Last January I've completed the model ship Le Glorieux of Heller.
In June I made the Napoleonic cannon of Mantua. It's now finished and on display.
I'm building the BR 18 Bavarian Dream from the Spanish model manufacturer OcCre. I'd like to share this project with you guys.
Lovely machines! The BR 18 was a Bavarian locomotive, built during the 1908 - 1931 time period. It was not only the biggest machine ever made for its German manufacturer, but it is also being considered as the most beautiful German locomotive.
Some of them are still active! Check out this loc from 1918.
Scale 1:32 / G-45
Height: 153 mm
Width: 100 mm
Length: 720 mm
Wood / metal
With a length of 720 mm it's a very big model! Usually this scale is used in the garden where some hobbyists have laid rails.
I'll make a wooden stand covered with small stones and a rail track. The locomotive's wheels will not touch the rails but this have its wheels rotating by a built-in motor. Besides I'll also make a rail track so I can watch the locomotive move.
I'll also extensively make use of Arduino. This is a name for various cheap electronic boards. A computer board can be programmed by connecting it with a usb cable to the pc.A motor shield can be attached and programmed to make wheels rotate for example.I'll also add a bluetooth shield so I can control it with my phone.
I'm gonna implement the JGY-370 DC 12 V motor, a Massoth 8310101 smoke unit 5 V, LED lights and sound.
Used paint will be acryl, wood glue from Mantua, super glue / epoxy from Bison.
Here are all photos of my progress:
Chassis with a 12 V DC motor attached:
This is what the running gear should look like (Walschaerts valve gear).
When steam is sent to the cylinders it will push the piston and transmit reciprocating power to the wheels.
This is what it looks when attaching connections rods on one side:
Oops! That's didn't quite work. What we're missing here is that steam locomotive drivers are quartered. The crank pins are set 90 degrees apart.
This means that the crank pins on the left side of the locomotive are turning upwards and on the right side of the locomotive offset by 90°(a quarter).
This works for real locomotives as well. Let's bring it into practice:
Enough to do! I'll keep you informed.
