Model of the paddle steamer DIESSEN (Ammersee/Munich)

[andy]

Hi,

between 1975 and 1978 i built this model when I had finished school. The impression of the horizontal seam engines was in my childhood, when I looked into the engine room at the Chiemsee paddlers. Then In 75 I saw the DIESSSEn running the last year under steam, I took all measurings and plans and started to make this model within 3000 hours. Is running with radio control, about 2m long, scale 1/20, engine and boiler made of inox steel and very light. Complete interior like original and so far. if I would know how to upload the pics, I would do it.

I'm glad you followed the call to join this forum, Andy! It's good to have you here. I'm sure you're wonderful model will be appreciated here.
Could you please tell a little more about the engine? Did you build it? And is the hull made from brass sheet as well, as in your Schondorf steamer?
Because I grew up and lived in Starnberg county until 2 years ago, I'm enjoying being reminded of the wonderful Fünfseenland (how I miss the beergardens...), though I'm too young to have seen the Diessen under steam.

Regards, Moritz

Hi PD's ...& as Moritz says Andy.... ...great build....in some of the .jpgs I was not sure if I was looking at the model or the real vessel.....but so many questions...... 

I can see the two gas tanks, the twin boiler burners, the steam discharge & super heater loop, the lubricator & the lagged line to the engine

1) at the 12.00 o'clock position just under the paddle shaft we see a container with a screwed/flanged top...what is this?...is it engine shaft driven?....does the discharge line go overboard?

2) at about 5.00 o'clock I see a device which connects to the engine near the PORT side steam connection..... what is this ?

3) at about 7.00 o'clock... ...another device which appears to be driven off the paddle shaft......& connected to the boiler...is this a water make up pump?

4) barely visable in this .jpg......but shown in another .jpg is the horizontal tank mounted in the lower engine frame with a screwed/flanged end....just AFT of the paddle shaft what is this ?

5) again in the plan .jpg we see two yollow painted perforated & curved covers in line with both each engine bottom end & also each boiler burner..... ...are these anti splash guards to keep oil spary from the burners?

Again...welcome on board....

Hello Andreas, welcome to the forum. What a fantastic model you have built, like Derek I too was often wondering if I were looking at the real ship. The attention to detail is superb and the quality of the workmanship again is excellent.

No questions from me I'll never get to doing anything as astounding as your model.

regards

Jim

Hi

first to the engine. it is an original- like rebuilt of the Maffei- engine which was in the hull up to 1975. I made it a parallel streaming engine source, for self starting, original it is a compound engine. silver parts i had made in inox steel, because I wanted to see this flashes of light on the running engine. This was a dream of mine. Now I often drive with the big paddlers on the Lake Constance and Lake Lucerne and I like to look into the engine window to the crankshaft. Or- better is to corrupt the engine keeper and to go into the engine compartment, with the tons of gleaming steel moving about you.

And now to Derek´s questions.



I can see the two gas tanks, the twin boiler burners, the steam discharge & super heater loop, the lubricator & the lagged line to the engine.

        Yes these 2 gas tanks are integrated into a model of the original coal bunkers.

1) at the 12.00 o'clock position just under the paddle shaft we see a container with a screwed/flanged top...what is this?...is it engine shaft driven?....does the discharge line go overboard?

        This is the pump for pressing outside the water which comes from the condenser. It is driven by the paddle shaft. But this pump took so much power of the engine, that I decided to unfit its connection to the shaft. Now the engine runs smoother, and the steam blows directly through the valves of the pump.

2) at about 5.00 o'clock I see a device which connects to the engine near the PORT side steam connection..... what is this ?

       Oh, that´s a little model of the original generator- steam engine. 1 cylinder, running well, but cannot be connected to the engine, because it would take too much steam. And for what? Source of the radio control with energy made by steam?? No! But it runs, and its tube is there to let it run sometimes with compressed air.

:-)

3) at about 7.00 o'clock... Hammer...another device which appears to be driven off the paddle shaft......& connected to the boiler...is this a water make up pump?

    Indeed, it is the water pump. Taking the water under the hull, pumping it through the condenser for cooling the steam and getting some heat of the old steam, and then this warm water will be pumped into the boiler by a ball valve. Pump is driven via beams and an excenter from the paddle shaft, you can see it about 5 o´clock.


4) barely visible in this .jpg......but shown in another .jpg is the horizontal tank mounted in the lower engine frame with a screwed/flanged end....just AFT of the paddle shaft what is this ?


This is the condensor, I wrote at top 1).

5) again in the plan .jpg we see two yellow painted perforated & curved covers in line with both each engine bottom end & also each boiler burner..... Thinking...are these anti splash guards to keep oil spary from the burners?

   No, this were protections for security. The crankshaft should not take off the heads of the engine personal. Oil was splashing into the hull.



When I designed this engine according to the original plans, I made one big and one little cylinder, with diameter of 18mm and 34mm. When I calculated, the result only was a power of 1/200 horsepower! So I was not sure, if the engine was strong enough, but I could not believe this. Then I calculated about the torque, and this was 36 kilograms!!!!! So the protections at the crankshaft are needed for my fingers, too. This engine has the power for a model with double size! But the consumption of the steam is comparable to the gas consumption of a Caddy Eldorado of the fifties. Model runs about 15 minutes, then I have to refill the boiler (I did not yet check, if the water pump will give more driving time): if I would do the job with the engine  another time, I would reduce the bore of the cylinders to about 15mm, which seems enough. This was my first steam engine- and the last, too- so I had not the experience in all the details.

Every piston is made of brass and has 2 sealing rings.

The boiler is a 2 tube system, made of inox, too. To get the steam pressure, it only needs about 4 or 5 minutes. THIS didn´t believe some other model constructors, I met during a steamer meeting at Nurnberg some years ago. One asked me, if I had a plan of the boiler, and I had. I am an architect an I was able to design this boiler and to make this plans. 3 years alter, when I met these persons at the same meeting, 3 new models had the type of my boiler, and now there are more!.

The hull is made of brass 0,3mm, soldered. It was made over a gipsen model without stringers, only 2, at the front and the rear end of the engine compartment. here are aluminium walls 1mm, which give the hull its statics against torque. The decks were made of wooden sticks over self made aluminium beams. the alu- beams had a weight of 2 grams unpainted, and painted 5 gramms.
Wheelhouses are made of brass, too, with real rivets 0,8mm.  generally I can say, that every part of the model was made by myself except of electrical bulbs and some screws. In these years (1975-1978) the model world had no fittings in this scale of 1:20 and so I had make all this myself. One problem was the ship to reach a size where the model cold swim. So i have chosen the 1/20 scale which had the result of a possible weight of about 17kg for the ship. This time, a steam engine had a weight of about 5-7kg, a boiler about 10 kg, So I made all wiht very light details. The little steamer, I am constructing now, is more light, because it is only 90 cm long- for this ship I bought a model steam engine from France, a nice fine made model. Boiler now is under construction, too.

Have you seen on the black/white pics without the deck, that the hull has all the original furniture in it?

Hi PD's & .....thanks Andreas...for the comments......as I mentioned...the steam component is very interesting to many PD members....the sub model single cylinder steam engine & ?? thing had me really mis-understood...but I can visulise the slow reving DC generator now

If you have other photographs or sketches & comments about this build or you current new build...please post them....you could start your own Subject Folder in Live Steam.......called PS DIESSSEN

Then we could ask Eddy to transfer all of the previous postings to this new Folder

Adding .jpgs is not difficult...just go to Additional Options to the lower left of screen & the instructions are pretty well self explanatory...but if you have any questions just ask.......someone from around the world will assist - regards

Hi Andreas,
That is absolutely stunning. A beautiful model should be considered equal to a priceless work of art. every tiny detail faithfully reproduced, fantastic. Thank you for allowing us to see your work.
Kind regards
Malcolm

Hi,

where can I find this folder LIVE STEAM?

Indeed, i have some more pics, I will see to add them to this picasa album, and later to the folder.

Hi,

here the album of the little sister of the DIESSEN, named SCHONDORF. No paddles, but propelled. Built in 1909, wrecked in 1956, when I was born. It was nice, when it is finished, to put the two models into the water here at the Ammersee with a little wooden bridge, and then take photos with the background of the landscape of the Ammersee. Thies model will take one year for the finish.

And here some toys, I am working, too, some of them have good torques, too.

I've rarly seen a collection combining excellent taste, non-conformance with the mainstream, and cost-consciousness like this. Brilliant! You're obviously a man of great taste and high motivation.
