Drawing of the locomotive.
This is a CAD drawing about the model.
It was made 1:1 to the model, 1:87 to the prototype.
Drawing of the locomotive.
This is a CAD drawing about the model.
It was made 1:1 to the model, 1:87 to the prototype.
The first frame design, with only 2 driven wheelsets. The others were forseen
to be driven by the rods.
The second frame design with all wheel drive. The spacers were 5x5mm (0.2x0.2")
brass rods, screwed to the framesides. Unfortunately the gearshaft hole distances
were rather small, resulting in bindings between gears.
Drawing of the new frame design. The new design has space for the worm shaft
bearings too.
Spacer rods between the framesides.
In the new design they are soldered to the framesides giving a rigid structure.
The rod drive. You can observe the Kandó-triangle.
Pieces of the rod and the Kandó-triangle.
The rods were made from brass I-profiles.
The center sandbox with two sandpipes.
The air reservoir.
The invisible back side is carved out to make place for the leading wheelset in curves.
The drawing of the fan cover. The CAD drawing was used to program the CNC
drill machine that made the 6 holes atound the center.
The windows and doors of the loco.
These drawings were used to make the artwork for the photo etching of the frames.
Drawing of the roof ventillation superstructure.
On the model it was built from 11 pieces.
The round part was turned and cut.
The box has separate walls and top and the louvres a separate frame.
