Gents, there is a link on my page called locomotive engineering <http://www.archive.org/download/locomotivebuildi00flanrich/locomotivebuildi00flanrich.pdf> http://steammechanic.googlepages.com/home That link leads to a pdf download, containing N° 79 to N° 84 of "machinery's secrets" This file contains all you need to know about the building of a full size steam locomotive. I will leave the link on there for now, so please download the file when you can use it. It is 35 megs, so the use of a download manager wouldn't be a bad idea. The quality of the pdf file is very good Cheers Patrick MODEL ENGINEERING DISCUSSION LIST.
