Based upon notes made and information gathered during almost 40 years of building models and working on steam engines, it is hoped that some of this information will be both useful and interesting to others.

This website "project" originated started during Christmas 2000 when I decided to put many of my hand-written notes, charts and tables onto computer.
One friend asked for copies of some charts, and suggested that they might be useful to other people.
I mentioned one of them on the model engineering list, and the response encouraged me to make them more widely available.
From that point on, this site has, like Topsy, just "growed

The charts can be printed and laminated to withstand use and abuse in the workshop.
Some of the content is very old and is probably outdated, but may still be interesting, if only to see how things were done in the past.

As the information is from a wide variety of original sources,

Model Engineer magazines.

I have a large number of spare copies of Model Engineer magazines. At the same time, I have numerous gaps in my own collection.
If you are in a similar position, please contact me for a list of my wanted / spares and lets see if we can
arrange to swap issues.  (Contact me at  alan "at" )

I have 24 copies of Old Glory, dating between 1993 and 1998. Available for swaps with ME's from my "wanted" list, or best  offer. Contact me for details.
