1912 Hubbard Marine Petrol Engine castings water cooled model engineers workshop

This model represents an early form of marine petrol engine designed for inboard operation and is water cooled. Fuel was petrol and ignition was via low tension igniter. It is a conventional two stroke with crank case admission & transfer via cylinder ports. For the purpose of the model & to make it easy to build & operate it has been designed for glow plug ignition with the striker being replaced by the glow plug.

It is not a difficult engine to build but some may find lack of construction notes & exploded views challenging. These castings are foundry seconds, unfettled and still on the sprue (the turning spigot is damaged/not round).

Builds into a model approximately 140mm tall, 25mm bore, 25mm stroke. Aluminium castings :- body / crank case, crank case sides (2), intake tract, crank case covers (2) Piston (Ali), liner material (CI), flywheel casting (CI) & book of drawings. Ideal project for those with smaller machinery. Traditional drawings in metric & imperial. NB these are raw castings, the use of a lathe and other tooling will be required.

Please ask before ordering if you have questions.
