Hi Jurgen,

in opposit to combustion engines, steamengines can be overloaded, the steam in the cylinders gets more and more compressed. The result will be a very high steam consumption. Sometimes a steamloco with a heavy train got overloaded at a long ascent.
Today I got the new cogwheels. What a difference! It`s no problem, to hold 2 bar with paddleshaft revolutions of 80 - 100. The water swirl with 3 bar pressure is yet more than before. With gas and water one can drive the boat more than half an hour.

Last job will be the roof. In original it was made of fabric, I will make it of very thin (0,5 mm) plywood. Of course the roof must be fast removible.

Today I altered my home made ceramic burner. The sound, a very strong howling, was not acceptable. Now I drilled some holes for the air and the sound is completely vanished. The power of the burner is strong, more than the soldering burner.
Also both roofs are finished - next week will be the maiden voyage at the lake!

Maiden Voyage today afternoon on a sunny warm springday. All was ok, presentation of the boat was very good. I think, the model is well suitable for building also through a not very experienced model craftsman. running time was more than half an hour. Only it seems, that the swans don`t like the model very much - the came rather close, but furtunately don`t attak the boat.

Congratulations Thomas.
She looks great on the water.
This is what I call a speed build.

Yes Thomas, Presto appears to be well powered with the revised drive ratio..... :kewlpics .....

.......and as we have discussed, 30 minutes is an adequate running time before the Skipper needs  :coffee

What is the combined rudder throw? [total angle between port to stdb of the rudder which = the tiller angle sweep]

Hi Derek,

the angle of the rudder from neutral to starbord or port is 35, this is sufficient. The turns of the boat are rather narrow for a paddler. Today I will visit my old mother in Rhineland, more than 400 km away. Perhaps I can post some pictures of the boat on a volcanic lake in the nearby Eifel montains next time!

A glad Eastern to all - in spite of the restictions!

Thanks Thomas......I remember the photographs you have of a few of your earlier model paddlers stored at your Mums home.......

So best regards to your Mum during this festive weekend.......a little surprising  :police:  you are allowed to travel that far

Very nice. I like the boiler you made!
A video would be nice too.

I will try to make some further pictures, perhaps a video. But in the meantime the plans of "Presto".
