Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

Update: My engine is in the airlines hands at this time, possibly a week yet.
    In the mean time I enjoy watching others discover the difference of how this new model is built.
  The video found on YouTube is interesting, this guy's engine was delivered with a non working governor, he has it working now though not as well as would like.
  The other interesting thing is he says the new cylinder liner is no longer stainless but some type of mild steel that will rust if plain water is used for cooling.
  Also his engine starts well but gets tight as it heats up? I suspect his engine could benifit from a bore polish but difficult to say from just watching the video.
  Also I found a different video where a guy had significant cylinder bore scoring from the wrist pin (old model) is this a common issue? I have considered tapping a set screw from the rear of piston (to keep wrist pin centered) if wrist pin scoring is a common issue...but there may be better ways to address this?
  Thought I would share the video as this is one of the best ways to learn about these engines.
