Progress of a Coal Fired PYRTE during construction
Nothing decided for a name yet, so PYRTE - CF fits the bill for now!
This two inch scale steam engine, a model traction engine, will be using the original boiler arrangement of the gas fired version of PYRTE, lengthened a little and modified to allow better support of the pressure barrel and steam raising, still very simple to make but all encased in a steel outer shell at 30+ inches long and weighing??? (we'll see when she's up and running).
The intention is to produce a very economical build as well as an easy to make passenger hauling model traction engine and run her at 75lbs/sq.inch rather than the original 50 of PYRTE, and also have a longer stroke to accomodate the larger diametered rear wheels. There will also be a crank driven water feed incorporated, as well as the hand pump used on the original gas fired version.
The rear wheels will be solid centred for ease of constuction, moving on later to a spoked wheel version to make it look more the part, as these are available commercially in the right diameter for this model steam engine.
These pictures show a general run-down of the construction starting in January 2013 and will possibly take some time owing to the modifications along the way. That, and waiting for bits to arrive if I'd not thought ahead early enough, along with writing the instructions for the build.
