Hande...the winch detail looks  :-))...... the electric motor for the main towing winch is shown as a foot mounted motor with an exposed output shaft attached to the first stage reduction of the winch gearbox

In most marine winch builds, the motor is flange mounted to the gearbox, eliminating the exposure of the motor output shaft, the coupling and the input shaft to the gearbox etc

When I spoke of IP68 previously it was not intended as a joke, but for you to understand what real marine winches require in terms of water ingress resistance & hence electrical protection

You have used the flange mounted electric motor to the anchor gearbox winch  O0

Thanks, Derek!
I actually am an electrical engineer and have some understanding about electrical protection. I admit, I thought you were joking  {-)


As for the choices about the design, I follow plans provided by Billing Boats. More importantly, I use parts of the kit. This is my first build of this scale. And I haven’t built anything for 40 years...  :((


Nonetheless, I keep your expert advice as precious resource for my upcoming projects - although I doubt whether I will gain self-confidence for a scratch build.


About the exposed output shaft (I was wondering where it was inside a pipe, or indeed exposed). Do you suppose, it would not be white, but rather some ”greasy” colour?


I’m grateful for your comments - thanks again!

Btw, what is the function of the mysterious (to me, that is) two-pinned fork that does show in photos of the real towing winches, too? The kit includes one and I dropped it between the gearbox and the hawse drum as directed, but the pins don’t touch anything and there it hangs loose, bound to drop one day. I am thinking about attaching it permanently.

Could it be an emergency break? It seems, if one would pull it back, It would jam the cogwheel that sticks out from the gearbox.

Additional information:
My build ”boasts” (free) spinning hawse drum and anchor windlass axel.
For me, it was not trivial, anyway  :embarrassed:

Thank you, Taranis!
your message made me feel responsible... toward people that check out my blog in uncomprehensible numbers. I am sorry about the lack of progress! [size=78%]I have had domestic affairs to an extent that my build has suffered.[/size]
[/size]
I am still fixing the bulwark. Hard to keep up the spirit, when there seems to be no visible progress.
The file and other tools keep slipping and spoiling completed surfaces here-there - always at the few spots where I had already done a decent job. If this a hobby with ups and downs, this is one of the downs.

Sound generator test.
I use Action P110. I got the sound of double-diesels from Component shop, at the show last year. Works like charm!


The loudspeaker may well do. It is high quality - cannibalised from a radio that otherwise went defunct.


It will be important to introduce a speaker-box for a fuller sound, as shown here (the round bottle tube that happens to be just right size)
I wonder if the hull itself will act as a sufficiently closed speaker-box, or if the loudspeaker should be in a speaker-box inside the hull.


How do you install your loudspeakers?


cheers!

Happy new year Hande
I have not done this type of sound system but I believe the speaker sound is enhanced by fitting to a baffle board.
Personally I chose a cheap all in one sound box made for 4X4 RC vehicles so had no need for such a solution to speaker mounting.

Same unit applied to low RPM tug. However there is some background noise from another sailor

Hande if you want some oppinion on sounds I think the lifeboat hull, albeit on the workbench sounds great for that type of vessel.  Very like an old JJC sound board I have.  The video of the tug though I'm afraid for me at least demonstrates where something sounds impressive, but doesn't actually work in that application.  A tug of that size would probably never sound like that -it makes it sound like a toy to me.  Sorry!

I suppose that the hull provides for a speaker box in itself, although its size is out of proportion.
Adding another box (in a box, effectively) may muffle the sound and strip it from high frequencies?
The result may sound like the engine is buried under a pile of pillows.
On the other hand, in the air without any speaker box, low frequencies are lost and the sound is toy-like.
And then there is the effect of water. What does it do to the sound?
In the bench, the sound of the electric motors is too loud and disturbs the twin diesel sound of the sound generator.
Just wondering. Cannot test my theories for a while, as the build is not ready to be put together and in the water, yet.
Thanks for comments, everybody!

A long break, I know...
I hope to return to my build, soon!


Meanwhile, I spliced the main hawse rope. Not perfect again, but I'm learning to live with imperfections.

A little progress. I have been working on the bulwark still: cleaning and painting. Got tired of that and turned to fendering.

Fendering is coming to place gradually.
As per instructions of Billing boats, I used long strip.
Sanded and primed before cutting to approximate length piece by piece.
As the fender pieces will go around the edge, the profile had to be adjusted - I overdid the provision for the turn, but the little room that will be left between pieces will fill by glue, I expect.


As the fender pieces are now, they look what they are - wood. As the original real tug was built in 1978, I wonder, if the fendering was actually made of logs/wood. In photographs, it looks like each fender piece is attached individually. Essentially, each piece would hang individually.

That's why I used an old toothed timing belt Hande. I had the same problem as you but I gave up after just 3 pieces of the wood strip  O0


Good to see you're still working on the model anyway.

Thank you, Ray - that's kind!Her-inside outside, home alone - what does man do  ok2
Have to turn back to finalising the bulwark, now.


Holidays over this week, I'm expecting the usual slow pace from here.

I'm still here.
Working on the bulwark, learning to use different kinds of putty.
Problem is with the little scratches. You think you have smoothed them out, but after sanding - there they are again! Wrong putty, wrong technique, wrong sander?
I never seem to get to painting...

RETIREMENT!
Am I going to spend more time on my build, or what!


I made the following findings while searching for some new fotos:


1. There is a distinctive difference between Smit Nederland and Smit Finland and other sisters. You can tell, it's Smit Nederland even if you cannot read the name. S.N. has a vertically extended bulwark in bow. This is why the Billings kit has that shape. Since I am building Smit Finland, I removed the extension. All well!


2. A further sister, Smit Ierland, is the same shape as Smit Finland. More importantly, she is presently sailing under the Finnish flag, with the name DELFI. My original plan has been to build the UREKA IV (ex- Smit Finland), because - well you know - she's originally Smit FINLAND. But as UREKA IV is misbehaving (not engaging the AIS for positioning) I am thinking about changing the plan and divert to DELFI.


3. DELFI has got a crane nowadays. I will self-educate myself on building cranes. Future will tell, if I ever learn  :}


Btw, Smit Japan is also in Finland, with the name LEONARDO. But she is not sister to Smit Nederland.

Hello Hande, if only it were that simple. I retired at the back end of December with the same notion - and have yet to get anything done on the models.
All those little jobs have been piling up and, along with a bout of illness, there's just not been any time for tinkering in the workshop.
Anyway, it's good to know that you are getting back to your model now.


Regards,
Ray.

Marking the water line.
I decided to go by the scratching method. Didn't trust any marker or pencil.
We shall see, if I can fill the scratches in the end of the day...


I took a new blade and attached the cutter as shown. I figured, it is so sharp that I only need to touch slightly to make a mark on the paint.


In aftersight I see a number of mistakes in my thinking - can you?

I had troubles in the beginning. I started from the stern and proceeded towards the bow.
The other side the same from stern to bow. Coming from the other side my lines touched at the bow just  :D

The problem especially in the beginning (portside stern) is that the cutter is so long and operated from so far away from the surface that it really wasn't very robust at all and kept moving. Also the blade - although stiff to the finger, bent up and down and here-there made annoying curves along the hull surface. I couldn't see well into the underside of the stern and only afterward saw, what kind of mess I had made  >>:-( . The second try starboard went well, however. The correction was made by freehand trying to achieve symmetry with the starboard side line.

The lesson learnt:


Should you try to scratch - which I'm very much in doubt about now - scratch backward (the back of the blade first). That way the blade isn't bound to eat into the surface. Draw the blade instead of pushing. The tip is indeed so sharp that it makes a mark also backward.


My waterline is fine, but there is correction to be done stern-portside.

Btw - don't worry about the colours. I don't know why the red seems so ridiculous in some photos. The real thing is "dull".

(font problems, again...!)

My takeaway from your experience is that I should use some kind of marker (a really soft pencil I am thinking) that will leave a line given only the lightest of pressure.  Also, the contraption holding the marker needs to be quite substantial.


Thanks for the warning.
