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

Hi,

Well this morning it was cold and damp in Cardiff and while I waited for the heater in the shed to do its bit, I had a look at the beam engine.  I was a little concerned as the flywheel is a bit on the small side for a beam engine that would usually work quite slowly.  So, I decided to check how well the beam balanced; the connecting rod and crank on one side and the parallel motion and piston on the other.  Well by accident or design it is pretty well balanced, the crank and connecting rod being possibly a little heavier.  It is close enough that it is not worth weighting the flywheel to compensate until it has run and then it might not be necessary.  The piston and its rod are interesting the piston is screwed off not the big end to remove the piston rod from the cylinder cover.  Anyway, most of the day has been spent build the model railway layout. Work will only be done on the beam engine if I get time or get bored with working on the layout.
