No castings were harmed in the construction of this pump
Having a few blocks of bronze in my armoury, I determined to have a go at making the pump without the use of castings.
I cut slices from the round bar and silver soldered a spigot to the rear, so that they could be held in the lathe chuck. Three of these provided the base and the two cover castings. It was recommended to me that the pump would be more robust with a third pillar between the steam cylinder and pump and the round slices provided the scope to do this.
Those tiny fiddly steam valves!
Equally fiddly glands. Glued together as a pair.
The complete set of parts. I found an old Kennions cover casting, that was too good not to use.
The bronze parts
The stainless steel parts
It is easier to set the timing and get the engine running, before attaching the pump.
