The Home Machinist!

No problem at all.
Look, many 3-cylinder engines had their valve excentrics and their middle cylinders at different axles. No issues, no further measures necessary.

Hello again gamh44,
I forgot to mention the 3rd tool from the right on the photo of your board. This adjustable grip nippers made by Facom or Gedore to me was worth it's weight in gold working at elder cars.

Hello gamh44,

What a pitty indeed, regarding we are living apart at such distance . Your engine would complete our ensemble perfectly!
We will watch your progress with great interest

Hello modelers (who are still using obsolete technics now and then), Talking to several life steamers, I detected a simple method to fix hexagon material in a standard 4 - chuck instead of using a 3 - chuck seems to be unknown by many of them? Shift the hexagon material into the chuck, turn it a bit...

NP317, thank you! Now some more information regarding steaming by means of the stoker. Pure anthrazite coal of high quality seems to be hard stuff for the stoker :? . I did some work to improve the coal crusher but still given coal size wasn't the best to be fed by the stoker. A steamer had develope...

Hello EVGEN, What about building this monumental giant of the former Soviet Union? Found these rare informations in a German magazine just recently. May be a thrill for you to construct and build this engine and make it run successfully as a model - other than the prototype, which failed? Seven(!) p...
