Model Engines on Steam

It is Geelong Show time again.  It is actually titled the Royal Geelong Show, but having had more than a gutful of royal non-entities visitors being adored by unthinking cringers, flocking around Harry and Meaghan Kardashian, Windsor, and being a committed republican, I refuse to bother with the “Royal” handle.  (they are probably very nice people, I just cannot stomach the hoo-ha).

More importantly, it gives us steam junkies a chance to run our small engines on real hot steam.

For a treat, I am sharing four short clips taken today.

The first is a small beam engine, made by Swen Pettig.

The next two engines you have probably seen before.  My beam engine, and the triple expansion engine.

The small engine to the right is a Stirling engine which is running on the heat from the exhausted steam from the beam engine.

The triple is leaking a bit more than it should, although it is running amazingly smoothly on 25-30 psi.  The valve glands need repacking.

And finally, a model IC engine, the really odd Atkinson.  A 100+ year old design.  2 stroke. Made by Rudi vanderElst

 

MODEL ENGINES in the cage at the GEELONG SHOW

The following short videos show some of the engines on display by GSMEE in the Vintage Machinery Shed at the recent Geelong Show.  GSMEE is Geelong Society of Model and Experimental Engineers.  All engines are running on steam, except of course the Stirling engine,  the Farmboy, and the Atkinson engine.

These engines will be running again at the GSMEE exhibition 25-26 Nov 2017, at The Lifestyle Pavillion, The Geelong Showgrounds.  Several scale model traction engines, trade exhibits, outside entries, and the engines in the Vintage Machinery Shed will also be on show.  The Hatherly Challenge competition will be judged.  This year the challenge is to make a reversing horizontal mill engine.  Entry is free (gold coin donation accepted with gratitude).
