The sligtly different feed pump.

[Michael S.]

Hello folks,

I needed a feed pump for the Stuart 5A. I also know that Stuart makes the correct pump as a cast kit.
But I couldn't get a set of cast parts at the time and wanted to build a pump myself. In old books there was a drawing for a pump for original steam engines of all kinds. What I didn't know now was the diameter of the piston and I decided on 12 mm. Maybe a little too big. The housing was to be built as a >cast part<. A mix of hard and soft soldered brass parts. The drawing served as a free template, without sticking to the dimensions.

The housing is made of brass and since the pump should last forever, the piston slides in a bronze bushing that has been pressed into the housing. The stuffing box also has a bronze bushing. The piston is made of stainless steel.

That's a great looking pump, Michael. Beautifully made!

Very nice work on the pump!

Thanks Ron and David,

The valves are normal stainless steel balls. So that they don't take off so high, there is a basket above it with a screw for limiting the travel. The balls sit on interchangeable bronze bushings. Both valves are so equipped.
Above that is the air bubble. I don't know what it's called in English now. In Germany it is called " Windkessel ". ( air chamber )
Finally, everything is painted and attached to the machine.

Well made and beautiful result 

I was going to ask if this is a 'Result off the New Workshop' - but the last picture made me think that  this is another build from before you joined here ....

Hello Per,

you saw that correctly. The construction is not current.
already a few years old. But I found the pictures on the computer yesterday and wanted to show them. I think I've shown them before in the German Steam Model Forum. I still have some construction reports from the past few days.
The pump is still doing a good job.

The workshop is finished and ready for new deeds. But there is still a lot to do on the house and farm.
I think autumn is the time for steam engines again.
