Triple Expansion Steam Engine -The water pump
The triple will not be finished by Xmas. No chance of getting into the workshop while we are looking after 2 grandchildren. So the new aiming completion date is Jan 6, in time to run the triple on steam at the Geelong truck show. If I don’t meet that deadline, the next access to steam will be the end of 2017. I really do not want to wait that long.
So the next component to produce out of a chunk of gunmetal is the water pump.
There are two cylinders in the water pump. The gunmetal castings appear to be good quality.
Most of the machining will be done on the mill. But I need a datum surface, and have decided that the attachment plate is the most appropriate.
When I get back into the workshop I will machine the rest of the pump parts.
