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.

Very nice and the electrical installation is so tidy - lovely job :-))
-
Beautiful hull and an excellent installation of the running gear, look forward to your progress. :-))

Thanks guys, much appreciated.
Wilhelm

The layout of the RC equipment is very neat and the whole thing looks very good
-
Thanks Dave for your kind words.

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. :-))

Thank you very much for your special comment, much appreciated.

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.

How's the build coming on Wilhelm, looks great so far.

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.

Looks fabulous Wilhelm :-))
-
Glad you like it. :}
Christmas preparations are taking over and the next update might take some time.
Wilhelm
-
Looks fabulous Wilhelm :-))
Yes, wonderful! :-))
-
Hey Martin and thanks for your kind words, much appreciated. :-)
Wilhelm

Never mind about Christmas, keep on building! {-) Joking aside, she looks fabulous and you're doing a great job. :-))
Hama

Thanks Hama :-) . Good advice but I just can't skip Christmas %)
Wilhelm

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.
Wilhelm
-
Magnificent an excellent piece of work you are to be congratulated :-)) :-))
-
Wow – that turned out really well. Great work.
-
Thanks Phil and Steve for your nice comments., much appreciated.

Wilheim.......
In certain cases, anti-rotation spikes with a 'drop-down' ends were uses between pairs of turn buckles.......easily adjusted, although for standing or fixed rigging the requirement for adjustment is low.....however natural vibration & under tension, can cause rotation
Small lengths of galvanised wire rope were also used, although could look a little out of keeping on a vessel of this style or Class
Derek

Thanks Derek,
that makes sense. Maybe a thin spring loaded split pin, for easy removal, might do the trick. I will look into it.
Wilhelm
-
Yes, make sure it is tidy & not to be a scratch hazard as unbroken wire rope could be <*< .....were all of the Turnbuckles & fastners included in the kit?, or did you purchase them?....Knupfer??...excellent product & people
Maybe a drop of Loctite 243 on each of those M2 brass bolts & nuts.......[easily removable with standard spanners, but will never vibrate loose]
[The Knupfer 3,0 SW [or 3 AF] OE spanner is the standard size for the M2 bolts & nuts] - [10BA is ~~ the same AF size, but the spanners are x 1.5 the head thickness & head diameter]

What great example and such wonderful work
I always hung my nose over this boat, but I could never do what you have
Just brilliant, very inspirational
Love to see some pics on the water
Congratulations on a great build
Thanks for sharing

@Derek,
the M1.4 fasteners and turnbuckles were included in the kit. Too bad that the turnbuckles were made of white metal and for this application definitely useless. The fasteners were of good quality. I did buy the brass turnbuckles from "prime-miniatures" in the UK. Great service and product!
@Seacommander,
thanks for your kind comment. I will post some pictures of her in the water but it won't be before ice out by middle or late April. :((

Hi, this week was the maiden voyage. Everything went well and she really shines on the water. The location of the ballast ( in correlation with the center of gravity) seems to be spot, no problems even in faster turns. I hope you enjoy the pictures.
Wilhelm
-
She looks impressive Wilhelm beautiful build.
Joe.

what a lovely build
-
Fabulous build Wilhelm, she looks stunning on the water :-))
Dale.

Thanks guys, I really appreciate every comment from you. :-)
Wilhelm

Wonderful !!
It's my birthday today, great present to see your model finally on the water
Many congratulations, job very well done
Thanks for sharing
Cheers

Happy Birthday Mark.....and many more! :-)) :-)) :-))
Thank you also for your great comment.
