This is the boiler feed pump I've been making for the Simplex Loco I'm finishing off. Its to the improved super simplex design that has larger feed galeries and a different arrangment of return valves making it more compact, it's a double acting pump.
Drilling the and tapping the body
Measuring the height of the ball valve
Setting the ball down onto the seating by giving it a sharp square biff.
The parts off the pump exploded out.
I still need to fix the pump into the loco frame.
This is the eccentric where it has to be linked to.
Stand by for updates
