Reply To: Merryweather Steam Fire King self propelled

[Werner SchleidtParticipant @wernerschleidt45161]

Hello all,

here is an update of my activities. We had our steam up at my local club the DBC Rhein-Main. The street steamer had now a new colleage with a traction engine. And a new setinel " elphant " made it first rounds in the public and I had my partly improved Fire King with new donkey pump and automatic blower valve and I added a small car for children to sit on. There were a lot of steam and electric locos on our club track.

In between with lot of improvisation I made my first real test with my measurement unit with the dyno and the pulse wheel and so on. There is a picture of the raw data on the quick look display on the phone.

The green line is speed and the white line is the dyno force. As I know now there is small lash in the coupling bolt and the road surface looked smooth ,but because of pavement it is rough with some noise in the dyno .

This chart is the averaged raw data of the dyno and the speed which is calculated from km/h to m/s to calculate the power in Watt. See next chart.

By the first shot I think it is not bad ,but I have some idea for refinements.

There is a video of the steam up at out club area.

I hope you can enjoy the video.

best regards

Werner
