Technical information

I have collected some interesting items of information regarding Stationary Steam Engines over the years - a subject without a lot of current day publications dedicated to it - where possible I intend to post some of the less well known here, along with explanations of some of the items which appear on this site, building a 'reference library' as time and webspace permits.

Any substantiated corrections or additions to material posted here will be gratefully received
