional off-topic post is understandable, but let us keep it within reason. It would be a pity to lose this list just because of some banter. As for what is ON topic, anything related to model engineering, or steam or engineering matters, or even subjects that are linked to them are all OK. Thanks guys. alan@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx www.alanstepney.info Model Engineering, Steam Engine, and Railway technical pages. MODEL ENGINEERING DISCUSSION LIST.
