I made this little video to celebrate my "achievement" 
No music sorry.

Everyone of the 149 soldered joints - and every stretch between them, cleaned with files, the about 15 that broke in the process resoldered, and finally all of it washed and degreased.


You may notice the three "notches" that are soldered onto the hand rail for the installation of the fore and aft indication lights and one foreward working light


Ready to be painted with good timing as the snow is finally melting away and humidity is decreasing each day.

If it were me I'd be more interested how you can get the gold look off those chains on the fenders!  I've not found any fool-proof method out there yet apart from blackening before fitting.

Rich, I stained the chains with matt black enamel. How did I do it? - Very carefully!    You know - the hedgehogs ...

Answers to Capt Podge:

Note : I'm fairly certain your main deck is well fitted against any water ingress...
- the deck itself is water-tight.
- Well, otherwise, hard to admit; I studied the edges of the removable deck and it is actually leaking on the other side over a length of about 10cm ever so slightly. Enough to allow the demonstrated amount of water to enter. - I think this is it. The second day, water was spilling through the forward bullrings and the side flood openings as well. Intermediate solution is tape. A sustainable solution is under pondering.

Ray, I added more of my amazing black liquid sealant mass on the indicated stretch that leaked. We'll see, if it was enough to keep any spilled water outside... The removable sub-deck sits pretty on the main deck now, anyway.


Cheers, Hande

Ready for this year's sailing season.
There was a serious "lay-off" at the dock, pausing all work until the end of the year.

Summary of winter works after the new year:
- re-established the dockyard
- fixed the suspected leak under the edge of the sub-deck
- tuned the fender tyre chains (coloured them black)
- fixed the the port side anchor chain (that let the anchor hang loose)
- replaced the battery
- built the railings, save the ladder that would lead to the top of the wheelhouse
- repaired the main towing winch control panel and ass'y that was originally really very bad (not installed, yet, at the time that the photos were taken)
- repainted the top of the superstructure due to poor workmanship from an earlier attempt.
- drew some wiring for lighting, which will - hopefully - be realised during next winter's work period.
- purchased electronic switches for lighting
- wondered, why the ACTION Noisy thing is misbehaving. Disconnected it and let it stay dormant and wait for a replacement (with something that's not so insanely expensive ). Replaced the loudspeaker with equivalent mass of ballast.
- Found and implemented a tentative solution for the top of the wheelhouse to allow access to the wiring of the lights on the top - essentially inside the wheelhouse proper (for future work on lighting in general)
- Added a minuscule amount of grease in the propshaft tubes and admiring the solution that is basically leak-proof
- installed the mast support wires
... probably something else, too, that I've forgotten.


The railings took most, if not all, of my attention. The result is full of faults, painting went terribly wrong, had to resolder almost 20 joints that I broke. Even the end result still carries a loose joint that I broke in the final step of assembling the gates at the corners in front. I soldered every joint as far as possible. The little gates were challenging because of the short distance that heat could travel from previous solderings to the next one. Finally, I gave in to epoxy glue to install the gates at the ends of the forward section of the main railing. DELFI's railings are actually all-black. I do think black-and-white would be prettier, but this colouring is quite characteristical of DELFI. On the other hand, DELFI is really very black - quite sinister. In my colouring scheme, I imagine her at a state, where she was somewhere in the transition from gay colours of Smit into the practical blacks of Cata.


DELFI, in real life, has a very tall LA antenna, which is depicted at the top. I haven't checked how long it should be in scale.

A dream being fulfilled after 46 years

Ive got to say that does look lovely!

I experimented with different curves to make the ship behave as realistically as I could.
Without any adjustments, every turn was far too abrupt - plus I was afraid that the rudders will break with such fast turns.
Below you can see the present curve (CV1: rdr). It shows, how extremely carefully the servo turns, and even at maximum displacement of the rudder stick, the turn is quite small. The effect is very natural, indeed. If needed, by a flick of a switch, I can override the moderate CV1 and go linear. Maybe in an emergency, or what not.


The CV2: thr is programmed in a similar way. My motors are very powerful and even with 6:1 gear ratio I got kangaroo jumps with a simple linear curve. So, here, too, in order to achieve natural acceleration, the curve had to be tamed. I don't even care to try, how fast the boat would actually go...


For tank steering, you can tell, the CV3: tnk is slightly more agressive, as I want to be able to turn on the spot without too much hesitation. I succeeded.


Programming an "open" system is a lot of fun. I am not restricted by the manufacturer's choice of settings.
I include here the mixes. The code is not very obvious (many Mayhemmers know it better than I, I suspect). In some cases I might say, it's counter-intuitive.

Thank you so much for _your_ support!

Hande...superb build 


Certain engineering functions in model making do not lend themselves to the rules of scale.........the elevation or train of gun mounts visually should be slower than the mathematical scale speed


The same could be considered for rudder function, not visually of the rudder/s themselves, but in the resultant speed [or smoothness] of turn of the model vessel


To overcome any overspeed of the rudder/s, an Action P96 speed controller [servomorph] can reduce the servo speed and also allow alignment of any required set points

Thank you once more for your astute advice, Derek !
As you are one of the first to help me out, when I began the build in January, 2016, there is a nice arc of drama in having your message this close to the finale. This is precious, the Mayhem forum. Without such help, I would have gotten lost on page one already. Alas, we are now on page 21 - amazing!!


Thank you, Derek, for everything!


I thank everyone else, too, who offered advice, and at many instances, kind words of encouragement, without which I'm not at all certain that I would have survived 


I may still post photos or links to videos, but I don't expect them to offer anything drastically new, compared to what I have shared already. Maybe a video of how realistically (or not) DELFI navigates?


Cheers, everybody!

Although it's the end of the build blog, it's not the end of the build, to be sure. Substantial amount of work still remains.
But one has to stop somewhere. This seemed appropriate to me.
There will be no innovation, or even problems.
Just setbacks, which has become a sticky flavour of my build.


I found a new pond near me. The scenery is beautiful, water is clean and clear, I can get near the waterfront by car. Perfect!


Here're the greetings from Siikajärvi, Espoo. Enjoy! (sorry about the quality - it's just phone video. You may get HD quality on Youtube's discretion):

Photographs - much better than video!

So, Hande says..

'I found a new pond near me'   ......a pond is something that kids run & play in ....in OZ...from the video, we would term your pond as a reasonably sized lake


Carry onand enjoy your spare time motoring in your pond   ....why not give us an update sometime in the future

That has turned out really well. Congratulations.
I've been following this build for a few years and your work is meticulous – I wish I was so precise.
I hope that you have another project in mind as I've learned a great deal form some of your building techniques.

[Hande]

Don't you like photographs, you Mayhemmers! First lesson, when I started January, 2016:"Send us photographs - keep them coming!"

OK. This is a shooting session of my "candid camera". Genuine "weathering" from the previous sailing. The, oh-so-many flaws. Cover-ups of my sins with paint, with resin, with glue. Suboptimal solutions to get me out of jam. Etc.

But also, the wind shield wipers. The little gates in the railing. The bridge from the top of the wheelhouse to the bottom of the mast. Working lights over the aft deck (forward coming next winter). Indication lights starboard, portside and stern (forward coming next winter. The genuine Rauma Cata logos in the stacks. In general, I made it! Railings, bulwarks, stacks, winches, bollards, electrics, the overall and inside of the wheelhouse. All this has been very difficult for me. Have I thanked you all much enough for your support? I hope my gratitude has come out articulated enough, repeated enough! It comes from the bottom of my heart.

The tugboat looks fantastic.  it deserves a much better stand than a block of styrofoam
