       Refurbishing a model steam engine with a Scotch yoke transmissio
       n. Part 2.

       Hi,
       The second session of playing with my friend’s model steam
       engine has happened.  So far, we have been reasonably successful
       in using all the original components, only 7 screws being
       replaced.  As the engine has been moved on its baseplate to
       square everything up, most of the original holes have been
       plugged, re-drilled and tapped.  The mahogany base has been
       shortened and cleaned up, all the parts that make up the model
       have been cleaned and the crankshaft assembly has been fitted to
       the baseplate.  As the Scotch yoke and piston assembly are quite
       heavy lightening balancing holes have been drilled in the
       flywheel and the piston no longer drops from half stroke to BDC.
       Take care Tony.
