Building the Schaarhörn
« on: November 09, 2020, 02:59:38 pm »

A couple of month ago I bought a kit of the steamship SCHAARHÖRN made by Caldercraft. The kit contains a fiberglass hull, many laser cut wood sheets, about 800 white metal parts, etched brass parts and three plans with very limited instructions.

So far I worked mainly on the hull. I added the drive shafts and two 775 motors, the basic electrical wiring, painted the hull and added some of the deck features. Reading some of the older build logs, this model seems to have, thanks to the weight of some of the white metal parts, a very high center of gravity. I added approximately 2kg of lead in the bottom of the hull and I will replace some of the heavy white metal parts with some plastic items. I will post a few more pictures as soon as there is some progress on the superstructure.

Beautiful hull and an excellent installation of the running gear, look forward to your progress.  :-))

The layout of the RC equipment is very neat and the whole thing looks very good

Excellent electrical installation, you obviously follow the maxim 'neat wiring is reliable wiring'.


Cheers,

Thanks Mike.


In a fairly tight space, the hull is long but very narrow, you can't fool around. I always watch my electrical layout and reliability. I also make individual schematics for every model I build. For the fun of it I do attach the diagram for the Schaarhörn.

Wow! The electronics are so well laid out. As are all your builds. Almost as beautiful under the decks as above.  :-))

Here is some progress on the superstructure. I finished the anchor winch, painted most of the superstructure and worked on the state room. The furniture isn't quite to scale, 1:30 instead of 1:35. I added also a false ceiling with LED lights and the cut out for the skylight. In order to get easy access to the electronics I did split the state room from the main structure.

So Wilhelm......I like the build   :-))
You appear take the power supply from the Port motor 'speed controller', as a convenient source on the unregulated side? for the single Blower Fan Motor
 
 These smallish Pillow Fans will work in dissipating xx units of heat as measured in a reduced thermal gradient of the external motor casing temperature, however needs careful consideration
 
 We also see that this motor in manually switched......however is the fan blowing air downwards?, or drawing heat/air from the motors casings to atmosphere?
 
 
If it is the latter, you could consider some light styrene sheeting to make an exhaust trunk over the fan square body upwards to atmosphere via a vent placed on the external face [companion-way] on deck level. Naturally whatever volume [FAD] of the fan must also be complimented as a ‘greater’ availability of free volume of air entry
If the fan were reversed, it would simply circulate warm air within the hull and superstructure  >>:-(

Hey Derek,
thanks for your information on air flow.
For your information, the fan is blowing air over the motors. Right above the cooling fan are four openings (windows) in the superstructure where the fan can draw fresh air. The circulating air will also cool down somewhat on the wall of the hull which is surrounded by cool water. Furthermore some of the warm air can also vent through the  funnel and another three openings in the ceiling of the superstructure. It should be okay. The first test run in my pond will tell me whether the fan is even necessary. If heat will be a problem I will build a contraption from the four windows to the fan.

I assume that the air circulation will be a minor problem compare to lowering the high center of gravity to a more reasonable level.

Hi Dale,
I managed to make some parts for the upper deck of the superstructure, started the railing and the funnel got a new top made out of plastic. I did find a picture of the stain glass skylight and added it too. Most of the parts in the pictures are still not mounted because I want to finish the lighting for the deck first and the LED's haven't arrived yet.

Hi guys,
as you can see in the attached pictures, I did finish the Schaarhörn. I did add a rotating radar screen, extra lighting, depth markers and a sound module (RAM steam whistle).


I hope you enjoy the pictures.
