Hi Pete,

there is also a very fine Feed water hand pump designed by David King.

I will build my pump according to this design. For the individual parts, I will use gunmetal plumbing fittings. The basic specifications are as follows:
- Bore 26 mm,
- Stroke 90 mm.

Hi Bart,

thanks for your thoughts. My initial goal was simply to demonstrate how the valve needle is moved. I've already done some thinking.

I'm currently considering which burner design to install on my large OFELDT boiler. The LUNE VALLEY design is certainly appealing, but the addition of ...

Hi,

here are my thoughts on the design of the valve adjustment mechanism. The adjustment slide features an inclined square section that slides within a corresponding cutout in the valve, thereby opening and closing it to varying degrees.

Hi Trevor,

can you post some dimensions of your burner? It will be very helpful to design one in CAD.

Hi Markus,

a very interesting engine.

You can built a pump unit with a condensate pump in the middle and a boiler feed pump a the right an a circulating pump at the left side. Or you split it to every crosshead.

I have calculated the dimensions of the boiler feed pump as follows:
Bore 8 mm
Stroke ...

Hi,

Yesterday, I successfully tested the steam whistle - using the appropriate whistle valve - with sufficient steam. I like its sound.

Hi Wesley,

thank you.

Yesterday, I tested the newly built whistle valve under steam and checked that the steam whistle setup was correct. That was successful.
And since the boiler was already up and running, I also tested the throttle valve with steam. That worked very well, too.

Hi Kelly,

i'm glad you like it. I hope that applies to the now-finished valve as well.

This is what the valve face looks like. Thanks to the pointed shape, the steam can be metered more precisely at small valve openings, allowing for better control over the engine's operation.

Hi,

i have got a STUART #1 from a ebay UK. It was described as built at a high standard and should run well with compressed air. I have it checked and was like the Queen - "not amused". So i have it comprehensively overhauled.

I wanted a separate throttle-valve on the engine, and the design was ...

Hi,

if the eccentrics are only clamped onto a shaft with setscrews, two should be used offset by 90-120°.
