Re: Attention all 3.5" steamers!
On that list that I quoted from, all the models up to 3_1/4" gauge were shown as either spirit (methylated spirits) or occasionally petrol (gasoline) fuel. Some of the smaller ones were clockwork, and one or two even hauled passengers with clockwork motors. Electrical power was tried, usually d...

Re: How fast this one?
The "singles" of which the most famous is probably that designed by Stirling, gave very high speeds (for the times) with a low piston speed, which was thought to be important, and without the complications of coupled wheels.The latter were compared to a horse with its legs tied together, a...

Re: A question about crown sheets.
In early engines, some were curved to a greater or lesser degree.
Some even had corrugated crown sheets.
At the end of the day, simplicity won out over other ideas.

Re: Old Stuart Catalogues
I have a feeling that it was dropped when Stuart's were sold, and if so, and if my memory is correct, it was in production throughout the H-on-T days, until Stuart's went to Guernsey.

Re: Old Stuart Catalogues
I have two catalogues that list it, both from the "Henley-on-Thames" days.
One (undated) shows prices in £p so was post 1971.
(On the inside back cover, Coles Power Models were listing their "Golden Anniversary Catalog" for $3.00)
The other is dated September 1983.

Re: Copper Boiler Design
I am pleased to see some attempts by various people to give some meaningful numbers to model loco boilers. Jim Ewins work was excellent and gave us a decent basis to work from, but with limitations (As Carddo said). Gathering the information required to cater for other gauges & scales, would be ...

Re: Annealing copper for boiling building - question
Copper is a wonderful material for boilers. (Apart from the cost!) When first made it will be annealed from the heat used to silver solder it. Do a pressure test, or steam it for the first time, and it will expand slightly. That will work harden it, and you soon end up with hard or half-hard copper....

Re: Copper Boiler Design
Some of the most accurate and detailed work on boiler (and loco) design was done by Jim Ewins. His articles were on the Internet, but you will need to search for them. His conclusions on boilers were tested and checked by the late Prof Bill Hall, who found that his (Jims) formulae were valid within ...

Re: Testing Steam Gauges
I feel that everyone should have access to some form of standard, that is KNOWN to be accurate. Now, whether that is a calibrated gauge at their club, a dead weight tester or whatever, is unimportant. What does matter is that they can be sure that thir "usual" gauge is accurate. Now, calib...
