SS Bohuslän by uheynitz - Billing Boats - 1:50

Dear colleagues, after my BOHUSLÄN thread was unfortunately hijacked, I deleted it and repost my content. Therefore, the request to all who are concerned: Publish your models in their own threads and do not use foreign threads for discussions with other members of the forum. Thanks!

Since the weather is subterranean right now, and I don't have too much to do, I will continue with a project that has been close to my heart for many many years: the SS BOHSULÄN.
When I was 18 years old, I had bought the kit, and immediately put it aside, because it seemed much too difficult to me at that time. Then I had lost the kit, and at the same time the kit was no longer produced by Billing Boats. Sh...
In the meantime there were several producers who tried their hand at the BOHUSLÄN, with more or less success. At the moment there is still a kit that is distributed by Krick. However, this kit is out of the question for me for several reasons, mainly because it does not match the original in many points and proportions.
The BOHUSLÄN is still based in Gothenburg and makes many trips there every summer. There is a very active Facebook group where you can view many photos and videos of the BOHUSLÄN.

About the build:
In the meantime I fortunately own two construction kits from Billing Boats, which has the advantage that you can sort, use or sort out the good and the bad parts from each kit.
 

I also planked and laminated the hull a year ago; this will be finished soon.

Eye-catchers on the steamer are in any case the beautiful teak panels, I had these milled so that no crooked windows creep in here.

 

This is what it will look like at some point:

 

The BOHUSLÄN is getting a double main deck to get to the engineering.
Since this has a decent deck jump, I have form-glued the two decks and now continue to build on a deck jump gauge so that this does not "lose" itself.

 

 

Only when the superstructure is finished is the hull jump adjusted so that everything fits nicely.
This is an unusual way of working for me. I usually always build from the bottom up.

 

 

After half a day it looks like this:

The deck, previously painted black, is covered with mahogany planks. There is nothing between the planks yet, but I have made a few promising attempts with black colored putty.

 

[uheynitz]

The art of the vague...
...or just missing is also over. Or as Franz would say, " Passt scho."
Sometimes I think that the term "fit inaccuracy" was coined for wooden construction kits of the 60s and 70s, and then especially for Billing Boats. Mismeasurements of 3mm are unfortunately not uncommon with the "BOHUSLÄN", which also explains why the lines printed on the wood are up to 1mm wide (Because then it's always the modeler's fault...).

No matter, then just something is glued (we are model builders), and the result is then - hopefully - a really nice steamer.

 

[uheynitz]

I love it when the hull is smooth as a baby's bottom after a few spatula & sanding passes.
Today is the last sanding with 400 wet, then the rub rails, rudder hook and portholes. 
And then off to the garden for painting.

 

For the portholes in the hull, Billing Board included injection molded parts (the gray porthole), which is way too rough for me. 
So I invested in brass portholes without imitation screws (the portholes in the original are not attached...) (brass porthole on the left), but they look like glued-on rivets - like portholes from 60s kits.

 

 

 

[uheynitz]

As I mentioned before, I like the hardware set in the kits from Billig Boats. There are many finely detailed brass parts. I was particularly taken with the funnel of the "Bohuslän". A really beautiful part!

 

And then this:
I have kept the whole once to the construction plan. The funnel is no less than 3 mm too small in diameter. This is a medium catastrophe for a scale of 1:50 and not to be tolerated at all.
I had already wondered why the chimney looks so spackelig with the many beautiful Bohuslän models.
So new construction.
So I sat down at the computer and redrew the funnel in Fusion 360 and printed it out on my filament printer.
Here is a first result with printed reinforcements:

 

[uheynitz]

The Bohuslän has - like most steamers from this period - a "sharp" keel.
This is ignored in the kits of Cheap Boats and NCB.
I represent this with the help of T-profiles. These are available from architectural supply stores in PS or brass.
Since the profile may have to withstand some driving, I use brass.

Where necessary, they are bent into shape and soldered to a pin every few centimeters to hold the profile in the fuselage.
After roughening the gluing surface, they are glued with Endfest. The combination holds excellently.

Hi Uwe,

you mentioned sharp keel by means of brass profile and to withstand rough driving...It looks very nice

Are you intending to RC control the steamer on the water ? I did this with my boat in the beginning but had to relialize that moisture was creeping into the planking under the paint indicating several mini-cracks so I refrained from that and have a stand model instead since then

Hi, Nils,
yes, the BOHUSLÄN will sail remotely.
The hull is completely covered with fiberglass mat and epoxy and should be tight.
Inside I have impregnated it with G4. It's almost a plastic hull now.
Greetings, Skip

[Mirabell61]

Hi Uwe.

very nice solution for the water-tightness. Are you still able to hold the intended waterline (weightwise)

 

Nils

[uheynitz]

I hope so!
My rule is: everything heavy off the top and in the bottom.
That's why I also 3D printed the beautiful brass funnel new. Now it weighs only a quarter.

In addition, the boat is equipped very spartan. Motor, small servo, receiver. No sound module, light batteries.

Encore une fois désolé et avec toutes mes excuses pour cette mauvaise utilisation de votre fil.

Cordialement et bonne continuation pour la suite de la construction.

On attend la suite.  😒

 Nothing beats a few lead batteries to hold things in place. I use this technique a lot.....

Dinghies & Skylights

For the Bohuslän dinghies, I had decided early on to 3D print, having found a great and suitable STL.
My first prints from PLA were unsatisfactory. When I printed the boat in one piece, I had to work with support structures that destroyed the whole delicate planking display.
When printing from two pieces (front and back), I didn't need support structures, but I couldn't quite get rid of the seam at the glue line.
In the end, I printed the boat in resin and split it lengthwise, and I'm completely satisfied with that.




 

Foundation of the funnel
This is a mix of construction methods per excellence. The funnel itself I printed out of PLA and glued soldered brass tubes to it.
I assembled the skylight classically from PS and printed the fans in resin.
Then I got the urge to experiment and printed the whole ensemble again in resin.
The result is strikingly good, but more than three times as heavy as the "mix" version.

 

Skylights
The skylights are included with the hardware set as beautiful all-brass parts.
This is nice, but unfortunately also unusable.
So I printed them in transparent resin, which is still covered with etched brass struts.

Nice work Uwe,

its good to see how the 3-D printing method can be of help for tricky details. I like the printed boat halves
