Re: Richmond two cylinder compound locomotive for Sweden

Hello Hudson, Nice photo of an ancient locomotive and cylinder casting! Those 2 cyl. compounds had been very common here in Europe until first WW. To make starting easier there were some devices to change over from single to compound mode. Most popular with several types (P 4, S 6) of the Prussian S...

Re: A with Timken running gear

News from my A Hello steamers, it took me some time to complete the framework and cylinders, shown before in some other posts. Now the Timken running gear is complete, too including the crossheads. The construction may be of interest for some others who think about roller bearings (ball bearings) fo...

Re: Interesting project

All those fine castings are great! But for just one single locomotive built from scratch there are more methods to do the job without CAD, CNC and a foundry at hand. Please see what you could do by just means of milling, turning and tig-welding during the 1970s and 1980s. Wheels were a casting job, ...

Re: waterjet or barstock frames?

As example what you will get by just laser cutting, please see the frame of my A project for 5 " . The frame was built as a sandwich construction of 2 plates of 5 mm and a third (different) plate of 6 mm made of stainless steel. The overall accuracy of those lasered parts was within + / - 0.1 mm. Th...

Re: Throttles on Artculateds

Mr. “Asteamhead”: Are you building an A-class 2-6-6-4 in 5” gauge? I assume you know of the beautiful 7 ¼” gauge 1218 in Switzerland? I see it on U-Tube. When do you get done – wie bald sind Sie fertig? So “steamchris” is the son of the good man with the 5”-gauge Y6b? (I guess I know his real name....

Re: little steam pump

Hello, Nice working pump which will feed water against twice (!) the steam preasure. It is a small closed feedwater economizer in the water connection to the boiler, isn't it? Maybe your'e a bit optimistic regarding the amout of water to be pumped per min? I would estimate about 0.1 l per minute whi...

Re: Throttles on Artculateds

Nice Question, indeed! This is exactly what I have in mind for my N&W Class A under construction yet. Instead of two throttles the idea is to divide the steam passages directly behind the throttle for saturated steam. The front wheel set will get the steam via 1/2 of the superheater from just one si...

Re: 4-Cylinder Pacifics in Britain

Hudson, you're right perfectly! There was just another reason for having 2 + 2 cylinders working in parallel: They just needed 2 independent valve gears. The connection levers were another story yet. The two inline cylinders were hidden inside the fabricated frame made of steel plates perfectly - no...

Re: Fuel consumption

Any amount of oil will evaporate 10 to 11 times that amount of water. Coal will just do so with about 6 to 7 times. Thus your tank volume of just 2 gallons would drain your water tank two times between fuelling, don't worry!

Re: Cylinder bore and stroke question ...

Hello George, May I help you a bit by a simple formula: Tractive force TF at the wheel rim is eaqual to the total displacement volume of all cylinders during one full turn, devidedby the circumfence of the driving wheels and multiplyed by the effective average preasure in the cylinders. With our mod...
