Hello community

I just registered here in the forum.
My name is Dieter and I am located in south/west of Germany.
Last year I finished working and I reached a new milestone in my live: retirement.

Since a young boy, my hobby was RC model airplanes and all kind of mechanics.
At the very early 1980th, I was building more or less successful a few model airplane engines, by scratch build.
During the years, I added interests like Harley Davidson motorcycles, model steam engines and vintage tractor to my hobbies.
Here in my 150 miles radius around "home base", I have several friends who build steam engines and internal combustion engines by them self.

Sorry if my English is sometimes not correct at all, but I am not a native English-speaking person.
(My German is going much better.)

My first activities here at the forum will be mainly reading article from members.
Then in step two, I will start building a Henry Ford first engine, to find back into internal combustion engine building after more than 40 years.

My professional training is as a toolmaker and master mechanic.
Now, I have to work with small and simple lathe and milling machine at hobby size.
(Improvisation is necessary)

Best regards, Dieter


If anyone wants to know where the user name GRAUBELE comes from,
the picture shows a model aircraft with the name GRAUBELE-III from the year was constructed in 1939.
(My current model airplane project.)

Welcome Dieter-

Glad to have you.

I was pretty deep into control line and RC model airplanes in the early days, which must have been perhaps 1976, or a bit before.

I acquired too many hobbies, and so got rid of the RC airplane hobby and most of my planes.
I still have my control line plane, and there are no batteries to charge in order to fly it.
I can do a 180 overhead and turn out upsidedown, and fly upside down (at least I could in the day, maybe still?).

I would really like to build a powered glider of sorts.
I have a design for it (picture attached).

I have been into steam engines since I saw my first Wilesco at age 5.

I am trying to get into IC engine building, but am finding that more challenging than steam engines, due to having more moving parts than a steam engine.

Good luck in your endeavors.

Those are some very nice tractors and stationary engines.

My dad had a Ford Model A golf course tractor, which was made by some company; I forget the name.

I will have to look for a photo of it.
Very primitive looking.

Hello everyone

I've been looking around here in the forum for about a month now and have already given one or two small inputs.
Today I would like to give you a brief overview of the projects that have been started and which are lying around here.
I'll get to some of the already finished projects later.

1. project steam engine ANNA, a cast parts set from Atelier MB in Switzerland.
Bore 25 mm (0,984 in)
Stroke 26 mm (1,023 in)

http://www.ateliermb.ch/ds/Gusskatalog1019.pdf


Casting-set-ANNA-resize.jpg


Current construction status, already functional with compressed air, with a functional self-made alternator.
Steam operation takes place after completion.

To be continued.
 
2. project steam boiler, a tried and tested design from a friend of mine.

Total volume 5 liters (305 in3)
Usable water volume ~3.5 liters (213 in3)

Base plate, 2 mm (0,078 in) sheet steel on a wooden frame.

Water pressure test at 12 bar (~ 174 psi) for 1 hour.

Gas burner with housing.

Goal: model for construction.

To be continued.
 
3. project, restoration of a pre-World War II steam engine.

Takeover condition.

As far as the larger projects that have not been completed.
Now there is a completed steam system after restauration with a new 2 liter (122 in3) steam boiler and another self-made power generator.

Then a short trip to the model airplane combustion engines I built myself.

6,5 cc (0,396 in3) two-stroke boxer engine.

6.5ccmBoxer_010.jpg


20 cc (1,220 in3) four-stroke engine.

Viertakter.jpg


1,6 cc (0,097 in3) two stroke V-Twin "COX" engine.

COX_V_004.jpg


14,3 cc (0,872 in3) two stroke Felgiebel replica engine.

That's all for a rough overview of what's going on here at the moment.
One of the next new projects will be the Henry Ford first engine.
And lots of little gap-filling activities. ;)

Regards
Dieter
 
Dieter-

You have some very interesting engines, boilers, tractors (you name it).

And beautiful countryside too !

Thats for posting the photos.

Great engine/boiler/generator work.
Great videos too !

I am following along for sure.

Hello Pat

You're right, I actually forgot to mention the vintage tractor.
Here are pictures of the current "construction progress".

KRAMER K12V

built in 1950
displacement 1100 cc (67,126 in3)
performance 12 hp
top speed 15 km/h (9,3 mi/h) :cool:

He can already drive, but the lighting is not yet connected with a cable.
I still have to do all the electrical work.

Hello Tony

The generator is not a kit, it is self-made.
I had help from friends with the cast models and the aluminum casting.
In 2007, 32 cast kits were made and distributed among members at cost in a German steam engine forum.
At that time, I did the electromechanical design and project management,
as well as the production of the first functioning prototype and the construction description.
At that time, this developed into a team event in the German steam engine forum.

That tractor is a real beauty.
I need one of those.

Hi Dieter I really like the generator you made! So I have two questions about your generator, In the photo it shows three wires coming out of the generator so is it generating three phase? Where did the stator windings come from? I did the same thing using a bread maker single phase motor and used four magnets to generate single phase A.C. Have a look at my video making it.
 
Hi "100model"

Question one:
Three wires coming out of the generator so is it generating three phase?
Yes there are three wires coming from the stator.
A three-phase alternating current is generated in a star connection.
The generator was calculated to produce approximately 12 - 15 volts at approximately 300 rpm.
This makes it very suitable for operation with a model steam engine.

"Sternpunkt" = star connection (Y)

Winding scheme:

Bridge rectifier:

Question two:
Where did the stator windings come from?
The stator windings come from me.
The main difference between my generator and yours is,
I didn't convert an existing electric motor, I designed a new generator.
The operating principle was adopted by a three-phase brushless model aircraft electric motor.

Spule_einlegen01.jpg


Spule_einlegen05.jpg


Stator: 12 coils with 85 windings each.

Rotor: 32 neodymium magnets (16 pole pairs)

Rotor_19_Magnete.jpg


Every motor is also a generator.
Every generator / alternator (?) is also a motor.
(But with a brushless motor you need a controller that generates the rotating field.)
